Form-based authentication with GWT and Spring Security

We will demonstrate Form-based authentication in GWT. It's very similar to the authentication that we have done in our previous recipes. We will be editing the applicationContext.xml.

Getting ready

• Create a sample GWT project.
• Add the spring-related JARs in the build path.
• Add the Spring Security-related JARs.
• Add the applicationContext.xml file.
• Edit the web.xml file as shown in the previous section.
• Also add the spring-related JARs in the web-inf lib folder.

How to do it...

Edit the applicationContext.xml file:

<http auto-config="true" >
  <intercept-url pattern="/basicgwtauth/**"
     access="ROLE_AUTHOR"/>
        <intercept-url pattern="/basicgwtauth/**" access="ROLE_AUTHOR"/>
        <intercept-url pattern="/**/*.html" access="ROLE_AUTHOR"/>
        <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" ...
