[英]Java CDI interceptor not working web application with WELD
I have created a web application which uses Weld-2.2.0 CDI implementation and runs on Tomcat-7. 我创建了一个使用Weld-2.2.0 CDI实现并在Tomcat-7上运行的Web应用程序。 I have created an interceptor to log method calls.
我创建了一个拦截器来记录方法调用。 But when i run the application, it bypasses interceptor and calls method directly.
但是,当我运行该应用程序时,它会绕过拦截器并直接调用方法。
My interceptor constructs are as below: 我的拦截器构造如下:
Interceptor Binding: 拦截器绑定:
@Inherited
@InterceptorBinding
@Retention(RUNTIME)
@Target({METHOD, TYPE})
public @interface LogMe{
}
Interceptor class: 拦截器类别:
@LogMe
@Interceptor
public class LogInterceptorImpl
{
private static final Logger log = LogManager.getLogger(LogInterceptorImpl.class);
@AroundInvoke
public Object intercept(InvocationContext ctx) throws Exception
{
log.debug("LogInterceptor::intercept");
return ctx.proceed();
}
}
Interceptor Target: 拦截目标:
@LogMe
public class DefaultAppController extends AbstractBaseController
{
private static final long serialVersionUID = 1L;
public DefaultAppController()
{
}
@Override @LogMe
public void processRequest(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException
{
resp.getWriter().write("Hello, Guest !");
}
}
And finally i have created beans.xml file as below: 最后,我创建了beans.xml文件,如下所示:
<beans xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
<interceptors>
<class>x.web.interceptors.LogInterceptorImpl</class>
</interceptors>
</beans>
I have also created weld resource reference in context.xml file and web.xml file (as described by weld documentation. 我还在context.xml文件和web.xml文件中创建了焊接资源参考(如焊接文档所述)。
<Resource name="BeanManager"
auth="Container"
type="javax.enterprise.inject.spi.BeanManager"
factory="org.jboss.weld.resources.ManagerObjectFactory" />
And 和
<resource-env-ref>
<resource-env-ref-name>BeanManager</resource-env-ref-name>
<resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>
I tried lots of optins including using weld-tomcat-support jar for integration but none of them seems to be working. 我尝试了很多选择,包括使用weld-tomcat-support jar进行集成,但是似乎都没有用。
Can any one help me out here ? 有人可以帮我从这里出去吗 ?
Am i missing or doing something wrong here ? 我在这里想念还是做错了什么?
I don't think that interceptors are working outside a Java EE container. 我不认为拦截器在Java EE容器之外工作。 I guess standalone Weld can only do DI but not the other features.
我想独立的Weld只能做DI,而不能做其他功能。 See also this post: Is it possible to use javax.interceptor in a Java SE environment?
