I added META-INF folder with context.xml contain

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/SpringGradleDemo"/>

SpringGradleDemo is my project name and it work. My servlet-mapping is "/" I read it here https://tomcat.apache.org/tomcat-5.5-doc/config/context.html

Answer 4

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

Answer 5

With the web.xml configured they way you have in the question, in particular:

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

ALL requests being made to your web app will be directed to the DispatcherServlet. This includes requests like /tasklist/, /tasklist/some-thing.html, /tasklist/WEB-INF/views/index.jsp.

Because of this, when your controller returns a view that points to a .jsp, instead of allowing your server container to service the request, the DispatcherServlet jumps in and starts looking for a controller that can service this request, it doesn't find any and hence the 404.

The simplest way to solve is to have your servlet url mapping as follows:

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Notice the missing *. This tells the container that any request that does not have a path info in it (urls without a .xxx at the end), should be sent to the DispatcherServlet. With this configuration, when a xxx.jsp request is received, the DispatcherServlet is not consulted, and your servlet container's default servlet will service the request and present the jsp as expected.

Hope this helps, I realize your earlier comments state that the problem has been resolved, but the solution CAN NOT be just adding method=RequestMethod.GET to the RequestMethod.
