"Sinkholes" springboot packaged into war, deployed to Tomcat, access 404

The pit is so deep that I can't breathe. as the friends said, I removed springboot embedded tomcat, and then rely on SERVLET-API, modify the start class to inherit Springbootservletinitializer, fight into a war into Tomcat but ..... Visit newspaper 404

this could be a split line . One, the war package released to Tomcat (this step has been completed, skipped) 1. Pom.xml

Remove inline Tomcat

'
     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId> spring-boot-starter-tomcat</artifactid>
        <scope>provided</scope><!--Open a comment when it's war Local development with inline Tomcat plus annotation-->
    </dependency>
'

Make War

'
    <packaging>war</packaging>
'

2. Start class

'
    @SpringBootApplication
    @ComponentScan (basepackages = "Com.yzker") Public
    class application extends Springbootservletinitializer {

        @Override
        protected Springapplicationbuilder Configure ( Springapplicationbuilder application) {return
            application.sources (application.class);
        }

        public static void Main (string[] args) {
            springapplication.run (application.class, args);
        }

`

MVN Clean Package put the war package under Tomcat and try it, if you report 404, refer to the following
Access address: Localhost:{tomcat port number}/renamed War package name/xxxx two, 404 Solutions

reasons for subsequent additions 1. Pom.xml

'
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId> spring-boot-legacy</artifactid>
        <version>1.1.0.RELEASE</version>
    </dependency >
'

2. Modify Web.xml

Copy the following code and modify the Com.yzker.test.application.Application for your own startup class

' <?xml version= "1.0" encoding= "UTF-8"?> <web-app version= "2.5" 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 htt P://java.sun.com/xml/ns/javaee/web-app_2_5.xsd "> <context-param> <param-name>contextconfiglo Cation</param-name> <param-value>com.yzker.test.application.Application</param-value> < /context-param> <listener> <listener-class>org.springframework.boot.legacy.context.web.sprin
