Using Spring Boot Web Application with Pivotal TC Server

Question

I refactored my project as a Spring Boot application from inside Spring Tool Suite. All the documentation shows how to create a self contained application with an embedded T

Answer 1

You can deploy a Spring Boot application to tc Server in the same way that you'd deploy it to any other standalone servlet container. There are three changes that you need to make:

1. Extend SpringBootServletInitializer so that the container will bootstrap your application correctly:

   @Configuration
   @EnableAutoConfiguration
   @ComponentScan
   public class Application extends SpringBootServletInitializer {
   
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
           return application.sources(Application.class);
       }
   }
   

2. Convert the project to use war packaging. Maven example:

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
       <!-- ... -->
       <packaging>war</packaging>
       <!-- ... -->
   </project>
   

3. Mark your spring-boot-starter-tomcat dependency as provided so that embedded Tomcat doesn't conflict with the classes in tc Server. Maven example:

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

I'm not aware of any differences between the class-reloading capabilities of Tomcat and tc Server. Perhaps you have Spring Loaded configured in your tc Server instance? If so, you can use it with Spring Boot too.
