Java WS和C#调用-JSP教程,Java技巧及代码

文章中的ws服务使得这个服务可以在dotnet环境中调用.

文件清单:

sei接口类iimage.java,实现sei接口的类iimageimpl.java,描述文件信息的值类型类fileinfo.java,web应用部署描述文件web.xml,ws发布配置文件jaxrpc-ri.xml,ws编译配置文件config-interface.xml,构建客户端桩的config-wsdl.xml,构建文件builder.xml

客户端测试类:form1.cs.

本例是从wsdl开始的,因此我们要有一个wsdl文件.第一步就是得到这个文件.

(一) 得到wsdl文件.

为达到互操作要求,这个文件的描述必须是文档样式的绑定,文字格式的编码.为得到此文件,首先介绍构建文件builder.xml:

   <classpath refid=”compile.classpath” />
  </wscompile>
 </target>
</project>

在这个构建文件中的build任务中, features的值指定为”wsi,documentliteral”,这个任务需要的config-interface.xml:

<?xml version=”1.0″ encoding=”utf-8″?>
<configuration xmlns=”http://java.sun.com/xml/ns/jax-rpc/ri/config”>
 <service name=”binaryservice” targetnamespace=”urn:binary”
  typenamespace=”urn:binary” packagename=”com.binary”>
  <interface name=”com.bin.iimage”
   servantname=”com.bin.imageimpl” />
 </service>
</configuration>

这个文件的需要的com.bin.iimage sei接口文件及其实现文件com.bin.imageimpl:

public interface iimage extends remote {
 //public datahandler fetchimg(string sn) throws remoteexception;
 //public datahandler[] fetchimgs(string[] sn) throws remoteexception;
 public soapmessage construcmsg(string[] fn) throws remoteexception;
 public byte[] fetchimage(string sn) throws remoteexception;
 public fileinfo[] fetchfilelist() throws java.rmi.remoteexception;
 public fileinfo getfilelist(string fn) throws java.rmi.remoteexception;
}

datahandler,arraylist属于java的类当然不允许出现在接口中了,因为c#不认识这些类,fileinfo值类型类倒支持,因为这个类没有方法,而且数据类型都是可以用soap来表示的,c#是可以理解的.

实现文件,注意实现的方法是空方法.

public class imageimpl implements iimage {
 public soapmessage construcmsg(string[] fn) throws remoteexception {
   return null;
  }
 public byte[] fetchimage(string sn) throws remoteexception{
  return null;
 }
 public fileinfo[] fetchfilelist() throws java.rmi.remoteexception{
  return null;
 }
  public fileinfo getfilelist(string fn) throws remoteexception {
  return null;
  }
}

到这里,为互操作所做的修改只是在 features的值指定为”wsi,documentliteral”,其它地方没有修改包括config-interface.xml接口配置文件.

通过执行这个任务,可以得到我们想要的binaryservice.wsdl文件.位于nonclass文件夹中,把它移动到conf中.

(二) 构造web服务

在这个conf文件夹中除了有binaryservice.wsdl外,还有两个文件:

config-client.xml,用来根据wsdl文件生成客户端访问服务所需要的制品.

<?xml version=”1.0″ encoding=”utf-8″?>
<configuration xmlns=”http://java.sun.com/xml/ns/jax-rpc/ri/config”>
 <wsdl
  location=”http://localhost:8080/netservice/binary?wsdl”
  packagename=”wsidotnet” />
</configuration>

config-server.xml则用来根据binaryservice.wsdl生成服务器端制品,包括重新生成的sei接口文件,我们将利用这个文件编写服务实现,而不是前面提到的com.bin.iimage sei接口文件及其实现文件com.bin.imageimpl:

<?xml version=”1.0″ encoding=”utf-8″?>
<configuration xmlns=”http://java.sun.com/xml/ns/jax-rpc/ri/config”>
 <wsdl location=”web-inf/conf/binaryservice.wsdl”
  packagename=”wsidotnet” />
</configuration>

到目前为止,还有两个文件没有提供:

jaxrpc-ri.xml:

<?xml version=”1.0″ encoding=”utf-8″?>
<webservices xmlns=”http://java.sun.com/xml/ns/jax-rpc/ri/dd”
 version=”1.0″
 targetnamespacebase=”http://java.sun.com/xml/ns/jax-rpc/wsi/wsdl”
 typenamespacebase=”http://java.sun.com/xml/ns/jax-rpc/wsi/types”
 urlpatternbase=”/ws”>

 <endpoint name=”imagebinaryservice” displayname=”stock example”
  description=”stock example web service endpoint”
  interface=”wsidotnet.iimage” implementation=”wsidotnet.iimage_impl”
  model=”/web-inf/model.xml.gz” />
 <endpointmapping endpointname=”imagebinaryservice” urlpattern=”/binary” />
</webservices>

web.xml文件:

<?xml version=”1.0″ encoding=”utf-8″?>
<web-app xmlns=”http://java.sun.com/xml/ns/j2ee”
 xmlns:xsi=”http://www.w3.org/2001/xmlschema-instance”
 xsi:schemalocation=”http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd”
 version=”2.4″>
 <context-param>
  <param-name>binarypath</param-name>
  <param-value>更改成你的本地文件路径</param-value>
 </context-param>
 <welcome-file-list>
  <welcome-file>index.htm</welcome-file>
  <welcome-file>index.jsp</welcome-file>
  <welcome-file>index.jws</welcome-file>
 </welcome-file-list>
</web-app>

下面就是构建过程,首先,执行wsi server service得到服务器端的java制品,包括重新生成的sei,wscompile还生成了一个实现文件iimage_impl ,后面要修改这个类,在其中加入有用的方法.

wsidotnet.iimage清单:

package wsidotnet;

public interface iimage extends java.rmi.remote {
    public wsidotnet.construcmsgresponse construcmsg(wsidotnet.construcmsg parameters) throws
         java.rmi.remoteexception;
    public wsidotnet.fetchfilelistresponse fetchfilelist(wsidotnet.fetchfilelist parameters) throws
         java.rmi.remoteexception;
    public wsidotnet.fetchimageresponse fetchimage(wsidotnet.fetchimage parameters) throws
         java.rmi.remoteexception;
    public wsidotnet.getfilelistresponse getfilelist(wsidotnet.getfilelist parameters) throws
         java.rmi.remoteexception;
}

和前面的com.bin.iimage接口相比很不同了.因为采用文档样式的绑定,所以这里就产生了所谓的包装类了.

实现文件为:

package wsidotnet;

import java.io.file;
import java.io.fileinputstream;
import java.nio.mappedbytebuffer;
import java.nio.channels.filechannel;
import java.util.calendar;
import java.util.date;

import javax.servlet.servletcontext;
import javax.xml.rpc.serviceexception;
import javax.xml.rpc.server.servicelifecycle;
import javax.xml.rpc.server.servletendpointcontext;

public class iimage_impl implements wsidotnet.iimage, java.rmi.remote,servicelifecycle {
 servletendpointcontext servletendpointcontext = null;

 string binarypath = “”;

 servletcontext servletcontext = null;
 
    public wsidotnet.construcmsgresponse construcmsg(wsidotnet.construcmsg parameters) throws
         java.rmi.remoteexception {
       
        wsidotnet.construcmsgresponse _retval = null;
        return _retval;
    }
    public wsidotnet.fetchfilelistresponse fetchfilelist(wsidotnet.fetchfilelist parameters) throws
         java.rmi.remoteexception {
        wsidotnet.fetchfilelistresponse _retval = new fetchfilelistresponse();
        _retval.setresult(fetchfilelist());
        return _retval;
    }
    public wsidotnet.fetchimageresponse fetchimage(wsidotnet.fetchimage parameters) throws
         java.rmi.remoteexception {
        wsidotnet.fetchimageresponse _retval = new fetchimageresponse();
        _retval.setresult(fetchimage(parameters.getstring_1()));
        return _retval;
    }

    public wsidotnet.getfilelistresponse getfilelist(wsidotnet.getfilelist parameters) throws
         java.rmi.remoteexception {
       
        wsidotnet.getfilelistresponse _retval = null;
        return _retval;
    }
 private fileinfo[] fetchfilelist() {
  file file = new file(this.binarypath);
  system.out.println(this.binarypath);
  file[] c = file.listfiles();
  fileinfo[] fis = new fileinfo[c.length];
  for (int i = 0; i < c.length; i++) {
   fileinfo fi = new fileinfo();
   fi.setisdir(c[i].isdirectory());
   fi.setfilename(c[i].getname());
   fi.setfilelength(c[i].length());
   fi.setfilepath(c[i].getabsolutepath());
   calendar cal=calendar.getinstance();
   cal.settime(new date(c[i].lastmodified()));
   fi.setcreatedate(cal);
   fis[i] = fi;
  }
  return fis;
 }

 private byte[] fetchimage(string sn) {
  file file = new file(sn);
  byte[] b=null;
  mappedbytebuffer buffer = null;
  try {
   fileinputstream is = new fileinputstream(file);
   b=new byte[(int)file.length()];
   is.read(b,0,(int)file.length());
   /*
   filechannel fc = is.getchannel();
   buffer = fc.map(filechannel.mapmode.read_only, 0, file.length());
   buffer.get
   */
  } catch (exception ex) {
   system.out.println(ex);
  }
  //return buffer.array();
  return b;
 }

 public void destroy() {
  // todo auto-generated method stub
  servletendpointcontext = null;
  servletcontext = null;
 }
 public void init(object arg0) throws serviceexception {
  // todo auto-generated method stub
  servletendpointcontext = (servletendpointcontext) arg0;
  servletcontext = servletendpointcontext.getservletcontext();
  binarypath = servletcontext.getinitparameter(“binarypath”);
 }
}

这里展示的实现类,已经过修改,让它扩展了servicelifecycle接口,以便运行环境送给它小金豆.这里就是获得了文件路径.此外,还提供了两个私有方法:fetchimage,fetchfilelist用于具体执行功能,这里也可以把这两个方法移动到一个新类,然后iimage_impl使用这个新类,使iimage_impl类变成调用者对外部类的适配器,这样就形成了一个适配器模式.

完成以上修改后,继续执行ant 任务:create-war,deploy后,得到了可供发布的netservice.war进行发布.本例使用tomcat5,检查http://localhost:8080/netservice/binary?wsdl是否装入.
发布成功后,用vs新建一个c#项目,通过这个地址http://localhost:8080/netservice/binary?wsdl引用这个服务,然后编写以下类:
