本文详细介绍了Spring框架的整合步骤，包括导入相关jar包、配置IOC容器、设置SpringMVC前端控制器、配置MyBatis及web.xml等核心环节。

复习复习复习，长时间写代码，框架都快不会搭了

1、导入整合用的相关jar包

如果出现以下异常：请检查Spring-jdbc 和 aspectjweaver 的jar包是否导入
在这里插入图片描述

2、接下来是Spring的ioc容器

<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:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	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-4.3.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
		<!--注解扫描 扫描除了控制器之外的业务层，持久层等 -->
		<context:component-scan base-package="com.du" use-default-filters="false">
			<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
		</context:component-scan>
		<!-- 载入数据库配置 文件 -->
		<context:property-placeholder location="classpath:config/db.properties"/>
		<!-- 配置数据源  -->
		<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
			<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
			<property name="url" value="jdbc:mysql://localhost:3306/mofujinfu"></property>
			<property name="username" value="root"></property>
			<property name="password" value="root"></property>
		</bean>
		<!-- 配置SQLSession工厂 -->
		<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
			<property name="dataSource" ref="dataSource"></property>
			<!-- 整合mybatis-->
			<property name="configLocation" value="classpath:config/mybatis-spring.xml"></property>
			<!-- mybatis Mapper映射文件 -->
			<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
		</bean>
		<!-- 配置mybatis Mapper文件扫描器 -->
		<bean  class="org.mybatis.spring.mapper.MapperScannerConfigurer">
			<property name="basePackage" value="com.du.dao"></property>
		</bean>
		<!-- 配置数据源事物控制 -->
		<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
			<property name="dataSource" ref="dataSource"></property>
		</bean>
	<!--开启基于注解的事务，使用xml配置形式的事务（必要主要的都是使用配置式）  -->
	<aop:config>
		<!-- 切入点表达式 -->
		<aop:pointcut expression="execution(* com.du.service..*(..))" id="txPoint"/>
		<!-- 配置事务增强 -->
		<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
	</aop:config>
	
	<!--配置事务增强，事务如何切入  -->
	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<!-- 所有方法都是事务方法 -->
			<tx:method name="*"/>
			<!--以get开始的所有方法  -->
			<tx:method name="get*" read-only="true"/>
		</tx:attributes>
	</tx:advice>
</beans>

3、配置SpringMVC前端控制器

<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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		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-4.3.xsd">
	<!-- 配置控制层扫描 ，此处的Controller是接口-->
	<context:component-scan base-package="com.du">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
	<!-- 开启SpringMVC高级功能 -->
	<mvc:annotation-driven/>
	<!-- 解析SpringMVC无法解析的 -->
	<mvc:default-servlet-handler/>
	<!-- 解析视图层,这里主要是解析jsp,当然也可以整合Thymeleaf框架，相对jsp来说，Thymeleaf效率更高效-->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="WEB-INF/views"></property>
			<property name="suffix" value=".jsp"></property>
	</bean>
</beans>

4、配置mybaitis文件

<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!--开启驼峰命名-->
	<settings>
		<setting name="mapUnderscoreToCamelCase" value="true"/>
	</settings>
	<!--实体类别名-->
	<typeAliases>
		<package name="com.du.bean"/>
	</typeAliases>
</configuration>

5、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" 
		 id="WebApp_ID" version="2.5">
	<!-- 启动Spring IOC容器 -->
	<!-- needed for ContextLoaderListener -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext.xml</param-value>
	</context-param>
	
	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- 启动前端控制器 -->
	<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/dispatcherServlet.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>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- 字符编码过滤器 -->
	<filter>
		<filter-name>encoding</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>forceRequestEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
		<init-param>
			<param-name>forceResponseEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encoding</filter-name>
		<servlet-name>springDispatcherServlet</servlet-name>
	</filter-mapping>
	<!-- 此处开启REST请求风格 -->
	<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>
	<!-- 此处 过滤是作为获取put请求的表单值-->
	<filter>
		<filter-name>httpPutFormContentFilter</filter-name>
		<filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
	</filter>
	
	<filter-mapping>
		<filter-name>httpPutFormContentFilter</filter-name>
		<servlet-name>springDispatcherServlet</servlet-name>
	</filter-mapping>
</web-app>

开启服务器已完美通过，写个控制层测试一下

package com.du.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
/**
 * 
 * @author BlueSky
 * SpringMVC会扫描含有@Controller注解的类，SpringIOC容器会排除含有@Controller注解的类
 */
@Controller
public class IndexController {
	
	@RequestMapping("/index")
	public String index(){
		//SpringMVC默认是转发而不是重定向，如果需要重定向，则return "redirect:index";
		//此处跳转到WEB-INF/VIEWS/index.html
		return "index";
	}
	@RequestMapping("/json")
	@ResponseBody //如果需要将Object转换为json,需要加入@ResponseBody
	public Object json(){
		Map map = new HashMap<>();
		map.put("name", "张三");
		map.put("age", 17);
		return map;
	}
}

结果，完美
