单元测试Spring @Around AOP方法

Question

我可以对大多数Spring类进行单元测试,而无需执行Spring"东西".

我也可以在不使用Spring的情况下对@Before建议方法进行单元测试:

示例代码:

@Before("execution(* run(..)) && " + "" +
          "target(target) && " +
        "args(name)")
public void logName(Object target, String name) {
    logger.info("{} - run: {}", target, name);
}

示例测试:

@Test
public void testLogName() {
    aspect.setLogger(mockLogger);
    aspect.logName(this,"Barry");
    assertTrue(mockLogger.hasLogged("TestAspect - run: Barry"));
}

但是@Around建议处理ProceedingJoinPoint对象:

@Around("com.xyz.myapp.SystemArchitecture.businessService()")
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
   // start stopwatch
   Object retVal = pjp.proceed();
   // stop stopwatch
   return retVal;
 }

我不知道如何实例化ProceedingJoinPoint对象.如何在不启动整个Spring应用程序上下文的情况下测试此类？

您可以通过以编程方式创建代理来测试Spring Aspect:

MyInterface target = new MyClass();
AspectJProxyFactory factory = new AspectJProxyFactory(target);
MyAspect aspect = new MyAspect(arg);
factory.addAspect(aspect);
MyInterface proxy = factory.getProxy();

...那么你可以调用方法proxy,并就断言aspect,proxy和target.
