See the root cause: nested exception is java.lang.ClassNotFoundException: com.concept
remove the line <bean id="UserService" class="com.concept"/>
because com.concept is a package not a class. also you should not mix XML and Annotation based configuration.
And add #Repository to public class UserDAO implements UserService {
But i do not understand why you DAO implements an Interface called Service

What is wrong with my code?
Although you have defined the jdbcUserDAO bean, you have not wired it into the UserController class. This causes a NullPointerException because the jdbcUserDAO field is null, which results in the exception when jdbcUserDAO.getAllUsers() is called. To solve this, annotate the jdbcUserDAO setter in the UserController with #Autowired, as in:
#RestController
public class UserController {
private JdbcUserDAO jdbcUserDAO;
public JdbcUserDAO getJdbcUserDAO() {
return jdbcUserDAO;
}
#Autowired
public void setJdbcUserDAO(JdbcUserDAO jdbcUserDAO) {
this.jdbcUserDAO = jdbcUserDAO;
}
#RequestMapping("/")
#ResponseBody
public String welcome() {
return "Welcome to RestTemplate Example.";
}
#RequestMapping(value="/users", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public List<User> getAllUsers() {
System.out.println("jdbcUserDAO"+jdbcUserDAO);
List<User> userList = jdbcUserDAO.getAllUsers();
System.out.println(userList);
return userList;
}
}
The #Autowired annotation tells Spring that a bean that matches the interface of the parameter for the setter (in this case, JdbcUserDAO) should be injected into the setter, which results in the jdbcUserDAO field being set to your JdbcUserDAO bean defined in application_config.xml.
You could also simplify your UserController and annotate the field (removing the getter and setter):
#RestController
public class UserController {
#Autowired
private JdbcUserDAO jdbcUserDAO;
#RequestMapping("/")
#ResponseBody
public String welcome() {
return "Welcome to RestTemplate Example.";
}
#RequestMapping(value="/users", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public List<User> getAllUsers() {
System.out.println("jdbcUserDAO"+jdbcUserDAO);
List<User> userList = jdbcUserDAO.getAllUsers();
System.out.println(userList);
return userList;
}
}
For more information, see Guide to Spring #Autowired.
It also looks like your application_config.xml is not being included in Spring's application context. To include this XML file, change your ApplicationConfiguration class to resemble the following:
#ComponentScan(basePackages = {"com.ganeshTrading.riceAppService"})
#Configuration
#EnableWebMvc
#ImportResource("classpath:/path/to/application_config.xml")
public class ApplicationConfiguration {
}
Note that classpath:/path/to/application_config.xml is an example and the actual location of your application_config.xml file should be used instead.

Your jdbcTemplate bean expects a bean named datasource, like you have set-it-up here (in the ref=... part:
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="datasource" />
</bean>
But your datasource bean does not exist. The reason is because you have defined it as dataSource (notice the capital "S") in bean id="dataSource"
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value=";DatabaseName=" />
<property name="username" value="" />
<property name="password" value="" />
</bean>
So change this to "datasource" e.g. bean id="datasource" or change the reference in your jdbcTemplate to ref="dataSource"
Also the <property name="url" value=";DatabaseName=" /> doesn't look correct, I think you miss the correct value here, ";DatabaseName=" looks wrong or incomplete.
UPDATE
Since you are using xml spring configuration, the #Autowired annotation in your UserDaoImpl and UserServiceImpl classes is unnecessary. However, the xml configuration requires that the equivalent getters/setters exist. So change your code as:
In your UserDaoImpl you do not need the dataSource bean at all, so we are removing it.
public class UserDaoImpl implements UserDao{
JdbcTemplate jdbcTemplate;
public User validateUser(Login login) {
String sql = "select * from users where username='" + login.getUsername() + "' and password='" + login.getPassword()
+ "'";
List<User> users = jdbcTemplate.query(sql, new UserMapper());
return users.size() > 0 ? users.get(0) : null;
}
public JdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
}
You do need however the jdbcTemplate bean and in your xml definition you are not setting it, so update also your spring xml file to :
<bean name="userDao" class="com.cloudnexus.spring.dao.UserDaoImpl">
<property name="jdbcTemplate" ref="jdbcTemplate"></property>
</bean>
and
public class UserServiceImpl implements UserService{
private UserDao userDao;
public User validateUser(Login login) {
return userDao.validateUser(login);
}
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
}
Also you have another mistake in the spring xml configuration file. In the userService bean definition your are setting it again as a property:
<property name="userService" ref="userService"></property>
This is wrong, you should set the userDao there. Update it as:
<bean id="userService" class="com.cloudnexus.spring.service.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>

Sorry for the length of my problem...and how to fix this error?
Add<context:annotation-config />to your applicationcontext.xml. This should fix Auto-wiring issue!
I am getting following exception,please help to resolve this ?

When I try to run this code I am getting exception that I have posted. Autowired injection is not happening. What is the problem ?
Take a close look at the Exception, It says
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
It looks like you are not creating sessionFactory bean. Make sure you have sessionFactory added in you spring configuration
For Example :
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="${hibernate.config}"
/>
I am new in spring and hibernate, all thing is working fine but only Component annotation is not working. Each time this error is coming -
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.vc.teacher.db.dao.UserDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}

Your spring-servlet.xml says
<context:component-scan base-package="com.vc.teacher.controller" />
while the UserDao component is not in the controller package.
