bean declaration in dao project(spring_dao.xml)

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:context="http://www.springframework.org/schema/context"     xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:oxm="http://www.springframework.org/schema/oxm" xmlns:p="http://www.springframework.org/schema/p"     xsi:schemalocation="         http://www.springframework.org/schema/beans              http://www.springframework.org/schema/beans/spring-beans-3.2.xsd         http://www.springframework.org/schema/context          http://www.springframework.org/schema/context/spring-context-3.2.xsd  ">     <context:component-scan base-package="com.sanja.test.mydao" />     <context:annotation-config />   </beans> 

my entity

@entity public class user {  @id @generatedvalue(strategy=generationtype.auto) long id; string name;   public long getid() {     return id; } public void setid(long id) {     this.id = id; } public string getname() {     return name; } public void setname(string name) {     this.name = name; }  } 

my test class

public class app  {     @autowired     userdao userdao;      public static void main( string[] args )     {         applicationcontext context = new classpathxmlapplicationcontext("spring_service.xml");         app app=(app)context.getbean("app");         app.adduser();     }      @transactional(propagation = propagation.supports)     public void adduser(){           user user=new user();          user.setname("sanja ela");          userdao.save(user);              system.out.println("elane");      } } 

my dao logic

@repository("userdao") public class userdaoimpl implements userdao {      @persistencecontext     entitymanager entitymanager;       public user save(user user){          entitymanager.persist(user);         return user;      }   } 

i posted each , every code.

you using propagation.supports. if transaction not exists, operation non transactional (see javadoc propagation.supports).

support current transaction, execute non-transactionally if none exists.

give try using propagation.required(javadoc propagation.required);

support current transaction, create new 1 if none exists.
