I am working on SpringBoot api and using H2 database with following property settings.
spring.h2.console.enabled=true
spring.datasource.name=test
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.datasource.initialization-mode = embedded
spring.datasource.url=jdbc:h2:mem:test
spring.jpa.hibernate.ddl-auto = update
When I want to use browser to view the H2 database console through 'http://localhost:8082/h2-console', a screen open in browser with connect and test connection button. When I click on Test Connection, it returns successful but when click on Connect button, error comes that localhost refused to connect.
add this two lines in your spring security file and you are good to go.
http.csrf().disable();
http.headers().frameOptions().disable();
