Java I'；m获取ClassCastException:WrappedPreparedStatementJDK8无法强制转换为SQLServerPreparedStatement

我的环境：面向企业Java开发人员的Eclipse IDE，版本：2019-09 R（4.13.0）

服务器：WildFly 13.0.0.Final

我正在尝试将数据批量上传到Sql Server，下面的代码在具有相同版本的WildFly服务器中运行良好，但在具有相同版本的WildFly服务器的客户端服务器机器中失败，java.lang.ClassCastException:org.jboss.jca.adapters.jdbc.jdk8.WrappedPreparedStatementJDK8无法强制转换到com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement在下面的语句中：

SQLServerPreparedStatement pStmt = (SQLServerPreparedStatement) con.prepareStatement(execStoredProc);

以下是完整的代码：

import com.microsoft.sqlserver.jdbc.SQLServerDataTable;
import com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement;

import java.sql.*;
import java.util.ArrayList;

public class DatabaseExtended extends Database {
    public DatabaseExtended(String assetDisposition, String assetDisposition_ds) {
        super(assetDisposition, assetDisposition_ds);
        // TODO Auto-generated constructor stub
    }

    public Object executeEstimateStructured(int iClientID, SQLServerDataTable sourceDataTable) {
        //boolean rs = false;
        ArrayList<String[]> lst = new ArrayList<String[]>();
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection con = DriverManager.getConnection(super.connectionUrl);
            Statement stmt = con.createStatement();
            String execStoredProc = "EXEC UploadEstimate ?,?";
            SQLServerPreparedStatement pStmt = (SQLServerPreparedStatement) con.prepareStatement(execStoredProc);//<--Exception here
            pStmt.setInt(1, iClientID);
            pStmt.setStructured(2, "dbo.UT_Estimate", sourceDataTable);
            ResultSet rs = pStmt.executeQuery();
            int columnCount = rs.getMetaData().getColumnCount();

            while (rs.next()) {

                int i = 1;
                String[] cols = new String[columnCount];
                while (i <= columnCount) {
                    cols[i - 1] = rs.getString(i++);
                }
                lst.add(cols);
            }
            con.close();
        }
        catch (SQLException e) {
            e.printStackTrace();
        }
        return lst;
    }
}

更新日期：2020年3月16日 这是我使用批处理语句更新的代码：

    public String executeInboundEstimateBatchedStoredProc(int iClientID, SQLServerDataTable sourceDataTable) {
        String message="";
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection con = super.getConnection();
            String execStoredProc = "EXEC UploadEstimate ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?";

            PreparedStatement pStmt = con.prepareStatement(execStoredProc);

            Iterator<Entry<Integer, Object[]>> itr1 = sourceDataTable.getIterator();
            while (itr1.hasNext()) {
                Object[] lst=  itr1.next().getValue();              
                int numColumns = lst.length;
                pStmt.setInt(1, iClientID);
                for (int i = 0; i < numColumns; i++) {
                    pStmt.setString(i+2, lst[i].toString());
                }
                // add single insert query
                pStmt.addBatch();
            }

            // Execute batch
            int[] counts = pStmt.executeBatch();

            if (pStmt != null) {
                pStmt.close();
            }
            if (con != null) {
                con.close();
            }
        }
        // Handle any errors that may have occurred.
        catch (SQLException | ClassNotFoundException e) {
            e.printStackTrace();
            message=e.getMessage();
        }
        return message;
    }

public String executeInBoundEstimateBackedStoredProc（int-iClientID，SQLServerDataTable-sourceDataTable）{
字符串消息=”；
试一试{
Class.forName（“com.microsoft.sqlserver.jdbc.SQLServerDriver”）；
Connection con=super.getConnection（）；
字符串execStoredProc=“EXEC UploadEstimate；
PreparedStatement pStmt=con.prepareStatement（execStoredProc）；
迭代器itr1=sourceDataTable.getIterator（）；
while（itr1.hasNext（））{
对象[]lst=itr1.next（）.getValue（）；
int numColumns=lst.length；
pStmt.setInt（1，iClientID）；
对于（int i=0；i

这是因为您不应该强制转换PreparedStatement，而应该使用unwrap。

con.prepareStatement（execStoredProc）.unwrap（SQLServerPreparedStatement.class）

U不必检查连接对象的准备语句的返回类型。依赖于平台的底层驱动程序可以提供自己的预处理语句接口的实现，而这与用户无关。你应该只使用接口提供的公共方法，而不是进一步挖掘。如果您没有错误，只需将您的语句强制转换为常规类型即可。PreparedStatement pStm=con.preparestatemt（execStoredProc）如果您正在处理一个我从您的execStoredProc中假定的过程，那么使用con.prepareCall（）并存储在一个可调用的语句类型中

我做了并删除了jboss-deployment-structure.xml，构建了war文件，现在得到以下异常：2020-03-13 08:57:24950错误[stderr]（默认任务4）java.sql.SQLException:IJ031030:不是com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement 2020-03-13 08:57:24950错误[stderr]（默认任务4）位于org.jboss.jca.adapters.jdbc.JBossWrapper.unwrap（JBossWrapper.java:96）您好，VISHAL，我想将记录批量插入数据库，而通用CallableStation没有我可以在表中传递的setStructured方法。有吗？有。您可以。首先使用setXXX方法设置批处理的参数，然后使用addBatch（）创建一批设置的参数。然后调用executeBatch（）在statementCallable语句上，它是prepared语句的子接口，只有额外的registerOutXXX方法，因此方法与Hi R VISHAL相同，感谢您的指导。我使用了可用的默认实现，而不是将其强制转换为SqlServer特定类型，然后使用addBatch方法来完成批量导入t、 PreparedStatement pStmt=con.prepareStatement（execStoredProc）；很高兴我能帮助您。请记住，setXXX方法和addBatch（）方法保存了要重用的语句对象的值，因此，如果您要放弃以前的数据和参数，请在重用语句对象之前始终使用clearbatch（）或clearParameters（）方法
