Spring Kicking Mistake - Mistake Creating A Edible Bean Alongside Get Upwardly 'Datasource' Defined Inwards Degree Path Resources Datasourceautoconfiguration

Hello guys, If you lot are using Spring Boot too getting errors similar "Cannot create upwards one's heed embedded database driver cast for database type NONE" or "Error creating a edible bean alongside hollo 'dataSource' defined inwards cast path resources ataSourceAutoConfiguration" too thus you lot convey come upwards to the right place. In this article, we'll examine dissimilar scenarios on which this Spring Boot fault comes too what you lot tin create to solve them. The full general argue for this fault is Spring Boot's auto-configuration, which is trying to automatically configure a DataSource for you lot but doesn't convey plenty information. It is automatically trying to create an instance of DataSourceAutoConfiguration edible bean too it's failing.

Like other Spring frameworks errors, the stack delineate looks quite messy, something which they could convey improved alongside Spring Boot, but the gest is hither are these 2 errors I mentioned above.

Let's run into the stacktrace looks inwards general:

org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.sql.DataSource org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$NonEmbeddedConfiguration.dataSource()] threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Cannot create upwards one's heed embedded database driver cast for database type NONE. If you lot desire an embedded database delight seat a supported 1 on the classpath.:
[INFO] org.springframework.beans.factory.BeanCreationException: Cannot create upwards one's heed embedded database driver cast for database type NONE. If you lot desire an embedded database delight seat a supported 1 on the classpath.


Btw, these errors tin live on intimidating if you lot are completely novel to Spring framework. In that case, I propose you lot locomote through a comprehensive Spring Boot class similar the Learn Spring Boot past times Dan Vega on Udemy.   Now, let's run into some mutual create of this fault too what you lot tin create to solve this problem.

1) Spring Boot Error due to Starter Dependency

Some of my friends too readers got this fault fifty-fifty if they don't bespeak a Database. The top dog argue they were getting this fault was because of starter dependency similar some of they convey included spring-boot-starter-data-jpa which too thus included hibernate-entitymanager.jar too they didn't convey additional things bespeak to laid that up.

Sometimes including incorrect Starter POM tin also solve this work similar adding spring-boot-starter-jdbc instead of spring-boot-starter-data-jpa dependency.

If you lot know, Spring Boot auto-configuration is triggered past times JAR dependencies introduce inwards the classpath too if it pulls something which you lot don't bespeak too thus this type of fault tin come.

That's why a expert noesis of Spring fundamentals are needed to purpose Spring boot correctly. If you lot are novel into the Spring framework, I propose you lot locomote through Learn Spring: The Certification Class by Eugen Paraschiv of Baeldung to acquire Spring five too Spring Boot 2 from scratch, inwards a guided, code-focused way

2) Due to Missing Dependency

Sometimes you lot create bespeak a database but you lot forgot to include the driver JAR file into the classpath, which tin also create this error. For example, you lot convey specified the next properties inwards the application.properties, boundary boots configuration file but didn't include the corresponding MySQL JDBC driver into the classpath

spring.datasource.url = jdbc:mysql://localhost/test
spring.datasource.driver-class-name= com.mysql.jdbc.Driver

In social club to solve this error, either you lot bespeak to include the right Starter POM dependency or manually add together the MySQL JDBC JAR file into the classpath. If you lot are interested, you lot tin run into this tutorial to acquire to a greater extent than almost how to connect a Java application to a database using a MySQL database inwards this tutorial.

3) Due to Missing Configuration inwards Application.properties

Spring Boot is expert at configuring in-memory Databases similar H2, HSQLDB, Derby, etc too it tin configure them past times only adding their JAR files into the classpath but for others, you lot bespeak to give Spring Boot additional details similar URL, DriverClass name, etc.

You tin create that past times adding some properties to application.properties file alongside the spring.datasource prefix, equally shown inwards next example:

spring.datasource.url = jdbc:mysql://localhost/abc
spring.datasource.name=testme
spring.datasource.username=xxxx
spring.datasource.password=xxxx
spring.datasource.driver-class-name= com.mysql.jdbc.Driver spring.jpa.database=mysql
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect

This volition render the Spring Boot auto-configuration ingredient to configure the database for you. If you lot desire to acquire to a greater extent than almost how auto-configuration plant inwards Spring Boot, I propose you lot locomote through a comprehensive Spring boot class like @EnableAutoConfiguration annotation of Spring Boot equally shown below:

@Configuration @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) public class SpringBootDemo {     public static void main(String[] args) {    SpringApplication.runSpringBootDemo.class, args);   }   }

You tin fifty-fifty exclude to a greater extent than than 1 classes using exclude attribute alongside @EnableAutoConfiguration equally shown below:

@Configuration @EnableAutoConfiguration( exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class}) public class SpringBootDemo {     public static void main(String[] args) {      SpringApplication.runSpringBootDemo.class, args);   }   }

That's all about how to solve "Cannot create upwards one's heed embedded database driver cast for database type NONE" or "Error creating a edible bean alongside hollo 'dataSource' defined inwards cast path resources DataSourceAutoConfiguration" problem. In most of the cases, it is because of auto-configuration doesn't convey plenty details require to configure Database but sometimes it's also the accidental trigger of database auto-configuration which tin live on disabled using exclude attribute of @EnableAutoConfiguration annotation.
