Springboot project into a war package, deployed to Tomcat, normal start access error 404

Objective:

Project description, this project is a MAVEN multi-module project, module Project: All (parent module), Util (Common tool Class), DAO (Entity class, Business class, Mapper, Mapper.xml); Business (service service); App-root (is a parent project that contains backend, PC, Mobile, schedule) ...

Structure diagram:

All +--App-root +-   -app-backend   --app-pc   --app-Mobile   --app-  Schedule-- Business-- DAO--Util

Error:

Error description, I put the App-backend project with MAVEN into a war package, uploaded to the production of Tomcat, Tomcat can start normally. However, the visit was reported at 404.

Workaround:

　　1. on the startup class of the App-backend project, add the following code:

@Override protected Springapplicationbuilder Configure (Springapplicationbuilder application) {    return Application.sources (appbackendapplication.  Class);}

2, in the App-backend project Pom.xml, modify the following dependencies.

<Dependency>   <groupId>Org.springframework.boot</groupId>   <Artifactid>Spring-boot-starter-web</Artifactid>   <!--Ignore inline tomcat and package deployment to Tomcat. Note * local run time to ignore this paragraph to introduce a comment out, or the project can not start -   <Exclusions>      <exclusion>         <groupId>Org.springframework.boot</groupId>         <Artifactid>Spring-boot-starter-tomcat</Artifactid>      </exclusion>   </Exclusions></Dependency>

Summarize:

I passed the above two steps and the problem was solved. The reason for the error is that the Springboot embedded Tomcat is in conflict with our Tomcat container. I hope I can help the people who have read this article.
