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;
