eclipse中使用maven创建springmvc项目-526互联

第一步，eclipse---File---New---Maven Project

第二步，如图直接Next

第三步，如图直接Next

第四步，Group Id一般写公司域名的反转，Artifact Id写项目名称，然后点击Finish

第五步，创建好项目后，开始修改配置文件

<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">

    </dependency>
  </dependencies>
  <build>
    <finalName>xiangmu2</finalName>
  </build>
</project>

以上是pom.xml文件

    <listener> 
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
    
</web-app>

以上是web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="

    <context:component-scan base-package="com.gongsi.xiangmu2"></context:component-scan>
    <!-- 视图页面配置 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--前缀：视图文件的路径-->
        <property name="prefix" value="/WEB-INF/view/"/>
        <!--后缀：视图文件的扩展名-->
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

以上是在/src/main/resources目录下创建的spring-mvc.xml文件

package com.gongsi.xiangmu2;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {
     
    @RequestMapping("/hello")
    public String showMessage(HttpServletRequest request, HttpServletResponse response) {
        request.setAttribute("name", "xiaoHong");
        return "hello";
    }
}

以上是在src/main/java包下创建的HelloController文件
