Problem with annotation #Autowired. how to decide?

There is a code:
package com.example.sweater3.domain;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Message {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private String text;
private String tag;
public Message() {
}
public Message(String text, String tag) {
this.text = text;
this.tag = tag;
}
public void setText(String text) {
this.text = text;
}
public String getText() {
return text;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getTag() {
return tag;
}
public void setTag(String tag) {
this.tag = tag;
}
}
_
package com.example.sweater3.repos;
import com.example.sweater3.domain.Message;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import java.util.List;
#Repository
public interface MessageRepo extends CrudRepository<Message, Long> {
List<Message> findByTag(String tag);
}
__
package com.example.sweater3;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

package com.example.sweater3;
import com.example.sweater3.repos.MessageRepo;

Description:
Field messageRepo in com.example.sweater3.GreetingController required a bean of type 'com.example.sweater3.repos.MessageRepo' that could not be found.
Action:
Consider defining a bean of type 'com.example.sweater3.repos.MessageRepo' in your configuration.
If I comment on the #Autowired annotation everything works.
What is the problem and how to solve?
p.s. The code is as simplified as possible, since I removed extra pieces so that they would not interfere with reading the code and clutter up the review.
upd:
Response to comments:

Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

You must enable repositories in your application :
#SpringBootApplication
#EnableJpaRepositories
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Also make sure that you add :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
UPDATE :
You must configure your database connection and driver. Example with H2 (in memory database)
Add new dependency:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
In application.properties add:
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration'

I am trying to develop a sample spring boot application that has spring JPA and Hibernate implementation. While I managed to get my setup complete, I am getting the following error while running the application.
Error creating bean with name
'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration'
I suspect this is some kind of configuration based error, but I am unable to pin point the source of the error.
I have seen some posts with this error and tried those resolutions. But those didn't help me resolve the error.
Here is my application's setup.

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Process finished with exit code 1
I am hoping that this application would run successfully and I would be able to see JSON output of all user entries with https://localhost:8080/getAllUsers.

Change
findAppUserDTOSByUserName(String userName), findAppUserDTOSByUserId(Integer userId);
To
findByUserName(String userName), findByUserId(Integer userId);
The query builder mechanism built into Spring Data repository
infrastructure is useful for building constraining queries over
entities of the repository. The mechanism strips the prefixes find…By,
read…By, query…By, count…By, and get…By from the method and starts
parsing the rest of it. The introducing clause can contain further
expressions such as a Distinct to set a distinct flag on the query to
be created.
Also, note that you don't need to use #ResponseBody with #RestController as it is active by default. Change Return Type of getAllUsers() from Object to List<AppUserDTO>

RequestMapping of SpringBoot Not working

I am learning Spring Boot for building Applications. I am trying to build my first Spring Boot Application with a controller in different package as application. Tomcat instance comes up but request does not reach RestController registered for the URI.
Following is the controller class:
package com.spring.controllers;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class HelloController {
#RequestMapping(value = "/abc")
public String getHi() {
System.out.println("End Point hit");
return "Hi";
}
}
Following is the application class:
package com.spring.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication(scanBasePackages = {"com.spring.controllers"})
public class SpringBootMain {
public static void main(String args[]) {
SpringApplication.run(SpringBootMain.class, args);
}
}

I have added base package scan and even tried with #ComponentScan annotation, but the result is same when I hit URL (http://localhost:8080/abc):
There was an unexpected error (type=Not Found, status=404).

Did anyone else face the same issue? Please suggest as how did you solve this.

Your Controller should be in the Child package of SpringBootApplication.
e.g if your SpringbootApplication main method is under com.text.demo package then your Controller class should be under com.text.demo.controller.
or add
#ComponentScan("com.text.demo.controller") on Spring boot Application main class.

As people mentioned in the comment try to add your base package.
#SpringBootApplication(scanBasePackages = {"com.spring"})
Or
#SpringBootApplication
#ComponentScan("com.spring")
But why don't you use this spring initializr https://start.spring.io/ to create a spring boot project from scratch. You can also add any dependency you need.
Here is the mini controller that I tried to reproduce from your example:
SpringApplication
package com.example.demo.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan("com.example.demo.controller")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}

and it works just fine!

As a suggestion, try calling default actuator endpoints e.g. http://localhost:8080/error. They come up with the Spring Boot and will show the actual status of your service.

Change your parent version number to below:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>

The issue might be due to wrong import of #Service annotation. It should be a stereotype one.
Use this in your service class as usage of component scan in Springboot is not a better practice.
import org.springframework.stereotype.Service;

All Spring-Boot Application always show a popup login

I'm using Spring and Spring Boot framework with Spring Security for a simple login projects with simple UI. In all my projects, using STS, after starting my application and run the localhost address without errors, i receive a popup login window and not my html page.
If i use user and default security password i always get a Whitelabel Error Page as results. Furthermore, if i use incorrect value the popup remain, if instead i use the default access value i get this message.
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Wed Aug 23 20:14:22 CEST 2017
There was an unexpected error (type=Not Found, status=404).
No message available
Here is a simple project code. All the html files are in template folder as you can see in project structure. I also try to use server.error.whitelabel.enabled=false in my application.properties file.`
Why has the html interface never been shown?

You need to restructure your packages to that they fall under the package of your SpringbootUiLoginApplication or use #ComponentScan to tell the Spring Boot where to find your bean classes.

Following up on Ali's answer:
#SpringBootApplication implies #Configuration , #EnableAutoConfiguration and #ComponentScan
So, consider changing:
#Configuration
#EnableAutoConfiguration
public class SecurityConfig extends WebSecurityConfigurerAdapter
to:
#Component
public class SecurityConfig extends WebSecurityConfigurerAdapter
And to scan for beans in your entire package change:
#SpringBootApplication
public class SpringbootUiLoginApplication
to:
#SpringBootApplication
#ComponentScan("com.cyberdemon")
public class SpringbootUiLoginApplication

I got this when I didn't realize another Spring Boot application was running on port 8080. End that and you won't get that security modal.

could not found bean for MongoRepository (Spring Boot)

I am using spring boot and MongoDB.
Spring version : 4.3.9
Spring boot version : 1.5.4
I am creating a repository which implements MongoRepository interface, like below
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface HotelRepository extends MongoRepository<Hotel,String> {
}
But, whenever I am adding a dependency to HotelRepository compiler giving the error Field hotelRepository in com.demo.HotelController required a bean of type 'com.demo.HotelRepository' that could not be found.
#RestController
#RequestMapping("/hotel")
public class HotelController {
#Autowired
private HotelRepository hotelRepository;
#GetMapping("/all")
public List<Hotel> getAllHotels(){
return this.hotelRepository.findAll();
}
}
I've examine all the aspects from my side to resolve the error but all in vain. What I've R&D.
For HotelRepository there will be a default implementation provided out of the box. as per spring docs
I've annotated the interface with #Repository, so no need to put #Component
Adding dependency from spring context using #Autowired annotation, So it should pick created bean from spring context.
All the required files are in the same package, so no need to put #ComponentScan
Here is my main spring boot application class :
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class MongoWithBootApplication {
public static void main(String[] args) {
SpringApplication.run(MongoWithBootApplication.class, args);
}
}

Could someone please help me out here what am I missing?

Faced similar problem, Adding the following to Application class helped me resolving the problem
#EnableMongoRepositories(basePackageClasses = DeviceDataRepository.class)
In your case it could be
#SpringBootApplication
#EnableMongoRepositories(basePackageClasses = HotelRepository.class)
public class MongoWithBootApplication{ ... }

I was facing the same problem
Used below code to scan mongorepository packages
#SpringBootApplication
#EnableMongoRepositories(basePackages = {"//packages you want to scan for activiting mongo repositories"})
public class SpringBootMongoDBApp{ ... }
It resolved my problem

we need to activate mongo repositories using EnableMongoRepositories
#SpringBootApplication
#EnableMongoRepositories //specify packages to scan
public class MongoWithBootApplication{ ... }

I have the same structure and I just had to add this configuration:
Application.java
#Configuration
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
...
}
application.properties
spring.data.mongodb.uri=mongodb://localhost:27017/hotelDB
And the repository package have to be in a deeper level of Application.java class. Thats all
com.hotelDB
Application.java
repository (Package)
controller (Package)
service (Package)
...

After so much of struggle, finally I've resolved the problem.
There is nothing wrong in the code or annotation. The problem was spring boot's version.
However, I am still not sure what is the wrong in the version above 1.5.1.RELEASE .If anybody knows the root cause can edit or answer the question.
Problem : If I add spring-boot-starter-parent above 1.5.1.RELEASE, it gives me the above no bean error for MongoRepository. It gives error from 1.5.2 to 1.5.4 version. (1.5.4 was the last version till that I've tried and faced the no bean error)
Solution : It runs fine if I add spring-boot-starter-parent 1.5.1.RELEASE or below (1.5.0 was lowest version till I've tried).

Just tried and did not found any problem at all with my existing spring boot mongodb project with 1.5.4.RELEASE for spring-boot-starter-parent.
Earlier it was configured with 1.4.0.RELEASE.
