无法调用存储过程包含Varchar2_table作为Java中的参数

Question

I am trying to write the java code for calling stored procedure using SimpleJdbcCall feature. I am using Oracle 10g, Below is the procedure syntax need to call from our code

Stored Procedure Syntax:

CREATE OR REPLACE PROCEDURE  ImportFile(
      enametab IN VARCHAR2_TABLE,
      saltab IN DBMS NUMBER_TABLE)

Stored procedure is accepting the Varchar2.TABLE type and Number_TABLE type, Which is type of Bulk SQL Types. I have tried below code from java to call the stored procedure.

Java Code

SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(jdbcTemplate)

                .withSchemaName("<<schemaName>>")
                .withProcedureName("ImportFile")
                .declareParameters(new SqlParameter("enametab", Types.ARRAY),
                        new SqlParameter("saltab", Types.ARRAY));//

        // Creating lists

        List<String> enameList = new ArrayList<String>();
        enameList.add("one");
        enameList.add("two");

        List<Integer> salList = new ArrayList<Integer>();
        salList.add(1);
        salList.add(2);

        // Converting list into array
        String[] enameArray = enameList.toArray(new String[enameList.size()]);
        Integer[] salArray = salList.toArray(new Integer[enameList.size()]);

        MapSqlParameterSource in = new MapSqlParameterSource();
        in.addValue("enametab", enameArray);
        in.addValue("sArchiveName", salArray);

        // Executing the stored procedure
        simpleJdbcCall.execute(in);

After executing the above code I am getting error as

Caused by: java.sql.SQLException: Fail to convert to internal representation:

Any help/suggestions?

You need to use an oracle.sql.ArrayDescriptor to create an oracle.sql.ARRAY that holds the data. In the "Spring Data JDBC Extensions" project we handle this in the SqlArrayValue class. You could either implement this functionality yourself or use the convenience classes provided by the "Spring Data JDBC Extensions" project. See the docs .
