It is believed that many inexperienced people have no idea about how to deal with data in batches in SpringJDBC. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Parameters:

List paramMaps = new ArrayList (); for (int I = 0; I < 100; iTunes +) {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 ()])

Methods:

Public void saveSpringJDBC (Map [] paramMap) throws Exception {NamedParameterJdbcTemplate namedParameterJdbcTemplate = new NamedParameterJdbcTemplate (jdbcTemplate); StringBuffer sql = new StringBuffer (); sql.append ("Insert into table name"); 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 table name"); sql.append ("SET param1=: param1, param2 =: param2"); sql.append ("WHERE param3 =: param3"); namedParameterJdbcTemplate.batchUpdate (sql.toString (), paramMap);} after reading the above, have you mastered how to process data in batches in SpringJDBC?
