1天搞定SpringBoot+Vue全栈开发 (2)RESTful API与Swagger

package com.example.helloworld.controller;
import com.example.helloworld.entity.User;
import org.springframework.web.bind.annotation.*;
 
@RestController
public class UserController {
    @GetMapping("/user/{id}")
    public String getUserById(@PathVariable int id) { //@PathVariable 注解配合 @GetMapping("/user/{id}") 中的{id}可以在请求路径中传递参数值并获取到参数值
        System.out.println(id);
        return "根据id获取用户信息";
    }
 
    @PostMapping("/user")
    public String save(User user) {
        return "添加用户";
    }
 
    @PutMapping("/user")
    public String update(User user) {
        return "更新用户";
    }
 
    @DeleteMapping("/user/{id}")
    public String deleteById(@PathVariable int id) {
        System.out.println(id);
        return "根据ID删除用户";
    }
}
