springboot-controller的使用
获取url中的数据:
@RestController
public class HelloController {
@RequestMapping(value="/say/{id}", method = RequestMethod.GET)
public String say(@PathVariable("id") Integer id){
return "id:"+id;
}
}
在输入url地址:http://127.0.0.1:8081/girl/say/23
显示:id:23
用传统的方式http://127.0.0.1:8081/girl/say?id=11
获取到其中的参数:
@RestController
public class HelloController {
@RequestMapping(value="/say", method = RequestMethod.GET)
//@GetMapping(value="/say") 简化的写法
public String say(@RequestParam("id") Integer myid){
return "id:"+myid;
}
}
