Resource Not Available Tomcat 404 error when using Spring Java Config - spring

Question

I am getting
"The requested resource (/SpringSecurity/welcome) is not available."
when using Spring Java Config
SpringInitializer.java
package com.security.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class SpringInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
// TODO Auto-generated method stub
return new Class[] { AppConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
// TODO Auto-generated method stub
return null;
}
#Override
protected String[] getServletMappings() {
// TODO Auto-generated method stub
return new String[] { "/" };
}
}
AppConfig.java
package com.security.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#EnableWebMvc
#Configuration
#ComponentScan({ "com.security" })
#Import({ SecurityConfig.class })
public class AppConfig {
#Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
HelloController class with Mappings
package com.security.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloController {
#RequestMapping(value = { "/", "/welcome**" }, method = RequestMethod.GET)
public ModelAndView welcomePage() {
ModelAndView model = new ModelAndView();
model.addObject("title", "Spring Security Hello World");
model.addObject("message", "This is welcome page!");
model.setViewName("hello");
return model;
}
}
My JSP files are available at "/WEB-INF/jsp/"
I am not getting any errors in console
I am using Tomcat 7
When i check my console i see
INFO: Mapped "{[/ || /welcome**],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView com.security.controller.HelloController.welcomePage()
so mapping seems to have been done. But still my tomcat server shows 404 error when i try to access using url : http://localhost:8081/SpringSecurity/welcome
I also tried "Clean Tomcat Working Directory". But i don't know the problem.

Answer 1

404 error is because the url you are triggering is not present or mapped. So kindly check the dispatcherservlet configuration you have done. Whether its mapped to /SpringSecurity or not. And also try giving /welcome alone in the controller instead of **.
