Spring Security XML Configuration Last Updated : 05 Apr, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report Spring Security is a robust and highly customizable framework that provides authentication and authorization for Java applications. While Java-based configuration is widely used today, XML-based configuration remains an important approach for legacy applications and projects requiring declarative security.In this article, we will learn how to implement Spring Security XML Configuration in a Spring MVC web application. We will cover setting up dependencies, configuring security settings in XML, defining controllers, and securing URLs using role-based authentication.Implementation: Here we will be creating a Spring MVC web application and adding xml-based configuration.Steps to Configure Spring Security Using XML in a Spring MVC ApplicationStep 1: Create a Maven Web ApplicationCreate a maven webapp project, we are using Eclipse IDE for creating this project. While creating a Maven project, select the archetype for this project as maven-archetype-webapp. Enter the group id and the artifact id for your project and click 'Finish.'Project Structure:After creating the project your project structure would look something like this:Step 2: Add Dependencies in pom.xml FileOnce the project is created, update the pom.xml file with the necessary dependencies, including:spring-webmvcspring-security-webspring-security-corespring-security-configjavax.servlet-apipom.xml: XML <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.gfg</groupId> <artifactId>SpringSecurityXmlConfig</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>SpringSecurityXmlConfig Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.3.16</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.security/spring-security-web --> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>5.8.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.security/spring-security-core --> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>5.8.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.security/spring-security-config --> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>5.8.4</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> </dependencies> <build> <finalName>SpringSecurityXmlConfig</finalName> <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin> <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>3.2.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> </plugins> </pluginManagement> </build> </project> Step 3: Configure web.xml (Deployment Descriptor)The web.xml file acts as a bridge between the application and Spring Security.
