三大框架整合
一、SSH导包
二、书写Spring
三、书写Struts
四、整合Spring与Struts
五、书写(与整合)Hibernate、引入c3p0连接池并使用hibernate模板
六、整合事务
--完成用户登录
项目已上传到github 传送门
在MySQL数据库中创建spring表,添加一条假数据
一、SSH导包
导入struts的jar包
导入spring的jar包
导入hibernate的jar包
导入c3p0连接池jar包和springapo的jar包,mysql链接数据库驱动包,第四个spring整合包暂时不需要导入,下文导入的时候会说!!!
二、书写Spring
准备applicationContext.xml作为spring的配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> </beans>
编写web.xml
<!-- 让spring随着web项目的启动而启动 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 读取配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param>
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>SSH</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 让spring随着web项目的启动而启动 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 读取配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> </web-app>
三、配置struts
准备struts.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd"> <struts> </struts>
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd"> <struts> </struts>
在web.xml中开启struts
<!-- 让struts启动 --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>SSH</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 让spring随着web项目的启动而启动 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 读取配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 让struts启动 --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
四.1、书写Action,并在struts.xml中开启动态方法调用
package com.Gary.domain; public class User { private String id; private String username; private String password; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <!-- 配置包名字 --> <hibernate-mapping package="com.Gary.domain"> <!-- 配置包类和数据库中的哪个表对应 --> <class name="User" table="user"> <!-- 主键 --> <id name="id"> <generator class="uuid"></generator> </id> <!-- 普通字段 --> <property name="username" column="username"></property> <property name="password" column="password"></property> </class> </hibernate-mapping>
package com.Gary.web; import com.Gary.domain.User; import com.Gary.service.UserService; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; public class UserAction extends ActionSupport implements ModelDriven<User>{ public User user = new User(); private UserService userService; public String execute() throws Exception { boolean success = userService.findUser(user); if(success) { return "toIndex"; }else { ActionContext.getContext().put("error", "用户名或密码错误!!!"); return "login"; } } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } @Override public User getModel() { return user; } }
package com.Gary.service; import com.Gary.dao.UserDao; import com.Gary.domain.User; public class UserService { private UserDao userDao; public boolean findUser(User user) { User temp = userDao.findUser(user); return temp == null?false:true; } public UserDao getUserDao() { return userDao; } public void setUserDao(UserDao userDao) { this.userDao = userDao; } }
package com.Gary.dao; import org.hibernate.Session; import org.hibernate.query.NativeQuery; import org.springframework.orm.hibernate5.support.HibernateDaoSupport; import com.Gary.domain.User; public class UserDao extends HibernateDaoSupport { public User findUser(User user) { Session session = getHibernateTemplate().getSessionFactory().getCurrentSession(); String sql = "select * from user where username = ? and password = ?"; NativeQuery query = session.createSQLQuery(sql); query.setParameter(1,user.getUsername()); query.setParameter(2, user.getPassword()); query.addEntity(User.class); User result = (User) query.uniqueResult(); return result; } }
<struts> <!-- 开启动态方法调用 --> <constant name="struts.devMode" value="true"></constant> <constant name="struts.enable.DynamicMethodInvocation" value="true"></constant> <package name="ssh" namespace="/" extends="struts-default"> <!-- 允许所有方法 --> <global-allowed-methods>regex:.*</global-allowed-methods> <!-- 配置Action --> <action name="UserAction_*" class="com.Gary.web.UserAction"> <!-- 配置结果集第一个为转发,第二个为重定向 --> <result name="login">/login.jsp</result> <result name="toIndex" type="redirect">/index.html</result> </action> </package> </struts>
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd"> <struts> <!-- 开启动态方法调用 --> <constant name="struts.devMode" value="true"></constant> <constant name="struts.enable.DynamicMethodInvocation" value="true"></constant> <package name="ssh" namespace="/" extends="struts-default"> <!-- 允许所有方法 --> <global-allowed-methods>regex:.*</global-allowed-methods> <!-- 配置Action --> <action name="UserAction_*" class="com.Gary.web.UserAction"> <!-- 配置结果集第一个为转发,第二个为重定向 --> <result name="login">/login.jsp</result> <result name="toIndex" type="redirect">/index.html</result> </action> </package> </struts>
提交登陆<form>表单
<form action="${pageContext.request.contextPath }/UserAction_login" method="post"> <div class="register-box"> <label for="username" class="username_label"> 用 户 名 <input maxlength="20" name="username" type="text" placeholder="您的用户名和登录名" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="other_label"> 密 码 <input maxlength="20" type="password" name="password" placeholder="建议至少使用两种字符组合" /> </label> <div class="tips"> </div> </div> <div class="arguement"> <input type="checkbox" id="xieyi" /> 阅读并同意 <a href="javascript:void(0)">《你问我答用户注册协议》</a> <a href="register.html">没有账号,立即注册</a> <div class="tips" style="color: red"> <s:property value="#error"/> </div> </div> <div class="submit_btn"> <button type="submit" id="submit_btn"> 立 即 登录 </button> </div> </form>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="s" %> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <link rel="stylesheet" href="css/head.css" /> <link rel="stylesheet" type="text/css" href="css/login.css" /> </head> <body> <div class="dvhead"> <div class="dvlogo"><a href="index.html">你问我答</a></div> <div class="dvsearch">10秒钟注册账号,找到你的同学</div> <div class="dvreg"> 已有账号,立即 <a href="login.html">登录</a> </div> </div> <section class="sec"> <form action="${pageContext.request.contextPath }/UserAction_login" method="post"> <div class="register-box"> <label for="username" class="username_label"> 用 户 名 <input maxlength="20" name="username" type="text" placeholder="您的用户名和登录名" /> </label> <div class="tips"> </div> </div> <div class="register-box"> <label for="username" class="other_label"> 密 码 <input maxlength="20" type="password" name="password" placeholder="建议至少使用两种字符组合" /> </label> <div class="tips"> </div> </div> <div class="arguement"> <input type="checkbox" id="xieyi" /> 阅读并同意 <a href="javascript:void(0)">《你问我答用户注册协议》</a> <a href="register.html">没有账号,立即注册</a> <div class="tips" style="color: red"> <s:property value="#error"/> </div> </div> <div class="submit_btn"> <button type="submit" id="submit_btn"> 立 即 登录 </button> </div> </form> </section> <script src="js/index.js" type="text/javascript" charset="utf-8"></script> </body>
四.2、整合Spring与Struts
导入struts2-spring-plugin-2.5.16.jar整合包
在stuts.xml中让spring管理Action的创建
<!-- 让spring管理Action的创建 --> <constant name="struts.objectFactory" value="spring"></constant>
在applicationContext.xml中配置web层、service层、dao层的<bean>元素
<!-- 配置userAciton --> <bean name="userAction" class="com.Gary.web.UserAction" scope="prototype"> <!-- 注入userService --> <property name="userService" ref="userService"></property> </bean> <!-- 配置userService --> <bean name="userService" class="com.Gary.service.UserService"> <!-- 注入userDao --> <property name="userDao" ref="userDao"></property> </bean> <!-- 配置userDao --> <bean name="userDao" class="com.Gary.dao.UserDao"> <!-- 注入sessionFactory (用到了HibernateDaoSupport) --> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 配置userAciton --> <bean name="userAction" class="com.Gary.web.UserAction" scope="prototype"> <!-- 注入userService --> <property name="userService" ref="userService"></property> </bean> <!-- 配置userService --> <bean name="userService" class="com.Gary.service.UserService"> <!-- 注入userDao --> <property name="userDao" ref="userDao"></property> </bean> <!-- 配置userDao --> <bean name="userDao" class="com.Gary.dao.UserDao"> <!-- 注入sessionFactory (用到了HibernateDaoSupport) --> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
五、整合Hibernate、引入连接池并使用hibernate模板
在applicationContext.xml中整合Hibernate
<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="jdbc:mysql:///spring"></property> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="user" value="root"></property> <property name="password" value="123456"></property> </bean> <!-- 配置sesisonFactory --> <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 配置dataSource --> <property name="dataSource" ref="dataSource"></property> <!-- 配置基本属性 --> <property name="hibernateProperties"> <props> <!-- 方言 --> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop> <!-- 生成表策略 --> <prop key="hibernate.hbm2ddl.auto">update</prop> <!-- 是否生成sql语句 --> <prop key="hibernate.show_sql">true</prop> <!-- 是否格式化sql --> <prop key="hibernate.format_sql">true</prop> </props> </property> <!-- 读取orm元数据 --> <property name="mappingDirectoryLocations" value="classpath:com/Gary/domain"></property> </bean>
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="jdbc:mysql:///spring"></property> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="user" value="root"></property> <property name="password" value="123456"></property> </bean> <!-- 配置sesisonFactory --> <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 配置dataSource --> <property name="dataSource" ref="dataSource"></property> <!-- 配置基本属性 --> <property name="hibernateProperties"> <props> <!-- 方言 --> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop> <!-- 生成表策略 --> <prop key="hibernate.hbm2ddl.auto">update</prop> <!-- 是否生成sql语句 --> <prop key="hibernate.show_sql">true</prop> <!-- 是否格式化sql --> <prop key="hibernate.format_sql">true</prop> </props> </property> <!-- 读取orm元数据 --> <property name="mappingDirectoryLocations" value="classpath:com/Gary/domain"></property> </bean> <!-- 配置userAciton --> <bean name="userAction" class="com.Gary.web.UserAction" scope="prototype"> <!-- 注入userService --> <property name="userService" ref="userService"></property> </bean> <!-- 配置userService --> <bean name="userService" class="com.Gary.service.UserService"> <!-- 注入userDao --> <property name="userDao" ref="userDao"></property> </bean> <!-- 配置userDao --> <bean name="userDao" class="com.Gary.dao.UserDao"> <!-- 注入sessionFactory (用到了HibernateDaoSupport) --> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
在web.xml中扩大session范围【扩大session范围<filter>一定要放在启动struts上】
<!-- 扩大session范围 --> <filter> <filter-name>openSessionInView</filter-name> <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSessionInView</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>SSH</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 让spring随着web项目的启动而启动 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 读取配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 扩大session范围 --> <filter> <filter-name>openSessionInView</filter-name> <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSessionInView</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 让struts启动 --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
六、整合事务
在applicationContext.xml中配置事务
<!-- 事务的核心管理器 --> <bean name="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <!-- 需要sessionFactory --> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 通知 --> <tx:advice id="advice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- 织入 --> <aop:config> <!-- 切入点 --> <aop:pointcut expression="execution(* com.Gary.service.*.*(..))" id="pc" /> <!-- 配置切面 --> <aop:advisor advice-ref="advice" pointcut-ref="pc" /> </aop:config>
