springMVC环境配置

springMVC环境主要需要spring的Core Libraries和Web Libraries，使用myeclipse可以直接添加这两个包。注意：使用官方的lib时需要另外自己加入com.springsource.org.apache.commons.logging-1.1.1.jar，不然会报错。

Demo.java

package com.demo;

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

@Controller
@RequestMapping("/hello")
public class Demo {
    @RequestMapping("/one")
public String hello(){
    return "hello";
}
}

 

主要是这三个配置文件的编写，然后将jsp文件放在对应的文件夹。最后访问路径是：http://服务器地址：端口/项目名/类的RequestMapping/方法的RequestMapping
