I am trying to build a SpringBoot application.

 import org.springframework.boot.autoconfigure.SpringBootAppli         


        

Answer 1

For me, upgrading javax.servlet-api to 4.0.1 did the trick:

<dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> </dependency>

Answer 2

Looks like you have an incompatible version of Servlet API in ur classpath. This could have been as a dependencies to Jersey jars. Try pulling jersey starter from Spring boot starters.

org.springframework.boot : spring-boot-starter-jersey

This will bring the right version into your classpath.

Answer 3

My guess is you have to use the default ServletInitializer class that is provided within the Spring Boot Project template of Eclipse.

//SpringBootApplication.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootApplication.class, args);
    }
}

//ServletInitializer.java
public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootApplication.class);
    }

}

If you are not using ServletInitializer class as specified in Spring Boot Starter Project template, try to extend SpringBootServletInitializer from your App class

public class App extends SpringBootServletInitializer

I solved this problem using tomcat configuration in pom.xml

First go to tomcat folder and open cmd in bin my path is :

C:\Program Files\Apache Software Foundation\Tomcat 8.5\bin>

get tomcat version using this command

C:\Program Files\Apache Software Foundation\Tomcat 8.5\bin>catalina.sh version

After this add this in pom.xml

<properties>
        <java.version>1.8</java.version>
        <tomcat.version>8.5.43</tomcat.version>
</properties>

I had the same issue, After commenting out the below it was fixed. One of the follwoing dependency was the culprit.

    <!--  dependency>
    <groupId>me.fhir</groupId>
    <artifactId>fhir</artifactId>
    <version>0.12.0-RELEASE</version>
</dependency-->
<!--  dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.8</version>
</dependency-->
<!-- dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.8.8</version>
</dependency-->
