# （二）集成ssm框架 #

上一篇文章中我讲了在idea中创建一个java web的项目，这一篇中我讲一下集成ssm框架

spring、spring MVC、MyBatis

## 第一步 导入jar包 ##

## 第二步 前端控制器配置 web.xml 文件 ##

中间会 爆红 这是因为你还没有配置

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
    
        
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                /WEB-INF/classes/spring/applicationContext-*.xml </param-value>
        </context-param>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
    
        
        <servlet>
            <servlet-name>springmvc_rest</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            
            <init-param>
                <param-name>contextConfigLocation</param-name>
                
                <param-value>classpath:spring/springmvc.xml</param-value>
            </init-param>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc_rest</servlet-name>
            
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
        
        <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>
    
        
        <servlet-mapping>
                <servlet-name>default</servlet-name>
                <url-pattern>*.png</url-pattern>
            </servlet-mapping>
            <servlet-mapping>
                <servlet-name>default</servlet-name>
                <url-pattern>*.css</url-pattern>
            </servlet-mapping>
            <servlet-mapping>
                <servlet-name>default</servlet-name>
                <url-pattern>*.js</url-pattern>
        </servlet-mapping>
    
    
    </web-app>

## 第三步 配置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:context="http://www.springframework.org/schema/context"
           xmlns:aop="http://www.springframework.org/schema/aop"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           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.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        <context:component-scan base-package="com.jiang.controller" />
    
        
        <aop:config proxy-target-class="true"></aop:config>
    
        
        <mvc:resources location="/js/" mapping="/js/**" />
        <mvc:resources location="/img/" mapping="/img/**" />
        <mvc:resources location="/css/" mapping="/css/**" />
    
        <mvc:annotation-driven></mvc:annotation-driven>
    
        
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean>
    
        
        <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            
            <property name="defaultEncoding" value="utf-8"></property>
            
            <property name="maxUploadSize" value="102424400"></property>
        </bean>
        
    </beans>

## 第四步 applicationContext-service.xml ##

## 第五步 编写测试文件 controller ##

package com.jiang.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @RequestMapping("/user")
    @Controller
    public class UserController {
    
        @RequestMapping("/test")
        @ResponseBody
        public Integer test(){
            return 1;
        }
    }

## 六 测试 ##
