Spring #Value Annotation Not Resolving - java

I realize this question has been asked countless times, but none of the solutions appear to be working for my situation.
I have a basic Spring-WS app I'm putting together with a single servlet context. I can see that both the #Component annotated class and the properties file are both getting picked up on startup as shown by the logs below. However, my #Value annotated String is coming back as null.
Does anyone see anything wrong with the way I've set this up? Please feel free to ask for any additional information I may have left out.
Going forward, what are the best methods I can use to investigate issues like this I encounter in the future?

You aren't using a Spring managed bean. You are creating an object yourself.
MailServerUserController userController = new TelnetMailServerUserController();
In this case, Spring is not involved in processing the #Value annotated field (or anything else for that matter).
Instead, get the bean from the context, inject it.
#Autowired
private MailServerUserController userController;

Why do I always have this when starting a webmvc project? No mapping found for HTTP request?

This problem have been driving me crazy for a week now. I have been searching around solutions but cannot find it. I have tried starting new project and it keeps happening to me. I do not think its my code error. I think it has to do with my Eclipse configuration.
I am using JDK1.8, latest Eclipse IDE, and tomcat 8.5.
If anyone can help me solve this problem, then u guys will make my whole week.
Please help me figure out the problem... PLEASE!

EDIT:
I have made an edit to my HelloController.java on #RequestMapping from /hello to /
The code still does not work.
package com.tutorialspoint;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;
#Controller
#RequestMapping("/")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}

I didn't test it but you may try to adding the following to your web.xml file.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/HelloWeb-servlet.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Also, based on your controller the path would be /HelloWeb/hello

You are defining your web.xml for Tomcat 5, Servlet 2.3.
Try switching to a newer version, at least 2.5, usign XSD instead of DTD
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
Also, don't forget to declare a <mvc:annotation-driven /> member in your XML configuration.
And generally speaking, perhaps it should be better to start using a more up to date Spring MVC tutorial since the Spring version you're using (3.2) was released like 7 years ago?

I have done two things and it works fine in my side.
First,add <mvc:annotation-driven/> in HelloWeb-servlet.xml
Then,enable EL expression in hello.jsp with the following code:
<%# page language="java" contentType="text/html; charset=UTF-8"%>
<%# page isELIgnored="false" %><!-- add this line to enable ex expression -->
After doing this, it can run success in my side,and the running result is as below:
If it still do not work in your side,you need to clean and rebuild it,or recreat it again.
I have upload my source code into Google Drive,you can check it if necessary(note the project name is utest but the build path is /HelloWeb)

You HomeController seems to be in com.learnspring.web.config and that is not being package scanned. I guess your OffersController is in the same package. Else you need to add that to package scanning as well. Hope this resolves the issue.So try changing the below
<context:component-scan base-package="com.learnspring.test">
</context:component-scan>
to
<context:component-scan base-package="com.learnspring.web.config">
</context:component-scan>

No mapping found for HTTP request with URI [/offers/] in DispatcherServlet with name 'offers'

I am learning spring and stuck on this error. I have clean the project, ran maven build which runs build success and refreshed the target but I have still had no luck. Here is the code:

It looks like you're trying to register your controller on web.xml by doing:
<servlet-mapping>
<servlet-name>offers</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
In my opinion you don't need to do that. You can get away with just registering the RequestDispatcher and then as Patrick LC mentioned, have
<context:component-scan base-package="com.learnspring.controller">
take care of scanning your code for controllers to register. Then, it's a matter of setting the request mapping to whatever you want to use. Below I use home.spr, where spr stands for spring, but that's just a convention I use; the important thing is that whatever you choose needs to be declared on the web.xml as below:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.spr</url-pattern>
</servlet-mapping>
Then on your controller do:
#RequestMapping("/orders/home.spr")
public String getHome(Model model) {
List<Offer> offers = offersService.getCurrent();
model.addAttribute("offers", offers);
return "home";
}
Oh...and you might want to try spring.io, it's a bit simpler to work with.

No error in apache but I get a 404 error

I have been at this for a day now and cannot understand why it is not working. I followed a tutorial, read the spring documentation and still do not understand, even better there are on errors to go off of.

Final notes:
Use Spring webmvc jar. checkpom.xml all you need is this.
Add to offers-servlet.xml . Check below notes for
-Don't use run on server inside eclipse and make the request to http://localhost:8080/offers/ from a browser.
The caveat to overriding the "/" Servlet mapping is that the
RequestDispatcher for the default Servlet must be retrieved by name
rather than by path. The DefaultServletHttpRequestHandler will attempt
to auto-detect the default Servlet for the container at startup time,
using a list of known names for most of the major Servlet containers
(including Tomcat, Jetty, GlassFish, JBoss, Resin, WebLogic, and
WebSphere).

Cannot Resolve Views inside WEB-INF/ folders using the jsp filename as RequestMapping value

Ok this is always a problem for spring beginners, there could be tons of similar problems out there, but every time I type this issue, I always end up reading indirect solutions which I cannot understand, just like what the title said, I cannot resolve views(jsp) inside my WEB-INF/views folder, if i map the page using the file name.
Update: I've been searching extensively with a noHandlerFound/NoMapping Found for a URI problem, I just learned that the controller class name will be resolved by ControllerClassNameHandlerMapping removing the controller and lowercasing the non-controller name and it will be used as the url,
but I CANT still get to load my very simple page in start-up, and no matter where I search there are always tutorials that gives the same example, it does not work. please I need help here.. :(

Everytime I run this very simple web application on start,
The servlet resolves the view and display the content of the page by this URL
http://localhost:8080/ProductsHome/
but when I refresh the page, it results into a 404 error
and I need to manually type the file name of the jsp to resolve the view
http://localhost:8080/ProductsHome/productsHome
This is the kind of code I always see in the tutorials I'm reading especially spring-recipe book, but I cannot make it work the way it was said in the book, I expect that on the first start-up the dispatcher-servlet will resolve the views and displaying the page with this URL below
how can I make this work? any help would be greatly appreciated.
http://localhost:8080/ProductsHome/productsHome/home
here is the server log I get so far, I'm currently searching what I need to add to eclipse to show any error

I thing the controller should be
#Controller
#RequestMapping(value = "/welcome")
public class WelcomeController {
#RequestMapping(method = RequestMethod.GET)
public ModelAndView welcome() {
return new ModelAndView("productsHome");
}
put the welcome-file-list in web.xml
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
in the file index.jsp , file index.jsp in the WEB-INF directory
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("welcome"); %>
change the servlet-mapping
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
make sure that productsHome.jsp is in the /WEB-INF/views/ directory

The problem is with the servlet mapping.
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
