+
+## 作业
+
+步骤;
+
+1.pom.xml，将没有的东西复原，如java，test。。。
+
+```xml
+<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
+  <modelVersion>4.0.0</modelVersion>
+  <groupId>com.xlu</groupId>
+  <artifactId>ssmvc</artifactId>
+  <packaging>war</packaging>
+  <version>1.0-SNAPSHOT</version>
+
+  <dependencies>
+    <dependency>
+      <groupId>javax.servlet</groupId>
+      <artifactId>javax.servlet-api</artifactId>
+      <version>3.1.0</version>
+      <scope>provided</scope>
+    </dependency>
+
+    <dependency>
+      <groupId>org.springframework</groupId>
+      <artifactId>spring-webmvc</artifactId>
+      <version>5.2.25.RELEASE</version>

+        </configuration>
+      </plugin>
+
+    </plugins>
+  </build>
+</project>
+
+```
+
+2.创建com.xlu.config.SpringMvcConfig
+
+```java
+package com.xlu.config;
+
+import org.springframework.context.annotation.ComponentScan;
+import org.springframework.context.annotation.Configuration;
+
+@Configuration
+@ComponentScan("com.xlu")
+public class SpringMvcConfig {
+}
+```
+
+3.com.xlu.config.WeblnitConfig
+
+```java
+package com.xlu.config;
+
+import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
+
+public class WeblnitConfig extends AbstractAnnotationConfigDispatcherServletInitializer {
+
+
+    protected Class<?>[] getRootConfigClasses() {
+        return new Class[0];//加载spring的核心配置文件
+    }
+
+    protected Class<?>[] getServletConfigClasses() {
+        //加载springmvc的核心配置文件
+        return new Class[]{SpringMvcConfig.class};
+    }
+
+    protected String[] getServletMappings() {
+        //设置从/开始的路径，都归tomcat管理
+        return new String[]{"/"};
+    }
+}
+```
+
+4.com.xlu.controller.UserController
+
+```java
+package com.xlu.controller;
+
+import org.springframework.stereotype.Controller;
+import org.springframework.web.bind.annotation.RequestMapping;
+import org.springframework.web.bind.annotation.ResponseBody;
+
+import javax.xml.ws.RequestWrapper;
+import java.security.PublicKey;
+
+@Controller
+public class UserController {
+
+
+    @RequestMapping("/save")
+    @ResponseBody
+    public String userSave(){
+
+        return "ok";//http://localhost:88/save网址，查看是否出现OK
+
+    }
+
+    @RequestMapping("/book")
+    @ResponseBody
+    public String book(){
+        return "book is ok!";//http://localhost:88/book网址，查看是否有东西
+    }
+
+
+    @RequestMapping("/hello")
+    @ResponseBody
+    public String hello(){
+
+        System.out.println(666);
+        return "666";//http://localhost:88/hello网址，查看是否有东西
+
+    }
+
+//    @RequestMapping("/shouYe")
+//    public String shouYe(){
+//
+//        return "index.jsp";//http://localhost:88/shouYe网址，跳转网页出现 helloword
+//    }
+
+    @RequestMapping("/shouYe")
+    @ResponseBody
+    public String shouYe(){
+
+        return "index.jsp";//http://localhost:88/shouYe网址，出现index.jsp
+    }
+
+
+}
+```
