Spring – How to specify the .keystore file with Spring Boot and Tomcat

springspring-boottomcat

I'm trying to set up Spring Security to work with Spring Boot's embedded Tomcat instance. There are quite a few basic samples that do this but I'm stuck where they leave off — they do basic authentication over HTTP (not HTTPS).

I could probably make it work if I had access to the Tomcat configuration files (server.xml) but since Spring Boot uses an embedded Tomcat instance (which is otherwise a huge convenience), I dont have access to the Tomcat configuration files (at least, not to my knowledge).

There may be an application.properties setting for this but I haven't been able to track it down. I've seen references to a server.contextPath field in application.properties that I suspect may have something to do with replacement Tomcat config files. Even if it is related, I wouldn't know where to begin anyway — all of the Tomcat SSL instructions I've seen start with editing an existing server.xml file, not building one from scratch.

Can this be done with Spring Boot (either by somehow specifying a snippet of server.xml or through other means)? If not, what would be the simplest way to do this? I understand that I may need to exclude the Tomcat component of Spring Boot but I'd prefer to avoid that if possible.

Starting with Spring Boot 1.2, you can configure SSL using application.properties or application.yml. Here's an example for application.properties:

server.port = 8443
server.ssl.key-store = classpath:keystore.jks
server.ssl.key-store-password = secret
server.ssl.key-password = another-secret

Same thing with application.yml:

server:
  port: 8443
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: secret
    key-password: another-secret

Here's a link to the current reference documentation.

C# – How to change the Page Title in ASP.Net 1.1

With ASP.Net 1.1, first you have to set the runat attribute on the title markup :

<title id="PageTitle" runat="server">WebForm1</title>

Then from the code behind :

// We need this name space to use HtmlGenericControl
using System.Web.UI.HtmlControls;

namespace TestWebApp
{

      public class WebForm1 : System.Web.UI.Page
      {
            // Variable declaration and instantiation
            protected HtmlGenericControl PageTitle = new HtmlGenericControl();

            private void Page_Load(object sender, System.EventArgs e)
            {
                  // Set new page title
                  PageTitle.InnerText = "New Page Title";
            }
      }
}

Imports System.Web.UI.HtmlControls

Namespace TestWebApp

    Public Class WebForm1
        Inherits System.Web.UI.Page

        Protected PageTitle As HtmlGenericControl = New HtmlGenericControl()

        Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

            PageTitle.InnerText = "New Page Title"
        End Sub

...

    End Class
End Namespace

Java – How to configure HikariCP in the Spring Boot app in the application.properties files

@Configuration
@ConfigurationProperties(prefix = "params.datasource")
public class JpaConfig extends HikariConfig {

    @Bean
    public DataSource dataSource() throws SQLException {
        return new HikariDataSource(this);
    }

}

application.yml

params:
  datasource:
    driverClassName: com.mysql.jdbc.Driver
    jdbcUrl: jdbc:mysql://localhost:3306/myDb
    username: login
    password: password
    maximumPoolSize: 5

UPDATED! Since version Spring Boot 1.3.0 :

Just add HikariCP to dependencies
Configure application.yml

application.yml

spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:h2:mem:TEST
    driver-class-name: org.h2.Driver
    username: username
    password: password
    hikari:
      idle-timeout: 10000

UPDATED! Since version Spring Boot 2.0.0 :

The default connection pool has changed from Tomcat to Hikari :)
