// TODO Auto-generated method stub
MyUser u=new MyUser();
u.setName("springwegee");
u.setPassword("log4jIII");

testAOP(u);
}}问题是：Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myUserService' defined in class path resource [applicationContext.xml]: Initialization of bean failed;
