java - Spring-Hibernate integration : Unable to persist -

i'm trying use hibernate in spring framework. following files :

employee.java :

package com.springstarter;      public class employee     {         private int id;          private string name;          private float salary;          public employee()         {         }          public employee( int id, string name, float salary )         {             super();             this.id = id;             this.name = name;             this.salary = salary;         }          public int getid()         {             return id;         }          public void setid( int id )         {             this.id = id;         }          public string getname()         {             return name;         }          public void setname( string name )         {             this.name = name;         }          public float getsalary()         {             return salary;         }          public void setsalary( float salary )         {             this.salary = salary;         }      }  employeedao.java      package com.springstarter;      import java.util.arraylist;     import java.util.list;      import org.springframework.orm.hibernate3.hibernatetemplate;      public class employeedao     {         hibernatetemplate template;          public void settemplate( hibernatetemplate template )         {             this.template = template;         }          public void saveemployee( employee e )         {             template.save( e );         }          public void updateemployee( employee e )         {             template.update( e );         }          public void deleteemployee( employee e )         {             template.delete( e );         }          public employee getbyid( int id )         {             employee e = ( employee ) template.get( employee.class, id );             return e;         }          public list<employee> getemployees()         {             list<employee> list = new arraylist<employee>();             list = template.loadall( employee.class );             return list;         }     } 

driver class :

package com.springstarter;  import org.springframework.context.applicationcontext; import org.springframework.context.support.classpathxmlapplicationcontext;  public class springormapp {     public static void main( string[] args )     {         applicationcontext ctx = new classpathxmlapplicationcontext( "springstarter.xml" );         employeedao dao = ( employeedao ) ctx.getbean( "edao" );         system.out.println( ( ( employee ) dao.getbyid( 1 ) ).getname() );     } } 

beans xml file :

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:p="http://www.springframework.org/schema/p"     xsi:schemalocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">     <bean id="datasource"         class="org.springframework.jdbc.datasource.drivermanagerdatasource">         <property name="driverclassname" value="oracle.jdbc.oracledriver" />         <property name="url" value="jdbc:oracle:thin:@[10.113.49.82]:1521:roc12c" />         <property name="username" value="milli_sec" />         <property name="password" value="milli_sec" />     </bean>     <bean id="mysessionfactory"         class="org.springframework.orm.hibernate4.localsessionfactorybean">         <property name="datasource" ref="datasource"></property>         <property name="mappingresources">             <list>                 <value>employee.hbm.xml</value>             </list>         </property>         <property name="hibernateproperties">             <props>                 <prop key="hibernate.dialect">org.hibernate.dialect.oracle9dialect</prop>                 <prop key="hibernate.hbm2ddl.auto">update</prop>                 <prop key="hibernate.show_sql">true</prop>             </props>         </property>     </bean>     <bean id="template" class="org.springframework.orm.hibernate3.hibernatetemplate">         <property name="sessionfactory" ref="mysessionfactory"></property>     </bean>      <bean id="edao" class="com.springstarter.employeedao">         <property name="template" ref="template"></property>     </bean> </beans>   

employee.hbm.xml file

<?xml version='1.0' encoding='utf-8'?>   <!doctype hibernate-mapping public   "-//hibernate/hibernate mapping dtd 3.0//en"   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  <hibernate-mapping>     <class name="com.springstarter.employee" table="employee">         <id name="id">             <generator class="assigned"></generator>         </id>         <property name="name"></property>         <property name="salary"></property>     </class> </hibernate-mapping>   

no compilation issues.but expecting employee object of id 1. following logs.

i think, main issue don't use transactions. reading data hibernate need transactions too. need extend springstarter.xml configuration transaction manager. can use @transactional annotation or add transactions methods methods masks in springstarter.xml.

and there problems in code

org.springframework.orm.hibernate3.hibernatetemplate

should be

org.springframework.orm.hibernate4.hibernatetemplate

public list<employee> getemployees() {     list<employee> list = new arraylist<employee>();     list = template.loadall( employee.class );     return list; } 

should

public list<employee> getemployees() {     return template.loadall( employee.class ); } 

and

hibernatetemplate template; 

should be

private hibernatetemplate template;
