我正在尝试 sql 实用程序类 CallableStatement 该过程在 DB 中执行良好，但 arrayindex 超出范围错误是我得到的我试图调试它似乎 callablestatement 的语法有问题 

public int CalableStatement(String query,Login login,String type) throws ClassNotFoundException, SQLException
{    int  i =0;
    try {
    Connection con = getConnection();   
    //String q = query+"(?,?,?)";
    CallableStatement cst = con.prepareCall("call loginPlan_k(?,?,?)");

    //Login login = null ;
    //String type=lassType.getType();
    /*if(type.equals("login"))
    {
        login = (Login)o;
    }*/
    System.out.println(login.getUserName()+"DataAccess");
    cst.setString(1, login.getUserName());
    cst.setString(2, login.getPassword());
    cst.registerOutParameter(3,java.sql.Types.INTEGER);

    ResultSet rs = cst.executeQuery(query);
     if(rs.next())
     { i = cst.getInt(1);}
}catch (Exception e) {
    // TODO: handle exception
    e.printStackTrace();
}
    return i ;


}


}

这是我收到的错误

没有第三个参数，而是一些奇怪的@result 文本。用问号替换它。

  CallableStatement cst = con.prepareCall("{call loginPlan_k(?,?,?)}");

请参阅 Oracle 示例：http ://www.literak.cz/2013/08/working-with-complex-database-types-in-weblogic/

输出参数应由占位符表示，因为它们用于输入参数。你还需要用CallableStatements大括号括起来{}

CallableStatement cst = con.prepareCall("{call loginPlan_k(?,?,?)}");
