Spring MVC Application Deployment on Tomcat - spring-mvc

I'm having an issue running a spring MVC application on a stand-alone tomcat server.
I am using Spring MVC (webmv)ver. 4.2.2, tomcat8.5 (8.5.33), and building with Maven.
The significant files in my project:

My Server is up and running at port: 9080.
I am deploying to tomcat from Eclipse (Photon), as follows:
right click --> run as --> Maven build --> on Goals: tomcat7:deploy
after successfully deploying, I opened the tomcat App Manager console, and verified the deployment:
No I would like to start the application, I hit the URL:
localhost:9080/home
Unfortunately I could not open the application. I am getting:
404 Not found: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Any advice greatly appreciated :)
Best,

spring MVC - mapping error [duplicate]

This question already has answers here:
Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"?
(13 answers)
Closed 5 years ago.
I found similar questions asked here but I tried those answers and here I am after spending a day. I dont know what is wrong here I am stuck with my first spring mvc application. If anyone can help me then that will be highly appreciated. I am getting error 404- Not found. Console error - "No mapping found for HTTP request with URI [/FirstSpringMVC/welcome] in DispatcherServlet with name 'mvc-dispatcher'"
Here is my entire code.

Well, have done below changes to your code to fix the 404 issue.
#Controller
public class HelloWorldController {
#RequestMapping(value = {"/welcome","/"}, method = RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView model = new ModelAndView("HelloWorldPage");
model.addObject("msg", "hello world");
return model;
}
}
It is almost same as yours except it answers to the requests received on root page("/"). I've just added it to directly test the homepage.
I don't know the reason, the combination of #Controller and <context:component-scan base-package="com.thomsontech.controller" /> weren't creating the helloWorldController bean. So, I had to explicitly create bean by adding <bean id="helloWorldController" class="com.thomsontech.controller.HelloWorldController"></bean> in mvc-dispatcher-servlet.xml file. I also removed <bean id="HandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> from the same file as I couldn't see that bean being used anywhere.
So, your final mvc-dispatcher-servlet.xml would be :
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.thomsontech.controller" />
<bean id="helloWorldController" class="com.thomsontech.controller.HelloWorldController"></bean>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
In your web.xml, have added <load-on-startup>1</load-on-startup> to </servlet> tag, so as to load mvc-dispatcher servlet on startup.
Also, you will have to upgrade of web-app version 2.3 as you are using jstl. JSTL doesn't works only with 2.4+ versions. However, this shouldn't stop you from testing 404 issue. ${msg} in HelloWorldPage jsp will not render "hello world" string returned by the HelloWorldController controller.
Your final web.xml would be :
<web-app>
<display-name>Archetype Created Web Application</display-name>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
After making these changes, do a cleanup of tomcat/jetty work directory followed by maven clean install and then run this app on the server.
Hope this helps and good luck!!

Spring MVC: No mapping found for HTTP request

I am making a simple Spring MVC Hello World project. However, I have this tiny bit of problem about the mapping of the jsp files in the URL. Whenever I call http://localhost:8080/SalesManagement/welcomeit returns the 404 Error. I have tried everything said in some of the same questions asked but I still can't make it run successfully. Here are my codes:
package com.salesmanagement.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloWorldController {
#RequestMapping("/welcome")
public ModelAndView helloWorld() {
String message = "<br><div style='text-align:center;'>"
+ "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CrunchifyHelloWorld.java **********</div><br><br>";
return new ModelAndView("welcome", "message", message);
}
}

The name of my project is SalesManagement.
I have my index.jsp inside the WebContent/WEB-INF folder while my welcome.jsp is inside the WebContent/WEB-INF/jsp folder.
I have tried adding the <mvc:annotation-driven /> tag and it's still not working.
Updating this comment this is what worked for me.

you can use this viewResolver.
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
use **spring 3.1.1** version jar file into pom.xml
and create welcome.jsp file and print ${message}

Note:But when I configure Emp class with (#component) it is working fine
#Component

} It is working fine
any one help me .
Your xml file is named spring-servlet.xml and your dispatcher servlet is servlet. But you explicitely declare in web.xml that you use an AnnotationConfigWebApplicationContext scanning package com.test, so :
spring-servlet.xml is ignored and no bean defined in it are used
#Component (or other spring annotations) classes are loaded as beans
As you have an explicit <context:component-scan base-package="com" /> in spring-servlet.xml, you should use the default application context (a XmlWebApplicationContext) and simply put in web.xml for the <servlet> bloc :
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
to use a XmlWebApplicationContext reading spring-servlet.xml (provided it lies under WEB-INF folder).
Edited your web.xml, try,
<?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"

(Spring MVC) Upload multipartfile method POST returns 404 error

I have a Spring application with an update file form:
<form class="form-inline" role="form" method="POST" enctype="multipart/form-data"
action="<c:url value="upload" />">
<div class="form-group">
<label class="control-label"> <spring:message code="file.to.upload"/> </label>
</div>
<div class="form-group">
<input type="file" name="file" id="file" class="btn btn-primary">
</div>
<div class="form-group">
<input
type="submit"
class="btn btn-primary"
value=<spring:message code="upload"/>>
</div>
</form>
But when I submit the form I get a 404 error which description says resource () not available. Note that it doesn't say "(/upload)", just an empty ().
My (not reached) controller is:
#Controller
#Scope(value = "session", proxyMode = ScopedProxyMode.INTERFACES)
public class WebController implements Serializable {
...
#RequestMapping(value="upload", method=RequestMethod.POST)
public String handleFileUpload(
#RequestParam("file") MultipartFile file, ModelMap model) throws CloneNotSupportedException {
System.out.println("Handling file");
... //never reaches here
return screen(model);
}

Thanks
The problem is because I'm using Spring Security with CSRF protection.
In this Spring doc there are solutions.
Finally I solved it including CSRF token in action as follows:
<form action="./upload?${_csrf.parameterName}=${_csrf.token}" method="post" enctype="multipart/form-data">
CSRF protection is enabled by default in the Java configuration. We can disable it if we need to:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable();
}

Getting Null pointer exception in using #PersistenceContext in Spring MVC with JPA

I am trying to create a simple Inventory based Project. I am new to Spring, I have followed the link http://www.objectdb.com/tutorial/jpa/eclipse/web to create the project. But I am unable to run the project as #PersistenceContext is not injecting Entity Manager in my code.
Please find below my code snippet
