**添加依赖的Jar包**

                <type>jar</type>
            </dependency>

**修改web.xml文件**

<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_3_1.xsd"
        version="3.1" metadata-complete="true">
      <display-name>Archetype Created Web Application</display-name>
    </web-app>

**前端控制器 DispatcherServlet**

在web.xml文件中配置前端控制器

<servlet>
            <servlet-name>SSM</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:/spring-mvc.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>SSM</servlet-name>
            
            <url-pattern>/</url-pattern>
        </servlet-mapping>

**创建spring-mvc.xml配置文件**

在src/main/resources目录下创建spring-mvc.xml

![这里写图片描述][SouthEast 2]

**配置注解映射 mvc:annotation-driven**

<mvc:annotation-driven/>

**组件扫描 context:component-scan**

<context:component-scan base-package="com.wishfulcloud.ss"></context:component-scan>

视图解析器

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/views/" />
            <property name="suffix" value=".jsp" />
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        </bean>

**完整的spring-mvc.xml**

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
    
        
        <context:component-scan base-package="com.wishfulcloud.ss"></context:component-scan>
    
        
        <mvc:annotation-driven/>
    
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/views/" />
            <property name="suffix" value=".jsp" />
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        </bean>
    
    </beans>

**支持返回的对象转换为Json**
