数据源

<data-sources>

  <!-- 设置数据源标识 -->
  <data-source key="sqlDB1" type="org.apache.commons.dbcp.BasicDataSource">

   <!-- 设置数据库驱动对应类名 -->
   <set-property property="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />

   <!-- 设置待连接数据源URL -->
   <set-property property="url" value="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=dbname" />

   <!-- 设置同时打开连接的最大数目 -->
   <set-property property="maxActive" value="5"/>  
   <set-property property="maxWait" value="5000" />  
   <set-property property="defaultAutoCommit" value="true" />
   <set-property property="defaultReadOnly" value="false" />  
   <set-property property="username" value="sa"/>
   <set-property property="password" value="sa"/>
  
  </data-source>
 </data-sources>

                                                                data Source 里的 key 是区分 数据源的（需要导包）

--------------------------Action中每个----------------------

DataSource ds=this.getSource(request);

model.insert(Userform f,DataSource ds);                     

------------------------传送到 bean---------------

public void insert (Userform f,DataSource ds)

bean接受  用  ds.getconection().preparestatement(sql);

 

------------------------------设置PlugIn------------------------------↑免-------

------------------------DbConn类----------------------------
public class DbConn implements PlugIn{
 Connection con;
 DataSource ds=null;
 public Connection SetCon(){
  try {
   con=ds.getConnection();
  } catch (SQLException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return con;
 }
 public void destroy() {
  // TODO Auto-generated method stub
  
 }
 public void init(ActionServlet servlet, ModuleConfig config)
   throws ServletException {
  ds=(DataSource) servlet.getServletConfig().getServletContext().getAttribute("org.apache.struts.action.DATA_SOURCE");
 }
}

-------------------------------------------Struts-config.xml--------------------------

<message-resources parameter="com.struts.ApplicationResources" />
  <plug-in className="com.common.DbConn" id="DbConn">
</plug-in>

---------------------配置完plugIn-------------------------------------------------
