By default, Spring Boot 1.5.10.RELEASE requires Java 7 and Spring Framework 4.3.14.RELEASE or above. You can use Spring Boot with Java 6 with some additional configuration. See Section 84.11, “How to use Java 6” for more details. Explicit build support is provided for Maven (3.2+), and Gradle 2 (2.9 or later) and 3.

Although you can use Spring Boot with Java 6 or 7, we generally recommend Java 8 if at all possible. |
The following embedded servlet containers are supported out of the box:
| Name | Servlet Version | Java Version |
|---|---|---|
Tomcat 8 | 3.1 | Java 7+ |
Tomcat 7 | 3.0 | Java 6+ |
Jetty 9.3 | 3.1 | Java 8+ |
Jetty 9.2 | 3.1 | Java 7+ |
Jetty 8 | 3.0 | Java 6+ |
Undertow 1.3 | 3.1 | Java 7+ |
You can also deploy Spring Boot applications to any Servlet 3.0+ compatible container.
