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
WARNING: Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json' not supported]
I think it has something to do with my pom.xml and my dependencies:

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

Spring MVC home directory 404 Error Intellij Idea

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.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...

I am running it with Spring Tool Suite( 3.6.0.RELEASE at windows) - I had similar problems with other projects from developers' blogs.
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.
