Spring Security Example

The spring-boot-starter-parent provides you all maven defaults required for any spring project. Since we are developing a web application, we also need to add spring-boot-starter-web dependency and also we need to include spring-boot-starter-security to secure this web application If you notice, we did not provide any version for specific components. You just need to provide version no.(1.5.3.RELEASE) for spring boot. Step 3: Create a package named “org.arpit.java2blog.springboot” create a controller class named “HelloWorldController.java”. @EnableWebSecurity annotation is used to enable spring security for this webapp. AuthroizeRequest().addMatchers() method is used to configure pattern for request.For example: If http request url has pattern /hello*(hello.jsp,helloworld.html), it will be accessed to ROLE_ADMIN only.

Spring Security Project using Java Configuration. Spring Framework added Java configuration support in Spring 3.1. In Spring Security, Java configuration was added to Spring Security 3.2 that allows us to configure Spring Security without writing single line of XML. Here, we will create an example that implements Spring Security and configured without using XML. Spring security Overview Spring security is the highly customizable authentication and access-control framework. This is the security module for securing spring applications. But, this can also be used for non-spring based application with few extra configurations to enable the security features. Spring Security is a framework that focuses.

We have hardcoded username(java2blog) and password(java123) using inMemoryAuthentication(), so if user provides correct credential for admin then only he will be able to access helloworld.html. Step 4: Create a package named “org.arpit.java2blog” create a class named “SpringBootHelloWorldApplication.java”. We have just added @SpringBootApplication and it does all the work. Let’s understand more about this annotation. @SpringBootApplication is an annotation that adds all of the following: @Configuration makes the class as a source of bean definitions for the application context.

@EnableAutoConfiguration enables Spring boot to add beans presents in classpath setting and various property setting. Normally you would add @EnableWebMvc for a Spring MVC application, but Spring Boot adds it automatically when it sees spring-webmvc on the classpath. This flags the application as a web application and activates key behaviors such as setting up a DispatcherServlet.

If specific packages are not defined, scanning will occur from the package of the class that declares this annotation. Step 5: Create a property file named application.properties as below and put it in src/main/resoures. Spring.mvc.view.prefix: /WEB-INF/ spring.mvc.view.suffix:.jsp Above two properties are very much similar to used in springmvc-dispatcher-servlet.xml in. Step 7: Modify index.jsp as below.
