Why does the H2 console in Spring Boot show a blank screen after logging in?
提问by pacoverflow
I'm using Spring Boot 1.4.1 with the H2 database. I have enabled the H2 console as described in the reference guideby adding the following lines to my application.properties file:
我在 H2 数据库中使用 Spring Boot 1.4.1。我按照参考指南中的描述启用了 H2 控制台，方法是将以下几行添加到我的 application.properties 文件中：
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":
当我转到 Windows 版 Chrome 53 中的 H2 控制台时，我可以看到登录页面并单击“测试连接”按钮会导致“测试成功”：
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.
但是当我点击“连接”按钮时，屏幕变成完全空白。当我查看源代码时，我看到“抱歉，尚不支持 Lynx”（请参阅完整的源代码）。同样的事情发生在 Firefox 中。
Why is that happening? I believe I am using the correct JDBC URL, as 4 different people posted on this questionthat you should use jdbc:h2:mem:testdb.
为什么会这样？我相信我使用的是正确的 JDBC URL，因为 4 个不同的人在这个问题上发布了你应该使用的jdbc:h2:mem:testdb.

According to a blog post, a line needs to be added to
the configuremethod of the SecurityConfigclass if you have the spring-boot-starter-securitydependency in your project, otherwise you will see an empty page after logging into the H2 console:
根据一篇博客文章，如果你的项目中有依赖，需要configure在SecurityConfig类的方法中添加一行spring-boot-starter-security，否则登录H2控制台后会看到一个空页面：
http.headers().frameOptions().disable();
I added that line and it solved the problem.
我添加了该行并解决了问题。
Alternatively, the following line can be used (as mentioned here):
可替代地，下面的行，可以使用（如所提到的在这里）：
http.headers().frameOptions().sameOrigin();

I can resolve the same problem using the following code in my SecurityConfig class
我可以在我的 SecurityConfig 类中使用以下代码解决同样的问题
@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.
我不知道这条线是做什么的，也许有经验的人可以解释一下。

Add this to your application.properties
将此添加到您的 application.properties
security.headers.frame=false
