java调用存储过程-》游标解析返回的集合

     //存储过程名称
        String procedureName = PNAME_SINGLE_INDEX_DETAIL_LIST;
        
        //初始化参数集合
        List<String> params = Lists.newArrayList(singleIndexDetailRequestVo.getCurOrgId(),
            singleIndexDetailRequestVo.getCurOrgType(), singleIndexDetailRequestVo.getTimeDim(),
            singleIndexDetailRequestVo.getIndexId(),singleIndexDetailRequestVo.getPageNo(),singleIndexDetailRequestVo
            .getPageSize());

        //调用BI得到结果集
        List<Map<String, Object>> resultSet = getResultSet(procedureName, params);

2.处理参数转换占位符

 public List<Map<String, Object>> getResultSet(String procedureName, List<String> params) {
    List<Map<String, Object>> resultSet = null;
    try {
      String placeHolder = Joiner.on(",").join(params).replaceAll("\\w+", "?");
      resultSet = getCallProcedureResult(String.format("{call %s(%s,?)}", procedureName, placeHolder), params);
    } catch (Exception e) {
      resultSet = Lists.newArrayList();
      logger.error("call procedure:" + procedureName + " happened an exception:" + e.getMessage());
    }
    return resultSet;
  }

3.调用存储过程核心方法

/**
     *
     * @param procedureName 存储过程名称包含预编译参数 {call testpro(?,?)} 最后一个参数为输出参数为游标类型
     * @param params 对应存储过程执行参数是有顺序的，参数类型为字符类型 不包含存储的输出参数
     * @return
     */
    @Override
    @SuppressWarnings("unchecked")
    public List<Map<String,Object>> getCallProcedureResult(final String procedureName, final List<String> params) {
        final long startTime = System.currentTimeMillis();
        logger.info("开始调用存储过程【"+procedureName+"】，入参【" + JSON.toJSONString(params) + "】");
        List<Map<String,Object>> resultList = null;
        try {
            resultList = (List<Map<String,Object>>) biJdbcTemplate.execute(
                new CallableStatementCreator() {
                    public CallableStatement createCallableStatement(Connection con) throws SQLException {
                        String storedProc = procedureName;// 调用的sql
                        CallableStatement cs = con.prepareCall(storedProc);
                        for (int i=0; i< params.size();i++) {
                            cs.setString((i+1), params.get(i));// 设置输入参数的值
                        }
                        cs.registerOutParameter((params.size()+1),OracleTypes.CURSOR);// 注册输出参数的类型
