Tomcat Server Won't Start When Following Spring MVC Guide

Time：10-08

I'm trying to create a Spring MVC hello world api (without Spring Boot), and I have been tasked with doing it using Spring 4.4 or above. I found a guide that shows how to basically do it:

https://frugalisminds.com/spring-mvc-basic-setup-hello-world/

However, when I try to run the Tomcat server, it says that it fails to startnot start for me, and I do not know how to fix it.

The exact error is the following:

From what I've read, there seems to be a few potential causes for this, such as my web.xml having a typo, but the thing is, I actually do have a working version using Spring 4.0 (where I followed this guide: https://www.programming-free.com/2014/01/spring-mvc-40-restful-web-services.html ). Comparing the two web.xml files, they are nearly exactly the same, except for a welcome file list and a difference between javaee/web-app_3_1.xsd and javaee/web-app_2_5.xsd. I also changed my controller to be a simple "Hello [name]" format, like in the previous guide I followed, which I wouldn't think would lead to a change.

Any help would be greatly appreciate on how to take care of this error.

CodePudding user response：

The error you are looking for is this maybe :

Caused by: java.lang.IllegalArgumentException: More than one fragment with the name [spring_web] was found. This is not legal with relative ordering. See section 8.2.2 2c of the Servlet specification for details. Consider using absolute ordering.

you need to :

add <absolute-ordering /> tag to your web.xml just under the <display-name> tag. should work.

CodePudding user response：

If you are using XML just add <absolute-ordering />. If you are using all Java config (no XML), you can’t use the <absolute-ordering /> trick. For all Java config, this issue can be resolved by deleting the file WEB-INF/lib/spring-web-5.1.5.RELEASE-sources.jar Be sure to update with the appropriate version number for your Spring distribution.
