Struts2 + spring + hibernate integration (2)

Inherit the hibernatedaosupport class from the business logic implementation class

Integrate using annotations (JSP file, Struts. XML is the same as the previous one)

JavaBean

 
@ Entity @ genericgenerator (name = "uid", strategy = "UUID") public class person {@ ID @ generatedvaluepublic int GETID () {return ID ;} public void setid (int id) {This. id = ID ;}@ columnpublic string getname () {return name;} public void setname (string name) {This. name = Name;} private int ID; private string name ;}
 

Business Logic

@ Component ("persondao") public class persondaoimpl extends hibernatedaosupport implements persondao {/* hibernatedaosupport class has two final Methods: setsessionfactory and sethibernatetemplate * which cannot be rewritten, but can be called, during the call, you can inject sessionfactory and hibernatetemplate into it. */@ Resource (name = "sessionfactory") Public void setsupersessionfactory (sessionfactory) {super. setsessionfactory (sessionfactory);} @ suppresswarnings ("Unchecked") public person checkuser (final int ID, final string username) {final string SQL = "from person P where P. ID =? And P. Name =? "; Return this.gethibernatetemplate(cmd.exe cute (New hibernatecallback <person> () {public person doinhibernate (Session arg0) throws hibernateexception, sqlexception {query = arg0.createquery (SQL ). setinteger (0, ID ). setstring (1, username); Return (person) query. list (). get (0 );}});}}
 

Service Layer

@ Component ("personservice") public class personserviceimpl implements personservice {private persondao; public person check (int id, string username) {return getpersondao (). checkuser (ID, username) ;}@ Resource (name = "persondao") Public void setpersondao (persondao) {This. persondao = persondao;} public persondao getpersondao () {return persondao ;}}
 

Action

@ Component ("loginaction") public class loginaction extends actionsupport implements modeldriven <person> {private personservice; private person; @ overridepublic string execute () throws exception {This. getpersonservice (). check (person. GETID (), person. getname (); Return success;} @ Resource (name = "personservice") Public void setpersonservice (personservice) {This. personservice = personservice;} public personservice getpersonservice () {return personservice;} public person GetModel () {If (person = NULL) person = new person (); Return person ;}}
