BeanCreationException: Error creating bean with name 'batchConfigurer' - spring

Question

I already went through the many link like : Spring Batch with two different datasource issue, but I'm still getting the below error. I have configured the two datasource in the Spring Boot Batch application.
Below error -
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchConfigurer': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Unable to initialize Spring Batch

Answer 1

You are getting the error dataSource or dataSourceClassName or jdbcUrl is required. Here is the issue in your code i.e prefix is not correct, update your code to following:
CommonConfig.java
#Configuration
#EnableBatchProcessing
#PropertySource("classpath:scheduler.properties")
public class CommonConfig {
#Bean
#Primary
#ConfigurationProperties(prefix = "spring.primary.datasource")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
#Bean
#ConfigurationProperties(prefix = "spring.secondary.datasource")
public DataSource secondaryDataSource() {
return DataSourceBuilder.create().build();
}
}
Please refer to this link https://medium.com/#joeclever/using-multiple-datasources-with-spring-boot-and-spring-data-6430b00c02e7

Answer 2

I was able to solve this issue like below :
#Bean
#Primary
#ConfigurationProperties("spring.dsmysql")
public DataSourceProperties firstDataSourceProperties() {
return new DataSourceProperties();
}
#Bean
#Primary
#ConfigurationProperties("spring.dsmysql")
public DataSource primaryDataSource() {
return firstDataSourceProperties().initializeDataSourceBuilder().build();
}
#Bean
#ConfigurationProperties("spring.dspost")
public DataSourceProperties secondDataSourceProperties() {
return new DataSourceProperties();
}
#Bean
#ConfigurationProperties("spring.dspost")
public DataSource secondaryDataSource() {
return secondDataSourceProperties().initializeDataSourceBuilder().build();
}
and add
spring.dsmysql.type=com.zaxxer.hikari.HikariDataSource

Answer 3

Check your application.properties file like below.
Note: springbatch is my DB name
spring.datasource.url=jdbc:mysql://localhost:3306/springbatch
spring.datasource.username=root
spring.datasource.password=Vishal#123
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.batch.jdbc.initialize-schema=always
