如何解决java.sql.SQLException：无法构造描述符：TYPECODE_VARCHAR2无法解决类型错误？

Question

试图调用一个带有8个参数的oracle存储过程，而第8个是我们需要传递的数组。下面是代码段，并且抛出错误。我不确定将什么传递给createDescriptor方法作为参数1，因为无论传递什么，都会产生相同的错误。我从以下链接中获取了Fields继承的part的值（将非常感谢您的帮助）https://docs.oracle.com/cd/E16338_01/appdev.112/e13995/oracle/sql/ArrayDescriptor.html

  

java.sql.SQLException：无法构造描述符：无法解析java.sql.SQLException：无法构造描述符：TYPECODE_VARCHAR2

代码：

structDescriptor = StructDescriptor.createDescriptor("TYPECODE_VARCHAR2", oracleConnection.getMetaData().getConnection()); 
        arrayDescriptor = ArrayDescriptor.createDescriptor("TYPECODE_VARCHAR2", oracleConnection.getMetaData().getConnection()); 
        ARRAY arr = new ARRAY(arrayDescriptor, oracleConnection.getMetaData().getConnection(), accountArray); 
        try { 
            //Array array = oracleConnection.createARRAY("OBJECT", new Object[] { "176354516912167301", "177254516082228201" });
            OracleCallableStatement cstmt = (OracleCallableStatement) oracleConnection.prepareCall("{call COPY_FUNCTIONALITY.COPY_ADDRESS(?,?,?,?,?,?,?,?)}");

            cstmt.setString(1, "ABCD");
            cstmt.setString(2, "PASZKAL");
            cstmt.setString(3, "624954458340565301");
            cstmt.setString(4, "ALL");
            cstmt.setString(5, "RECURRING_ENTERED");
            cstmt.setBoolean(6, false);
            cstmt.setBoolean(7, false);
            cstmt.setArray(8, arr);
            //cstmt.setArray(8, array_to_pass);

            ResultSet rs = cstmt.executeQuery();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
