Requested bean is currently in creation: Is there an unresolvable circular r

  今天在用springboot打包成war包,准备部署到tomcat时,发现采用maven的package命令时,老是失败,报错Requested bean is currently in creation: Is there an unresolvable circular r,经过一番操作后,解决了问题。原因出在存在循环注入的问题,现在贴代码说明情况

  我的项目是采用springboot、spring security,mybatis框架做成的,我在srevice层有两个实现类,分别是StuServiceImpl和FileServiceImpl,下面贴出关键代码部分

@Service
@Slf4j
public class StuServiceImp implements StuService{

    @Resource
    private StuMapper stuMapper;//自己写的mapper

    @Resource
    private UserDao userDao;//框架自带的mapper

    @Resource
    private RoleDao roleDao;

    @Resource
    private BCryptPasswordEncoder passwordEncoder;//该类是spring security框架用来给密码加密用的

 

 

@Service
public class FileServiceImpl implements FileService {

   private static final Logger log = LoggerFactory.getLogger("adminLogger");

   @Value("${files.path}")
   private String filesPath;

   @Resource
   private FileInfoDao fileInfoDao;

   @Resource
   private StuMapper stuMapper;

   @Resource
   private CardMapper cardMapper;

   @Resource
   private UserDao userDao;

   @Resource
   private RoleDao roleDao;

   @Resource
   private BCryptPasswordEncoder passwordEncoder;

 

从以上可以看到,这两个实现类都注入了BCryptPasswordEncoder,导致了打包失败

解决办法是加@Lazy,如下图所示:

@Resource
@Lazy
private BCryptPasswordEncoder passwordEncoder;
