Servlet cannot be resolved in web.xml

Question

For some reason, the idea illuminates the dispatcher servlet, and when I run tomcat you get 404 error. I use spring mvc and Maven, here is a photo of web.xml Appreciate every answer =) WebApp / web.xml

<web-app 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_3_0.xsd" version="3.0"> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> 

Answer 1

The problem found, used tomcat7-maven-plugin with the compiled version of maven-compiler-plugin 1.8, after changing it to 1.7, the problem disappeared. However, are there any similar solutions for tomcat7-maven-plugin ? Because I did not find tomcat8-maven-plugin on the Internet

Thank you all for participating.

Answer 2

I had the same problem. It turned out that I used the old settings.xml file for the Maven user settings file. If anyone is having this problem, try using the Maven Template Users file.

Answer 3

You also need to add a servlet mapping, and then add spring-webmvc-version.jar to the classpath

 <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> 

Answer 4

Open the settings below:
Project Settings → Borders → Web → Deployment Descriptors

check the path here and make sure it is accessible. If not, click green + to add the path to the web module.

Answer 5

• Add spring mvc.jar file (if you use spring and mvc) to class libraries
• Verify that the [name] -sevlet.xml file is installed correctly. use the name inside the name "sevlet-name" "servlet name" in web.xml.

Answer 6

I am adding a path for the web module. Using Intellij, click on the project structure, and then select Facets. Deployment descriptors should probably be empty (this is not good), so add a path.
