Spring Boot 1.2.x with Spring Security 4

Simple Example

Simple example of using Spring Security 4 with Spring Boot 1.2.x with Maven.

The key is to use the Spring Security Starter and override the spring-security.version property. For example:

<properties>
	<!-- ... -->

	<spring-security.version>4.0.1.RELEASE</spring-security.version>
</properties>

<dependencies>
	<!-- ... -->

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-security</artifactId>
	</dependency>
</dependencies>

If you are migrating from Spring Security 3.2.x, then the same migration steps are involved as a standard Spring Security 3.2.x to Spring Security 4.x migration.

Thymeleaf

If you are using Thymeleaf, then you need to ensure to use

<dependency>
	<groupId>org.thymeleaf.extras</groupId>
	<artifactId>thymeleaf-extras-springsecurity4</artifactId>
	<version>2.1.2.RELEASE</version>
</dependency>

then you need to expose the SpringSecurityDialect as a @Bean

import org.springframework.context.annotation.*;
import org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect;

@Configuration
public class SecurityConfig {

	@Bean
	public SpringSecurityDialect securityDialect() {
		return new SpringSecurityDialect();
	}
}
