每日日报8月24日

1.今天学习了

使用 PrepraredStatement

public class Tester {
public void tx_insertDemo() {
Dao.dao.execute("delete from user");
Dao.dao.execute("insert user (username,age) values(" + W("user1") + "," + W(10) + ")");
Dao.dao.execute("insert user (username,age) values(" + W("user2", 20) + ")");
Dao.dao.execute("insert user (username,age) values(?,?)" + K("user3") + K(30));
Dao.dao.execute("insert user (username,age) values(?,?)" + K("user4", 40));
Dao.dao.execute(
"insert " + User.Table + " (" + User.UserName + "," + User.Age + ") values(" + W("user5", 50) + ")");
Dao.dao.execute("update user set username=?,address=? " + K("Sam", "BeiJing") + " where age=" + W(50));
User user = new User();
user.setUsername("user3");
user.setAge(40);
user.dao().save(); //TODO
}

public void tx_batchInsertDemo() {
for (int i = 6; i < 100000; i++)
Dao.dao.cacheSQL("insert user (username,age) values(?,?)" + K("user" + i, 60));
Dao.dao.executeCatchedSQLs();
}

public static void main(String[] args) {
Tester tester = BeanBox.getBean(Tester.class);//获取代理实例
tester.tx_insertDemo();//包装在Spring的声明式事务中
tester.tx_batchInsertDemo();
}
}

2.没有遇到问题
