package com.yiba.wifi.news.controller;

import com.yiba.wifi.news.bean.domain.User;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.*; @RestController
@RequestMapping("api")
public class UserController { Logger logger = LoggerFactory.getLogger(this.getClass()); /**
* 查询 id 数据
* @return
*/
@GetMapping("find")
public User findOne() { //查询用户逻辑.....
return new User();
} }

2、带参数

请求api

http://localhost:8083/api/find?name=zhaoyanjun

package com.yiba.wifi.news.controller;

import com.yiba.wifi.news.bean.domain.User;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.*; @RestController
@RequestMapping("api")
public class UserController { Logger logger = LoggerFactory.getLogger(this.getClass()); /**
* 查询 id 数据
* 当 name 为 null 的时候,用默认值 yanjun 代替
* @return
*/
@GetMapping("find")
public User findOne(@RequestParam(value = "name", defaultValue = "yanjun") String name) { //查询用户逻辑.....
logger.info("name:" + name);
return new User();
} }

3、RESTful API

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.*; @RestController
@RequestMapping("api")
public class UserController { Logger logger = LoggerFactory.getLogger(this.getClass()); /**
* 查询 id 数据
*
* @param id
* @return
*/
@GetMapping("find/{id}")
public User findOne(@PathVariable("id") Integer id) {
logger.info("id:" + id); //查询用户逻辑.....
return new User();
} }
