SpringJDBC怎样批量操作数据

List<Map> paramMaps = new ArrayList<Map>();
for(int i = 0; i < 100; i++ ){
 Map paramMap = new HashMap();
 paramMap.put("param1", "param1");
 paramMap.put("param2", "param2");
 paramMap.put("param3", "param3");
 paramMap.put("param4", "param4");
 paramMap.put("param5", "param5");
 paramMaps.add(paramMap);
}
Map[] paramMap = paramMaps.toArray(new HashMap[paramMaps.size()]);

public void saveSpringJDBC(Map[] paramMap) throws Exception {
 NamedParameterJdbcTemplate namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(jdbcTemplate);
 StringBuffer sql = new StringBuffer();
 sql.append("Insert into 表名 ");
 sql.append(" (param1, param2, param3, param4) ");
 sql.append(" Values ");
 sql.append(" (:param1, :param2, :param3, :param4 ");
 namedParameterJdbcTemplate.batchUpdate(sql.toString(), paramMap);
}
public void ticketIssueCusInfo(Map[] paramMap) throws Exception{
 NamedParameterJdbcTemplate namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(jdbcTemplate);
 StringBuffer sql = new StringBuffer();
 sql.append(" UPDATE 表名 ");
 sql.append(" SET param1= :param1, param2 = :param2 ");
 sql.append(" WHERE param3 = :param3");
 namedParameterJdbcTemplate.batchUpdate(sql.toString(), paramMap);
}
