接口统一响应

统一接口响应

定义状态接口

package com.smile.cms.utils.response;

/**
 * 相应的状态接口
 */
public interface IErrorCode {
    /**
     * 返回状态码
     */
    int getCode();

    /**
     * 返回提示信息
     */
    String getMessage();
}

定义枚举类型

package com.smile.cms.utils.response;

public enum ResponseCode implements IErrorCode{
    SUCCESS(200,"成功"),

    ERROR(400,"失败"),

    UNAUTHORIZED(401,"身份验证失败"),

    VALIDATE_FAILED(402,"参数校验异常"),

    FORBIDDEN(403,"无权限访问"),

    NOT_FOUND(404,"路由未找到"),

    METHOD_NOT_ALLOWED (405,"请求方法不支持"),

    HTTP_TOO_MANY_REQUESTS(429,"接口频率限制"),

    HTTP_INTERNAL_SERVER_ERROR(500,"系统错误");

    /**
     * 状态码
     */
    private int code;

    /**
     * 提示消息
     */
    private String message;

    private ResponseCode(int code,String message)
    {
        this.code = code;
        this.message = message;
    }

    @Override
    public int getCode() {
        return code;
    }

    @Override
    public String getMessage() {
        return message;
    }
}

接口响应数据

package com.smile.cms.utils.response;

/**
 * 接口相应
 * @param <T>
 */
public class ApiResponse <T>{
    private int code;

    private String message;

    private T data;

    private ApiResponse() {}

    public ApiResponse(T data,int code,String message)
    {
        this.data = data;

        this.code = code;

        this.message = message;
    }

    public long getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    public static <T> ApiResponse<T> success()
    {
        return new ApiResponse<T>(null,ResponseCode.SUCCESS.getCode(), ResponseCode.SUCCESS.getMessage());
    }

    public static <T> ApiResponse<T> success(String message)
    {
        return new ApiResponse<T>(null,ResponseCode.SUCCESS.getCode(), message);
    }

    public static <T> ApiResponse<T> success(String message,int code)
    {
        return new ApiResponse<T>(null,code, message);
    }

    public static <T> ApiResponse<T> success(String message,int code,T data)
    {
        return new ApiResponse<T>(data,code, message);
    }

    public static <T> ApiResponse<T> error()
    {
        return new ApiResponse<T>(null,ResponseCode.ERROR.getCode(), ResponseCode.SUCCESS.getMessage());
    }

    public static <T> ApiResponse<T> error(String message)
    {
        return new ApiResponse<T>(null,ResponseCode.ERROR.getCode(), message);
    }

    public static <T> ApiResponse<T> error(String message,int code)
    {
        return new ApiResponse<T>(null,code, message);
    }

    public static <T> ApiResponse<T> error(String message,int code,T data)
    {
        return new ApiResponse<T>(data,code, message);
    }
}
