Webserive Study Record 5-Interceptor Complete Login Check

　　Talk about CXF in the interceptor, can be divided into system interceptors (such as log interceptors) and custom interceptors, can also be divided into interceptors and into interceptors, can also be divided into server interceptors and client interceptors.

The following will implement a login to verify the Interceptor, where the user name is passed as a method parameter, the password is placed in the header of the XML sent to the server.

　　Service side

The code structure is as follows:

Logincheck: Inherits the Abstractphaseinterceptor, implements the Handlemessage method, obtains the password from the client to the SOAP message header, and is saved in the threadlocal variable for use when validating the user.

Client
The first is to generate the client code, not here,
　　　　
It then customizes an interceptor, writes the password information to the SOAP message header, the threadlocal variable used in the password, and the password in the test class into the threadlocal variable, and then the password is available in the interceptor.
The interceptor code is as follows:
Package Login.check.ws.client;import Java.util.list;import Javax.xml.namespace.qname;import Org.apache.cxf.binding.soap.soapmessage;import Org.apache.cxf.headers.header;import Org.apache.cxf.helpers.domutils;import Org.apache.cxf.interceptor.fault;import Org.apache.cxf.phase.abstractphaseinterceptor;import Org.apache.cxf.phase.phase;import org.w3c.dom.Document; Import Org.w3c.dom.element;import Login.check.ws.test.logintest;public class Passwordinterceptor extends abstractphaseinterceptor<soapmessage> {public passwordinterceptor () {super (phase.prepare_send);} @Overridepublic void Handlemessage (SoapMessage message) throws Fault {list
The test code is as follows:
Three interceptors were used and the passwords were stored in the threadlocal,
The test results are as follows:
