本文介绍了一个使用Spring框架与AspectJ相结合的例子，展示了如何通过配置将AspectJ切面应用到Spring管理的bean上，实现了依赖注入和服务调用。

[code]
package test;

import org.springframework.beans.factory.annotation.Configurable;

@Configurable("testBean")
public class TestBean {
private TestService testService;

public TestService getTestService() {
return testService;
}
public void setTestService(TestService testService) {
this.testService = testService;
}

}
[/code]
[code]
package test;

public class TestService {
public String sayHello() {
return "Hello";
}
}
[/code]

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<aop:spring-configured />
<bean id="testService" class="test.TestService"

<bean id="testBean" class="test.TestBean" scope="prototype">
<property name="testService" ref="testService" />
</bean>
</beans>

在META-INF里面加入aop.xml
<!DOCTYPE aspectj PUBLIC
"-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
<aspects>
<include
within="org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect" />
</aspects>
<weaver
<include within="test.TestBean" />
</weaver>
</aspectj>

用的是aspectj的加载期植入代码,jvm的启动参数加上-javaagent:aspectjweaver.jar

现在来测试

package test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

public static void main(String... strings) {
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
"applicationContext-test.xml");
TestBean bean = new TestBean();
System.out.println(bean.getTestService());
}

}
