BeanNameAutoProxyCreator setBeanNames regular expression not working?

问题

This is my BeanNameAutoProxyCreator:

@Bean
public BeanNameAutoProxyCreator beanNameAutoProxyCreator() {
    BeanNameAutoProxyCreator beanNameAutoProxyCreator = new BeanNameAutoProxyCreator();
    beanNameAutoProxyCreator.setBeanNames("*service"); // If i put "*Service" instead, then i get an exception. 
    beanNameAutoProxyCreator.setInterceptorNames("loggingAdvice", "debugInterceptor");
    return beanNameAutoProxyCreator;
}

@Bean
public LoggingAdvice loggingAdvice() {
    return new LoggingAdvice();
}

@Bean
public DebugInterceptor debugInterceptor() {
    return new DebugInterceptor();
}

And this is my ClientService bean:

@Bean
@Scope(BeanDefinition.SCOPE_PROTOTYPE)
public ClientService clientService() {
    return new ClientServiceImpl(this.clientDAO);
}

So, i don't know why, when i call setBeanNames("*service") is not setting properly the interceptors. If i put "*Service" then i get this exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is java.lang.ClassCastException: com.sun.proxy.$Proxy68 cannot be cast to org.springframework.format.support.FormattingConversionService

And if I put "clientService" it works fine but that is not what I want. I want that all beans that ends with "Service" then be intercepted. But for some reason, "*Service" is not working.

回答1:

You'd have to set

beanNameAutoProxyCreator.setProxyTargetClass(true);

so that Spring uses CGLIB to proxy your instances. Otherwise, it uses JDK proxies which only support interfaces.

Note that you're currently proxying (knowingly or unknowingly) beans that may be registered by your Web MVC configuration. These might not necessarily support proxying (final classes for example).
