春天，aop，批次重试，例外：预计单一豆但发现0

我改变了代码。原因是bean无法建立。春天，aop，批次重试，例外：预计单一豆但发现0

如果我不添加重试，它的工作原理。如果我不添加重试，它会起作用。

我的问题：让 “重试” 的作品提前

感谢。

我只能为自己说话，但我真的不明白你的要求。如果你写更多的文字，这可能会有所帮助。并添加全堆栈跟踪 – Ralph

解决!!! 加链路以下：http://stackoverflow.com/questions/ 841231/fixing-beannotofrequiredtypeexception-on-spring-proxy-cast-on-a-non-singleton-be – Peter

（1）也许，错误在这里： 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）更改xxImpl，使用@Autowired

（3）添加CGLIB

（4）它不工作。

====== ====== ====== ======

最后，解决了!!!
新增

<aop:config proxy-target-class="true">
