使用maven纯注解集成ssm

配置springMVC框架

第一步：导入包依赖

<!--配置springMVC-->
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>javax.servlet.jsp-api</artifactId>
            <version>2.3.3</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>5.1.7.RELEASE</version>
        </dependency>

依赖包

第二部：编写web.xml--设置前端控制器

<servlet>
     <servlet-name>DispatcherServlet</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <init-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>org.kong.config</param-value>
     </init-param>    
     <init-param>
            <param-name>contextClass</param-name>
            <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </init-param>
        <load-on-startup>1</load-on-startup>
 </servlet>
<servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>     

web.xml

第三部：编写springMVC配置类

 1 package org.kong.config;
 2 import org.springframework.context.annotation.ComponentScan;
 3 import org.springframework.context.annotation.Configuration;
 4 import org.springframework.web.servlet.config.annotation.EnableWebMvc;
 5 
 6 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
 7 
 8 @SuppressWarnings("deprecation")
 9 @Configuration
10 //开启包扫描注解
11 @ComponentScan(basePackages="org.kong")
12 //开启mvc注解驱动
13 @EnableWebMvc
14 public class MVCconfig extends WebMvcConfigurerAdapter {
15 
16 }mvc

mvc配置类

第四部：编写controller组件类

 1 package org.kong.controller;
 2 
 3 import org.springframework.stereotype.Controller;
 4 import org.springframework.web.bind.annotation.RequestMapping;
 5 
 6 @Controller
 7 public class Test {
 8     @RequestMapping("/hellow")
 9     public String hello() {
10         System.out.println("hellow");
11         return null;
12         
13     }
