我正在使用java 8.我使用jersey 2.26作为jax-rs实现。一切正常,但我无法登录。
我用eclipse生成了WS stub:

以下是我的资源类:
package mypackage;
import ...
/**
* Root resource (exposed at "myresource" path)
*/
@Path("myresource")
public class MyResource {
@EJB
private Service service;
private Logger logger = Logger.getLogger(getClass().toString());
/**
* Method handling HTTP GET requests. The returned object will be sent
* to the client as "application/json" media type.
*
* @return MyObject that will be returned as a application/json response.
*/
@GET
@Produces(MediaType.APPLICATION_JSON)
@Logged
public MyObject getIt() {
logger.info("LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOG");
//some computation
return result;
}
}
以下是我的LoggingFilter:
package log;
import ...
@Logged
public class LoggingFilter implements ContainerRequestFilter, ContainerResponseFilter {
private Logger logger = Logger.getLogger(getClass().toString());
@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
throws IOException {
logger.info("RESPOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOONSE");
logger.info(requestContext.toString());
logger.info(responseContext.toString());
}
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
logger.info("REQUEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEST");
logger.info(requestContext.toString());
}
}
以下是我的界面:
package log;
import ...
import javax.ws.rs.NameBinding;
@Target({ ElementType.TYPE, ElementType.METHOD })
@Retention(value = RetentionPolicy.RUNTIME)
@NameBinding
public @interface Logged { }
以下是我的web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html -->

<servlet-mapping>

永远不会调用LogginFilter中的过滤器方法。然而,打印“LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO”。

你必须在:
之间做出选择我选择了第一种可能性。

你需要的两件事。首先,使用以下内容
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>mypackage</param-value>
</init-param>
您只列出mypackage
作为要扫描的包,但过滤器位于log
包中。您可以添加用逗号分隔的log
包。
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>mypackage,log</param-value>
</init-param>
但一般来说,应该打包应用程序的方式是至少拥有一个root包,所有其他包都是子包。例如
com.foo.resources
com.foo.filters
这里com.foo
是根包。你可以在这里做的只是列表com.foo
作为要扫描的包,Jersey将递归扫描它,包括com.foo.resources
和com.foo.filters
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.foo</param-value>
</init-param>
您需要的第二件事是过滤器上的@Provider
注释。包扫描会查找要注册的@Path
和@Provider
注释类。
