SpringMVC Restful风格

在controller的类上添加@RestController注解

package com.xiaoya.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@Controller
@RestController
public class TestController {
    @RequestMapping("/hello/{name}")
    @ResponseBody
    public String hello(@PathVariable String name){
        return "hello "+name;
    }
}

在方法的参数前面标上@PathVariable注解，然后路径中使用{name}就可以解析变量

启动tomcat，访问http://localhost:8080/springmvc1_war_exploded/hello/2
