Spring Security with Vaadin – Spring form-based authentication

We will demonstrate form-based authentication in Vaadin. It's very similar to the authentication that we used in our previous recipes. We will be editing the applicationContext.xml file. We are not creating any customized login form, we would like to use spring internal login form.

Getting ready

You have to comment the <http-basic/> tag from the application-Context.xml file.

How to do it...

Edit the applicationContext.xml file as shown in the following code:

<http auto-config="true">
  <intercept-url pattern="/Vaadin_Project1/**"
     access="ROLE_EDITOR"/> 
  <intercept-url pattern="/Vaadin_Project1/*.*"
     access="ROLE_EDITOR"/> 
  <intercept-url pattern="/**" access="ROLE_EDITOR" />
</http>
<authentication-manager>
  <authentication-provider>
    <user-service>
       <user name="anjana" password="123456"
       authorities="ROLE_EDITOR" />
    </user-service>...
