Spring and Jersey rest api returned 404 - spring

Question

i tried to make rest api with spring and jersey.
this is my web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<servlet>
<servlet-name>Jersey Spring Web Application</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Jersey Spring Web Application</servlet-name>
<url-pattern>/FjordRestApi/*</url-pattern>
</servlet-mapping>
</web-app>
and this is my service file:
package com.persistent.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import com.persistent.entity.User;
import com.persistent.entity.UsersList;
#Path("/us")
#Component
public class UsersService {
#Autowired
SessionFactory sessionFactory;
#GET
#Transactional
#Path("/getUsers")
#Produces("application/json")
#SuppressWarnings("unchecked")
public UsersList getUsers() {
final Session session = sessionFactory.getCurrentSession();
final Criteria criteria = session.createCriteria(User.class);
criteria.add(Restrictions.eq("risk", 1));
return new UsersList(criteria.list());
}
}
when i used ServletRunner with the method getResponse
like this:
public void testFoo() {
WebResponse response;
try {
response = getClient().getResponse("http://localhost:8282/FjordRestApi/us/getUsers");
System.out.println(response.getText());
} catch (Exception e) {
e.printStackTrace();
}
}

Answer 1

I think your configurations needs to add init-param for jersey ( depends on your version of jersey ofcourse ) .
try to add :
<servlet>
<servlet-name>jersey-serlvet</servlet-name>
<servlet-class>
com.sun.jersey.spi.spring.container.servlet.SpringServlet
</servlet-class>
<init-param>
<param-name>
com.sun.jersey.config.property.packages
</param-name>
<param-value>your package</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
I advice you to read the docs of jersey for the providers config
,if doesn't work ( depends on jersey version, try to change
com.sun.jersey.config.property.packages
by
jersey.config.server.provider.packages
