Spring Security is a powerful framework that is used to add security features to Spring applications. It supports easy implementation of authentication and authorization functionalities. Here, we will implement basic login\/logout features.<\/p>\n
3.1 Adding Spring Security Dependency<\/h3>\n
Although this dependency is already included in the dependencies selected from Spring Initializr, you can additionally add the Spring Security dependency in the pom.xml file if needed:<\/p>\n
\n<dependency>\n <groupId>org.springframework.boot<\/groupId>\n <artifactId>spring-boot-starter-security<\/artifactId>\n<\/dependency>\n<\/code><\/pre>\n3.2 Creating the SecurityConfig Class<\/h3>\n
To configure Spring Security, we create the `SecurityConfig` class. This class configures the security filter chain for Spring Security:<\/p>\n
\nimport org.springframework.context.annotation.Bean;\nimport org.springframework.context.annotation.Configuration;\nimport org.springframework.security.config.annotation.web.builders.HttpSecurity;\nimport org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;\nimport org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;\n\n@Configuration\n@EnableWebSecurity\npublic class SecurityConfig extends WebSecurityConfigurerAdapter {\n @Override\n protected void configure(HttpSecurity http) throws Exception {\n http\n .authorizeRequests()\n .antMatchers(\"\/login\", \"\/register\").permitAll() \/\/ Allow access to login and registration pages\n .anyRequest().authenticated() \/\/ All other requests require authentication\n .and()\n .formLogin()\n .loginPage(\"\/login\") \/\/ Set login page\n .permitAll() \/\/ Allow all users to access\n .and()\n .logout()\n .permitAll(); \/\/ Allow logout functionality\n }\n}\n<\/code><\/pre>\n4. Implementing User Registration<\/h2>\n
To implement the registration feature, we will create a User entity and UserRepository. Then we will create a service that saves user information to the database.<\/p>\n
