1、大致課程安排Hibernateday01、hibernate人門（hibernate操作數(shù)據(jù)查詢、新增、刪除、修改）1回顧：jdbc操作數(shù)據(jù)庫(kù)1創(chuàng)建表personid主鍵name姓名age年齡status是否刪除狀態(tài)0表示有效，1表示已刪除狀態(tài)2創(chuàng)建web項(xiàng)目3創(chuàng)建實(shí)體類(pojo、Entity)Person類intidStringnameintageStringstatuspackagecom.chinasofti.pojo;importjava.io.Serializable;@SuppressWarning
2、s("serial")publicclassPersonimplementsSerializable{privateIntegerid;privateStringname;privateintage;privateStringstatus;publicPerson(){}publicPerson(Stringname,intage,Stringstatus){super();this.name=name;this.age=age;this.status=status;}publicIntegergetId(){r

4、gstatus){this.status=status;}}4寫獲得Connection的JdbcUtil類packagecom.chinasofti.util;importjava.io.IOException;importjava.io.InputStream;importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.SQLException;importjava.util.Properties;publicclassJdbcU
5、til{privatestaticStringdriver;privatestaticStringurl;privatestaticStringusername;privatestaticStringpassword;privatestaticThreadLocaltlc=newThreadLocal();//靜態(tài)代碼塊static{Propertiesprop=newProperties();//jdbc.properties文件與JdbcUtil在同一目錄下In
6、putStreaminStream=JdbcUtil.class.getResourceAsStream("jdbc.properties");try{prop.load(inStream);driver=prop.getProperty("driver");url=prop.getProperty("url");username=prop.getProperty("user");password=prop.getProperty("password");}catch(IOExceptione){e.printS

8、ace();}}returncon;}publicstaticvoidcloseConnection(Connectioncon){if(con!=null){try{con.close();}catch(SQLExceptione){e.printStackTrace();}}}}5創(chuàng)建Dao類Dao是用來(lái)操作數(shù)據(jù)庫(kù)數(shù)據(jù)的對(duì)象packagecom.chinasofti.
