Spring 动态路径 学习笔记

owo

示例:

@RestController
public class UserController {

    @GetMapping("/user/{id}")
    public String getUserById(@PathVariable int id) {
        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";
    }
}

要获取动态路径的参数需要加 @PathVariable ,否则会获取后面的
