项目异常处理
项目异常分类
业务异常
- 不规范的用户行为产生的异常
- 规范的用户行为产生的异常
系统异常
- 项目运行过程中可预计且无法避免的异常
其他异常
- 编程人员未预期到的异常
项目异常处理方案
业务异常
- 发送对应的消息,传递给用户,提醒规范操作
系统异常
- 发送固定消息传递给用户,安抚用户
- 发送特定消息给运维人员,提醒维护
- 记录日志
其他异常
- 发送固定消息传递给用户,安抚用户
- 发送特定消息给编程人员,提醒维护(纳入预期范围)
- 记录日志
实现步骤
自定义项目系统异常
package com.cqupt.exception;
public class SystemException extends RuntimeException{
private Integer code;
public SystemException(Integer code, String message) {
super(message);
this.code = code;
}
public SystemException(Integer code, String message, Throwable cause) {
super(message, cause);
this.code = code;
}
public Integer getCode() {
return code;
}
public void setCode(Integer code) {
this.code = code;
}
}
自定义项目业务异常
package com.cqupt.exception;
public class BusinessException extends RuntimeException{
private Integer code;
public BusinessException(Integer code, String message) {
super(message);
this.code = code;
}
public BusinessException(Integer code, String message, Throwable cause) {
super(message, cause);
this.code = code;
}
public Integer getCode() {
return code;
}
public void setCode(Integer code) {
this.code = code;
}
}
自定义异常编码(持续补充)
package com.cqupt.controller;
public class Code {
public static final Integer SAVE_OK = 20011;
public static final Integer DELETE_OK = 20021;
public static final Integer UPDATE_OK = 20031;
public static final Integer SELECT_OK = 20041;
public static final Integer SAVE_ERR = 20010;
public static final Integer DELETE_ERR = 20020;
public static final Integer UPDATE_ERR = 20030;
public static final Integer SELECT_ERR = 20040;
public static final Integer SYSTEM_ERR = 50001;
public static final Integer SYSTEM_UNKNOW_ERR = 59999;
public static final Integer BUSINESS_ERR = 60001;
}
拦截并处理异常
package com.cqupt.controller;
import com.cqupt.exception.BusinessException;
import com.cqupt.exception.SystemException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
@RestControllerAdvice
public class ProjectExceptionAdvice {
@ExceptionHandler(SystemException.class)
public Result doSystemException(SystemException ex){
// 记录日志
// 发送信息给运维
// 发送信息给编程人员
return new Result(ex.getCode(),null,ex.getMessage());
}
@ExceptionHandler(BusinessException.class)
public Result doBusinessException(BusinessException ex){
// 传递信息给用户
return new Result(ex.getCode(),null,ex.getMessage());
}
@ExceptionHandler(Exception.class)
public Result doException(Exception ex){
// 记录日志
// 发送信息给运维
// 发送信息给编程人员
return new Result(Code.SYSTEM_UNKNOW_ERR,null,"系统繁忙,请稍后再试");
}
}
