在Spring Boot项目中整合Shiro和Redis，可以通过以下步骤实现：
- 引入相关依赖：
<!-- Shiro -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>你的Shiro版本</version>
</dependency>
<!-- Redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>- 配置Shiro和Redis：
@Configuration
public class ShiroConfig {
@Bean
public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
RedisCacheManager redisCacheManager = new RedisCacheManager();
redisCacheManager.setRedisManager(redisManager(redisConnectionFactory));
return redisCacheManager;
}
@Bean
public RedisManager redisManager(RedisConnectionFactory redisConnectionFactory) {
RedisManager redisManager = new RedisManager();
redisManager.setHost("localhost"); // Redis服务器地址
redisManager.setPort(6379); // Redis服务器连接端口
return redisManager;
}
@Bean
public DefaultWebSecurityManager securityManager(CacheManager cacheManager) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 设置realm
securityManager.setRealm(myRealm());
// 注入cacheManager
securityManager.setCacheManager(cacheManager);
return securityManager;
}
@Bean
public MyRealm myRealm() {
return new MyRealm();
}
// 其他Shiro配置...
}- 创建自定义Realm：
public class MyRealm extends AuthorizingRealm {
@Autowired
private UserService userService;
@Autowired
private RoleService roleService;
@Autowired
private PermissionService permissionService;
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 获取当前登录用户
User user = (User) principals.getPrimaryPrincipal();
// 获取用户的角色和权限信息
Set<String> roles = roleService.getRolesByUserId(user.getId());
