如何为ProxyFactoryBean设置许多目标?

本文介绍了如何为ProxyFactoryBean设置许多目标?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用Spring 4 AOP，现在，我将ProxyFactoryBean配置如下:

I am working with Spring 4 AOP and right now, i have my ProxyFactoryBean configured like this:

@Bean @Primary public ProxyFactoryBean proxyFactoryBean() { ProxyFactoryBean proxyFactoryBean = new ProxyFactoryBean(); proxyFactoryBean.setTarget(new ClientService()); proxyFactoryBean.addAdvice(new LoggingAdvice()); proxyFactoryBean.addAdvice(new DebugInterceptor()); return proxyFactoryBean; }

这有效，但是目标只是ClientService对象.

This works, but the target is just the ClientService object.

是否可以设置许多目标，而不仅仅是一个?如果可能的话，我想将这些建议设置在整个程序包中.否则，设置具体目标，但不仅要设置一个.你怎么能做到这一点 ?预先感谢

Is it possible to set many targets and not just one ? I want to set those advices to an entire package, if it is possible. Otherwise, set specifics targets, but again, not just one. How could you do that ? Thanks in advance

推荐答案

使用Spring的自动代理功能. las，切入点api在基于Java的配置中使用有点麻烦；我通常将 AbstractAutoProxyCreator子类化这样我就可以用Java代码表示切入点.

Proxying all beans in an application context that match certain criteria is easiest done with Spring's AutoProxy-Facility. Alas, the pointcut api is somewhat cumbersome to use in java based config; I usually subclass the AbstractAutoProxyCreator so I can express the pointcut in java code.

例如，我会做类似的事情:

For instance, I'd do something like:

@Bean AbstractAutoProxyCreator autoProxyCreator() { return new AbstractAutoProxyCreator() { @Override protected Object[] getAdvicesAndAdvisorsForBean(Class<?> beanClass, String beanName, TargetSource customTargetSource) { if (BusinessService.class.isAssignableFrom(beanClass)) { return new Object[] {loggingAdvice()}; } else { return DO_NOT_PROXY; } } }; } @Bean LoggingAdvice loggingAdvice() { return new LoggingAdvice(); } @Bean public PersonService personService() { return new PersonService(); }

此代码未经测试，因为我手头没有带有Spring(或Maven)的IDE，但是要旨应该可以.

This code is untested, as I don't have an IDE with Spring (or Maven) at hand, but the gist should work.
