spring, aop, batch retry, exception: expected single bean but found 0

Question

I changed the code. the reason is bean can not be build.

If i don't add the retry, it works. If i don't add the retry, it works.

Thanks in advance.

I can only speek for myself, but I really did not understand what you asked for. May it would be helpful if you write a bit more text. and add the full stack trace — Ralph, Nov 06 '11 at 18:07

(1)Maybe, error is here: ApplicationContext ctx = new FileSystemXmlApplicationContext("test.xml"); xxImpl monitor = ctx.getBean(xxImpl.class); ApplicationContext ctx = new ClassPathXmlApplicationContext("file:spring-configuration/unit-testing/application-config.xml"); Main main = ctx.getBean(Main.class);

(2) Changed xxImpl, use @Autowired

(3) add CGLib

(4) it DOESN‘T works.

Finally, Solved！！！
Added
