?最近有个需求,要在现有的WEB服务器上提供一个WebService服务,找资料后确定有两种方法可行,一种是用axis,另一种是利用xfire,由于之前有同事用axis做过,并且比较简单,所以确定用axis进行开发.下面我就把用axis开发的过程简单的记录下来:
第一步:下载相关的jar包,axis要用到的jar包有:axis.jar,activation.jar,commons-discovery.jar,jaxrpc.jar,wsdl4j.jar,saaj.jar(这个包是在运行客户端是用到的),这些jar包在axis的安装包里的lib下应该有的,接下来就是要把这些jar包部署到web应用的classpath中,例如部署到/web-inf/lib下.
第二步:修改web应用的web.xml配置文件,加上一个sevlet
<!--

?
?<!-- 利用axis做WEBSERVICE服务 20080219加入-->
?????? <!-- 下面的*.jws映射配置在本次应用中没有用到,可以不加-->
?<servlet-mapping>
?? <servlet-name>AxisServlet</servlet-name>
??? <url-pattern>*.jws</url-pattern>
? </servlet-mapping>
<!-- 我们将用下面的映射地址调用service服务,例如你配置的service服务的名称是TestService那么调用这个service的路径为http://localhost/,webServices/TestService,如果你的调用路径不同修改影射地址即可-->
? <servlet-mapping>
??? <servlet-name>AxisServlet</servlet-name>
??? <url-pattern>/webServices/*</url-pattern>
? </servlet-mapping>
?
<!-- 在文件的最后加上下面这段-->
?<!-- 利用axis做WEBSERVICE服务 20080219加入-->
? <mime-mapping>
??? <extension>wsdl</extension>
???? <mime-type>text/xml</mime-type>
? </mime-mapping>
? <mime-mapping>
??? <extension>xsd</extension>
??? <mime-type>text/xml</mime-type>
? </mime-mapping>
?
到此web.xml配置文件修改完成.
第三步:开发提供服务的java程序
?
package?com.test.webapp.webservice.server;
/**/
/**
?*?提供给PS商户校验用户密码的服务
?*?
?*?@author?
?*?@version?1.0,?
?*?@since?JDK?1.5.1
?*/
public
?
class
?PSCheckPsdService?
{
????public?PSCheckPsdService?()?{
????}
??/**
?????*?
?????*?验证结果一数组的形式返回给用户
?????*/
????public?String[]?checkPsd(String?yourName,String?password)?{
????????String?result[]?=?new?String[2];
????????if("xiaoming".equals(telNum)&&"000000".equals(password)){
????????????result[0]?=?"0";
????????????result[1]?=?"ok";
????????}else{
????????????result[0]?=?"1";
????????????result[1]?=?"密码不正确";
????????}
????????return?result;
????}
}
?
?提供服务的java程序完成,是不是很简单呢,就是和普通的java程序一样,不用导入什么特殊的类文件.
第四步:开发webservice的配置文件server-config.wsdd,我也不知道是不是必须是这个文件名,没有用过别的文件名去试,文件内容如下:

配置文件server-config.wsdd开发完成.
第五步:部署类文件到/web-inf/classes/中,重启服务
第六步测试:在浏览器中输入地址:?wsdl 测试service是否部署成功,如果出现如下结果即表示成功:

第六步:用axis开发的客户测试是否可以调通
package?com.sztelecom.webapp.webservice.test;
import?org.apache.axis.client.Service;
import?org.apache.axis.client.Call;
import?javax.xml.
namespace
.QName;
public
?
class
?Test?
...
{
????public?static?void?main(String[]?args)?...{
????????try?...{
????????String?name=?"xiaoming";
????????String?password?=?"000000";
????????String?endpoint?=?"http://localhost/webServices/TestService";
????????Service?service?=?new?Service();
????????Call?call?=?(Call)service.createCall();
????????call.setTargetEndpointAddress(endpoint);
????????call.setOperationName(new?QName("urn:TestService",?"checkPsd"));
????????String[]?result?=?(String[])call.invoke(new?Object[]...{name,password});
????????System.out.println("AXIS?Server?return:?"?+?result[0]);
????????}?catch(Exception?e)?...{
????????e.printStackTrace();
????????}
????????????
????????}
}
运行该程序,看看打印出来的是不是AXIS?Server?return:??0
以上程序在weblogic6.1中测试通过,tomcat正在部署中,有结果将会帖出来的,欢迎讨论相关技术,QQ:271537491
