java - Spring - 使用存储过程时使用 simplejdbccall 进行批量更新

Question

我正在使用 spring jdbc 模板，使用存储过程创建记录

public Long create(City $obj) {
    SimpleJdbcCall jdbcCall = new SimpleJdbcCall(getJdbcTemplate().getDataSource()).withProcedureName(SP_ADD_UPDATE);
    jdbcCall.declareParameters(new SqlOutParameter(ConstantUtil.RETUR_VAL, OracleTypes.BIGINT));
    Map<String, Object> jdbcCallResult = jdbcCall.execute(new MapSqlParameterSource(populateParams($obj)));
    return (Long) jdbcCallResult.get(ConstantUtil.RETUR_VAL);
}

参数

private static Map<String, Object> populateParams(City $obj) {

    Map<String, Object> _params = new HashMap<String, Object>();
    _params.put("CITYID", $obj.getCityId());
    _params.put("CITYNAME", $obj.getCityName());
    _params.put("USERID", $obj.getCurUser());
    return _params;

}

如何在使用存储过程的同时使用 simpleJdbcCall 进行批量更新？

我找到了使用 jdbcTemplate 的解决方案:

public int insertBatch(final List<ExperimentUser> usersByExperiment)
            throws Exception {

        int[] insertedRows = getJdbcTemplate().batchUpdate("call myschema.myProc(?,?)",
                new BatchPreparedStatementSetter() {

                    @Override
                    public void setValues(PreparedStatement ps, int i)
                            throws SQLException {
                        ExperimentUser experimentUser = usersByExperiment
                                .get(i);
                        ps.setInt(1, experimentUser.getExperimentId());
                        ps.setString(2, experimentUser.getUniqueCode());                        
                    }

                    @Override
                    public int getBatchSize() {
                        return usersByExperiment.size();
                    }
                });
        return insertedRows.length;
    }
