如何更改连接访问的默认数据库？例如，即时通讯试图获取即时通讯连接到的SQL Server中每个表的列表：

List list = new ArrayList();
for (String db: dbList) {
    conn.prepareStatement("use ["+db+"]").executeQuery();//THIS LINE ISNT WORKING D:
    DatabaseMetaData md = conn.getMetaData();
    rs = md.getTables(null, null, "%", null);
    while (rs.next())
        list.add(rs.getString(3));
}
return list;

不起作用的行抛出此错误：

com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.
    at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDriverError(SQLServerException.java:171)
    at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.doExecutePreparedStatement(SQLServerPreparedStatement.java:394)
    at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement$PrepStmtExecCmd.doExecute(SQLServerPreparedStatement.java:340)

    at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:1400)
    at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(SQLServerStatement.java:179)
    at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(SQLServerStatement.java:154)
    at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.executeQuery(SQLServerPreparedStatement.java:283)

为每个数据库创建新连接不是一种选择。

我有完全相同的代码，只是以两种不同的方式编译。一个是 Spring 中的 maven 构建，另一个是 Jenkins 中的 maven 构建。

Spring 构建产生
