java.lang.ClassNotFoundException: javax.servlet.Filter

java.lang.ClassNotFoundException: javax.servlet.Filter:有两个原因：（1）在maven中的作用域，不能是provided，需要是compile就是默认的scope（2）spring-boot-starter-tomcat的版本bug，换个新的或旧的版本试试

I Started a new project with Spring Boot 1.2.3. I'm getting error

java.lang.NoClassDefFoundError: javax/servlet/Filter

Gradle Dependencies:

for the maven users, comment the scope provided in the following dependency:

org.springframework.boot spring-boot-starter-tomcat

UPDATE

As feed.me mentioned you have to uncomment the provided part depending on what kind of app you are deploying.

Here is a useful link with the details: http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging

It's important to make this dependency "provided" again before building a war file! Otherwise the war file will crash when it gets deployed (happend to me with tomcat)

Springboot project runs fine when running from terminal using command mvn spring-boot:run

Running from Intellij is when I was getting an exception. I changed the spring-boot-starter-tomcat in pom.xml to an older version and it runs without any exception. I think the issue was with compatibly for latest maven embed tomcat 1.2.5.RELEASE.

Now I am using below in my pom.xml

org.springframework.boot spring-boot-starter-tomcat 1.2.4.RELEASE
