ssm整合（配置文件）

ssm整合

1、配置监听器

在ssm框架中需要springIOC先去加载service层和mapper层的数据，后加载SpringMVCIOC容器管理下的controller层才能用，所以用监听去先实现配置SPringIOC容器的需要

注意：为什么不用过滤器？

答：因为在项目中监听器只执行一次，而过滤器可能会执行多次

  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
  listener>
  
  <context-param>
  	<param-name>contextConfigLocationparam-name>
    <param-value>classpath:spring.xmlparam-value>
  context-param>

2、配置spring配置文件

 
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:util="http://www.springframework.org/schema/util"
	xmlns:p="http://www.springframework.org/schema/p"
	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-4.1.xsd
     http://www.springframework.org/schema/context
     http://www.springframework.org/schema/context/spring-context.xsd 
     http://www.springframework.org/schema/util
     http://www.springframework.org/schema/util/spring-util-4.1.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">

	
	 
	  
	  
	  <context:component-scan base-package="controller,mapper,service" >
	  	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	  context:component-scan>
	  
	  <aop:aspectj-autoproxy>aop:aspectj-autoproxy>
	  
	  
	
	<context:property-placeholder location="classpath:Sql.properties"/>
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
		<property name="driverClassName" value="${Sql.driver}">property>
		<property name="url" value="${Sql.url}">property>
		<property name="username" value="${Sql.username}">property>
		<property name="password" value="${Sql.password}">property>
	bean>
	<bean class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource">property>
	bean>
	
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource">property>
	bean>
	
	<tx:annotation-driven transaction-manager="transactionManager"/>
	
	 
	
    
    
	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:mybtis-config.xml">property>
		<property name="dataSource" ref="dataSource">property>
	bean>
	
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="mapper">property>
	bean>
beans>

3、配置SpringMVC配置文件

 
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:util="http://www.springframework.org/schema/util"
	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: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.xsd 
     http://www.springframework.org/schema/util
     http://www.springframework.org/schema/util/spring-util-4.1.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
     http://www.springframework.org/schema/mvc 
     http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	 <context:component-scan base-package="controller">context:component-scan>
	 
	 
	<bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
    	<property name="order" value="1"/>
    	<property name="characterEncoding" value="UTF-8"/>
    	<property name="templateEngine">
        	<bean class="org.thymeleaf.spring5.SpringTemplateEngine">
            	<property name="templateResolver">
                	<bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">   
                    	
                    	<property name="prefix" value="/WEB-INF/templates/"/>    
                    	
                    	<property name="suffix" value=".html"/>
                    	<property name="templateMode" value="HTML5"/>
                    	<property name="characterEncoding" value="UTF-8" />
                	bean>
            	property>
        	bean>
    	property>
	bean>
	
	
	<mvc:default-servlet-handler/>
	
	<mvc:annotation-driven>mvc:annotation-driven>	
	
	<mvc:view-controller path="/" view-name="index">mvc:view-controller>
	
	
	 
	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">bean>
beans>

4、配置mybatis配置文件

DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	
	<settings>
		
		<setting name="mapUnderscoreToCamelCase" value="true"/>
		
		<setting name="lazyLoadingEnabled" value="true"/>
	settings>
	
	
	<typeAliases>
	
	
	
		<package name="pojo"/>
	typeAliases>
	
	
	
  <mappers>
    
    
    <package name="mapper"/>
  mappers>
configuration>

5、引入依赖
