• IDEA搭建SpringMVC简单接口框架(Maven项目)


             源码路径:https://github.com/winn-hu/interface 

    1, 新建项目,选择Maven,如图一次选择,最后点击Next

    2, 输入GroupId和ArtifactId,点击Next

    3,根据需要选择自定义maven配置,点击Next。(①可以直接跳过)

     

    4,根据需要修改项目名称(一般不用修改),点击Finish。(①可以直接跳过)

    5,当控制台输出BUILD SUCCESS后,项目创建成功。

    6,修改pom.xml,添加依赖包

    <dependencies>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.5.RELEASE</version>
      </dependency>
    </dependencies>
    

      

    7,创建index.jsp【用于启动项目项目时,默认展示页面】
     
    8,创建接口类(Controller)

    package com.blueStarWei.controller;
    
    
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    
    @RestController
    @RequestMapping("/hello")
    public class HelloWorld {
    
    
        @RequestMapping("/say/{name}")
        public String say(@PathVariable String name){
            return "Hello World, "+name;
        }
    }
    

    9,配置applicationContext.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"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
                               http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    
      <context:component-scan base-package="com.blueStarWei.*" />
    
    
      <bean id="viewResolver"
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp"/>
      </bean>
    
    
    </beans>
    

    10,配置web.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.4"
             xmlns="http://java.sun.com/xml/ns/j2ee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    
    
      <!--  DispatcherServlet默认使用WebApplicationContext作为上下文,
          Spring默认配置文件为“/WEB-INF/[servlet名字]-servlet.xml”
       -->
      <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    
    </web-app>
    

    11,创建springmvc-servlet.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: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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
    
        <context:component-scan base-package="com.blueStarWei.*" />
        <mvc:annotation-driven/>
    </beans>
    

    12,  配置tomcat.(⑦和⑧可以跳过)

     

     

     

     

    13,项目配置完成,可以启动服务器,(使用浏览器活postman等)进行访问。
