基于Eclipse的SSM框架配置文件

说明：该项目是基于Eclipse的SSM框架

1、pom.xml文件：

2、 在src / main / resources下，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

	 <!-- 不能扫描控制器 -->   
	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> 
	</context:component-scan> 

	
	<!-- 配置和mybatis的整合 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	  <!-- 指定mybatis 全局配置文件的位置 -->
	  <property name="configLocation" value="classpath:mybatis-config.xml"></property>
	  <property name="dataSource" ref="pooledDataSource"></property>
	  <!-- 指定mybatis  mapper文件的位置 -->

	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		 <!-- 扫描所有的dao接口 -->

	<!-- 事务控制的配置 -->
	<!-- 用的是aop -->

	<!-- transactionManager  是事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
      <!-- 控制数据源 -->

    </bean>
    <aop:config>
    <!-- 切入点表达式   只要满足这个表达式的  都是切入点  切入点是可以织入事务的-->

        </tx:attributes>
     </tx:advice>

</beans>

3、 在src / main / resources下，dbconfig.properties.xml

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm-crud
jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.user=root
jdbc.password=root

4、 在src / main / resources下，mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
 <configuration>
 
 </configuration>

5、 在WebContent / WEB-INF下，WEB-INF / dispatcherServlet-servlet.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"

	<context:component-scan base-package="com.zhiyou" use-default-filters="false">
	<!-- 因为是spring mvc 只需要扫描控制器 -->
	  <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	<!-- 配置视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	  <property name="prefix" value="/WEB-INF/views/"></property>
	  <property name="suffix" value=".jsp"></property>
	</bean>
	
<!-- 两个标准配置 -->
  <!-- 将springmvc 不能处理的请求交给tomcat  例如静态资源 -->
  <!-- 静态资源：js文件  css样式  图片... -->
  <!-- 静态资源是不需要经过DispatcherServlet的  -->
  <!-- 此注解的作用就是把这些静态资源交给tomcat处理 -->
  <mvc:default-servlet-handler/>
   <!-- 支持spring mvc 更高级的功能  例如 jsr303校验  映射动态请求  -->
   <mvc:annotation-driven/>

</beans>

6、 在WebContent / WEB-INF下， 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" id="WebApp_ID" version="2.5">

<!-- 配置spring容器 -->

<!-- needed for ContextLoaderListener -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<!-- 指定spring的配置文件的位置 -->
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

	<!-- Bootstraps the root web application context before servlet initialization -->
	<!-- ContextLoaderListener 负责加载spring的容器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	
	<!-- 配置springmvc的 前端控制器 -->
	
	<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- <init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param> -->
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<!-- 拦截所有请求 -->
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- 编码过滤器 -->
	<!-- <filter>
	  <filter-name>characterEncodingFilter</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>
	</filter>

	<filter-mapping>
	  <filter-name>characterEncodingFilter</filter-name>
	  <url-pattern>/*</url-pattern>
	</filter-mapping> -->
	
	<!-- rest风格  编程 不是必须的-->
	<!-- <filter>
		<filter-name>hiddenHttpMethodFilter</filter-name>
		  <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
		</filter>
	<filter-mapping>
		<filter-name>hiddenHttpMethodFilter</filter-name>
		  <url-pattern>/*</url-pattern>
	</filter-mapping> -->
	
	
	
	
</web-app>

最后，页面的问题：

index.jsp 放到WebContent下

<%@ 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>
hello  ssm
<br/>
<a href="hello">hello</a>
</body>
</html>

WebContent / WEB-INF / views下放需要跳转的jsp页面

例如：success.jsp

<%@ 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>
成功页面  success.jsp
</body>
</html>
