一、创建返回状态码类
public interface ResultCode {
public static Integer SUCCESS = 20000;
public static Integer ERROR = 20001;
}
二、创建统一结果类
@Data
public class R {
@ApiModelProperty(value = "是否成功")
private Boolean success;
@ApiModelProperty(value = "返回码")
private Integer code;
@ApiModelProperty(value = "返回消息")
private String message;
@ApiModelProperty(value = "返回数据")
private Map<String, Object> data = new HashMap<String, Object>();
private R(){}
public static R ok(){
R r = new R();
r.setSuccess(true);
r.setCode(ResultCode.SUCCESS);
r.setMessage("成功");
return r;
}
public static R error(){
R r = new R();
r.setSuccess(false);
r.setCode(ResultCode.ERROR);
r.setMessage("失败");
return r;
}
public R success(Boolean success){
this.setSuccess(success);
return this;
}
public R message(String message){
this.setMessage(message);
return this;
}
public R code(Integer code){
this.setCode(code);
return this;
}
public R data(String key, Object value){
this.data.put(key, value);
return this;
}
public R data(Map<String, Object> map){
this.setData(map);
return this;
}
}
三、
一般将该工具类置于公共模块中，只要相应服务的pom中引入了公共模块的依赖，则就可以在Controller的方法中用链式编程方式返回相应的数据及状态码给前端
例如：
前端效果：
{
"success": true,
"code": 20000,
"message": "成功",
"data": {}
}
