Is it possible with Spring Boot to serve up JSPs with a JAR packaging?
I\'m familiar with the Spring Boot JSP sample application
However that example uses the WAR packaging. Is it possible to do the same with

If your springboot is building your project and running it in local server correctly then YES. What you need to do is to build the project using
mvn -U clean package. Then in target folder you have your runnable xxxx.jar . Now what you have to do is put your xxxx.jar file in the server or where you want along with thesrc/main/webapp/WEB-INF/jsp/*.jsp files in same hierarchy. then tryjava -jar xxxx.jarYour project will run with no issue.` . ├── src │ └── main │ └── webapp │ └── WEB-INF │ ├── jsp │ │ ├── default.jsp │ │ ├── help.jsp │ │ ├── index.jsp │ │ ├── insert.jsp │ │ ├── login.jsp │ │ ├── modify.jsp │ │ ├── search.jsp │ │ └── show.jsp │ └── web.xml ├── xxx.jar └── xxx.jar.original`java -jar xxx.jar

Please package your application as
warand execute asjar. This is documented at spring site.With Tomcat it should work if you use war packaging, i.e. an executable war will work (...). An executable jar will not work because of a hard coded file pattern in Tomcat.

- jsp sample
Deprecated, old answer
Yes, this is possible with Spring Boot.
Take look at this example: https://github.com/mariuszs/spring-boot-web-jsp-example.
For doing this use spring-boot-maven-plugin or gradle equivalent.
With this plugin jar is executable and can serve JSP files.
$ mvn package $ java -jar target/mymodule-0.0.1-SNAPSHOT.jaror just
$ mvn spring-boot:run讨论(0)Your best bet is to change the packaging type into war, and it should work without further changes.
As mentioned in on of the comments above, there are some limitations:
