Aspectj and catching private or inner methods
提问by awonline
I've configureg AspectJ with Spring and it works fine when "catching" public methods called from out of the class. Now I want do something like this:
我已经使用 Spring 配置了 AspectJ，并且在“捕获”从类外调用的公共方法时它工作正常。现在我想做这样的事情：
public class SomeLogic(){
public boolean someMethod(boolean test){
if(test){
return innerA();
} else {
return innerB();
}
}
private boolean innerA() {// some logic}
private boolean innerA() {// some other logic}
}
SomeLogic is a SpringBean. The methods innerA() and innerB() could be declared as private or public - the method someMethod() is called from a Struts action. Is it possible to catch with AspectJ the methods innerA() or innerB() called from someMethod() ?
SomeLogic 是一个 SpringBean。方法innerA() 和innerB() 可以声明为private 或public - 方法someMethod() 是从Struts 操作中调用的。是否可以使用 AspectJ 捕获从 someMethod() 调用的方法 innerA() 或 innerB() ？
My config (XML based):
我的配置（基于 XML）：
<aop:aspect id="innerAAspect" ref="INNER_A">
<aop:pointcut id="innerAService" expression="execution(* some.package.SomeLogic.innerA(..))"/>
</aop:aspect>
<aop:aspect id="innerAAround" ref="INNER_A">
<aop:around pointcut-ref="innerAService" method="proceed"/>
</aop:aspect>
<aop:aspect id="innerBAspect" ref="INNER_B">
<aop:pointcut id="innerBService" expression="execution(* some.package.SomeLogic.innerB(..))"/>
</aop:aspect>
<aop:aspect id="innerBAround" ref="INNER_B">
<aop:around pointcut-ref="innerBService" method="proceed"/>
</aop:aspect>

Yes it is easy to catch private methods with AspectJ.
是的，使用 AspectJ 捕获私有方法很容易。
An example that prints a sentence before all private methods:
在所有私有方法之前打印一个句子的示例：
@Pointcut("execution(private * *(..))")
public void anyPrivateMethod() {}
@Before("anyPrivateMethod()")
public void beforePrivateMethod(JoinPoint jp) {
System.out.println("Before a private method...");
}
If you are familiar with Eclipse, I recommend to develop AspectJ with STSor only install the AJDT plugin.
如果你熟悉 Eclipse，我建议你用STS开发 AspectJ或者只安装AJDT 插件。
More information about Spring AOP capabilities can be found in the Spring reference documentation here.
