Failed to load class of driverClassName mongodb.jdbc.MongoDriver - spring-boot

Question

Can someone please help me out. I am suck here for 2 days now. I am working on spring boot with access to two(2) data-sources. The application using HikariCp to connect to Postgresql and Mongodb, but I am getting the mongodb error. If I point the mongodb to another database (like Mysql or so) it will work but not with mongodb.

Or if anyone can help with another approach that can be of help. Thank in advance

Answer 1

If I understand correctly, You are trying to use mongoDB with JDBC. I think this is not a common practice use JDBC with mongoDB. However if you want to use this way,there is unityJDBC , that you can use as JDBC driver. Also take a look at this.

Answer 2

If you want to connect monogoDb with JDBC, you can add these two lines in application.properties file for connecting mongodb with JDBC and to exclude autoconfiguration.
#connect mongodb with jdbc
spring.data.mongodb.uri=mongodb://localhost:27017/testDb\
#exclude jdbc autoconfiguration
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
Also put #EnableAutoConfiguration annotation in application's main.class
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class, XADataSourceAutoConfiguration.class})
Because the JPA auto configuration feature of the spring boot application attempts to establish database connection using JPA Datasource. The java class DataSourceAutoConfiguration is responsible for loading JPA DataSource. The auto configuration can be disabled by excluding DataSourceAutoConfiguration class from the spring boot context.
