SSM整合

整合环境 : myeclipse

1. 导入jar包:

ssm.jar

2. 创建springmvc配置文件

在src目录下创建sqlMapConfig.xml文件

<?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>
    <typeAliases>
        <package name="com.springmvc.entity" />
    </typeAliases>
</configuration>

3. 创建spring配置文件

在src目录下创建applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">

</beans>

4. 配置MyBatis

在src下创建数据库需要的db.properties文件 . 在applicationContext.xml文件中配置Mybatis

<context:property-placeholder location="classpath:db.properties"/>

<!-- 数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="${jdbc.driver}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
    <property name="maxActive" value="10" />
    <property name="maxIdle" value="5" />
</bean>

<!-- Mybatis的工厂 -->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <!-- 核心配置文件的位置 -->
    <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
</bean>

<!-- Mapper动态代理开发   扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!-- 基本包 -->
    <property name="basePackage" value="com.springmvc.dao"/>
</bean>

5. 配置springmvc

在src下创建springmvc.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:p="http://www.springframework.org/schema/p"
    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-4.0.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
        
    <!-- 扫描@Controler @Service -->
    <context:component-scan base-package="com.springmvc" />
     <!-- 注解驱动 -->
    <mvc:annotation-driven conversion-service="conversionServiceFactoryBean" />
    <!-- 视图解释器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

6.配置web.xml文件

配置spring监听器

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  
  <!-- Spring监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

配置springmvc前端控制器

    <!-- 前端控制器 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 默认找 /WEB-INF/[servlet的名称]-servlet.xml -->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springmvc.xml</param-value>
    </init-param>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <!-- 
        1. /*  拦截所有   jsp  js png .css  真的全拦截   建议不使用
        2. *.action *.do 拦截以do action 结尾的请求     肯定能使用   ERP  
        3. /  拦截所有 （不包括jsp) (包含.js .png.css)  强烈建议使用     前台 面向消费者  www.jd.com/search   /对静态资源放行
     -->
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>
