Unable to use HikariCP in Spring Boot 1.5.18 with multiple data source configuration - spring-boot

Question

We are using multiple datasource configuration in our spring boot app.
both dataasources belongs to mysql only.
Configured multiple data source using:
https://medium.com/#joeclever/using-multiple-datasources-with-spring-boot-and-spring-data-6430b00c02e7
pom.xml changes:
<!-- exclude tomcat jdbc connection pool, use HikariCP -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
<exclusions>
<exclusion>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- exclude tomcat-jdbc, Spring Boot will use HikariCP automatically -->
<dependency>

.properties****:
spring.db1.datasource.jdbcUrl=jdbc:mysql://localhost:3306/db1?zeroDateTimeBehavior=convertToNull
spring.db1.datasource.driverClassName=com.mysql.jdbc.Driver
spring.db1.datasource.username=root
spring.db1.datasource.password=
spring.db2.datasource.jdbcUrl=jdbc:mysql://localhost:3306/db2?zeroDateTimeBehavior=convertToNull
spring.db2.datasource.driverClassName=com.mysql.jdbc.Driver
spring.db2.datasource.username=root
spring.db2.datasource.password=
Datasource Bean Config:
#Bean
#ConfigurationProperties(prefix = "spring.db1.datasource")
public DataSource db1DataSource() {
return DataSourceBuilder.create().build();
}
#Bean
#ConfigurationProperties(prefix = "spring.db2.datasource")
public DataSource db2Source() {
return DataSourceBuilder.create().build();
}
But when I ran it Got following exception:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.JpaVendorAdapter]: Factory method 'jpaVendorAdapter' threw exception; nested exception is java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName.
How to resolve this ?

Answer 1

You are missing driver dependencies in your pom
You need to add below lines to your pom.xml to include the database driver.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
