我用的是java jdbc的addBatch批量插入数据，但是速度好慢有什么好的方案吗差不多插入1000条数据需要30s，下面贴出代码大家看看哪里不规范，或者给个更快的方法
//jdbc构造的URL是
private static final String URL="jdbc:mysql://localhost:3306/daan?useUnicode=true&characterEncoding=UTF8&rewriteBatchedStatements=true";
public static void writeData(LinkedList<Entity> entities)
{
con = DBUtil.getCon();
String sql = "INSERT INTO `test` (`title`,`url`,`year`,`grade`,`subject`,`publish`) VALUES (?,?,?,?,?,?)";
try {
PreparedStatement preparedStatement = con.prepareStatement(sql);
for (int i = 0;i<entities.size();i++)
{
Entity t = entities.get(i);
preparedStatement.setString(1,t.getTitle());
preparedStatement.setString(2,t.getUrl());
preparedStatement.setInt(3,t.getYear());
preparedStatement.setInt(4,t.getGrade());
preparedStatement.setInt(5,t.getSubject());
preparedStatement.setString(6,t.getPublish());
preparedStatement.addBatch();
//System.out.println(preparedStatement.toString());
preparedStatement.execute();
}
} catch (SQLException e) {
System.out.println("数据库错误"+e.getMessage());
}
}
