Spring Vault Integration with Spring Boot App

I am trying to integrate Spring Vault with my application but as soon as I run the application it is throwing exception. I am following Spring IO Documents since I am new to the vault integration but couldn't figure out the exception because I am providing all the information required in the bootstrap
file.

This is my Bootstrap.yml file
spring:
cloud:
vault:
profiles: dev
scheme: http

This is my Config file
#Configuration
public class config{

public DataSource getDataSource() {
DataSource dataSource = DataSourceBuilder.create()
.password(environment.getProperty("spring.datasource.password"))
.username(environment.getProperty("spring.datasource.username"))
.driverClassName(environment.getProperty("spring.datasource.driver-class-name"))
.url(environment.getProperty("spring.datasource.url")).build();
return dataSource;
}
This is my main application
#SpringBootApplication

public class MainApplication {
public static void main(String[] args) {
SpringApplication.run(MainApplication.class, args);
VaultTemplate vaultTemplate = new VaultTemplate(new VaultEndpoint(),

VaultConfig.class);
System.out.println(response.getData().getUsername());
System.out.println(response.getData().getPassword());
}
}
This is the log which I am getting

You have almost everything correct except two problems in the Bootstrap.yml.
i. Indentation - vault is a sub property of cloud, so you'll have to push it with an additional space. Yaml takes indentation very seriously.
ii. Missing required attribute - token is a required attribute with your config so you'll have to add one.
These problems were noted in the error message you posted.
... Token (spring.cloud.vault.token) must not be empty.
Following Bootstrap.yml loads the context you noted in the MainApplication just fine:
spring:
cloud:
vault:
profiles: dev
scheme: http
port: 1111
host: 1.1.1.1
authentication: token
token: s3cr3t

Maven builds Spring Boot on local machine but not EC2 instance: UnsatisfiedDependencyException

I've been struggling for the past few hours getting Maven to build a JAR file of my Spring Boot project in an Amazon EC2 instance. If I build with IntelliJ or with mvn package in my local computer, everything's fine, no problems. However, if I pull the exact same code from the same repository into the EC2 instance and build it there (both times I use Java 8, have also tried Java 11), it shows this error stacktrace:
[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 5.373 s <<< FAILURE! - in com.courier.courier.CourierApplicationTests

I'd really appreciate any help on this issue.
Here's the pom.xml file if that's any helpful:

EDIT: Apparently the CourierApplicationTests class was directly at fault: removing it solved my issue. It doesn't really explain why it would build locally and not in EC2, so I'm going to keep this question open and supply the test file:
package com.courier.courier;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

SQL Server dependency is deprecated, use following to interact with SQL Server
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre8</version>
</dependency>
follow links for more information
Configuring Spring Boot for Microsoft SQL Server
Open sourcing the Microsoft JDBC Driver and Maven support

Since it is a REST app, need to add the spring-boot-starter-web dependency in pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.0</version>
</dependency>
Add also connection properties in config (application.properties by default):
spring.datasource.url=jdbc:sqlserver://localhost;databaseName=springbootdb
spring.datasource.username=sa
spring.datasource.password=replace_value
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.jpa.hibernate.ddl-auto = create-drop
Try that one and see if you can build/run the project.

Change your url parameter to:
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=test1
Port number must be preceded by a colon(":"), not slash("/").

Unable to establish connection with SQL Server 2014 - error creating bean

I have a micro-service which connects to the DB and returns an object of type string. When I try to run the application I see a bean creation error || error creating bean with name dataSource. I tried few options mentioned in stackoverflow but couldn't solve the issue, which made me to post this question. Here is the error, application properties & POM. Any suggestions are appreciated.
Note:
JAVA 6, Spring boot are used.
Thanks.

Looks as if your SQL Server driver is only loaded in your test scope:
<scope>test</scope>
If you're attempting to run the application itself, you'll need to include that on the runtime classpath. Just remove that scope declaration and it should work.

You don't have the SQL Server JDBC driver included in your application. The reason is that you have specified in the POM that the scope of this dependency is test. To fix this, remove <scope>test</scope> for the SQL Server JDBC driver and recompile and redeploy.
As an aside, the latest version of the SQL Server JDBC driver is
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.2.2.jre8</version>
</dependency>

How to configure sessionFactory and EntityManager in SpringBoot Application

I have configured datasource in application.yml and added spring-boot-starter-data-jpa in my pom.xml. I am getting the following error while starting the server.
"Caused by: java.lang.IllegalStateException: EntityManagerFactory must not be null"

You should add mysql dependency in pom.xml, because you are given data source driver as mysql
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
Here example Spring boot with mysql. And spring boot one of feature is AutoConfiguration.

Check if you have #SpringBootApplication or #EnableAutoConfiguration (added by #SpringBootApplication).
This will enable auto-configuration which will instantiate automatically the necessary beans for you based on the contents of your classpath.
Therefore check also the classpath to see that you added all the necessary dependencies.
SpringBoot helps you in adding these dependencies by providing starters which contain multiple dependencies.
In your case this one - spring-boot-starter-data-jpa - which you already added
Available starters
If this still doesn't work then is something missing from the configuration (application.yml)
You can try setting one of the following keys:
spring.jpa.database= # Target database to operate on, auto-detected by default. Can be alternatively set using the "databasePlatform" property.
spring.jpa.database-platform= # Name of the target database to operate on, auto-detected by default. Can be alternatively set using the "Database" enum.
There is a reference with common settings here.
NOTE: at any time you can define your own beans which will override the ones added by auto-configuration.
