Chapter 03rd creating soap messages using SAAJ

This is a Java project. Put the server code first.

The first is sei, that is, helloservice. Java, the server interface class.

Package COM. jadyer. service; import Java. util. list; import javax. JWS. webparam; import javax. JWS. webresult; import javax. JWS. webService; import COM. jadyer. model. user; @ webservicepublic interface helloservice {@ webresult (name = "loginresult") Public String login (@ webparam (name = "username") string username, @ webparam (name = "password") string password ); // here, both the return value and parameter name are defined as user // to generate both the SOAP request message and Response Message <user> <ID>... </ID> </user> regular XML // you can use jaxb to convert messages to JavaBean @ webresult (name = "user ") public user adduser (@ webparam (name = "user") User user); @ webresult (name = "user") public list <user> List ();}

Then there is SIB, that is, the server interface implementation class helloserviceimpl. Java

Package COM. jadyer. service; import Java. util. arraylist; import Java. util. list; import javax. JWS. webService; import COM. jadyer. model. user; @ WebService (endpointinterface = "com. jadyer. service. helloservice ") public class helloserviceimpl implements helloservice {// simulate a small warehouse in the memory Private Static list <user> Users = new arraylist <user> (); // initialize a user public helloserviceimpl () {users. add (new user (1, "admin", "Administrator", "222222") ;}@ overridepublic string login (string username, string password) {system. out. println ("login () is invoked ...... "); For (User: Users) {If (user. getUserName (). equals (username) & user. getPassword (). equals (password) {return "User [" + username + "] logon successful" ;}} return "User [" + username + "] Logon Failed ";} @ overridepublic user adduser (User user) {system. out. println ("adduser () is invoked ...... "); users. add (User); Return user ;}@ overridepublic list <user> List () {system. out. println ("list () is invoked ...... "); Return users ;}}

The following is the XML ing entity class user. java used by the server.

Package COM. jadyer. model; import javax. XML. BIND. annotation. xmlrootelement; @ xmlrootelementpublic class user {private int ID; private string username; private string nickname; private string password;/* setter and getter of the four attributes */public user () {} public user (int id, string username, string nickname, string password) {This. id = ID; this. username = username; this. nickname = nickname; this. password = password ;}}

The mainapp. java used to publish the service

package com.jadyer.server;import javax.xml.ws.Endpoint;import com.jadyer.service.HelloServiceImpl;public class MainApp {public static void main(String[] args) {Endpoint.publish("http://127.0.0.1:8888/myHelloService", new HelloServiceImpl());}}

So far, the WebServices server has been released.

The following is a demo of compiling a client with SAAJ.

Package COM. jadyer. client; import Java. io. stringreader; import Java. io. stringwriter; import java.net. URL; import javax. XML. BIND. jaxbcontext; import javax. XML. BIND. marshaller; import javax. XML. BIND. unmarshaller; import javax. XML. namespace. QNAME; import javax. XML. soap. messagefactory; import javax. XML. soap. soapbody; import javax. XML. soap. soapbodyelement; import javax. XML. soap. soapenvelope; import javax. XML. soap. s Oapmessage; import javax. XML. soap. soappart; import javax. XML. transform. source; import javax.

This standard format is soap * @ see. You can use SAAJ to manually generate soap messages, concurrently sent to the server, you can also receive the server response * @ see ------------- Author * @ see here we recommend a free tool required for WebServices soapui (http://www.soapui.org/) * @ see after it is used to create a new soapui project, we can clearly see the SOAP message format of the SOAP message to be sent and the response * @ see, which is of great help to understand this article .. similar to Apache tcpmon (http://ws.apache.org/commons/tcpmon/) * @ see Tables * @ creat E Mar 18,201 3 2:47:18 * @ author Xuan Yu 
The console outputs of the WebServices server and the client are listed respectively.
