要在Spring Boot项目中集成Apache Shiro框架,可以按照以下步骤进行操作:

  1. 添加依赖:在pom.xml文件中添加Shiro和Spring Boot Shiro相关的依赖。例如:
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring-boot-starter</artifactId>
    <version>1.7.1</version>
</dependency>
  1. 配置Shiro:创建一个Shiro配置类,例如ShiroConfig.java,并使用@Configuration注解进行标注。在这个类中,你可以配置Shiro的各种组件,如SecurityManagerRealmFilter等。例如:
@Configuration
public class ShiroConfig {

    @Bean
    public SecurityManager securityManager(CustomRealm customRealm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(customRealm);
        return securityManager;
    }

    @Bean
    public CustomRealm customRealm() {
        return new CustomRealm();
    }

    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);

        // 配置过滤器链
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/admin/**", "authc");
        filterChainDefinitionMap.put("/**", "anon");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        return shiroFilterFactoryBean;
    }
}

在上面的示例中,CustomRealm是一个自定义的Realm类,用于处理身份验证和授权逻辑。ShiroFilterFactoryBean用于配置过滤器链,定义了哪些URL需要认证和授权。

  1. 自定义Realm:实现org.apache.shiro.realm.AuthorizingRealm接口,创建一个自定义的Realm类。在这个类中,你可以实现doGetAuthenticationInfodoGetAuthorizationInfo方法,分别用于处理身份验证和授权逻辑。例如:
public class CustomRealm extends AuthorizingRealm {

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        // 获取用户名和密码
        String username = (String) token.getPrincipal();
        String password = new String((char[]) token.getCredentials());

        // 查询用户信息
        User user = userService.findByUsername(username);
        if (user == null || !user.getPassword().equals(password)) {
            throw new UnknownAccountException("用户名或密码错误");
        }

        return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName());
    }

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        // 获取用户角色和权限
        String username = (String) principals.getPrimaryPrincipal();
        User user = userService.findByUsername(username);
        List<String> roles = user.getRoles();
        List<String> permissions = user.getPermissions();

        // 创建授权信息对象
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        authorizationInfo.setRoles(roles);
        authorizationInfo.setStringPermissions(permissions);

        return authorizationInfo;
    }
}

在上面的示例中,userService是一个自定义的服务类,用于查询用户信息。

  1. 启用Shiro:在你的Spring Boot主类上添加@EnableShiro注解,以启用Shiro集成。例如:
@SpringBootApplication
@EnableShiro
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

完成以上步骤后,你的Spring Boot项目就成功集成了Apache Shiro框架,并可以进行身份验证和授权操作了。你可以根据具体需求对Shiro进行进一步的配置和扩展。
