it doesn't have an embedded server like Tomcat in classpath. add it and it will fix the issue
for MAVEN add this dependancy in pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
for Gradle (build.gradle) add
dependencies {
compile 'org.springframework.boot:spring-boot-starter-web'
}
You need to add this dependency to your pom.xml.
After that it should work.

The problem reproduces when I run tests from IDE and mvn.
How to avoid problem with tests?
I found solution, it needs to add next properties to each test:
#SpringBootTest(properties = {
InteractiveShellApplicationRunner.SPRING_SHELL_INTERACTIVE_ENABLED + "=false",
ScriptShellApplicationRunner.SPRING_SHELL_SCRIPT_ENABLED + "=false"
})
In Spring Shell 2:
#SpringBootTest(properties = "spring.shell.interactive.enabled=false")
I imported a springcloud demo , version Finchley.SR2, after starting the application,I couldn't visit Eureka register center page,status 404.
I don't have and controller yet,Only a #SpringBootApplication
Same problem on eclipse and Idea
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Wed Apr 17 10:46:08 CST 2019
There was an unexpected error (type=Not Found, status=404).
No message available
If I use version Finchley.SR1 with dependency jersey-bundle 1.19, everything is normal.

Here is my application.yml:
server:

eureka:
client:
register-with-eureka: false
fetch-registry: false
Here is my Application class:
#SpringBootApplication
#EnableEurekaServer
public class HubRegisterCenterApplication {
public static void main(String[] args) {
SpringApplication.run(HubRegisterCenterApplication.class, args);
}
}
Problem solved.
use mvn install command,and I found that there is some problems in maven dependency jar file. delete them and re-download,problem solved
Use application.properties file instead of application.yml file.
like
spring.application.name=cart-service
server.port=8082
It worked for me.
I am really new with spring boot, so I started with some tutorials to create a simple Rest example (my final goal is to integrate it with mongodb, but I need to start!).
I created a new project on IntelliJ with Spring Initializr and choosed Web and Mongodb as features.
Then I added only a class,
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class HelloController {
#RequestMapping("/")
public String index() {
return "Greetings from Spring Boot!";
}
}
When I run the project, the console is

But when I go on localhost:8080/ I get 404 error. What did I do wrong in my helloworld? Is there anything that should I make before running the application?
You need to either
Fix the project structure in order to place the Application Entry Point (TestApplication in this case) in the base package (see image below).
Or use #ComponentScan like this (not recommended):
#SpringBootApplication
#ComponentScan("prova") // add the names of the packages where the controllers, services, repositories, etc, are going to be stored.
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
Your package structure is wrong:
prova.HelloController
test.test.TestApplication
The HelloController must be on the same level or below TestApplication.
You can do it 2 ways.
1.(preferable) Your controller package naming should be test.test.prova
i.e. Your springboot application should follow the package naming structure of Main class.
e.g. If your Main class has package name = com.test, so the controller package name should be com.test.controller
Another way is adding #ComponentScan to your Main class.
e.g.#SpringBootApplication
#ComponentScan("prova")
Has anyone experienced a very slow startup time for SpringBoot 2.0 on MacOS Sierra?

Any ideas?
Ok, StackOverflow is making me add "more details". Not sure what else to add here.
Ok, figured it out. It had nothing to do with Spring Boot 2.0. Just happened to coincide with that upgrade.
The real answer is from this StackOverflow:
Maven with Surefire (TestNG) is slow after update to MacOS Sierra
Set it like this
open your terminal and run hostname
$ hostname
xxx.local
modify the host config in file /etc/hosts
127.0.0.1 localhost xxx.local
::1 localhost xxx.local
Using Spring Boot 2 for an IoT application, I notice that the startup time for Spring is disproportionally slow. The platform is a Raspberry PI 2B - of course, this is going to be significantly slower than a PC. For normal code execution I measure a 20x to 50x difference.
Spring boot startup time on my PC (Win10 x64): 5 seconds
Spring boot startup time on the PI (Ubuntu Server, ARM java in docker running a jar): 11 minutes
If I use the highest factor I've ever measured (50x), I would expect to see a startup time of less than half of the current state. So far, I tried:
Excluding dependencies from auto configuration (now minimal with only only spring-boot-starter-web, kotlin, undertow, webflux, reactor and kafka)
Logging on DEBUG to see what was happening during quiet periods (mostly beans being set up, nothing suspicious, though some beans take several seconds to load)
Different docker image for Java on ARM (no effect)
CPU is consistently at 100%, memory is around 20% and there is plenty of disk space
My preliminary conclusion is that loading beans eats all the CPU cycles. I imagine that initializing a bean should not take several seconds, but it does. What could be the bottleneck here? Can I get Spring to load faster in any way?
Here is the first part of the output from a PC:

Update:
For those reading this, I moved back to OpenJDK in 2019 due to the new Oracle policies. What I noticed is that OpenJDK has made significant performance improvements recently. If you use OpenJDK 11 and above, it has similar performance to Oracle JDK and you can easily configure its language level to work with Java 8 code. That said, if this does not work for you, try the below.
I moved to a new image: Oracle JDK instead of OpenJDK as #snodnipper suggested.
There were several things I had to do including installing a more recent version of Java 8 than the one available in the standard repository. This is the Dockerfile that ended up working for me, and now the application starts in 2 minutes.
