springboot请求响应封装

一 响应实体：

@ApiModel("通用返回对象")
@Getter
public class ControllerMessage implements Serializable {
    @ApiModelProperty(value = "返回码", notes = "0代表成功")
    private final int code;
    @ApiModelProperty("描述信息")
    private final String message;
    @ApiModelProperty("数据")
    private final T data;
    
    private static final int SUCCESS_CODE = 0;

    private ControllerMessage(int code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    public static  ControllerMessage ofSuccess(String message) {
        return of(SUCCESS_CODE, message, null);
    }

    public static  ControllerMessage ofSuccess(String message, T data) {
        return of(SUCCESS_CODE, message, data);
    }

    private static  ControllerMessage of(int code, String message, T data) {
        return new ControllerMessage<>(code, message, data);
    }

    public static  ControllerMessage ofError(IControllerErrorBaseEnum controllerErrorBaseEnum) {
        return of(controllerErrorBaseEnum.getCode(), controllerErrorBaseEnum.getMessage(), null);
    }
}

二 错误枚举基类接口

public interface IControllerErrorBaseEnum {
    int getCode();
    String getMessage();
}
