I am trying to deploy a RESTful Web Service built with Spring Boot into a Tomcat instance, with little success.
My software configuration is as follows: my computer is a Mac running OS X Yosemite 10.10.3, with Oracle Java JDK 8 1.8.0_45, Gradle 2.4 and Apache Tomcat 7.0.47. I use IntelliJ IDEA 14.1.4 as development platform.
I started by following this guide and I got a jar that initiates an embedded container which works as expected. Then I followed the document about converting a Spring Boot JAR Application to a WAR linked at the end of the other guide. I followed the instructions in Section 59.4 "Packaging executable jar and war files" and then those in the Section 74.1 "Create a deployable war file". According to the posts of a few other members of this site who were facing the same problem (here, here, here and here, just to name a few), I should be able now to create a create a WAR and deploy it on my Tomcat. Unfortunately, this is not the case.
The project contains the following 3 Java files: Application.java, Greeting.java and GreetingController.java. The first is as follows:
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
The second file contains the following:
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
And, finally, the latter file is:
package hello;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping("/hello")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(), String.format(template, name));
}
}
The project also contains the following build.gradle file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.4.RELEASE")
}
}
apply plugin: 'war'
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'
sourceCompatibility = 1.8
targetCompatibility = 1.8
war {
baseName = 'rest'
// version = '0.1.0'
}
repositories {
mavenLocal()
mavenCentral()
}
configurations {
providedRuntime
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
testCompile("junit:junit")
}
Now, if I run the task "gradle war", I generate a WAR file of about 8 Mb. I can successfully deploy it to my local Tomcat, but when I point my browser to http://localhost:8080/rest/hello?name=World I got a blank page rather than the page with the expected JSON. If I run the task "gradle build" or "gradle bootRepackage", I get both a JAR and a WAR and their original versions. I'm mentioning these commands because I haven't seen them anywhere and they might be useful to know. The original versions are both around 8 Mb in size, while the JAR and the WAR of 12 Mb. If I deploy both WARs, I get no error messages but, again, no results in the browser. Somebody here suggested that the web.xml could be missing, and in fact no WAR actually contained such a file. I am saying so because my Tomcat is not very recent and for some reason I thought Spring Boot had to automatically create a web.xml out of the code and annotations above.
As suggested by @dunni in the comments, here are my Tomcat log files. First of all, catalina.log:
giu 24, 2015 10:35:01 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /usr/local/apache-tomcat-7.0.47/webapps/rest.war
Then localhost.log:
giu 24, 2015 10:35:02 AM org.apache.catalina.core.ApplicationContext log
INFO: Spring WebApplicationInitializers detected on classpath: [org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@4dfaba52]
And finally manager.log:
giu 24, 2015 10:34:43 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
giu 24, 2015 10:34:44 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
giu 24, 2015 10:35:02 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
The above content is what I get after deploy the WAR. Nothing changes if I subsequently try to connect to http://localhost:8080/, http://localhost:8080/rest/, http://localhost:8080/rest/hello or http://localhost:8080/rest/hello?name=World.
What is going on? What am I missing? Can you please explain me what is the problem and what have I to do to successfully deploy this toy service on Tomcat? Many thanks in advance.
Since the above logs were not really helpful, I tried to restart the Tomcat daemon and I got something more meaningful. Now I have the following files: catalina.log, catalina.out, host-manager.log (empty), launchd.stderr (empty), launchd.stdout, localhost_access_log.txt (empty), localhost.log and manager.log (empty). catalina.log and catalina.out now contains the following:

launchd.stdout contains:

And localhost.log contains:

If I try to consume the Web Service, localhost_access_log.txt is updated with:
217.20.22.194 - - [24/Jun/2015:11:23:16 +0200] "GET / HTTP/1.1" 200 11444

Since I have the feeling that these logs are not really helpful, I tried to shutdown and startup Tomcat. In this case I find something interesting in catalina.log and catalina.out. The former:

By looking at these logs, I have the feeling that something is failing in the auto-magical process of Spring but unfortunately I don't know what and how to fix it. Any help?
