Axis开发webservice

最近的几个项目由于涉及到不同领域不同技术平台的应用,所以在各个系统的接口部分,采用了webservice技术,来实现不同系统的业务对接.

由于我们采用J2EE平台,下面着重讲下利用axis在J2EE平台开发和部署webservice应用的问题.

下面以一个用户登录的例子介绍开发的过程.

1. Axis开发包下载.

Apache的一个项目,请下载(略)

2. 编写方法

package zpf;

import java.util.*;

import java.io.*;

public class SSOWebservice

{

/**

登陆并得到用户信息

Public boolean login(String loginid, String password){

boolean ret=false;

if(loginid.equals(“zpf”)&&password.equals(“123”))

ret= true;

else

ret=false;

return ret;

}

/**

得到所有部门信息

public zpf.DepartmentInfo[] getAllDepts(){

zpf.Department dept=new zpf.Department();

zpf.DepartmentInfo[] ret=dept.getAllDepartment();

return ret;

}

http://localhost:8080/kmwhc/services/SSOWebservice

编译,通过,不在累述

3. 修改web.xml

加入如下代码

<listener-class>org.apache.axis.transport.http.AxisHTTPSessionListener</listener-class>

</listener>

<servlet-name>AxisServlet</servlet-name>

<display-name>Apache-Axis Servlet</display-name>

<servlet-class>

org.apache.axis.transport.http.AxisServlet

</servlet-class>

</servlet>

<servlet-name>AdminServlet</servlet-name>

<display-name>Axis Admin Servlet</display-name>

<servlet-class>

org.apache.axis.transport.http.AdminServlet

</servlet-class>

<load-on-startup>100</load-on-startup>

</servlet>

<servlet-name>SOAPMonitorService</servlet-name>

<display-name>SOAPMonitorService</display-name>

<servlet-class>

org.apache.axis.monitor.SOAPMonitorService

</servlet-class>

<init-param>

<param-name>SOAPMonitorPort</param-name>

<param-value>5001</param-value>

</init-param>

<load-on-startup>100</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>AxisServlet</servlet-name>

<url-pattern>/servlet/AxisServlet</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>AxisServlet</servlet-name>

<url-pattern>*.jws</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>AxisServlet</servlet-name>

<url-pattern>/services/*</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>SOAPMonitorService</servlet-name>

<url-pattern>/SOAPMonitor</url-pattern>

</servlet-mapping>

<!-- currently the W3C havent settled on a media type for WSDL;

http://www.w3.org/TR/2003/WD-wsdl12-20030303/#ietf-draft

for now we go with the basic 'it's XML' response -->

<mime-mapping>

<mime-type>text/xml</mime-type>

</mime-mapping>

<mime-mapping>

<mime-type>text/xml</mime-type>

</mime-mapping>

4. 布署

(1) WEB-INF下建立文件server-config.wsdd

(2) 文件内容如下:

蓝色部分定义了服务的名称,所用的类方法.

红色部分定义了服务的方法所用的返回值的自定义类型.

<?xml version="1.0" encoding="gb2312"?>

</handler>

</handler>

</requestFlow>

</globalConfiguration>

<service name="SSOWebservice" provider="java:RPC">

<parameter name="allowedMethods" value="*"/>

<parameter name="className" value="zpf.SSOWebservice"/>

<operation name="login" returnType="ns:boolean">

<parameter name="loginid" type="ns:String"/>

<parameter name="password" type="ns:String"/>

</operation>

<operation name="getAllDepts" returnType="ns:ArrayOf_tns2_DepartmentInfo">

</operation>

<typeMapping

xmlns:ns="http://interf.kmwhc.zpf.com"

qname="ns:DepartmentInfo"

type="java:zpf.DepartmentInfo"

serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"

deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"

<typeMapping

xmlns:ns="urn:SSOWebservice"

qname="ns:ArrayOf_tns2_DepartmentInfo"

type="java:zpf.DepartmentInfo[]"

serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"

deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"

encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

</service>

<namespace>http://xml.apache.org/axis/wsdd/</namespace>

</service>

</service>

</requestFlow>

</transport>

</responseFlow>

</transport>

</deployment>

文件修改完毕后，重新启动你的应用服务器.

5. 测试

在IE里输入http://localhost:8080/kmwhc/services/SSOWebservice

看到页面提示如下信息表示布署成功:

SSOWebservice

Hi there, this is an AXIS service!

Perhaps there will be a form for invoking the service here...

6. 编译生成客户端调用包

我用的ANT进行编译,在配置文件里加入如下代码

<java2wsdl output="${client.dir}/SSOWebservice.wsdl"

className="zpf.SSOWebservice"

namespace="urn:SSOWebservice"

location="http://localhost:8080/kmwhc/services/SSOWebservice">

<mapping namespace="urn:SSOWebservice"

package="zpf.client" />

</java2wsdl>

<wsdl2java url="${client.dir}/SSOWebservice.wsdl"

output="${client.dir}" deployscope="session" serverSide="yes"

skeletonDeploy="no" noimports="no" verbose="no" testcase="no">

<mapping namespace="urn:SSOWebservice"

package="zpf.client" />

</wsdl2java>

编译,生成wsdl文件和客户端代码.

7调用

调用代码:

zpf.client.SSOWebserviceServiceLocator sv=new zpf.client. SSOWebserviceServiceLocator();

zpf.client.SSOWebservice ssp=sv.getWebCaseservice(new java.net.URL("http://localhost:8080/kmwhc/services/SSOWebservice"));

boolean aa=ssp.login(“admin”,”123”);
