War not Working on External Tomcat after Spring boot upgrade to 2.6.6

Question

I have my pom.xml :

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
          </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
              <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>

            </dependency>

Also added :

<packaging>war</packaging>

Added contextpath in application.properties :

server.servlet.context-path=/admin

The name of war is also admin.war

I have also extended SpringBootServletInitializer in main class .

I upgraded the project from Spring Boot version 1.5.9 to 2.6.6 . When 1.5.9 version was used the war was deployed successfully in external tomcat. Now it shows as No mapping found for context Path with version upgrade. I am using tomcat version 9.0.64 with spring 2.6.6

Answer 1

Try using in properties

spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER
