用Google Guice拦截构造函数 [英] Intercept a constructor with google guice

问题描述

我想用Google guice拦截构造函数.

I want to intercept a constructor with Google guice.

我在TYPE上添加了注释标记，但是"bindInterceptor"存在一些问题

I have added my annotation mark on TYPE but I have some problem with the "bindInterceptor"

如果我写

bindInterceptor(Matchers.annotatedWith(ReactToLoad.class),
                Matchers.any(),
                new ReactToLoadInterceptor());

这将在每种方法上运行拦截器. (很糟糕，很正常)

This will run the interceptor on each method. (it's bad and it's normal)

bindInterceptor(                Matchers.any(),
                                Matchers.annotatedWith(ReactToLoad.class),
                new ReactToLoadInterceptor());

如果我在下面运行代码，则必须将注释放在构造函数方法上(它可以工作)，但我更喜欢将此注释放在类的顶部.

If I run the code just below, I MUST put the annotation on the constructor method (it works) but I prefer to put this annotation on top of classes.

我只需要一个方法Matchers作为构造方法，但是我在使用谷歌搜索时找不到它.

I just need a method Matchers for the constuctor method but I don't find it with some googling.

你能帮我吗?

推荐答案

否，不可能拦截构造函数调用……仅是方法调用.我不知道您为什么要这样做，但是您可能想查看Guice的SPI，特别是

No, it isn't possible to intercept constructor calls... only method calls. I don't know why you want to do this, but you may want to look in to Guice's SPI, specifically InjectionListener.
