Springboot接受参数的几种方式

1、get方式？传参：

http://localhost:8089/show/?id=123
    @GetMapping("/show")
    public ResponseEntity show(String id) {
        return ResponseEntity.ok(id);
    }

2、get方式路径传参

```java
http://localhost:8089/show/123
    @GetMapping("/show/{id}")
    public ResponseEntity show(@PathVariable(name = "id") String id) {
        return ResponseEntity.ok(id);
    }

3、javabeen接收参数

//实体类
import lombok.Data;
import java.io.Serializable;
@Data
public class UserDTO implements Serializable {
    private String idno;
    private String name;
}
--------------------------------------------------------------
    @PostMapping("/postShow")
    public ResponseEntity postShow(@RequestBody User user) {
        logger.info("返回参数："+ResponseEntity.ok(user.getIdno()));
        return ResponseEntity.ok(Cfcactive.getIdno());
    }
