Why does the H2 console in Spring Boot show a blank screen after logging in?
h2, java, spring-boot
Solution
According to a blog post, a line needs to be added to the `configure` method of the `SecurityConfig` class if you have the `spring-boot-starter-security` dependency in your project, otherwise you will see an empty page after logging into the H2 console:
http.headers().frameOptions().disable();
I added that line and it solved the problem.
Alternatively, the following line can be used (as mentioned here):
http.headers().frameOptions().sameOrigin();
Problem
I'm using Spring Boot 1.4.1 with the H2 database. I have enabled the H2 console as described in the reference guide by adding the following lines to my application.properties file: ``` spring.h2.console.enabled=true spring.h2.console.path=/h2 ``` When I go to the H2 console in Chrome 53 for Windows, I can see the login page and clicking the "Test Connection" button results in "Test successful": But when I click on the "Connect" button, the screen turns completely blank. When I view the source, I see "Sorry, Lynx not supported yet" (see the full source). The same thing happens in Firefox. Why is that happening? I believe I am using the correct JDBC URL, as 4 different people posted on this question that you should use `jdbc:h2:mem:testdb`.
