Question

I am using Spring’s AOPContext.currentProxy() in a @service class implementation. However, i am using it in a static method and I do something like

public static void addCustomer() {
    //....

    ((CustomerService) AopContext.currentProxy()).addCustomer();

    //...

However, I am getting the error — “cannot find proxy” set expose-proxy to true.

Is using static method the reason for this kind of error?

Note: “addCustomer” method is also static

Thanks in advance.

I’m not sure what you are trying to do, but you cannot do it this way at all.

Invocations of static methods are resolved at compile time, therefore they cannot be affected by proxy-based AOP. In other words:

• AopContext.currentProxy() inside a static method doesn’t make sense (unless you want to get a proxy for enclosing call of some instance method), because invocation of static method is not proxied
• Calling a static method on an instance returned by AopContext.currentProxy() doesn’t make sense, because it’s resolved at compile time using a static type of expression, i.e. it compiles into CustomerService.addCustomer().
