Spring Bootを起動させてもすぐにShutdownしてしまう場合にやること

こちらの回答の通りにやったらうまくいった。

The only possible explanation i can think of is that tomcat embedded jar is not included in the dependencies/jar. Since you have already defined "spring-boot-starter-web" dependency, it should have transitively pulled the embedded tomcat dependencies as well. But somehow it is excluded.

Things to try out.

Execute "mvn dependency:tree" and check whether the tomcat dependencies exist and in "compile" scope
Change the spring boot starter version to 1.4.0.RELEASE.

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.0.RELEASE</version>
    </parent>

最初、1.5.0.RELEASEなんてしてたのを、1.4.0に変更。 Run as…のRun configurationでMaven Build で、Goalsのところに「dependency:tree」を書いてRun
