Java调用wcf

使用分布式编程，很方便不同编程语言之间互相访问，但也必须注意一些技术细节，实现起来才能畅通无阻，取得事半功倍的效果。

首先，创建一个WCF。使用原有网站或新建一个网站，并将端口动态改为固定，如设成8000。在网站中添加WCF服务，取名字为：GetAccountService.svc，这时同时生成了一个接口：IGetAccountService.cs和一个实现类：GetAccountService.cs，并且有一个默认方法。我们为了测试对数据库的访问，将方法改为：GetAccount。

完成的代码如下：

1．IGetAccountService.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.Text;



// 注意: 如果更改此处的接口名称 "IGetAccountService"，也必须更新 Web.config 中对 "IGetAccountService" 的引用。

[ServiceContract]

public interface IGetAccountService

{

[OperationContract]

Account GetAccount(String username);

}

2．GetAccountService.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.Text;

using System.Data;

using System.Data.SqlClient;



// 注意: 如果更改此处的类名 "GetAccountService"，也必须更新 Web.config 中对 "GetAccountService" 的引用。

public class GetAccountService : IGetAccountService

{



public Account GetAccount(String username)

{

String dbconn = global ::System.Configuration.ConfigurationManager.ConnectionStrings[ " ConnectionString " ].ConnectionString;

String sqlString = " SELECT userId, userName FROM UserAccount where userName=' " + username + " ' " ;

Account account = new Account();

using (SqlConnection conn = new SqlConnection(dbconn))

{

conn.Open();

SqlCommand cmd = new SqlCommand();

cmd.Connection = conn;

cmd.CommandText = sqlString;

SqlDataReader rd = cmd.ExecuteReader();



if (rd.Read())

{

account.Userid = Convert.ToInt32(rd[ " userId " ]);

account.Username = rd[ " userName " ].ToString();

}

}

return account;

}

}

3．代码涉及到一个Account对象：

using System;

using System.Data;

using System.Linq;

/// <summary>

/// Account 的摘要说明

/// </summary>

public class Account

{

private int m_userid;

private String m_username;



public Account()

{

//

// TODO: 在此处添加构造函数逻辑

//

}



public int Userid

{

get { return m_userid;}

set { m_userid = value; }

}



public String Username

{

get { return m_username; }

set { m_username = value; }

}

}

这时，右击GetAccountService.svc选择“在浏览器中查看”，可以看到服务已经运行，并且也打印出了访问服务的URL：“http://localhost:8000/WebWcf/GetAccountService.svc?wsdl”这个时候如果用.net来访问服务是没有问题的，但是如果用Java访问还是不行。程序上并没有错误，只是协议有点小问题。必须将Web.config中的wsHttpBinding改为：basicHttpBinding才行：

< system.serviceModel >

< behaviors >

< serviceBehaviors >

< behavior name ="GetAccountServiceBehavior" >

< serviceMetadata httpGetEnabled ="true" />

< serviceDebug includeExceptionDetailInFaults ="false" />

</ behavior >

</ serviceBehaviors >

</ behaviors >

< services >

< service behaviorConfiguration ="GetAccountServiceBehavior" name ="GetAccountService" >

< endpoint address ="" binding ="basicHttpBinding" contract ="IGetAccountService" >

< identity >

< dns value ="localhost" />

</ identity >

</ endpoint >

< endpoint address ="mex" binding ="mexHttpBinding" contract ="IMetadataExchange" />

</ service >

</ services >

</ system.serviceModel >

好了，现在可以用Java访问了。Java的访问工具比较好用的还是axis，可以到网上下载。有了axis后，可以编写一个脚本，用来生成一些基本代码。例如编写如下一个脚本，并存为wcf.bat文件：

set Axis_Lib = axis - 1_4\lib

set Java_Cmd = java - Djava.ext.dirs =% Axis_Lib %

set Output_Path = .

set Package = wcf

% Java_Cmd % org.apache.axis.wsdl.WSDL2Java http: // localhost: 8000 / WebWcf / GetAccountService.svc ? wsdl - o % Output_Path % - p % Package %

其中的lib为axis工具包中的lib目录，它包含了需要用到的Jar。在Dos下运行wcf.bat，即在当前目录中创建了目录wcf，并生成了五个Java程序，代码分别为：

1．  BasicHttpBinding_IGetAccountServiceStub.java
