33.公共控制器，统一返回，异常统一处理

1.公共控制器BaseController

package com.haiyeren.controller;

public class BaseController {

}

2.统一返回ResultVo、ResultVo

package com.haiyeren.entity.vo;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

@ApiModel("返回对象")
@Data
public class ResultVo<T> {

    @ApiModelProperty(value = "返回消息", required = true)
    private String message="执行成功";
    @ApiModelProperty(value = "状态码:1正常，401未登录，500服务异常", required = true)
    private Integer status=1;

    @ApiModelProperty(value = "返回数据", required = false)
    private T data;


}

package com.haiyeren.entity.vo;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.List;

@ApiModel("返回列表对象")
@Data
public class PageListVo<T>  {
    @ApiModelProperty(value = "返回消息", required = true)
    private String message="执行成功";
    @ApiModelProperty(value = "状态码:1正常，401未登录，500服务异常", required = true)
    private Integer status=1;
    @ApiModelProperty(value = "列表", required = true)
    private List<T> list;
    @ApiModelProperty(value = "总数", required = true)
    private Long total;


}

3.异常统一处理

package com.haiyeren.config;


import com.haiyeren.entity.vo.ResultVo;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

/**

 */
@RestControllerAdvice(value = {"com.haiyeren"})
public class ApiExceptionHandler {
    private Logger logger = LoggerFactory.getLogger(ApiExceptionHandler.class);


    @ExceptionHandler(Exception.class)
    public ResultVo handleException(Exception e) {
        logger.error(e.getMessage(), e);
        ResultVo resultVo=new ResultVo();

        resultVo.setStatus(500);
        resultVo.setMessage("服务器繁忙，请稍后重试");
        return resultVo;
    }


}
