The IS_AUTHENTICATED_* rules are built into Spring Security, but ROLE_USER is a role that must exist in the . Then against each incorrect authentication attempt, we can update and check with the database table. Create HomeController.java class inside in.bushansirgur.springsecurityexample.controller package and add the following content. Spring Security Roles Example Application Test Right Click on Project in Spring STS IDE and select "Run AS >> Run on Server" option. Below is a code snippet that you can use to add Spring Security to your Spring Boot Project. The Spring Method Level security is used in Spring Boot applications that have user Roles and Authorities configured. Our example is nice because we are able to leverage a lot of defaults. The main advantage to these annotations resides in their flexibility, as they can be as granular as needed. What if we wanted to run the test with a different username? Every spring boot application has the @SpringBootApplication annotation on its main class. It will access default Application welcome page as shown below: 3. To enable annotation based security, we need to configure <global-method-security> namespace. Annotate method using JSR-250 @RolesAllowed.

Spring Security 3.0 introduced the ability to use Spring EL expressions as an authorization mechanism in addition to the simple use of configuration attributes and access-decision voters which have seen before. We are using a couple lombok annotation here to drastically reduce the boiler plate required in writing a simple data class, auto-magically generating getters and setters along with a few other nice things. Annotations.
