java – 没有通过单元测试执行的AspectJ建议

我很难过.我正在尝试测试一个AspectJ类.当我运行我的应用程序时,我的Aspect类被完美地拾取.但是,我似乎无法让任何Aspect类拦截测试中的任何方法.

我使用的是Spring 3.2.2,AspectJ 1.7.2和Maven 4.

这是我正在使用的简单测试：

测试AspectJ类

package my.package.path.config;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Aspect
public class TestAOP {
    private String message;

    public TestAOP() {
    }

    @pointcut("execution(* my.package.path.TestAOPClient.relayMessage(..))")
    public void aoppointcut() {
    }

    @Around("aoppointcut()")
    public String monitor(ProceedingJoinPoint pjp) throws Throwable {
        String msg = (String)pjp.proceed();
        this.setMessage(msg);
        return msg;
    }

}

正在拦截其方法的类

package my.package.path.config;

public class TestAOPClient {
    public String relayMessage(String msg) {
        return msg;
    }
}

测试类

package my.package.path.config;

import static org.hamcrest.Matchers.equalTo;
import static org.junit.Assert.assertthat;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

@Configuration
@ContextConfiguration(classes={WebConfig.class})
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration("src/main/java")
public class AopConfigTest extends AbstractJUnit4SpringContextTests {

     @Bean
     public TestAOP testAop() throws Exception {
        return new TestAOP();
     }

     @Test
     public void assertTestConfigIsActive() {
        TestAOPClient client = new TestAOPClient();
        client.relayMessage("hello");
        assertthat(((TestAOP)applicationContext.getBean("testAop")).getMessage(),equalTo("hello"));

    }
}

WebConfig文件

package my.package.path.web.context;
@Configuration
@EnableWebMvc
@EnableAspectJAutoproxy(proxyTargetClass=false)
@ComponentScan(value={"my.package.path.config","my.package.path.web"})
public class WebConfig {

}

总是,我会得到断言错误

Expected: "hello" but: was null

我的WebApplicationContext似乎被选中,因为在运行时,如果我指定一个不存在我的Aspect切入点的类,我将得到一个ApplicationContext无法加载错误.

我错过了什么？

@ContextConfiguration(classes={WebConfig.class})
@WebAppConfiguration("src/main/java")
public class AopConfigTest extends AbstractJUnit4SpringContextTests {

     @Autowired
     private TestAOP testAop;

     @Autowired
     private TestAOPClient client;

     @Test
     public void assertTestConfigIsActive() {
        client.relayMessage("hello");
        assertthat(((TestAOP)applicationContext.getBean("testAop")).getMessage(),equalTo("hello"));
    }

}

@Configuration
@EnableWebMvc
@EnableAspectJAutoproxy(proxyTargetClass=false)
@ComponentScan(value={"my.package.path.config","my.package.path.web"})
public class WebConfig {

    @Bean
    public TestAOP testAop() throws Exception {
        return new TestAOP();
    }

    @Bean
    public TestAOPClient testAopClient() throws Exception {
        return new TestAOPClient();
    }

}
