带有 Grails 的 AOP [英] AOP with Grails

问题描述

我想在我的 Grails 项目中创建自定义日志注释.

I want to create a custom logging annotation in my Grails project.

我的代码:

class MyService{
    @AuditLog
    def method1() {
        println "method1 called"
        method2()
    }
    @AuditLog
    def method2() {
        println "method2 called"
    }
}

拦截器:

class AuditLogInterceptor implements MethodInterceptor {
    @Override
    Object invoke(MethodInvocation methodInvocation) throws Throwable {
        println "${methodInvocation.method}"
        return methodInvocation.proceed();
    }
}

弹簧配置:

aop {
    config("proxy-target-class": true) {
        pointcut(id: "auditLogInterceptorPointcut", expression: "@annotation(xxx.log.AuditLog)")
        advisor('pointcut-ref': "auditLogInterceptorPointcut", 'advice-ref': "auditLogInterceptor")
    }
}

auditLogInterceptor(AuditLogInterceptor) {}

结果:

public java.lang.Object xxx.MyService.method1()
method1 called
method2 called

我也想看到方法 2 的注解.我错过了什么?

I would like to see the annotation fire for method 2 as well. What am I missing?

推荐答案

出现这种情况是因为服务类中对 self 的内部方法调用没有在 服务的代理实例上完成 类.如果您从应用程序上下文中获取服务 bean 并尝试调用 method2()，您应该看到 aspect 正在监听 advice.>

This happens because the internal method calls in the service class to self are not done on the proxied instance of the service class. If you fetch the service bean from the application context and try to call method2() you should see the aspect listening to the advice.

class MyService{
    static transactional = false
    def grailsApplication

    @AuditLog
    def method1() {
        println "method1 called"
        grailsApplication.mainContext.myService.method2()
        //method2()
    }
    @AuditLog
    def method2() {
        println "method2 called"
    }
}
