从 java JDBCTemplate 调用具有 CLOB 类型输入参数的 Oracle 存储过程时出现问题答案

【问题标题】：Issues while calling Oracle stored procedure with CLOB type input parameter from java JDBCTemplate从 java JDBCTemplate 调用具有 CLOB 类型输入参数的 Oracle 存储过程时出现问题

【问题描述】：

我在 Sring 启动中使用 JDBCtemplate 功能并尝试调用具有 CLOB 类型输入参数的 oracle 存储过程。我使用 LobHandler 将输入字符串转换为 Clob，但我收到错误为“Caused by: java.sql.SQLException: ORA-22922: nonexistent LOB value”

Below is the sample code:

@Override
    public Map<String, Object> getNewRequestFids(String cisarResponse){
        Map<String, Object> resultMap = new HashMap<String,Object>();
        LobHandler lobHandler = new DefaultLobHandler();

        SimpleJdbcCall executor = new SimpleJdbcCall(jdbcTemplate).withProcedureName("CA_FID.GETREQUESTFIDS")
                .withoutProcedureColumnMetaDataAccess();
        executor.addDeclaredParameter(new SqlParameter("P_FIDLIST", Types.CLOB));
        executor.addDeclaredParameter(new SqlOutParameter("P_RESULT", OracleTypes.CURSOR, new FidExtractor()));

        executor.compile();
        SqlParameterSource params = new MapSqlParameterSource().addValue("P_FIDLIST", new SqlLobValue(cisarResponse, lobHandler));

        resultMap = executor.execute(params);
        System.out.println("The resultMap is: " + resultMap);

return resultMap;
}

Input to this function is like "finalJsonString.toString" where finalJsonString is "{"items":[{"id":7849081,"username":"marcinTest","description":"TEST DESCRIPTION","privileged":true,"critical":true,"system":{"id":4648,"systemName":"CBDEMLA1","description":"WPB - DEV","environment":"Production","type":"MIDRANGE","platform":null,"platformDetails":null,"sourceSystemId":null,"hostName":"CBDEMLA1","databaseAttributes":null},"owner":{"id":1010132677,"firstName":"MICHAL","lastName":"KOSTRZEWSKI","soeId":"MK32677"}}]}"

【解决方案1】：

我正在使用SqlLobValue 关注您的代码。我解决了将Clob 数据插入Oracle 11G 数据库的问题。
我的错误是ORA-22922: nonexistent LOB value


jdbcTemplate.setResultsMapCaseInsensitive(true);
simpleJdbcCall = new SimpleJdbcCall(jdbcTemplate).withCatalogName(FIDProcedures.PKG_FID);
simpleJdbcCall.withProcedureName(FIDProcedures.FID_LOG_UPDATE).declareParameters(
        new SqlParameter("P_LOG_ID", Types.NUMERIC), new SqlParameter("P_REQUEST", Types.CLOB),
        new SqlParameter("P_RESPONSE", Types.CLOB), new SqlParameter("P_ERROR_EXCEPTION", Types.CLOB),
        new SqlParameter("P_ENGINE_ELAPSE", Types.VARCHAR),
        new SqlParameter("P_STATUS", Types.VARCHAR));

Map<String, Object> paramaters = new HashMap<String, Object>();
paramaters.put("P_LOG_ID", logId);
paramaters.put("P_REQUEST", new SqlLobValue(request));
paramaters.put("P_RESPONSE", new SqlLobValue(response));
paramaters.put("P_ERROR_EXCEPTION", new SqlLobValue(error));
paramaters.put("P_ENGINE_ELAPSE", String.valueOf(elapse));
paramaters.put("P_STATUS", status);

simpleJdbcCall.execute(paramaters);

希望上面的代码能帮到你！
