webServices

Apache Bean log4j XML .net

开发环境 jdk1.4 myEclipse5.1 tomcat5.0 axis_1_2_1

使用axis 开发webServices还是比较方便快捷的

1.建立一个java类提供webServices调用的方法

//以下方法提供不同的参数类型及返回值类型
package test.rpc;

import test.bean.Employee;

public class JaxRpcService {

//param:string return:string
public String getEmployeeName(String employeeId){
String id = employeeId;
return "name";
}

//param:string return

bject
public Employee getEmployee(String employeeId){
Employee employee = new Employee();
employee.setId("1111111");
employee.setName("luo-yi-jun");
employee.setAddress("wu-Han");
return employee;
}

//return object[]
public Employee[] getEmployeeList(){
Employee employee = new Employee();
Employee employee1 = new Employee();
Employee[] employeeArray = new Employee[2];

employee.setId("1111111");
employee.setName("luo-yi-jun");
employee.setAddress("wu-Han");
employeeArray[0]=employee;

employee1.setId("2222222");
employee1.setName("luo-yi-jun-1");
employee1.setAddress("wu-Han-1");
employeeArray[1]=employee1;
return employeeArray;
}

}

//上面类中要用到的javaBean
package test.bean;

import java.io.Serializable;

public class Employee implements Serializable{

private String id;
private String name;
private String address;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

3.配置部署描述文件








<deployment name="test" xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">

<service name="webServices" provider="java:RPC" >
<namespace>http://soapinterop.org/</namespace>
    <parameter name="className" value="test.rpc.JaxRpcService"/>
    <parameter name="allowedMethods" value="*" />


    <typeMapping
        xmlns:ns="http://soapinterop.org/xsd"
        qname="ns:ArrayOfEmployee"
        type="java:test.bean.Employee[]"
        serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
        deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />

      <typeMapping
        xmlns:ns="http://soapinterop.org/xsd"
        qname="ns:Employee"
        type="java:test.bean.Employee"
        serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
        deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />

    <operation name="getEmployee" returnQName="return" returnType="RTypeNS:Employee" xmlns:RTypeNS="http://soapinterop.org/xsd">
        <parameter name="employeeId" type="xsd:string"/>
    </operation>

    <operation name="getEmployeeList" returnQName="return" returnType="RTypeNS:ArrayOfEmployee" xmlns:RTypeNS="http://soapinterop.org/xsd"/>

    <operation name="getEmployeeName" returnType="xsd:string">
        <parameter name="employeeId" type="xsd:string"/>
    </operation>

</service>

</deployment>

4.根据部署描述文件生成 server-config.wsdd 这个文件
首先编译工程,下载axis开发包将axis包解压到硬盘的某个位置(本例为d盘根目录下)
在工程的classes目录下新建一个批处理文件(*.bat)

SET AXIS_HOME=d:\
set CLASSPATH=%AXIS_HOME%/axis-1_2_1/lib/axis.jar;%AXIS_HOME%/axis-1_2_1/lib/log4j-1.2.8.jar;%AXIS_HOME%/axis-1_2_1/lib/commons-logging-1.0.4.jar;%AXIS_HOME%/axis-1_2_1/lib/jaxrpc.jar;%AXIS_HOME%/axis-1_2_1/lib/saaj.jar;%AXIS_HOME%/axis-1_2_1/lib/commons-discovery-0.2.jar;%AXIS_HOME%/axis-1_2_1/lib/wsdl4j-1.5.1.jar;%CLASSPATH%
java org.apache.axis.utils.Admin server deploy.wsdd

打开.bat文件将以上内容复制到刚才新建的.bat文件中(注意本人用的axis开发包解压缩后放在d盘根目录下上面的 "axis-1_2_1" 是axis解压后的文件夹名)

运行成功后则会在当前目录下server-config.wsdd 文件

5.在web.xml中加入
<servlet>
      <servlet-name>axis</servlet-name>
      <servlet-class>org.apache.axis.transport.http.AxisServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
      <servlet-name>axis</servlet-name>
      <url-pattern>/services/*</url-pattern>
</servlet-mapping>
6.将axis中的jar包拷贝到项目中
启动服务器输入 http://主机地址:端口号/项目名/services/
ok!

7.客户端测试
package client;

import org.apache.log4j.Logger;
import org.apache.axis.client.Call;
import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Service;
import java.net.MalformedURLException;
import java.net.URL;

public class BaseTest {

private static final Logger log=Logger.getLogger(BaseTest.class);

protected static String NAMESPACE="http://soapinterop.org/xsd";

protected static String hostName="127.0.0.1";

protected static String port="8080";

protected static String project="webServices";

protected static Call call;

protected static String wsName="webServices";

protected static String methodName;

public static Call getCall()throws ServiceException, MalformedURLException
{
if(wsName==null || methodName==null)
return null;

Service service=new Service();
Call call=(Call)service.createCall();
call.setOperationName(getOperationName());
call.setTargetEndpointAddress(getTargetEndpointAddress());

return call;
}

private static QName getOperationName(){
return new QName("http://" + hostName + ":" + port + "/" + project + "/services/" + wsName, methodName);
}

private static URL getTargetEndpointAddress() throws MalformedURLException{
return new URL("http://" + hostName + ":" + port + "/" + project + "/services/" + wsName + "?wsdl");
}
}

package client;

import javax.xml.namespace.QName;
import org.apache.axis.client.Call;
import org.apache.axis.encoding.ser.ArrayDeserializerFactory;
import org.apache.axis.encoding.ser.ArraySerializerFactory;

import test.bean.Employee;

public class EmployeeTest extends BaseTest{

public static void main(String args[])throws Exception
{

/* methodName = "getEmployeeName";
System.out.println("测试方法:" + methodName);
Call call = getCall();
Object[] obj = new Object[1];
obj[0] = "11111";
System.out.println(call.invoke(obj));

*/

//----------------------

/*
methodName = "getEmployee";
Call call = getCall();
QName qn1 = new QName(NAMESPACE, "Employee");
call.registerTypeMapping(Employee.class, qn1,
                new org.apache.axis.encoding.ser.BeanSerializerFactory(Employee.class, qn1),
                new org.apache.axis.encoding.ser.BeanDeserializerFactory(Employee.class, qn1));
Object[] obj1 = new Object[1];
obj1[0] = "1212";
Employee em =(Employee)call.invoke(obj1);
System.out.println("name:" + em.getName() +" id:" + em.getId() + " address:" + em.getAddress());
*/

//--------------------------------------------

methodName = "getEmployeeList";
Call call = getCall();

QName qn = new QName(NAMESPACE, "ArrayOfEmployee");
call.registerTypeMapping(Employee[].class, qn,
new ArraySerializerFactory(qn),
new ArrayDeserializerFactory(qn));

QName qn1 = new QName(NAMESPACE, "Employee");
call.registerTypeMapping(Employee.class, qn1,
                new org.apache.axis.encoding.ser.BeanSerializerFactory(Employee.class, qn1),
                new org.apache.axis.encoding.ser.BeanDeserializerFactory(Employee.class, qn1));

System.out.println("测试方法:" + methodName);
Object ojbect = call.invoke(new Object[]{});
Employee[] emp = (Employee[])ojbect;
System.out.println("length:" + emp.length);
for(int i=0; i<emp.length ;i++){
Employee e = emp[i];
System.out.println("name:" + e.getName() +" id:" + e.getId() + " address:" + e.getAddress());
System.out.println("------");
}
}
}
