spring jdbc批量入庫

//采用insert into replace 檢測(cè)手機(jī)號(hào)碼是否存在，存在更新，不存在新增

String sql = "insert into push_token(token,mobile) values(?,?) on DUPLICATE KEY UPDATE token = ?";

List args = new ArrayList();

for (int i = 0; i < tokens.size(); i++) {

Object[] objects = new Object[]{tokens.get(i), mobiles.get(i), tokens.get(i)};

args.add(objects);

}

//3000條提交一次

ArrayList temp = new ArrayList(3000);

List copy = null;

for (Object[] objects : args) {

temp.add(objects);

if (temp.size() >= 3000) {
