Spring容器外注入依赖

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;
	}

}

package test;

public class TestService {
	public String sayHello() {
		return "Hello";
	}
}

在META-INF里面加入aop.xml
<!DOCTYPE aspectj PUBLIC
"-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>

<include

<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());
}

}

楼主，你好。。我没有试成功，我在spring的reference上看到，并不用在JVM上加参数和创建AOP。XML，只是用了Configurable的Annotation,但是你的方法我也没试成功，应该被注入的对象引用是null,能不能再详细的解释下2.0 里的aspectj的容器外注射的原理，谢谢

这个是在ClassLoader级别植入的,不是靠动态代理,需要加jvm启动参数,你仔细看看reference

谢谢你，我搞定了，还挺麻烦。。呵呵不过性能差距太大

我做了个测试

构造5万个对象 用ASPECTJ植入和不植入的性能差距300倍，

50万个对象差距1000倍，汗。。。。

JRockit对AOP LTW做了优化，会快很多。
JVM 用-Xmanagement:class=org.aspectj.weaver.loadtime.JRockitAgent参数。

我用hibernate spring webwork 给DOMIAN MODEL注入总是发生莫名其妙的问题，很不稳定，例如这种错误
Caused by: org.springframework.beans.factory.BeanCreationException: Error creat
ng bean with name 'com.xxxx.domain.user.UserInfo$$EnhancerByCGLIB$$
3a79798': Error setting property values; nested exception is org.springframewor

PropertyAccessException 1: org.springframework.beans.MethodInvocationException:

yInitializationException: unexpected case hit, method=createHibernateTemplate

请问楼主 你在生产环境中使用过该方法吗？可靠吗？
