I am trying to run my Spring Boot backend with two profiles, one using H2 in memory database and the second one using MySQL. H2 database works just fine, but when I switch to MySQL I get
APPLICATION FAILED TO START
***************************
Description:
Failed to bind properties under '' to com.zaxxer.hikari.HikariDataSource:
Property: driverclassname
Value: com.mysql.jdbc.Driver;
Origin: "driverClassName" from property source "source"
Reason: Failed to load driver class com.mysql.jdbc.Driver; in either of HikariConfig class loader or Thread context classloader
Action:
Update your application's configuration
I have tried deleting .m2, reimporting, maven clean, compile, install and most of the things I could find on the internet, no success. The funny thing is that I have other project with MySQL database only, I had similar issue, but adding mysql-connector-java dependency solved it. I have no clue right now.

In my case the next dependency was missing:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
In case of using IntelliJ and if you inherit from a <parent>, you can view your effective pom.xml by right clicking anywhere inside your pom.xml, then:
and search for the mysql-connector-java artifact as mentioned.
The answer is so embarrassing. I appended the driver line of application.properties with a semicolon ... Obviously, it did't recognize that driver.
I had a problem where I was using Spring Boot 2.2.0.RELEASE and needed to connect to an old Mysql DB (5.1.73), which required me to downgrade to mysql-connector-java version 5.1.38
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency>
Since Spring boot was expecting a newer mysql-java-connector, which has been renamed to com.mysql.cj.jdbc.Driver, I also had to add the spring datasource driver-class-name setting in my spring boot db config.
So my spring boot config ended up like this:
spring:
datasource:
url: 'localhost'
password: password
username: user
driver-class-name: com.mysql.jdbc.Driver
just add mysql and jdbc dependencies like below
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jdbc</artifactId>
</dependency>
You don't specify version of MYSQL JDBC driver, so you're likely getting version 8.x, where the driver is named differently than in previous versions:
com.mysql.cj.jdbc.Driver
In my case error throws:
Property: driverclassname
Value: com.mysql.cj.jdbc.Driver
Origin: "driverClassName" from property source "source"
Reason: Failed to load driver class com.mysql.cj.jdbc.Driver in either of HikariConfig class loader or Thread context classloader
So I have just added mysql dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
Try upgrading your driver. Coz Mysql community has updated class name from com.mysql.jdbc.Driver to com.mysql.cj.jdbc. Check More Details
Change the database driver dependency scope to 'runtime'
For example:
<dependency>
<groupId>com.{yourDatabaseGroupid}</groupId>
<artifactId>{yourDatabaseArtifactId}</artifactId>
<scope>runtime</scope>
</dependency>
You should add: spring.datasource.driver-class-name=com.mysql.jdbc.Driver to your application.properties file .
My **application.properties : **
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.datasource.url=jdbc:mysql://localhost:3306/db_name?useSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC&zeroDateTimeBehavior=convertToNull
spring.datasource.username=root
this issue for me was also caused by the version of mysql. all i had to do is add the version of mysql in pom.xml dependencies (in my case the verion is 8.0.25)
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.25</version>
</dependency>
make sure to reload the maven dependecies before your run
I cant believe it! In intellij: Build->rebuild project solved the issue for me!
For more information:
pom.xml:
application.properties:
Spring boot 3.xx has updated its dependency
try this
runtimeOnly("com.mysql:mysql-connector-j")
<dependencies>
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-connector-j</artifactId>
<scope>runtime</scope>
</dependency>
</dependencies>
I had the same problem as you. For me, it was because of having h2 database dependency! I don't know how these two can affect each other, but all I did was removing this dependency and now it works just fine!
I my case all configurations were correct but I still get this error.
In Intellij, go in the project structure (ctrl + alt + maj + S) in windows. Look if u get some problems.
If yes, go on maven in the sidebar: clic on "Generate sources and Update Folders for All projetct"
That resolve my error !
Had to specify the jar path inside project->Properties->JPA-> connection Profile -> JAR List
I had the same issue and the root cause was [ spring.profile.active ] and the fix is [ spring.profiles.active ] where it is profiles plural and it was my mistake.
go to In that site: Dependencies > Search for Mysql drver > select it > Click explore button > copy the latest version of mysql connector > add it into your application.properties file
/I solved it just by placing these two lines./
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
implementation 'org.springframework.boot:spring-boot-starter-data-jdbc'
Can't comment, here's another updated alternative (to @Janac Meena's comment) for Gradle
implementation 'com.mysql:mysql-connector-j:8.1.0'
Check for more versions here. My mistake was spelling the above as mysql-connector-java:8.1.0 instead of mysql-connector-j:8.1.0.
