Spring Boot整合shiro后导致@Cacheable、@Transactional等注解失效的问题

# 一、问题描述 #

*  Springboot整合shiro前，service里的@Cacheable、@Transactional等注解都正常使用。
 *  整合shiro之后，UserRealm类里自动注入的service中的注解失效

UserRealm代码如下:

public class UserRealm extends AuthorizingRealm { 
        private static final Logger LOGGER = LoggerFactory.getLogger(UserRealm.class);
        /** * 这种情况下SysUserService里缓存、事务等注解失效 */
        @Autowired
        private SysUserService sysUserService;
    
        //省略其他代码
    }

SysUserService代码如下：

@Service
    public class SysUserService { 
        @Autowired
        private SysUserMapper userMapper;
    
        @Cacheable(cacheNames = "users", key = "'sysuser:'+#userName")
        public SysUser findByUserName(String userName) {
            return userMapper.findByUserName(userName);
        }
    }

# 二、解决方法 #

**在UserRealm自动注入service时，添加@Lazy注解延迟注入**，如下：

public class UserRealm extends AuthorizingRealm { 
        private static final Logger LOGGER = LoggerFactory.getLogger(UserRealm.class);
        /** * 添加@Lazy注解延迟注入 */
        @Autowired
        @Lazy
        private SysUserService sysUserService;
    
        /** * 添加@Lazy注解延迟注入 */
        @Autowired
        @Lazy
        private SysPermissionService sysPermissionService;
    
        //省略其他代码
    }
