'spring-boot-starter-data-jpa dependency error

I am using new version of Spring boot - 1.5.7. But , when I create new spring starter project with jpa dependency, I got strange error:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.sql.DataSource' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Could anybody help me: Here is my pom.xml

Solution 1:[1]

You need to include a database in your dependencies. If a database was found, spring boot auto-configures your datasource for you.

See this example, which includes a h2database.

https://spring.io/guides/gs/accessing-data-jpa/

Solution 2:[2]

You need to put your database related info in the application.properties file

spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword

And you need to put the database dependency in your pom.xml

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

this is how it's listed in the official site for mysql, you can try with your database of choice.

Solution 3:[3]

You need to place the database in dependencies in the file pom.xml according to the database used in the application.yml file:

  1. application.yml file:

datasource:
  url: jdbc:postgresql://localhost:5432/your-database
  username: user
  password: password
  1. pom.xml file:

<dependency>
  <groupId>org.postgresql</groupId>
  <artifactId>postgresql</artifactId>
  <scope>runtime</scope>
</dependency>
