Class DefaultRuntimeException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

com.feilong.core.DefaultRuntimeException

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BeanOperationException, ReflectException, UncheckedIOException, URIParseException

public class DefaultRuntimeException
extends RuntimeException

默认的 RuntimeException.

主要作用,是在异常message 中追加 cause exception信息,方便查看排查问题

示例1:

如下代码

 
 public void testRuntimeException(){
     try{
         int i = 1 / 0;
     }catch (Exception e){
         throw new RuntimeException("", e);
     }
 }
 
 

抛出的异常情况在控制台是这样的:

java.lang.RuntimeException: 
    at com.feilong.core.DefaultRuntimeExceptionTest.testRuntimeException(DefaultRuntimeExceptionTest.java:63)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Caused by: java.lang.ArithmeticException: / by zero

而如果使用 DefaultRuntimeException

 
 public void testDefaultRuntimeException(){
     try{
         int i = 1 / 0;
     }catch (Exception e){
         throw new DefaultRuntimeException("", e);
     }
 }
 
 

抛出来的信息是这样的 :

示例2:

如下代码

 
 public void testRuntimeExceptionMessage(){
     try{
         int i = 1 / 0;
     }catch (Exception e){
         throw new RuntimeException("exception", e);
     }
 }
 
 

抛出的异常情况在控制台是这样的:

java.lang.RuntimeException: exception

而如果使用 DefaultRuntimeException

 
 public void testDefaultRuntimeExceptionMessageAppend(){
     try{
         int i = 1 / 0;
     }catch (Exception e){
         throw new DefaultRuntimeException("exception", e);
     }
 }
 
 

抛出来的信息是这样的 :
