How to deploy spring boot web application on tomcat server

Question

I have created spring boot web application, but I am unable to deploy spring boot web application WAR file on tomcat and I am able to run it as java application. How to run

Answer 1

Here are two good documentations on how to deploy the Spring Boot App as a war file.

You can follow this spring boot howto-traditional-deployment documentation -

Steps according to this documentation -

1. You update your application’s main class to extend SpringBootServletInitializer.

2. The next step is to update your build configuration so that your project produces a war file rather than a jar file. war

3. Mark the embedded servlet container dependency as provided.

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

and one more way -

See this spring io documentation which outlines how to deploy the spring boot app to an application server.

Steps -

1. Change jar packaging to war.

2. Comment out the declaration of the spring-boot-maven-plugin plugin in your pom.xml

3. Add a web entry point into your application by extending SpringBootServletInitializer and override the configure method

4. Remove the spring-boot-starter-tomcat dependency and modfiy your spring-boot-starter-web dependency to

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

In your pom.xml, remove spring-beans and spring-webmvc dependencies. The spring-boot-starter-web dependency will include those dependecies.
