I already have a couple of days in this and although I know they may see the title of the question repeated, the truth is that I have already tried several solutions that have worked for others but not me. The most likely thing is that it's really very silly and I have not seen it yet but I'm on the edge.
This is my pom.xml

This is my class Application
package ar.com.paises;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
#RestController
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
#RequestMapping("/")
String home() {
return "Hello World!";
}
}
And this is my .properties
spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.datasource.url=jdbc:mysql://localhost:3306/test_avantrip?verifyServerCertificate=false&useSSL=false&requireSSL=false
server.port=8083
spring.profiles.active=#spring.profiles.active#
The only message I receive is the following
404 not found api
This is the guide that I was following
Any suggestions?
Update
#RequestMapping(value="/hi", produces= {MediaType.TEXT_PLAIN_VALUE })
public String home() {
return "Hello World!";
}
nothing yet
Update 2
I changed the port, removing it from the .properties and leaving it in 8080 I do not see any change. Additionally here are the messages of the spring boot console when I start it

try removing the property spring.profiles.active=#spring.profiles.active#
Move the #RequestMapping("/") to a controller class, something like :
#RestController
public class Controls {
#RequestMapping("/")
public String home() {
return "Hello World!";
}
}
So your main method would look like :
#SpringBootApplication
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
}
If you take a look at the console logs you won't see that the path "/hi" is not being mapped, which means spring is not able to find your controller bean.
when a path is mapped you should see something like the following in
RequestMappingHandlerMapping : Mapped "{[/hi],methods=[GET]}".
Please move the rest Controller to its own class, it can be in the same File but move it to a new different class something like the following:
package ar.com.paises;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
public class PaisesApplication {
public static void main(String[] args) {
SpringApplication.run(PaisesApplication.class, args);
}
}
#RestController
class HiController {
#RequestMapping("/hi")
String home() {
return "Hello World!";
}
}
Also, make sure that when you're deploying your application a log as the previous one appear.
The way you should call your endpoint according to your port should be:
http://localhost:8083/hi

I added an annotation #Repository into Repository, added an annotation #Transactional into Controller in add method, into the signature of the same method added an anotation #ResponseBody but that didn't solve the issue.
I'm new to java and Spring and I'm currently trying to understand aop. I'm trying to implement very simple code with my custom annotation and #After advice and for some reason it does not work, what I expected was to get on the console 1 and the 2 insted I get only 1 do any of you guys know why?

Here you create the instance by your self. Spring can not use any aspect on that as it does not belong to the spring context.
Simulation_service mm = new Simulation_service();
mm.metoda();
You need to retrieve the instance from the spring context. Then invoking the method will cause the aspect to execute.
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(DemoApplication.class, args);
Simulation_service mm = context.getBean(Simulation_service.class)
mm.metoda();
}
If everything else is fine tuned it will work. In every case what I describe here is a must in order to move forward.
Turns out advice and custom annotation can't be in the same class which is understandable given the reason for which aop was created, I moved method with custom annotation metoda() to another class and marked it ith #Bean annotation
I am creating a simple Spring Boot application with JpaRepository, but when I am trying to run my application it gives an error that "NoSuchBeanDefinitionException". I am new to Spring Boot.
I have also tried to annotate my main class with #SpringBootApplication
#EnableJpaRepositories("com.ab.repository") annotations but whenever I am trying to annotate #EnableJpaRepository(), it is showing error in STS that
The type org.springframework.data.repository.config.BootstrapMode cannot be resolved. It is indirectly referenced from required .class files.
Previously I was not using this annotation but I saw in a question that I have to tell my class to enable JPA repository, so I tried this as well, but it is also not working.
My main class
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class SpringBootMain {
public static void main(String[] args) {
SpringApplication.run(SpringBootMain.class, args);
}
}

Please correct me what I am doing wrong, I am Expecting it to run properly but I am getting an error message:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.ab.repository.WebServiceRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
After looking through your code that you posted on github i pulled it and rightfully so you have problems with your dependencies. You where missing the spring build plugin that includes all the dependencies in the jar.
Always use the Spring initlizr when starting a new project and it will set up all this for you automatically (unless you have good experience with spring and know what you are doing).

you also need to update your application properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
or else you will get a warning when you start your server.
Remove “#Repository”, maybe you can
I created both the folder structure and code like yours.
package com.ab;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class SpringBootTry1Application {
public static void main(String[] args) {
SpringApplication.run(SpringBootTry1Application.class, args);
}
}
Why you change your main class name?Spring boot automatically create main class for you.

My code compiles fine.
Try to create new spring starter project from STS and do not touch spring boot main class and copy the same folder structure from here.Your code will definitely compiles.
I have created a webapp using Spring Boot and REST APIs in Eclipse. When I try to run it using Tomcat 8, it gives the error
"o.a.tomcat.jdbc.pool.ConnectionPool: Unable to create initial connections of pool."
I tried using the solutions provided but nothing seemed to work, it always gives the same error.
This is my application.properties file -
spring.datasource.url = jdbc:mysql://localhost:3306/dbase?autoReconnect=true&useSSL=false

You have to change quite few things
1.Goto your mysql installed directory in C drive and find my.ini file.
Change default_authentication_plugin to this
default_authentication_plugin=mysql_native_password
and then goto your MySQL command line client,
After logging in, run this query:
ALTER USER 'yourusername'#'localhost' IDENTIFIED WITH mysql_native_password BY 'yourpassword';
then restart the mysql service and run your program.
replace "yourusername" and "yourpassword" with your actual username and password of MySQL.
Goto POM and replace:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
with latest MySQL8 connector
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.15</version>
</dependency>
i hope it helps :)
These are the things to check
Verify if the database server up and running, and your connection details are working fine in a standalone test.
Grant access if not present, visit :
Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server
Why are you running spring boot within tomcat in the first place and not as a fat jar ?
Secondly, the mysql client JAR should be included in tomcat library
Increase mySQL max connection count, if server is running out of available connections
I'm trying to create a basic controller on spring boot but I get:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing
this as a fallback.
Fri Dec 14 21:21:36 ART 2018 There was an unexpected error (type=Not
Found, status=404).
No message available
error. I have the controller in a subpackage of the package where the application is located as it should be.

Folder strucure
It can be from #Controller annotion. Please change it to #RestController
From spring boot documentation https://spring.io/guides/gs/rest-service/
In Spring’s approach to building RESTful web services, HTTP requests are handled by a controller. These components are easily identified by the #RestController annotation, and the GreetingController below handles GET requests for /greeting by returning a new instance of the Greeting class:
#Controller annotation represents the Spring MVC Controller. If you mark your class with #Controller annotation you have to put #ResponseBody on the handler methods.
On the other side, #RestController annotation is a specialized version of #Controller which adds #Controller and #ResponseBody annotation automatically so there is no need to add #ResponseBody to our handler methods.
#RestController
public class HomeController {
#RequestMapping("/")
public String home(){
return "home";
}
}
or
#Controller
public class HomeController {
#RequestMapping("/")
#ResponseBody
public String home(){
return "home";
}
}
For information : If you do not specify any mapping this method will resolve all the http request i.e. you can send GET, POST, HEAD, OPTIONS, PUT, PATCH, DELETE, TRACE request to the specified url and it will be resolved.
For you case, you change just your controller to look like :
package com.example.demo.home;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#RestController
public class HomeController {
#RequestMapping("/") // Or you can do : #GetMapping("/")
public String home(){
return "home";
}
}
The url:
http://localhost:8080/
For your code/configuration, it will look for the html file under static or webapp folder, meanwhile your home controller should return home.html not home.
Thymeleaf should be included in project's pom.xml as a dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Also the home.html file should be moved from templates to static directory.
