介绍:
SSH即struts+spring+hibernate的一个集成框架他们各自是
struts:控制器 spring:调度 hibernate:操作数据库
SSH框架从业务逻辑上分为四层:
Dao层:数据访问层:使用hibernate链接数据库(增删改查)操作
配置:在spring的配置中进行文件配置
Service层:业务逻辑层:负责业务模块的设计逻辑,设计接口,再设计实现的类
配置:在spring的配置中进行配置
Controller层:控制器层:调用Service层的接口来控制业务流程。
配置:在spring的配置中进行配置
View层:表现层:与Controller层紧密联系,主要负责前端jsp页面展示.
开整:是在eclipse上的简单的项目:
1:建一个maven项目:**
完成以后点Finish
建成功以后他会报错那是没有web.xml文件,步骤如下:
单击选中项目右键如下图:
2.接下来配置一下tomcat:
3.配置pom.xml文件,数据库是mysql
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.zy</groupId> <artifactId>ssh</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <!-- 版本信息都统一放入此处,方便以后管理--> <properties> <springVersion>4.3.1.RELEASE</springVersion> <hibernateVersion>4.3.5.Final</hibernateVersion> <jstlVersion>1.2</jstlVersion> <taglibVersion>1.1.2</taglibVersion> <servletVersion>3.0-alpha-1</servletVersion> <jsonVersion>1.9.13</jsonVersion> <jacksonVersion>2.5.0</jacksonVersion> <mysqlVersion>5.1.38</mysqlVersion> <c3p0Version>0.9.1.2</c3p0Version> <log4jVersion>1.2.17</log4jVersion> <fileuploadVersion>1.3.1</fileuploadVersion> <lombokVersion>1.16.10</lombokVersion> </properties> <dependencies> <!-- 单元测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${springVersion}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${springVersion}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${springVersion}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${springVersion}</version> </dependency> <!-- spring web + spring MVC--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${springVersion}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${springVersion}</version> </dependency> <!-- hibernate配置--> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernateVersion}</version> </dependency> <!-- hibernate 缓存, 视情况添加--> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>${hibernateVersion}</version> </dependency> <!-- jsp页面使用的jstl支持--> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstlVersion}</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>${taglibVersion}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servletVersion}</version> <scope>provided</scope> </dependency> <!-- DataBase数据库连接 mysql包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysqlVersion}</version> </dependency> <!-- 数据库连接池--> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>${c3p0Version}</version> </dependency> <!-- json数据 使springMVC可以返回json值 ,视情况添加--> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>${jsonVersion}</version> </dependency> <!-- Jackson可以轻松的将Java对象转换成json对象和xml文档,同样也可以将json、xml转换成Java对象--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jacksonVersion}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>${jacksonVersion}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jacksonVersion}</version> </dependency> <!-- log4j配置, 视情况添加--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4jVersion}</version> </dependency> <!--文件 上传--> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>${fileuploadVersion}</version> </dependency> <!-- lombok插件导包--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>${lombokVersion}</version> <scope>provided</scope> </dependency> </dependencies> </project>
4.配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <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> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 此处指向的的是SpringMVC的配置文件 --> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <!--配置容器在启动的时候就加载这个servlet并实例化--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 字符集过滤 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-hibernate.xml</param-value> </context-param> </web-app>
5.springMVC配置
<mvc:annotation-driven /> <context:component-scan base-package="com.zhiyou100" /> <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <!-- 前缀 --> <property name="prefix" value="view/" /> <!-- 后缀 --> <property name="suffix" value=".jsp" /> </bean> <!--这里是对静态资源的映射 --> <mvc:resources mapping="/js/**" location="/resources/js/" /> <mvc:resources mapping="/css/**" location="/resources/css/" /> <mvc:resources mapping="/img/**" location="/resources/img/" /> </beans> ———————————————— 版权声明:本文为CSDN博主「落红无情物」的原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接及本声明。 原文链接:https://blog.csdn.net/zhang1278851469/article/details/88594164<mvc:annotation-driven /> <context:component-scan base-package="com.zhiyou100" /> <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <!-- 前缀 --> <property name="prefix" value="view/" /> <!-- 后缀 --> <property name="suffix" value=".jsp" /> </bean> <!--这里是对静态资源的映射 --> <mvc:resources mapping="/js/**" location="/resources/js/" /> <mvc:resources mapping="/css/**" location="/resources/css/" /> <mvc:resources mapping="/img/**" location="/resources/img/" /> </beans>
需要修改一下你自己的包名
6.配置spring-hibernate:文件名称:spring_hibernate.xml
<?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <!--********************************************配置Spring***************************************--> <!-- 自动扫描 --> <context:component-scan base-package="com.zy"> <!-- 扫描时跳过 @Controller 注解的JAVA类(控制器) --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!--********************************************配置hibernate********************************************--> <!--扫描配置文件(这里指向的是之前配置的那个config.properties)--> <context:property-placeholder location="classpath:/db.properties" /> <!--配置数据源--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="${jdbc.driver}" /> <!--数据库连接驱动--> <property name="jdbcUrl" value="${jdbc.url}" /> <!--数据库地址--> <property name="user" value="${jdbc.username}" /> <!--用户名--> <property name="password" value="${jdbc.password}" /> <!--密码--> <property name="maxPoolSize" value="40" /> <!--最大连接数--> <property name="minPoolSize" value="1" /> <!--最小连接数--> <property name="initialPoolSize" value="10" /> <!--初始化连接池内的数据库连接--> <property name="maxIdleTime" value="20" /> <!--最大空闲时间--> </bean> <!--配置session工厂--> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="packagesToScan" value="com.zy.pojo" /> <property name="hibernateProperties"> <props> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <!--hibernate根据实体自动生成数据库表--> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <!--指定数据库方言--> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <!--在控制台显示执行的数据库操作语句--> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <!--在控制台显示执行的数据哭操作语句(格式)--> </props> </property> </bean> <!-- 事物管理器配置 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>
注意:里面需要修改包名,在session工厂,还有在spring自动扫描:
7.创建db.property文件:
#database connection config jdbc.driver = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql:///ssm?useUnicode=true&characterEncoding=utf-8 jdbc.username = root jdbc.password = 123456 #hibernate config hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.show_sql = true hibernate.format_sql = true hibernate.hbm2ddl.auto = update
注意:需要修改数据库密码,名称
8.日志配置log4j.properties
### direct log messages to stdout ### log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.err log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n ### direct messages to file mylog.log ### log4j.appender.file=org.apache.log4j.FileAppender log4j.appender.file.File=c:\mylog.log log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n ### set log levels - for more verbose logging change 'info' to 'debug' ### log4j.rootLogger=DEBUG, stdout
9.开始建包建层
9.1先建View层一个展示页面:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <center> <h2 style="color: #ff261a;">this is my test page!</h2> </center> </body> </html>
9.2 建Controller层
package com.zy.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller public class UserController { }
9.3 dao层和pojo实体类层
9.3.1 dao层
package com.zy.dao; public interface UserDao { }
9.3.2 实体类
package com.zy.pojo; public class User { }
9.4 Service层和实现类
9.4.1service层
package com.zy.service; public interface UserService { }
9.4.2 实现类,实现UserService
package com.zy.service.imp; import org.springframework.stereotype.Service; import com.zy.service.UserService; @Service public class UserServiceImp implements UserService{ }
