Nikita Koksharov opened SPR-7566 and commented

Here is my spring config:

\<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:sec="http://www.springframework.org/schema/security" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util" xmlns:task="http://www.springframework.org/schema/task"

<task:annotation-driven/>

<bean class="com.tests.TestBean"/>

\

Here is my classes:

package com.tests;

import org.springframework.scheduling.annotation.*;

public class TestBean implements ITestBean {

@Scheduled(fixedDelay = 1000)
public void scheduleMethod() {

}

@Async
public void asyncMethod() {

}

}

package com.tests;

public interface ITestBean {

void asyncMethod();

}

On spring context creation i got follow exception:

I'm afraid that you'll have to expose your scheduleMethod on the ITestBean interface, since @Async enforces an interface-based proxy for your TestBean - and @Scheduled invocations will be delegated to that proxy as well then.

Do you suggest to add "void scheduleMethod()" signature to ITestBean interface? But this method should be invoked by spring only. Don't want to add it to interface.

chris marx commented

I don't really mind having to add it to an interface, but it might be nice if the error said as much, rather than having it say "failed to prepare task" and then searching google for this post...(thanks though, interface method added and it works)

I have seen this problem as well.

In my case, I had a method that originally looked like this:

@Scheduled(fixedDelay = 10000)
@Transactional
public void foo() {
    ...
}

and it worked fine. When I tried to add my own custom @AspectJ style annotation, it failed with the same exception as reported in this bug:

@Scheduled(fixedDelay = 10000)
@Transactional
@PostCompletionSupport
public void foo() {
    ...
}

Archie Cobbs commented

Following up on my previous comment above...

The addition of the @PostCompletionSupport annotation was actually not necessary to trigger this bug: the bug still occurs without that annotation, if I simply add <aop:aspectj-autoproxy/> to the application context.
