BeanNameAutoProxyCreator setBeanNames正则表达式不起作用? [英] BeanNameAutoProxyCreator setBeanNames regular expression not working?

问题描述

这是我的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();
}

这是我的ClientService bean:

And this is my ClientService bean:

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

所以，我不知道为什么，当我打电话给setBeanNames("*service")时，没有正确设置拦截器.如果我输入"* Service"，则会出现此异常:

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:

如果我输入"clientService"，它可以正常工作，但这不是我想要的.我希望所有以服务"结尾的bean都可以被拦截.但是由于某种原因，"*服务"无法正常工作.

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.

推荐答案

您必须设置

beanNameAutoProxyCreator.setProxyTargetClass(true);

，以便Spring使用CGLIB代理您的实例.否则，它将使用仅支持接口的JDK代理.

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

请注意，您当前正在(不知不觉中)代理可能由Web MVC配置注册的bean.这些不一定支持代理(例如final类).

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).
