In Spring, you can use @Autowired annotation to auto wire bean on the setter method, constructor or a field. There are two ways to can achieve it : 1.Using <context:annotation-config />     Just Add Spring context and <context:annotation-config /> in bean configuration file <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"     xmlns:tx="http://www.springframework.org/schema/tx"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd     http://www.springframework.org/schema/aop     http://www.springframework.org/schema/aop/spring-aop.xsd     http://www.springframework.org/sche...

To solve this problem. You have to do two things: 1. mark the DAO as transactional or function which is doing database call like:   @Transactional    public class EmployeeDaoImpl  extends DaoImpl implements EmployeeDao{  ///// }            OR @Transactional     public long addEmployee(Employee employee) {         System.out.println("Employee:"+employee );         long id = employeeDao.addEmployee(employee);         System.out.println("Id1: " );         return id;     } 2. Enable the annotation driven transcation management in applicationContext.xml (where your beans are defined): <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="ht...
