怎么建立一个WebService项目

如何建立一个WebService项目
(1) 首先新建一个项目,导入Spring和axis包
(2) 修改web.xml文件

<context-param>  <param-name>contextConfigLocation</param-name>  <param-value>/WEB-INF/applicationContext.xml</param-value></context-param><listener>  <display-name>contextConfigLocation</display-name>  <listener-class>    org.springframework.web.context.ContextLoaderListener  </listener-class></listener><servlet>  <servlet-name>axis</servlet-name>  <servlet-class>    org.apache.axis.transport.http.AxisServlet  </servlet-class>  <load-on-startup>2</load-on-startup></servlet><servlet-mapping>  <servlet-name>axis</servlet-name>  <url-pattern>/ws/*</url-pattern></servlet-mapping>

(3) 建立applicationContext.xml

<bean id="MathBean" name="code"><?xml version="1.0" encoding="UTF-8"?><deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">  <globalConfiguration>    <parameter name="adminPassword" value="admin"/>    <parameter name="sendXsiTypes" value="true"/>    <parameter name="sendMultiRefs" value="true"/>    <parameter name="sendXMLDeclaration" value="true"/>    <parameter name="axis.sendMinimizedElements" value="true"/>    <requestFlow>      <handler type="java:org.apache.axis.handlers.JWSHandler">        <parameter name="scope" value="session"/>      </handler>      <handler type="java:org.apache.axis.handlers.JWSHandler">        <parameter name="scope" value="request"/>        <parameter name="extension" value=".jwr"/>      </handler>    </requestFlow>  </globalConfiguration>  <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>  <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/>  <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/>  <!-- 需要修改的配置start -->  <service name="MathService" provider="java:RPC">    <parameter name="allowedMethods" value="*"/>    <parameter name="className" value="test.remote.JaxRpcMathService"/>    <beanMapping qname="wsdemo:MathVO" xmlns:wsdemo="urn:wsdemo" languageSpecificType="java:test.vo.MathVO"/>  </service>  <!-- 需要修改的配置end -->  <service name="AdminService" provider="java:MSG">    <parameter name="allowedMethods" value="AdminService"/>    <parameter name="enableRemoteAdmin" value="false"/>    <parameter name="className" value="org.apache.axis.utils.Admin"/>    <namespace>http://xml.apache.org/axis/wsdd/</namespace>  </service>  <service name="Version" provider="java:RPC">    <parameter name="allowedMethods" value="getVersion"/>    <parameter name="className" value="org.apache.axis.Version"/>  </service>  <transport name="http">    <requestFlow>      <handler type="URLMapper"/>      <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>    </requestFlow>  </transport>  <transport name="local">    <responseFlow>      <handler type="LocalResponder"/>    </responseFlow>  </transport></deployment>

(5)编写JaxRpcMathService类

public class JaxRpcMathService extends ServletEndpointSupport implements MathService {  private MathService mathService;  protected void onInit() {    this.mathService = (MathService) getWebApplicationContext().getBean(MathService.BEAN_ID);  }  public int add(int x, int y) {    return mathService.add(x,y);  }  public int subtract(int x, int y) {    return mathService.subtract(x,y);  }  public MathVO testVO(MathVO vo) {    return mathService.testVO(vo);  }}

(6)编写MathService接口类

public interface MathService {  String BEAN_ID = "MathBean";  public int add(int x, int y);  public int subtract(int x, int y);  public MathVO testVO(MathVO vo);}

(7)编写MathServiceImpl实现类

public class MathServiceImpl implements MathService{  public int add(int x, int y) {    return x+y;  }  public int subtract(int x, int y) {    return x-y;  }  public MathVO testVO(MathVO vo) {    System.out.println(vo.toString());    return vo;  }}

(8)客户端代码生成
通过eclipse打开Open Run Dialog

在main class中填入org.apache.axis.wsdl.WSDL2Java

在arguments中填入参数
-p src.com.test.vo http://localhost:8080/wsdemo1/ws/MathService?WSDL
启动tomcat,然后点击run生成代码

(9)代码生成完毕后编写客户端调用TestMathService类

public class TestMathService {  public static void main(String[] args) {    JaxRpcMathServiceService service = new JaxRpcMathServiceServiceLocator();    JaxRpcMathService client = service.getMathService();    System.out.println(client.add(1, 2));  }}
