Spring JdbcTemplate 批量插入或更新操作

用 JdbcTemplate 进行批量插入或更新操作

方法一：

代码只是测试用的一个小例子。

public int insertContractAch(List list) throws DataAccessException {
final List temList = list;
String sql = "insert into contract_ach_t " +
" values(?,to_date(?,'yyyy-mm-dd'),?,?) ";
try{
int[] ii = this.getJdbcTemplate().batchUpdate(sql, new MyBatchPreparedStatementSetter(temList));
return ii.length;
}catch (org.springframework.dao.DataAccessException e) {
e.printStackTrace();
throw new DataAccessException(e.getMessage());
}
}
/**
* 处理批量插入的回调类
* */
private class MyBatchPreparedStatementSetter implements BatchPreparedStatementSetter{
final List temList;
/**通过构造函数把要插入的数据传递进来处理*/
public MyBatchPreparedStatementSetter(List list){
temList = list;
}
public int getBatchSize() {
return temList.size();
}

public void setValues(PreparedStatement ps, int i)
throws SQLException {
ContractAchVO contractAchVO = (ContractAchVO)temList.get(i);
ps.setString(1, contractAchVO.getContractCode());
ps.setString(2, contractAchVO.getCreateDate());
ps.setString(3, contractAchVO.getEmployeeId());
ps.setString(4, contractAchVO.getPercent());
}
}

方法二：

//插入很多书(批量插入用法)
public void insertBooks(List<Book> book)
{
final List<Book> tempBook=book;
String sql="insert into book(name,pbYear) values(?,?)";
jdbcTemplate.batchUpdate(sql, new BatchPreparedStatementSetter()
{
public void setValues(PreparedStatement ps,int i)throws SQLException
{
String name=tempBook.get(i).getName();
int pbYear=tempBook.get(i).getPbYear();
ps.setString(1, name);
ps.setInt(2, pbYear);
}
public int getBatchSize()
{
return tempBook.size();
}
});

}
