Basic Controller Configuration Not working in Spring Boot - java

I am creating a sample project using Spring Boot and tried to map / with a simple String message. I have used #Controller annotation for this purpose. But for some reason the mapping is not working. I have also included #ComponentScan and #EnableWebMvc with no luck.
I have used maven spring-boot:run goal to run. Uploaded the project at https://github.com/tejact/SpringBasicsTreeHouse.
Here is the controller:
package Controller;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
#Component
#Controller
public class GifController {
#RequestMapping("/")
#ResponseBody
public String listAllGifs() {
return "Listing all gifs : Madhu";
}
}
The main application entry:
package com.teja;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
#EnableAutoConfiguration
#ComponentScan
#EnableWebMvc
public class AppConfig {
public static void main(String args[]) {
SpringApplication.run(AppConfig.class, args);
}
}
And Spring Boot logs:

By default #ComponentScan scans the the current package and all the sub packages.
In your case AppConfig class is in package com.teja and the GifController is in Controller package, so it's not scanned.
Move GifController to com.teja.controller for example, or any other sub package of com.teja and it will work.
Usually I keep the bootstraping class and all the configuration classes in package named <com|org|etc>.<myCompany>.<myProject> and then create the other packages as sub packages of this one.
Also you don't need both #Component and #Controller. Remove #Component -#Controller already inherits #Component.

I am using spring boot framework for my backend. Using mysql as database and tomcat as web server War file wont work

When i build it using mavan. the war file was generated, and I deployed it in tomcat but it wont work??
the war file doesnt work. If i try to click the link in tomcat. The web app says 404. So what is wrong with this. i attached my main class file, application properties and pom.xml file. If i build a war file. then i deployed in tomcat. My database doesnt create any tables I guess there is something wrong with my jdbc connection and my tomcat webapp. so please verify the code and gimme some answers

Spring Boot 404 on REST API calls only

Issue:
I'm working on a Spring-Boot Web Application that needs to be deployed on tomcat (WAR file). When running the application as Java (right click application.java file and run as Java in Eclipse) or running via mvnw.cmd spring-boot:run, everything works PERFECTLY (home page shows, all CRUD operations work).
When I export a WAR file and deploy to tomcat, my static web content and homepage still load fine, but any API calls return a 404 response.
This project was created using Spring Initializr. I've tried exporting via Eclipse war export, and mvnw.cmd package. Placed the WAR file in webapps directory on server and ran.
Directory structure:
Application file:
package com.blank.systemshare;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class SystemshareApplication {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
}
ServletInitializer:
package com.blank.systemshare;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

"message":"No message available",

}
Also, tomcat logs don't show anything useful.

Removing the ServletInitializer.java class and updating my application file to the following resolved the issue (extending SpringBootServletInitializer and overriding the configure method). Note that I tried this before, but built the application using both Eclipse and InteliJ. Both times the same issue still occurred. This final time I built using mvnw package and the WAR generated in the target directory worked.
package com.blank.systemshare;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class SystemshareApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(SystemshareApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SystemshareApplication.class);
}
}

Try server.servlet.context-path instead of server.servlet.contextPath.

Getting 404 error with spring boot application on localhost no exceptions in log

I am new to spring-boot and have created a dummy app which has one controller method.
The packaging type for the application is mentioned as jar in pom file.
On deployment there are no errors in logs.
But still after a successful build and deployment when i try to access my localhost from browser i get a 404 error.
Below are the things which i have already tried to resolve the issue :
1) Including my main class and controller class in same package.
2) Having my main class in root package and controller in sub package.
3) Defining #RestController on class as well as method.
4) Extending SpringBootServletInitializer in my main class
package com.test.controller;
#SpringBootApplication
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
**Controller class**
package com.test.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#RestController
public class TestController {
public final Logger logger = LoggerFactory.getLogger(TestController.class);
#RequestMapping(value = "/test", method = RequestMethod.GET)
public String test() {
logger.info("This is a test message to check if logback is working");
return "Hello World";
}
}
So as per the result i should have got a Hello World message on my web page but instead i got an 404 error.
Below is the log on service startup :

Spring-boot war application is running well on windows but not in ubuntu

I have a spring-boot war application that runs perfectly in windows and ios, then I tried to run it in linux. It did run and build normally but when I tried to open it via browser it returns invalid http responses in chrome and some undeciphered codes in Firefox. I used this pc to run another spring-boot projects and they work just fine. I'm using Maven 3.3.9 and Ubuntu 16.04.

I tried this on Ubuntu 17.10 but the same thing happened. Is there anything I can do to fix it? Thanks in advance
EDIT: I'm have openjdk8 in both version of ubuntu and windows. I'm not sure about the ios since its my friend's.
Here's how they look like when I tried to build it
in chromium & in firefox

I had this problem with spring-boot version 1.4.0.RELEASE and got resolved when switched to version 2.1.8.RELEASE

Web process failed to bind to $PORT within 90 seconds of launch

I am trying to deploy simple spring boot application with a single REST on heroku. The application is located here: application
My Procfile looks like this
web: java -jar target/java-cloud-sample-0.0.1-SNAPSHOT.jar -Dserver.port=$PORT
Build log on heroku looks like this

What is the problem? Why it cannot bind to $PORT?

To solve the problem I did two things.
Firstly, as it exceed 512 mb I set config var
JAVA_TOOL_OPTIONS = -Xmx300m
Second I changed slightly command line for starting the app
java $JAVA_OPTS -Dserver.port=$PORT -jar target/java-cloud-sample-0.0.1-SNAPSHOT.jar
And now it works!
