I'm new to using Spring, and I'm going through the accessing-data-with-MySQL tutorial here. I'm using Eclipse, and when I download all the code for the project, and then run the project as a Spring Boot App, I get the error:
APPLICATION FAILED TO START
Description:
Field userRepository in hello.MainController required a bean of type 'hello.UserRepository' that could not be found.
Action:
Consider defining a bean of type 'hello.UserRepository' in your configuration.
Again, this is the code directly from the tutorial. Anybody have any idea what's going on?
Thanks!

I was able to fix this problem by clearing my maven cache. I did this by manually deleting my:
C:\Users\username\ .m2
folder and then doing a clean install. What the problem was, how it developed, and what changed to fix it I/we may never know. But, things seem to be working again.
Thanks to all who helped!
Have you registered a repository with type UserRepository? Check if you sign the repository with a #Repository annotation.
Download project from git gs-accessing-data-mysql-master
Extract the file to your disk
Open Eclipse
Click File > Import > Existing Maven Projects > Next
Click Browse and select the gs-accessing-data-mysql-master folder that is on your disk and Next
Select both pom.xml and Finish
Open gs-mysql-data project that has been imported
Right click on Application.java and run as Java Application or Spring Boot Application
Make sure that UserRepository interface extends from CrudRepository, like this:
package hello;
import org.springframework.data.repository.CrudRepository;
import hello.User;
// This will be AUTO IMPLEMENTED by Spring into a Bean called userRepository
// CRUD refers Create, Read, Update, Delete
public interface UserRepository extends CrudRepository<User, Long> {
}

Update your application's configuration in Spring Boot error when I am running a Spring Boot Application.
The maven is built successfully, but still the error persists.
What should I do to change overcome this error?

Description:
Binding to target [Bindable#6bff19ff type = java.lang.String, value = 'provided', annotations = array<Annotation>[[empty]]] failed:
Property: spring.datasource.password
Value: ${password}
Origin: class path resource [application.properties]:7:28
Reason: Could not resolve placeholder 'password' in value "${password}"
Action:
Update your application's configuration
You have to turn on filtering for your maven resources plugin. You have to add a <filtering> tag to your POM and set it to true.
The ${password} variable possibly needs to be replaced with the real password by maven, during the "process resources" phase
For further info see:
https://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html
It looks like you have not declared the property 'password' (or there's something wrong with it's declaration) that you're trying to use in 'spring.datasource.password' property.
It's hard to tell, though, without seeing the whole properties file.
The error is because your application can't find the env variable password. If this problem only happens on you local machine, simply specify a default value when the env var is not present. Like this:
spring.datasource.password: ${password:local-password}
(Change local-password to the real password of your local database.)
If it happens in your test or prod environment, you have to inject it into your server's environment variables, or contact the DevOps guy to help you do that.
In my case removing below from pom.xml fixed the issue
<resources>
<resource>
<filtering>true</filtering>
<directory>${project.basedir}/src/main/resources/</directory>
<targetPath>${project.build.directory}/config/</targetPath>
<includes>
<include>application.properties</include>
</includes>
</resource>

Your controller is not scanned by the default component scan that Spring Boot provides. By default Spring boot starts from the package that contains the "main" class - the one annotated with #SpringBootApplication and also scans all of it's sub packages.
Your main class is in package com.template; but the controller is in package controller;. Move the controller in a package named package com.template.controller;
Since you are using FreeMarker Template with spring boot, I would suggest you to move your welcome.ftl template from this location src/webapp/welcome.ftl to this src/main/resources/templates/welcome.ftl and then restart your application and hit http://localhost:8080/welcome

Description:
Cannot determine embedded database driver class for database type NONE
Action:
If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
The reason for the exception is
Cannot determine embedded database driver class for database type NONE.
If you want an embedded database please put a supported one on the
classpath. If you have database settings to be loaded from a particular
profile you may need to active it (no profiles are currently active).
Spring autoconfiguration is creating only one DataSource and expects properties as
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring boot reference
You do not set these properties, so spring tries to create a datasource without url, which leads to the exception.
You need to create additional DataSources yourself, you may find this post helpfull.
I got a Spring Boot app. It's running as such:
#SpringBootApplication
public class MyBooty implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(MyBooty.class, args);
}
public void run(String... args) throws Exception {
SomeClass someClass = new SomeClass(...);
someClass.doStuff();
System.out.println("Why Am I appearing Before \"Started In\" log line?");
}
Does what I need. But I noticed this line in the output: Started MyBooty in 17.594 seconds (JVM running for 18.206), which was printed after some of my console output.
This made me think my code was actually executing before the app was actually initialized. So I did some research found this blog post and then set up a new class as such:
#Component
public class ApplicationStartup implements ApplicationListener<ApplicationReadyEvent>{
public void onApplicationEvent(ApplicationReadyEvent event) {
SomeClass someClass = new SomeClass(...);
SomeClass.doStuff();
return;
}
}
Which supposedly executes after after application startup. Well, I still see the Started app in... output after my output again.
So, concept check. Are things working as intended and I'm just being naive? Or is there maybe something missing? If someone could knowledge share on the topic that would be appreciated.
Again, my code runs and does exactly what I need it to, but I just want to make sure I'm using/taking advantage of Spring Boot properly.
In case it's unclear what I'm asking, I'm asking Why does the "Started App in X seconds" message appear after my output? I ask this because I simply found it confusing that it said the app was started after my business code had ALREADY ran. This question is a conceptual question about how spring boot starts up.
Edit: Console Output

You class is annotated with #SpringBootApplication, which makes it automatically register as a Spring Bean.
The SpringApplication run(Object source, String... args) method you are calling ends up calling run(String... args).
The run() method calls the afterRefresh() method right before it logs the "Started ..." message, and afterRefresh() will call the run() method of any registered ApplicationRunner and CommandLineRunner beans.
Or, as the documentation says it:
If you need to run some specific code once the SpringApplication has started, you can implement the ApplicationRunner or CommandLineRunner interfaces. Both interfaces work in the same way and offer a single run method which will be called just before SpringApplication.run(…) completes.
I would like to set up a dev environment on my Windows 7 machine so i can create a spring-boot application. However, i'm having a hard time installing Spring-boot on windows.
This is what i have done so far:
-Downloaded spring-boot CLI zip package and unzipped in C drive
-JAVA_HOME variable set to c:\Program Files (x86)\Java\jdk1.6.0_14
-SPRING_HOME variable set to C:\spring-1.3.0.BUILD-SNAPSHOT
-Added SPRING_HOME/bin to PATH environment variable
It says to add symlink to auto-completion script but i do not know how to do that. Not surprisingly when i test installation with "spring --version" command, it fails.
Anybody has done this before?
Thanks!
Instructions for setup are bit misleading for path setup.
For Windows, Environment variables section, need use %SPRING_HOME%\bin referencing in place of SPRING_HOME/bin for the system to pick up SPRING_HOME environment variable.
Where SPRING_HOME is an environment variable for specifying path to the spring boot directory.
E.g. :- C:\Program Files\Spring\spring-1.2.7.RELEASE
Note: bin folder is not included in the SPRING_HOME.
I was able to get it up, here are screen grabs of process.
Alternatively you can have the path setup directly without SPRING_HOME, just append the environment variable path with directory path of your "spring.bat" file C:\Program Files\Spring\spring-1.2.7.RELEASE\bin;.
Windows looks in the current directory before searching the path. So, when you're in the bin directory it sees the spring command there and does not look at the path.
1.MANUALLY INSTALLING THE SPRING BOOT CLI
spring-boot-cli-2.0.0.M1-bin.zip is installed.
2.Extract spring-boot-cli-2.0.0.M1-bin.zip.
3.After spring-2.0.0.M1 extractd.
4. Direct command prompt
