定义一个有用的 MyBaseException

import java.util.ArrayList; import java.util.List; public class MyBaseException extends Exception { public MyBaseException() { super(); } public MyBaseException(String message) { super(message); } public MyBaseException(String message, Throwable cause) { super(message, cause); } public MyBaseException(Throwable cause) { super(cause); } public static String getStackMsg(Throwable e) { StringBuffer sb = new StringBuffer(); StackTraceElement[] stackArray = e.getStackTrace(); sb.append(e.getClass().getName() + "\n"); for (int i = 0; i < stackArray.length; i++) { StackTraceElement element = stackArray[i]; sb.append(element.toString() + "\n"); } return sb.toString(); } public static List<String> getStackMsgList(Throwable e) { List<String> stringList = new ArrayList<>(); StackTraceElement[] stackArray = e.getStackTrace(); for (int i = 0; i < stackArray.length; i++) { StackTraceElement element = stackArray[i]; stringList.add( stackArray[i].getFileName() + "." + stackArray[i].getClassName() + "." + stackArray[i].getMethodName() + "." + stackArray[i].getLineNumber() ); } return stringList; } } 

@RequestMapping(value = "api") @ResponseBody public Result api() { Result<List<MyDto>> result = new Result(); try { result.setSuccess(true); result.setData(api.getAll()); } catch (Exception e) { result.setSuccess(false); result.setMsg(MyBaseException.getStackMsgList(e)); } return result; } class Result<T> { T data; boolean success = false; List<String> msg; public T getData() { return data; } public void setData(T data) { this.data = data; } public boolean isSuccess() { return success; } public void setSuccess(boolean success) { this.success = success; } public List<String> getMsg() { return msg; } public void setMsg(List<String> msg) { this.msg = msg; } } }
