在 common 模块中创建 common_utils
子模块
在 top.it6666.common_utils.utils
下创建一个接口为 状态码
新建 ResultCode
内容如下
/**
* @author BNTang
*/
public interface ResultCode {
/**
* 成功状态码
*/
Integer SUCCESS = 20000;
/**
* 失败的状态码
*/
Integer ERROR = 20001;
}
紧接着在 top.it6666.common_utils.utils
下创建一个统一返回结果的类 ResponseResult.java
/**
* @author BNTang
*/
public class ResponseResult {
private ResponseResult() {
}
(value = "是否成功")
private Boolean success;
(value = "状态码")
private Integer code;
(value = "返回消息")
private String message;
(value = "返回的数据")
private Map<String, Object> data = new HashMap<>();
/**
* 提供工具方法
*/
public static ResponseResult ok() {
ResponseResult responseResult = new ResponseResult();
responseResult.setSuccess(true);
responseResult.setCode(ResultCode.SUCCESS);
responseResult.setMessage("成功");
return responseResult;
}
public static ResponseResult error() {
ResponseResult responseResult = new ResponseResult();
responseResult.setSuccess(false);
responseResult.setCode(ResultCode.ERROR);
responseResult.setMessage("失败");
return responseResult;
}
public ResponseResult success(Boolean success) {
this.setSuccess(success);
return this;
}
public ResponseResult message(String message) {
this.setMessage(message);
return this;
}
public ResponseResult code(Integer code) {
this.setCode(code);
return this;
}
public ResponseResult data(String key, Object value) {
this.data.put(key, value);
return this;
}
public ResponseResult data(Map<String, Object> map) {
this.setData(map);
return this;
}
}
