Hibernate and Spring Integration

Spring and Hibernate integrate key points:

1) Hibernate 's sessionfactory object is given to Spring to create;

2) hibernate transaction is given to spring 's declarative transaction management.

1. Deptdao.java

Data Access Layer Public class Deptdao { Spring and Hibernate Integration: IOC Container injection Private sessionfactory sessionfactory; Public void setsessionfactory (sessionfactory sessionfactory) { this. sessionfactory = Sessionfactory; } Save a record Spring and Hibernate Integration: Transaction management given to spring Public void Save (Dept Dept) { Sessionfactory.getcurrentsession (). Save (dept); } }

2. Deptservice

Public class Deptservice { Private Deptdao Deptdao; Public void Setdeptdao (Deptdao Deptdao) { this. Deptdao = Deptdao; } Public void Save (Dept Dept) { Deptdao.save (dept); } }

3. App.java Test

Public class App { Container Private ApplicationContext AC = new classpathxmlapplicationcontext ("Bean.xml"); @Test Public void testApp () throws Exception { Deptservice Deptservie = (deptservice) ac.getbean ("Deptservice"); System. out. println (Deptservie.getclass ()); Deptservie.save (new Dept ()); } }

4. Bean.xml Configuration "Spring management sessionfactory in 3 Ways"
