Spring security core plugin pdf

It is one of the most powerful and highly customizable authentication and access control frameworks in the Java ecosystem. This article is going to focus on Spring Security Form Login which is one of the most necessary parts of web applications. The example I am presenting here is a part of pdf Programming Discussion Forum , a web application built with Spring 5, Hibernate 5, Tiles, and i18n.

The main Maven dependencies required for form login are spring-security-web and spring-security-config. However, to provide database backed UserDetailsService , we need to have dependencies to support that as well. You can checkout pom. Let us create two Entity classes, named as User and Authority , to map with database tables as follows. It is always good to have authorities as configurable value, but for ease, let us define this as an enum for now.

Once entities are defined, you can put import. In order to retrieve a user associated with a username, let us create UserRepositoryImpl which implements UserRepository as below:.

We need to implement the org. UserDetailsService interface in order to provide our own service implementation. I have added UserDetailsServiceImpl which implements UserDetailsService to retrieve the User object using the repository , and, if it exists, wrap it into a PdfUserDetails object, which implements UserDetails , and returns it as below:.

PdfUserDetails model is defined as below:. Let us add LoginController to handle custom success and failure during login. This has other methods that we can use to configure the behavior of the form login:. Now, we need to let Spring know about our Spring Security Config by registering on root config as below:. I have skipped including HibernateConfig. But you can find them on the GitHub repository.

Note here, the action doLogin for form submission is same as of the login processing URL in the security config above. If login authentication is successful, then it redirects to the homepage.

If you click on logout button once you are logged in, then it will take you to the home page after clearing all the session. But that didn't change anything. What could be done to resolve this problem and download the plugin correctly? Add a comment. Active Oldest Votes. Igor Artamonov Igor Artamonov That helped. Thank you!

As you can see, there is some version of Grails 4 but we will install and use the stable version of Grails 4 by type this command. Go to the newly created Grail 4 application. For sanitation, start this Grails 4 application by type this command inside Grails interactive console.

To add the Grails Spring Security Plugin, open and edit "build. Then add this line to the dependencies. Still, on Grails interactive console, type this command to generate the User and Role domain class.
