Question

我在使用Bitronix将分布式事务执行到两个数据源时收到此警告“使用0登记资源执行事务”。有人可以帮助理解如何将资源登记到全局事务。我的代码是：

   import java.sql.Connection;
   import java.sql.PreparedStatement;
   import java.sql.SQLException;

   import javax.sql.DataSource;
   import javax.transaction.HeuristicMixedException;
   import javax.transaction.HeuristicRollbackException;
   import javax.transaction.NotSupportedException;
   import javax.transaction.RollbackException;
   import javax.transaction.SystemException;

   import bitronix.tm.BitronixTransactionManager;
   import bitronix.tm.TransactionManagerServices;

   public class TestMain {

     public static void main(String[] args) {

     new TestMain().TestDT();

   }

   private void TestDT(){

     DataSource dataSourceRemote = ConnectionManager.getDatasourceRemote();
     DataSource dataSourceLocal = ConnectionManager.getDatasourceLocal();
     Connection con, conn = null;
     try {


        /*String remoteDS = "remoteDS";
        String localDS = "localDS";
        InitialContext ctxRemote = new InitialContext();
        ctxRemote.bind(remoteDS, dataSourceRemote);*/

        String INSERT_QUERY = "insert emp values (?,?,?,?)";

        /*InitialContext ctxLocal = new InitialContext();
        ctxLocal.bind(localDS, dataSourceLocal);*/
        BitronixTransactionManager btx =         TransactionManagerServices.getTransactionManager();
        //DataSource dsRemote = null;
        //btx.ge
    //UserTransaction us =  


        try {

            btx.begin();


            //DataSource dsRemote = (DataSource) ctxRemote.lookup(remoteDS);
            con = dataSourceRemote.getConnection();
            //con.setAutoCommit(false);
            PreparedStatement pstmt = con.prepareStatement(INSERT_QUERY);

            for(int i=1; i<=5; i++){
                pstmt.setInt(1, i);

            //DataSource dsLocal = (DataSource) ctxLocal.lookup(localDS);
            conn = dataSourceLocal.getConnection();
            //conn.setAutoCommit(false);
            PreparedStatement ps = conn.prepareStatement(INSERT_QUERY);
            for(int i=1; i<=5; i++){
                ps.setInt(1, i);
                ps.setString(2, "Nikhil_"+i);
                ps.setString(3, "123"+i);

                ps.execute();
            }

            btx.commit();
            con.close();

        } catch (NotSupportedException e) {

    }

}
      }

“使用0登记资源执行事务”只是意味着您的数据源未与Bitronix事务管理器映射。
