一、封装统一返回结果类

import com.jiusen.exercise.enums.errorenum;
import com.jiusen.exercise.exception.businessexception;
import lombok.getter;
import lombok.setter;
 
/**
 * @author: lawson
 * @date: 2021/5/11
 * @description: todo 统一的返回结果
 */
@getter
@setter
public class ajaxresult {
 
    //是否成功
    private boolean success;
    //状态码
    private integer code;
    //提示信息
    private string msg;
    //数据
    private object data;
 
    public ajaxresult() {
    }
 
    //自定义返回结果的构造方法
    public ajaxresult(boolean success, integer code, string msg, object data) {
        this.success = success;
        this.code = code;
        this.msg = msg;
        this.data = data;
    }
 
    //自定义异常返回的结果
    public static ajaxresult defineerror(businessexception de) {
        ajaxresult result = new ajaxresult();
        result.setsuccess(false);
        result.setcode(de.geterrorcode());
        result.setmsg(de.geterrormsg());
        result.setdata(null);
        return result;
    }
 
    //其他异常处理方法返回的结果
    public static ajaxresult othererror(errorenum errorenum){
        ajaxresult result = new ajaxresult();
        result.setmsg(errorenum.geterrormsg());
        result.setcode(errorenum.geterrorcode());
        result.setsuccess(false);
        result.setdata(null);
        return result;
    }
}

二、自定义异常封装类

import lombok.getter;
import lombok.setter;
 
/**
 * @author: lawson
 * @date: 2021/5/11
 * @description: todo 类描述
 */
@getter
@setter
public class businessexception extends runtimeexception{
 
    private static final long serialversionuid = 1l;
 
    /**
     * 错误状态码
     */
    protected integer errorcode;
    /**
     * 错误提示
     */
    protected string errormsg;
 
    public businessexception() {
    }
 
    public businessexception(string message, integer errorcode, string errormsg) {
        super(message);
        this.errorcode = errorcode;
        this.errormsg = errormsg;
    }
}

三、错误枚举

**
 * @author: lawson
 * @date: 2021/5/11
 * @description: todo 类描述
 */
public enum  errorenum {
    //数据操作错误定义
    success(200, "成功"),
    no_permission(403, "你无权访问"),
    no_auth(401, "未授权,请登录验证"),
    no_found(404, "未找到资源"),
    internal_server_error(500, "服务器异常, 请联系管理员!");
 
 
    /**
     * 错误码
     */
    private integer errorcode;
    /**
     * 错误信息
     */
    private string errormsg;
 
    errorenum(integer errorcode, string errormsg) {
        this.errorcode = errorcode;
        this.errormsg = errormsg;
    }
 
    public integer geterrorcode() {
        return errorcode;
    }
 
    public string geterrormsg() {
        return errormsg;
    }
}

四、全局异常处理类

import com.jiusen.exercise.enums.errorenum;
import com.jiusen.exercise.exception.businessexception;
import com.jiusen.exercise.rest.ajaxresult;
import org.slf4j.logger;
import org.slf4j.loggerfactory;
import org.springframework.web.bind.annotation.exceptionhandler;
import org.springframework.web.bind.annotation.restcontrolleradvice;
 
 
/**
 * @author: lawson
 * @date: 2021/5/11
 * @description: todo 类描述
 */
@restcontrolleradvice
public class globalexceptionhandler {
 
    private static final logger log = loggerfactory.getlogger(globalexceptionhandler.class);
 
    /**
     * 处理自定义异常
     * @param e
     * @return
     */
    @exceptionhandler(value = businessexception.class)
    public ajaxresult bizexceptionhandler(businessexception e) {
        log.error(e.geterrormsg(), e);
        return ajaxresult.defineerror(e);
    }
 
    /**
     * 处理其它异常
     */
    @exceptionhandler(value = exception.class)
    public ajaxresult exceptionhandler(exception e) {
        log.error(e.getmessage(), e);
        return ajaxresult.othererror(errorenum.internal_server_error);
    }
}

五、测试

import com.jiusen.exercise.enums.errorenum;
import com.jiusen.exercise.exception.businessexception;
import com.jiusen.exercise.rest.ajaxresult;
import org.slf4j.logger;
import org.slf4j.loggerfactory;
import org.springframework.web.bind.annotation.exceptionhandler;
import org.springframework.web.bind.annotation.restcontrolleradvice;
 
 
/**
 * @author: lawson
 * @date: 2021/5/11
 * @description: todo 类描述
 */
@restcontrolleradvice
public class globalexceptionhandler {
 
    private static final logger log = loggerfactory.getlogger(globalexceptionhandler.class);
 
    /**
     * 处理自定义异常
     * @param e
     * @return
     */
    @exceptionhandler(value = businessexception.class)
    public ajaxresult bizexceptionhandler(businessexception e) {
        log.error(e.geterrormsg(), e);
        return ajaxresult.defineerror(e);
    }
 
    /**
     * 处理其它异常
     */
    @exceptionhandler(value = exception.class)
    public ajaxresult exceptionhandler(exception e) {
        log.error(e.getmessage(), e);
        return ajaxresult.othererror(errorenum.internal_server_error);
    }
}
