Spring MVC home directory 404 Error Intellij Idea

Spring MVC home directory 404 Error Intellij Idea - java

I'm studying Spring MVC, and I stuck almost at the start. I've followed the video about creating first MVC app but it's not working for me. I want to get main.jsp as start page, following the config but the page is not loading, I'm getting 404 all the time.
I've create a new Maven project. Then I've add Spring MVC framework support for the project, create web.xml and spring-mvc-demo-servlet for Spring configuration.
I've checked my project several times, but unsuccessful. Also, Ive checked similar topics but also wasn't able to found the solution.

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/")
public String showPage() {
return "main";
}

I think WebApplicationInitalizer is simplier for begining with Spring 5 and Intellij.
1) Add a WebMvcConfig class to your com.test.spring package like this :
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = { "com.test.spring"})
public class WebMvcConfig implements WebMvcConfigurer {
#Bean
public InternalResourceViewResolver resolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setViewClass(JstlView.class);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
2) Move your WEB-INF folder to a new folder src/main/webapp (mabe you'll have it as source folder by right cli clicking on it)
3) Remove your web.xml and spring-mvc-demo-servlet.xml files and all your old web folder
4) Add an application initializer
public class AppInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
Finally right click on AppInitializer class and then Run it...
Optionnally, you could add Tomcat to your Maven pom.xml and then run command mvn tomcat7:run :
<build>
<plugins>
...
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path>
</configuration>
</plugin>
<plugins>
<build>
Hope this will help you

Thank a lof for your answer Karbos, however I had to find the solution exactly for the sources I provided, cause otherwise I wouldn't be able to continie the course on Udemy...
I solve the issue, but the most creepy moment is that I have no idea how I made it. I added several changes to the project.
Changes in web.xml
<servlet>
<servlet-name>my-dispatcher-servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/dispatcher-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Changes in pom.xml
<packaging>war</packaging>
and some others I may didnt notice cause did it automaticly.
So the issue took one and a half day for me. Feel myself so retarded...

Spring MVC - Content type 'application/json' not supported

I'm writing an MVC project through Spring framework, not Spring Boot, in Eclipse Enterprise.
With Postman I'm sending a json object to my method:
#PutMapping(value = "/put_in_mail",
produces = MediaType.APPLICATION_JSON_VALUE,
consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Mailbox> putInMailBox(#RequestBody Mail mail) {
return service.putMailInInbox(mail);
}
But in Eclipse I'm getting this error:
Jul 11, 2022 5:08:10 PM org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver logException

As Sotirios Delimanolis mentioned, I missed a mvc:annotation tag in my -servlet.xml file and wrote something wrong about the schemaLocation, now json is supported with mvc.

Make sure the Model file contains all the required getters and setters for the data you are trying to send in JSON format.
If everything inside the Model file is fine do take a look at the link for a detailed solution

Maybe You have simple Spring MVC template that HAVE TO works ?
P.S it doesn't work with spring v. 3

EDIT: ///
OK, it works ... in Netbeans

Few changes that would be required in your code in web.xml please remove the
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value></param-value>
</init-param>
and change your "root-context.xml" and add the below line.
<mvc:annotation-driven />
<context:component-scan base-package="spring.blog.test"/>
and you have to change the your pom.xml and give the <outputDirectory>, <sourceDirectory>, <resources> under <build> in your pom.xml. it will tell from where to pickup the root-context.xml.

Intellij Idea - Could not autowire. No beans of 'ApplicationRepository' type found. less... (Ctrl+F1) Checks autowiring problems in a bean class

I am Java newbie.
I am making this tutorial (Spring MVC + Hibernate + Tomcat)
Everything goes fine till now. When I tried to make a ApplicationController I could not autowire ApplicationRepository.
I get this error message and 404 error code when I deploy application:
Could not autowire. No beans of 'ApplicationRepository' type found. less...

Ok talk is cheap.

EDIT #1
I have edited web.xml and added code:
<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">
<display-name>Spring MVC 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>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
But now I get Element listener-class is not allowed her from Intellij IDEA.
And my app even doesnt deploy.
EDIT #2
Well problem still occurs.
I renamed persistance.xml to persistence.xml.
Restarted Intellij idea and still getting this error.
Maybe this is a bug?
I will probably surrender with this Spring stuff, it's beyond me...

I followed the same tutorial and ran into the same code inspection warning (even if the application was working fine, the IDE was complaining). To make fix it, I added #Repository to my JpaRepository:
For your example:
package wzpweb;
import org.springframework.data.jpa.repository.JpaRepository;
#Repository
public interface ApplicationRepository extends JpaRepository<Application, Long> {
}

Rename your file persistance.xml to persistence.xml. The persistence.xml is, by default, the name of the file needed in the META-INF/ directory to define a persistence unit needed by your entityManagerFactory.
Here's a blog post explaining how Spring uses your custom interface implementing JpaRepository to generate an implementation class. I originally thought that you needed an implementation class for it, but that is not the case.
Small bug in the naming is your problem, given away by your first exception in the stack trace.
javax.persistence.PersistenceException: No Persistence provider for EntityManager named defaultPersistenceUnit

Add a context loader listener to your web.xml to read the Spring app context XML on startup.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/context/applicationContext.xml,/WEB-INF/context/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

removing the Spring facet (File->Project Structure)
Kill the project configuration in the facet of the relevant module configuration content, the IDEA is automatically identified. After the removal, the relevant error disappears. Does not affect compilation.

Similar issue come when you have created ObjectService and instantiated the same in the RestController and you havent annotated the ObjectServiceImpl with #Service.
