Is it possible to detect if an exception occurred before I entered a finally block?
I have a workflow method that does things, and throws an exception if an error occurred. I want to add reporting metrics to my workflow. In the finally block below, is there any way to tell if one of the methods in the try/catch block threw an exception ?
I could add my own catch/throw code, but would prefer a cleaner solution as this is a pattern I'm reusing across my project.
@Override
public void workflowExecutor() throws Exception {
try {
reportStartWorkflow();
doThis();
doThat();
workHarder();
} finally {
/**
* Am I here because my workflow finished normally, or because a workflow method
* threw an exception?
*/
reportEndWorkflow();
}
}
There is no automatic way provided by Java. You could use a boolean flag:
boolean success = false;
try {
reportStartWorkflow();
doThis();
doThat();
workHarder();
success = true;
} finally {
if (!success) System.out.println("No success");
}
