Is it possible with Spring Boot to serve up JSPs with a JAR packaging?
As @Andy Wilkinson said, there are limitations related to JSP. Please package your application as war and execute as jar. 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.
- 27.3.5 JSP limitations
- 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.war
(Note the extension of the artifact in the above command .war) or just
$ mvn spring-boot:run
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 the src/main/webapp/WEB-INF/jsp/ *.jsp files in same hierarchy.
then try java -jar xxxx.jar
Your project will run with no issue.

Thank You.
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:
http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-developing-web-applications.html#boot-features-jsp-limitations
27.3.5 JSP limitations
When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.
With Tomcat it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to a standard container (not limited to, but including Tomcat).
An executable jar will not work because of a hard coded file pattern in Tomcat.
With Jetty it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to any standard container.
Undertow does not support JSPs.
Creating a custom error.jsp page won’t override the default view for error handling, custom error pages should be used instead.

If for whatever reason, you can't deal with a war packaging, there's a hack. Full credit to this guy for doing it for an older version of spring-boot.
One way to do this is to personalize tomcat and add BOOT-INF/classes to tomcat's ResourceSet. In tomcat, all scanned resources are put into something called a ResourceSet. For example, the META-INF/resources of the application jar package in the servlet 3.0 specification is scanned and put into the ResourceSet.
Now we need to find a way to add the BOOT-INF/classes directory of the fat jar to the ResourceSet. We can do this through the tomcat LifecycleListener interface, in the Lifecycle.CONFIGURE_START_EVENT event, get the BOOT-INF/classes URL, and then add this URL to the WebResourceSet. A complete example is here, but you can do this like so:
import org.apache.catalina.Context;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.server.WebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@ConditionalOnProperty(name = "tomcat.staticResourceCustomizer.enabled", matchIfMissing = true)
public class TomcatConfiguration {
@Bean
public WebServerFactoryCustomizer<WebServerFactory> staticResourceCustomizer() {
return new WebServerFactoryCustomizer<WebServerFactory>() {
@Override
public void customize(WebServerFactory factory) {
if (factory instanceof TomcatServletWebServerFactory) {
((TomcatServletWebServerFactory) factory)
.addContextCustomizers(new org.springframework.boot.web.embedded.tomcat.TomcatContextCustomizer() {
@Override
public void customize(Context context) {
context.addLifecycleListener(new StaticResourceConfigurer(context));
}
});
}
}
};
}
}
And then use the LifecycleListener like so:
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.catalina.Context;
import org.apache.catalina.Lifecycle;
import org.apache.catalina.LifecycleEvent;
import org.apache.catalina.LifecycleListener;
import org.apache.catalina.WebResourceRoot.ResourceSetType;
import org.springframework.util.ResourceUtils;
public class StaticResourceConfigurer implements LifecycleListener {
private final Context context;
StaticResourceConfigurer(Context context) {
this.context = context;
}
@Override
public void lifecycleEvent(LifecycleEvent event) {
if (event.getType().equals(Lifecycle.CONFIGURE_START_EVENT)) {
URL location = this.getClass().getProtectionDomain().getCodeSource().getLocation();
if (ResourceUtils.isFileURL(location)) {
// when run as exploded directory
String rootFile = location.getFile();
if (rootFile.endsWith("/BOOT-INF/classes/")) {
rootFile = rootFile.substring(0, rootFile.length() - "/BOOT-INF/classes/".length() + 1);
}
if (!new File(rootFile, "META-INF" + File.separator + "resources").isDirectory()) {
return;
}
try {
location = new File(rootFile).toURI().toURL();
} catch (MalformedURLException e) {
throw new IllegalStateException("Can not add tomcat resources", e);
}
}
String locationStr = location.toString();
if (locationStr.endsWith("/BOOT-INF/classes!/")) {
// when run as fat jar
locationStr = locationStr.substring(0, locationStr.length() - "/BOOT-INF/classes!/".length() + 1);
try {
location = new URL(locationStr);
} catch (MalformedURLException e) {
throw new IllegalStateException("Can not add tomcat resources", e);
}
}
this.context.getResources().createWebResourceSet(ResourceSetType.RESOURCE_JAR, "/", location,
"/META-INF/resources");
}
}
}
