spring AOP Annotation的问题

先是用是spring的批注
applicationContext.xml：<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-2.5.xsd 
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <!-- 使用Spring的Annotation -->
<context:annotation-config />
<context:component-scan base-package="cn.text">
</context:component-scan>
......某个ManagerImpl中：@Service("d0510mgr")
@RemoteProxy(name = "d0510mgr")
public class D0510ManagerImpl{
......
}Action中：@Controller("D05_10action")
@RemoteProxy(name = "D05_10action")
public class D0510Action extends GenericAction {
private static final long serialVersionUID = 1L;
@Resource(name = "d0510mgr")
private D0510ManagerImpl mgr;
......可以正常使用没问题。
现在增加了spring的事务配置
applicationContext.xml：<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-2.5.xsd 
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <!-- 使用Spring的Annotation -->
<context:annotation-config />
<context:component-scan base-package="cn.text">
</context:component-scan>
<tx:annotation-driven transaction-manager="transactionManager" />
......
</beans>某个ManagerImpl中增加了一个方法：@Service("d0510mgr")
@RemoteProxy(name = "d0510mgr")
public class D0510ManagerImpl{
        @Transactional(propagation=Propagation.REQUIRED)
public boolean delete(Integer id){
......
}启动tomcat时出现了如下错误：

... 27 more什么原因呢？

解决方案 »

  1.   

    感觉好像是aop的annotation配置和原来的annotation冲突了？
      

  2.   


    怀疑是命名冲突了。最后在action中的@Resource(name = "d0510mgr")容器认为是@RemoteProxy(name = "d0510mgr")了，而并非@Service("d0510mgr")。没用过RemoteProxy也不知道这个是那个包里的，谷歌了下，说是dwr的。你可以把这个疑似dwr的注释先删掉，然后在运行下你的程序，看是否可以启动成功，如果可以，那就应该是命名冲突了。然后在换个名字看看。
    不太了解你的项目构成，只能大概看看，根据报错信息来看，应该是注入的类型不匹配发生了异常。
      

  3.   

    5楼兄弟，RemoteProxy是dwr的，注释掉仍然报同样错误
    感觉应该是Proxy的问题？
    错误里有这句话：
    Bean named 'd0510mgr' must be of type [cn.qianaq.manager.impl.D0510ManagerImpl], but was actually of type [$Proxy35]
