Spring MVC Controller mapping does not work

I am working on a spring-mvc project. After many tries, I am unable to the map the controller in spring. As a result, the below url always returns as 404 not found.
http://localhost:8080/EcommerceBookStore/rest/welcome
Here is the web.xml

I dont see any error in tomcat output. I expected something similar to appear
INFO: Mapped URL path [/welcome] onto handler HelloWorld.
I have no clue what's wrong. Can anyone please point out what I am missing ?
Thanks in advance.

I think you have mixed here:
If your project name is rest and you are deploying it as rest.war then you don't need this line in web.xml
<url-pattern>/rest/</url-pattern>
change it to
<url-pattern>/</url-pattern>
but if you are running it with ROOT.war and you want /rest in url then you have to do as below:
#Controller
#RequestMapping("/rest")
public class HelloWorld {
and then access with below url:
localhost:8080//rest/welcome

Try following,
#RequestMapping("/welcome", method = RequestMethod.GET)
public ModelAndView helloWorld() {...
Make sure your mapping is,
<servlet-mapping>
<servlet-name>Ecommerce</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Customize your default servlet name as,
<mvc:default-servlet-handler default-servlet-name="Ecommerce"/>
URL to try : localhost:8080/Ecommerce/welcome

Deploy Spring MVC 3 Rest on WebSphere Application Server 8

I am trying to deploy a Spring 3 MVC Rest Application on WebSphere Application Server 8.0 and have not had any success.
Here is my controller class
`
#Controller
public class BookingService {
public BookingService() {
System.out.println("test");
}
#RequestMapping(value="/test", method=RequestMethod.GET, produces="application/xml")
#ResponseBody
public String test() {
return "<test>test</test>";
}
}

I confirm that it does work on tomcat. In the tomcat logs the mapping is being created.

However in the was logs this does not appear and doing a curl http://localhost:9080/my-service-web/api/test returns 404 and the following response.
`

I was able to fix this. For some reason maven was not cleaning the WEB-INF/classes folder and my #Controller class was not available.

Data is inserted twice in database jpa/hibernate

Couldn't find what is wrong with inserting data in mySQL database using Spring data, JPA, hibernate and mySQL. It is inserting data twice in database.

My #Entity class is:

public class User {
#Id
#GeneratedValue
private Integer id ;
private String name ;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {

public void setName(String name) {

JPA repository is:
import org.springframework.data.jpa.repository.JpaRepository;
import com.project.entity.User;
public interface UserRepository extends JpaRepository<User, Integer> {
}
And, finally, #Service class is:
import javax.annotation.PostConstruct;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.project.entity.User;
import com.project.repository.UserRepository;
#Transactional
#Service
public class InitDbService {
#Autowired
private UserRepository userRepository;
#PostConstruct
public void init() {
User user = new User();
user.setName("Ali");
userRepository.save(user);
}
}
The above code works without errors/exceptions; database/table is also created but data is inserted into Entity/table twice when I see that in mySQL database.
Project is at github.

Taking a chance here since I see that you are using Spring MVC.
With Spring MVC, you have a servlet-context which defines the controllers, and an applicationContext for other beans. It might be that you are scanning for beans other than controllers in the servlet-context, which in turn will give you two beans of InitDbService, both running their #PostConstruct-method, inserting into the database.
This can be solved by defining component-scan like this:
servlet-context (after placing controllers and controllers only in a separate package):
<context:component-scan base-package="com.my.project.controller" />
applicationContext:
<context:component-scan base-package="com.my.project">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

You have to enable DEBUG logging to check that your initailizing bean isn't created twice, as Tobb mentioned before your bean is probabbly created in both contexts. Log stands clearly that first insert is executed during root context initialization (witch is correct) and second time during servlet context initialization (which is wrong)
I have found solution to your problem: You have to add commponent scan without default filters to your root-context
<context:component-scan base-package="com.project.db" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
and servlet-context is
<context:component-scan base-package="com.project.db" />
I have tested your project and its working fine with this change.

Hibernate cannot find suitable driver for Derby in Spring MVC webapp

I wonder if anyone can explain to me why a Spring and Hibernate webapp works perfectly well in two environments but fails in another? I'm using NetBeans 8.0.X with Tomcat 8.0.3.0 and Apache Derby 10.X.

It looks like derbyclient.jar is not present in your lib, So please add this jar in your libraries. Download it from here

I think it is about your connection string. Could you try it like this?
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
property name="driverClassName" value="org.apache.derby.jdbc.EmbeddedDriver" />
<property name="url" value="jdbc:derby:~/Library" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
This will create a database named Library on $USER_HOME.
Update
On default derby do not support connection string like jdbc:derby://localhost/Libarary . In order to connect a derby server over network you add derbynet.jar to your class path. You can find additional info here.
Then you can use your default datasource definition.
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.apache.derby.jdbc.ClientDriver" />
<property name="url" value="jdbc:derby://localhost:1527/Library" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>

Please tell me what is an issue in my code?
Thanks in advance..

In User.hbm.xml you have to use type="java.lang.String" (with a big 'S'). That's it.

AS I understand the problem in your code was caused by your User.hbm.xml mapping file. To be more precised by type="string" attribute of composite-id tab.
As I understand you don't need to put type attribute obligatory so try to skip it at all; hibernate should detect it automatically. I'm not sure in last sentece because I have not used composite keys, but there are a lot of examples where peoples don't define type explicitly.

Hmmm, in your mapping file you have
<key-property name="businessUnit" column="BusinessUnit" type="string"/>
<key-property name="userID" column="UserID" type="string"/>
That should be ...type="java.lang.String"... instead, but most likely you really don't need it - Hibernate will make a (usually very good) educated guess.
Cheers,

Hibernate use the reflection to determine the mapping type at runtime.
It seems your mapping is correct, But if you still getting the same problem.
I will suggest you to remove the type attribute for the time being test, from all the String type properties such as email,businessUnit,userId
try this way for all the String type properties
<property name="email">
<column name="Email"/>
</property>
or you can try with java.lang.String also
<property name="email" type="java.lang.String">
<column name="Email"/>
</property>

Both "string" and "java.lang.String" are aliases for org.hibernate.type.StringType, so either should work in terms of naming types.
I am actually not so sure the problem is in the mapping for User. That mapping looks fine. Based on that exception I would more expect that somewhere you have
<composite-id ... class="string">
or
<component ... class="string">
or something like that.

<composite-id name="userPK" >
<key-property name="businessUnit" column="BusinessUnit" type="String"/>
<key-property name="userID" column="UserID" type="String"/>
</composite-id>
try with changing string to String
