Thread.setDefaultUncaughtExceptionHandler in Spring

Question

I am developing a Spring application, and was wondering if there a part of the framework that let's me do something like this in a more elegant way, such as configuring something in XML?

Answer 1

If the purpose of your question is to set a custom UncaughtExceptionHandler through your application context, you can use:

<bean id="myhandler" class="java.lang.ThreadGroup">
    <constructor-arg value="Test"/>
</bean>

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
   <property name="targetClass" value="java.lang.Thread"/>
   <property name="targetMethod" value="setDefaultUncaughtExceptionHandler"/>
   <property name="arguments">
     <list>
         <ref bean="myhandler" />
     </list>
   </property>
</bean>

(N.B. replace myhandler with an Thread.UncaughtExceptionHandler of choice...)

You can also use @ControllerAdvice annotated classes for uncaught exception handling. Referencing from https://spring.io/blog/2013/11/01/exception-handling-in-spring-mvc, the following code will catch any Exception:

@ControllerAdvice
public class MyUncaughtExceptionHandler {

    @ExceptionHandler(value = Exception.class)
    public void defaultExceptionHandler(Exception e) {
        // do whatever you want with the exception
    } 
}
