Can't Start the Spring Boot Application

I am trying to connect the database in my spring boot project. I have already created a database using phpMyAdmin. The MySQL server is running on port 3307.
But I couldn't run the application.

Use Spring Boot get entity from Oracle DataBase not work

I want to use Spring boot get entity from Oracle DB(Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production)
when i use repository findById method and toString in Console, it only return like this
LogReturnEmail [createDtm=, fileName=, forwardResult=, forwardTo=, id=f6a70923-973a-47ac-98a0-34200d4ddacb, mailSubject=, messageNo=, messageType=, sellerCompid=]
only id column have value.but i want to get all value.
Main class
#SpringBootApplication
public class Demo2Application implements ApplicationRunner {
#Autowired

public void run(ApplicationArguments args) throws Exception {
Optional<LogReturnEmail> xml = repo2.findById("f6a70923-973a-47ac-98a0-34200d4ddacb");
System.out.println(xml.get());
}
}
Repository
#Repository

}
LOG_RETURN_EMAIL entity

Spring boot REST API 404 error

I am trying to create a basic spring boot application (JDK 1.8) with a REST API .
The following is my application code
package org.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan("org.demo")
#EnableAutoConfiguration
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
I have added a simple controller as follows
package org.demo.controllers;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
#RestController(value = "/hello")
public class HelloController {
#GetMapping
#ResponseBody
public String hello() {
return "Hello";
}
}

I am not sure what I might be missing. Please help.

I got the solution. It was due to package visibility. Main class was not able to found package in which controller class is present. So added all classes under same package. You can also place application class one level up. Got help from below link:
Spring Boot: Cannot access REST Controller on localhost (404)

Test as follow... did the trick for me remove the path from the notation #RestController then add the path #GetMapping notation as follow #GetMapping("/hello") test http://localhost:8080/hello you should get a correct response in order to have a response for this request http://localhost:8080/hello/hello need to add the follow:
#RestController
#RequestMapping(value = "/hello")

change to :
#RestController
#RequestMapping(value = "hello-controller")
public class HelloController {
#GetMapping(value="hello")
#ResponseBody
public String hello() {
return "Hello";
}
}
so you can use your api from : localhost:8080/hello-controller/hello
value in #RequestMapping below #RestController is define your class address.
value in #GetMapping is for your API address.
Hope this explanation help you.

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).
No message available
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);
}
}
Controller
package com.example.demo.controller;
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";
}
}

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;

Embeded Mongodb to Spring Boot always recreate database

I need to embed Mongodb to Spring Boot application. But the way how I've done
it leads to re-creating mongo db every time I start app. I mean, my documents don't save to database persistently.
Every start I see in logs:

Probably this part leads to database overwriting:

Controller for storing document:
#RequestMapping("/check")
#ResponseBody
public List<Domain> check(){
System.out.println("/check");
Domain domain = new Domain(i++, "Check_"+String.valueOf(i), true);
dm.save(domain);
return dm.findAll();
}
Repository:
public interface DomainRepository extends MongoRepository<Domain, Long> {
Domain findFirstByDomain(String domain);
Domain findByDomainAndDisplayAds(String domain, boolean displayAds);
//Supports native JSON query string
#Query("{domain:'?0'}")
Domain findCustomByDomain(String domain);
#Query("{domain: { $regex: ?0 } })")
List<Domain> findCustomByRegExDomain(String domain);
}
appilcation.properties:
server.port = 8091
spring.data.mongodb.repositories.enabled=true
spring.data.mongodb.database=testme
How can I solve this isssue?

Because it's embedded, every time application is started the DB will be re-created as previous one has been deleted when the app was stopped.
