Apache CXF配置

配置

使用CXF可以非常方便的把普通的Java类发布为WebService。

首先在官网下载apache-cxf-3.1.1.zip,解压后把lib文件夹下的所有jar文件拷贝到项目中WebRoot/WEB-INF/lib目录下

然后配置web.xml，加入如下内容

<context-param>    <param-name>contextConfigLocation</param-name>    <param-value>      classpath:services.xml    </param-value>  </context-param>

contextConfigLocation的值指定了我们将要配置WebService的文件，而classpath信息记录在项目根目录下.classpath文件中

<listener>    <listener-class>      org.springframework.web.context.ContextLoaderListener    </listener-class>  </listener>

<servlet>    <servlet-name>CXFServlet</servlet-name>    <servlet-class>       org.apache.cxf.transport.servlet.CXFServlet    </servlet-class>    <load-on-startup>1</load-on-startup>   </servlet>  <servlet-mapping>    <servlet-name>CXFServlet</servlet-name>    <url-pattern>/services/*</url-pattern>  </servlet-mapping>

/services/*指定了访问WebService的路径

发布服务

然后编写服务的接口和实现类：
IRemoteIDEService.java

package com.jdeServer.service;import javax.jws.WebParam;import javax.jws.WebService;@WebServicepublic interface IRemoteIDEService {    //如果不用@WebParam指定参数名，则参数名会变成arg0    public String getCompileResult(@WebParam(name="sourceFileContent") String sourceFileContent);}

RemoteIDEServiceImpl.java

package com.jdeServer.service;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.OutputStream;import javax.naming.Context;import javax.naming.InitialContext;import javax.naming.NamingException;import Wgcc.dyGcc;public class RemoteIDEServiceImpl implements IRemoteIDEService {    @Override    public String getCompileResult(String sourceFileContent) {        String uploadDir = "";        String WebRoot="";        String output="";        try {            Context context = new InitialContext();            WebRoot=(String) context.lookup("WebRoot");            uploadDir = (String) context.lookup("uploadDir");            output=(String) context.lookup("output");        } catch (NamingException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        //创建源文件        File file = new File(WebRoot+uploadDir, "sourceFile.c");        if (!file.exists()) {            try {                file.createNewFile();            } catch (IOException e1) {                e1.printStackTrace();            }        }        //将代码写入源文件        try {            OutputStream out = new FileOutputStream(file, false);            out.write(sourceFileContent.getBytes());        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }        //编译源文件        String compileResult="";        dyGcc gcc=new dyGcc();        String errorFile=WebRoot+output+"\\error.txt";        try {            compileResult=gcc.compile(file.getAbsolutePath().toString(), errorFile);        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return compileResult;    }}

然后我们配置services.xml，其内容如下

<?xml version="1.0" encoding="utf-8"?><beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns:jaxws="http://cxf.apache.org/jaxws"      xmlns:jaxrs="http://cxf.apache.org/jaxrs"      xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-2.0.xsd         http://cxf.apache.org/jaxws         http://cxf.apache.org/schemas/jaxws.xsd         http://cxf.apache.org/jaxrs         http://cxf.apache.org/schemas/jaxrs.xsd">  <import resource="classpath:META-INF/cxf/cxf.xml"/><!--  本来按照官网文档导入多个resource，但是会报错，删除其余report后正常 --><jaxws:endpoint id="remoteide"      implementor="com.jdeServer.service.RemoteIDEServiceImpl"      address="/RemoteIDEService"/></beans>

在这里我们发布了一个服务，implementor指定了其实现类

启动服务器后访问http://[server ip address]:8080/[app name]/services/RemoteIDEService?wsdl
看到如下内容即表示WebService发布成功：

<xs:complexType name="getCompileResult"><xs:sequence><xs:element minOccurs="0" name="sourceFileContent" type="xs:string"/></xs:sequence></xs:complexType><xs:complexType name="getCompileResultResponse"><xs:sequence><xs:element minOccurs="0" name="return" type="xs:string"/></xs:sequence></xs:complexType>

<wsdl:operation name="getCompileResult"><soap:operation soapAction="" style="document"/><wsdl:input name="getCompileResult"><soap:body use="literal"/></wsdl:input><wsdl:output name="getCompileResultResponse"><soap:body use="literal"/></wsdl:output></wsdl:operation>

访问服务

上面的xml描述了这个WebService中的一个WebMethod，即getCompileResult
然后我们可以在客户端使用SOAP访问这个WebMethod：

RemoteCompileService.java

package com.jde.service;import android.content.Context;import com.jde.R;import utils.ContextUtil;import java.io.IOException;//使用下面这几个包的时候要导入ksoap2-android-assembly-3.2.0-jar-with-dependencies.jarimport org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;import org.xmlpull.v1.XmlPullParserException;/** * Created by chansonzhang on 2015/7/17. */public class RemoteCompileService {    static Context c= ContextUtil.getInstance();    private static final String SERVER= c.getString(R.string.server);    private static final String NAME_SPACE = "http://service.jdeServer.com/"; //对应服务器端的包名    private static final String WDSL_LINK = SERVER+"services/RemoteIDEService";    private String compileResult="";    public String getCompileResult() {        return compileResult;    }    public void setCompileResult(String compileResult) {        this.compileResult = compileResult;    }    public String getCompileResult(String sourceContent)    {        final String METHOD_NAME="getCompileResult";        final String SOAP_ACTION="";        /*此处的值可在wsdl中查到        如果写错会报出The given SOAPAction xxxx does not match an operation.*/        final String sContent=sourceContent;        //如果此处不使用线程，则会抛出android.os.NetworkOnMainThreadException,这是Android为了防止网络阻塞导致界面假死的举措        Thread thread=new Thread(){            public void run()            {                try {                    SoapObject request=new SoapObject(NAME_SPACE,METHOD_NAME);                    request.addProperty("sourceFileContent", sContent);//添加服务器端WebMethod所需的参数                    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(                            SoapEnvelope.VER11);                    envelope.bodyOut = request;                    envelope.dotNet = false;                    envelope.setOutputSoapObject(request);                    HttpTransportSE ht = new HttpTransportSE(WDSL_LINK);                    ht.call(SOAP_ACTION, envelope);                    String ret = String.valueOf(envelope.getResponse());                    setCompileResult(ret);                } catch (IOException e) {                    e.printStackTrace();                } catch (XmlPullParserException e) {                    e.printStackTrace();                }            }        };        thread.start();        try {            thread.join();        } catch (InterruptedException e) {            e.printStackTrace();        }        return compileResult;    }}
