JavaWeb博客系统后端-功能需求

JavaWeb博客系统后端-项目创建

JavaWeb博客系统后端-封装返回结果

前面我们编写了ResponseResult，作为我们返回的类，里面可以封装请求是否成功，状态码和数据信息

一般来说，我们为了方便使用，快速创建，我们会编写几个快速创建的方法。

比如说：

• SUCCESS() 成功
• FAILED() 失败
• PERMISSION_DENINE() 权限不够
• UN_LOGIN() 未登录
• PARAMS_ILL() 参数错误

通过枚举表示各种情况

package net.sunofbeaches.response;

public interface IResponseState{

    String getMessage();

    boolean isSuccess();

    int getCode();
}

定义一个接口供外面使用

package net.sunofbeaches.response;

public enum ResponseState implements ICommentResult {
    SUCCESS(10000, true, "操作成功"),
    FAILED(20000, false, "操作失败"),
    PARAMS_ILL(30000, false, "参数错误"),
    PERMISSION_DENIED(40000, false, "权限不够"),
    NOT_LOGIN(50000, false, "账号未登录")，
    LOGIN_SUCCESS(60000,true, "登录成功");


    int code;
    boolean isSuccess;
    String message;

    ResponseState(int code, boolean isSuccess, String message) {
        this.code = code;
        this.isSuccess = isSuccess;
        this.message = message;
    }

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

    @Override
    public boolean isSuccess() {
        return isSuccess;
    }

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

}

重构ResponseResult

package net.sunofbeaches.response;

public class ResponseResult {

    public ResponseResult(ICommentResult commentResult) {
        this.message = commentResult.getMessage();
        this.success = commentResult.isSuccess();
        this.code = commentResult.getCode();
    }

    public static ResponseResult SUCCESS() {
        return new ResponseResult(CommentResponse.SUCCESS);
    }

    public static ResponseResult SUCCESS(String message) {
        ResponseResult success = SUCCESS();
        success.setMessage(message);
        return success;
    }

    public static ResponseResult FAILED() {
        return new ResponseResult(CommentResponse.FAILED);
    }

    public static ResponseResult FAILED(String message) {
        ResponseResult failed = FAILED();
        failed.setMessage(message);
        return failed;
    }

    private String message;
    private boolean success;
    private int code;
    private Object data;

    public String getMessage() {
        return message;
    }

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

    public boolean isSuccess() {
        return success;
    }

    public void setSuccess(boolean success) {
        this.success = success;
    }

    public int getCode() {
        return code;
    }

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

    public Object getData() {
        return data;
    }

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

如果后面有需要，再添加即可！按套路出牌就好！
