记一次服务启动时bean注入时 Requested bean is currently in creation的问题

发现测试服务器一台muc启动失败，另一台是好的，本地也没问题，报错信息如下：

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;

后来mucAccountLoginController加了段代码

@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;

原先只有一个AuthorizationServerTokenServices需要注入，现在变成两个，如果同时发生注入的时候就会报错。在其中一个要注入的类上上加上@Lazy就好了

@RestController
@RequestMapping(value = "", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
@Api(tags = "Web - 账号登录相关", 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;
