spring boot 之 接口参数校验

引入pom依赖

<!--参数校验-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

统一返回结果封装

import lombok.Data;

import java.io.Serializable;

@Data
public class Result<T> implements Serializable {
   

    private Integer code;

    private String msg;

    private T data;

}

import lombok.Getter;

@Getter
public enum ResultEnum {
   

    SUCCESS(200, "请求成功"),

    FAIL(500, "请求失败");

    private final Integer code;

    private final String msg;

    ResultEnum(Integer code, String msg) {
   
        this.code = code;
        this.msg = msg;
    }

}

public class AjaxResult {
   
    
    public static <T> Result<T> success() {
   
        return common(ResultEnum.SUCCESS.getCode(), ResultEnum.SUCCESS.getMsg(), null);
    }

    public static <T> Result<T> success(T data) {
   
        return common(ResultEnum.SUCCESS.getCode(), ResultEnum.SUCCESS.getMsg(), data);
    }

    public static <T> Result<T> fail() {
   
        return common(ResultEnum.FAIL.getCode(), ResultEnum.FAIL.getMsg(), null);
    }

    public static <T> Result<T> fail(String msg) {
   
        return common(ResultEnum.FAIL.getCode(), msg, null);
    }

    /**
     * 公共响应方法
     */
    private static <T> Result<T> common(Integer code, String msg, T data) {
   
        Result<T> result = new Result<>();
        result.setCode(code);
        result.setMsg(msg);
        result.setData(data);
        return result;
    }
}
