Why does the H2 console in Spring Boot show a blank screen after logging in?

Question

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.propert

Answer 1

I can resolve the same problem using the following code in my SecurityConfig class

@Override
protected void configure(HttpSecurity http) throws Exception {
    bla();
    bla();   
    http.headers().frameOptions().sameOrigin();
}

I don't know what this line does, maybe someone with more experience can explain it.

Answer 2

Add this to your application.properties

 security.headers.frame=false

Answer 3

Along with the answer by @pacoverflow note the following:

As of Spring Boot 2.3.4. The DB Name is printed in the console: Connect using that DB name:

Answer 4

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();
