記一次服務啟動時bean注入時 Requested bean is currently in creation的問題

發現測試服務器一台muc啟動失敗，另一台是好的，本地也沒問題，報錯信息如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mucAccountLoginController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerEndpointsConfiguration': Unsatisfied dependency expressed through field 'configurers'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'pcAuthorizationServerConfig': Unsatisfied dependency expressed through field 'authenticationManager'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through field 'formAuthenticationConfig'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'formAuthenticationConfig' defined in URL [jar:file:/home/rockysaas/muc/rockysaas-provider-muc.jar!/BOOT-INF/lib/rockysaas-security-core-1.0.jar!/com/rockysaas/security/core/authentication/FormAuthenticationConfig.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pcAuthenticationSuccessHandler': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'defaultAuthorizationServerTokenServices': Requested bean is currently in creation: Is there an unresolvable circular reference?

原因是原先有

public class PcAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {

    @Resource
    private ObjectMapper objectMapper;

    @Resource
    private ClientDetailsService clientDetailsService;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Resource
    private MucAccountService mucAccountService;

    @Resource
    private MucPlatformMapper mucPlatformMapper;

 @Resource private AuthorizationServerTokenServices authorizationServerTokenServices;

后來mucAccountLoginController加了段代碼

@RestController

public class MucAccountLoginController extends BaseController {

    @Resource
    private MucLoginService mucLoginService;
    @Resource
    private MucAccountTokenService mucUserTokenService;
    @Resource
    private ClientDetailsService clientDetailsService;
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Resource
    private MdcApplicationFeignApi mdcApplicationFeignApi;

 @Resource private AuthorizationServerTokenServices authorizationServerTokenServices;

原先只有一個AuthorizationServerTokenServices需要注入，現在變成兩個，如果同時發生注入的時候就會報錯。在其中一個要注入的類上上加上@Lazy就好了

@RestController
@RequestMapping(value = "", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
@Api(tags = "Web - 賬號登錄相關", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public class MucAccountLoginController extends BaseController {

    @Resource
    private MucLoginService mucLoginService;
    @Resource
    private MucAccountTokenService mucUserTokenService;
    @Resource
    private ClientDetailsService clientDetailsService;
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Resource
    private MdcApplicationFeignApi mdcApplicationFeignApi;

    @Resource
 @Lazy private AuthorizationServerTokenServices authorizationServerTokenServices;
