Spring Boot - 创建名为“云”的 bean 时出错：当前正在创建请求的 bean：是否存在无法解析的循环引用？

Question

我正在使用 Spring Integration 项目开发 SpringBoot。在升级我的应用程序时，我收到以下错误（仅在关键云上而不是本地） -

在上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为“cloudDataBaseConfiguration”的bean时出错：通过字段“cloud”表示的依赖关系不满足：创建名为“cloudMultiHttpSecurityConfig”的bean时出错：通过字段'ldapProvider'表示的不满足的依赖关系：创建在类路径资源[com/fidintl/bs/addcash/config/CloudMultiHttpSecurityConfig.class]中定义的名称为'ldapProvider'的bean时出错：通过方法'ldapProvider'参数表示的不满足的依赖关系0：错误创建在类路径资源 [com/fidintl/bs/addcash/config/CloudMultiHttpSecurityConfig.class] 中定义的名称为“iamClient”的 bean：通过方法“iamClient”参数表示的不满足依赖项 0：创建名称为“cloud”的 bean 时出错：请求的 bean当前正在创建：是否存在无法解析的循环引用？嵌套异常是 org.springframework.beans.factory.BeanCurrentlyInCreationException：创建名为“云”的 bean 时出错：当前正在创建请求的 bean：是否存在无法解析的循环引用？嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在类路径资源 [com/fidintl/bs/addcash/config/CloudMultiHttpSecurityConfig.class] 中定义名称为“iamClient”的 bean 创建时出错：通过方法“iamClient”表达的依赖关系不满足参数 0：创建名为“云”的 bean 时出错：当前正在创建请求的 bean：是否存在无法解析的循环引用？嵌套异常是 org.springframework.beans.factory.BeanCurrentlyInCreationException：创建名为“云”的 bean 时出错：当前正在创建请求的 bean：是否存在无法解析的循环引用？嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在类路径资源 [com/fidintl/bs/addcash/config/CloudMultiHttpSecurityConfig.class] 中定义的名称为“ldapProvider”的 bean 创建时出错：通过方法“ldapProvider”表达的依赖关系不满足参数 0：在类路径资源 [com/fidintl/bs/addcash/config/CloudMultiHttpSecurityConfig.class] 中定义的名称为“iamClient”的创建 bean 时出错：通过方法“iamClient”参数表示的不满足依赖项 0：创建名称为“cloud”的 bean 时出错'：请求的 bean 当前正在创建中：是否存在无法解析的循环引用？嵌套异常是 org.springframework.beans.factory.BeanCurrentlyInCreationException：创建名为“云”的 bean 时出错：当前正在创建请求的 bean：是否存在无法解析的循环引用？

我的配置类 -

    @Configuration
@EnableWebSecurity
@Order(Ordered.HIGHEST_PRECEDENCE)
@Profile("cloud")
public class CloudMultiHttpSecurityConfig extends WebSecurityConfigurerAdapter {

    private static final Logger LOGGER = LoggerFactory.getLogger(CloudMultiHttpSecurityConfig.class);
    @Autowired
    private AuthenticationProvider ldapProvider;

    @Autowired
    private Environment env;

    @Bean
    public Cloud cloud() {
        return new CloudFactory().getCloud();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(ldapProvider);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().fullyAuthenticated();
        http.httpBasic();
        http.csrf().disable();
    }

    @Bean
    public AuthenticationProvider ldapProvider(IAMClient iamClient, Cloud cloud) {
        IamLdapServiceInfo iamServiceInfo = (IamLdapServiceInfo) cloud.getServiceInfo("ldap-provider-info");
        return new AdvLdapAuthProvider(iamServiceInfo, new IAMAuthorityProvider(iamClient));
    }

    @Bean
    public IAMClient iamClient(Cloud cloud) throws Spml2Exception {
        WebServiceInfo serviceInfo = (WebServiceInfo) cloud.getServiceInfo("iam-client-info");
        IAMClient iamClient = new IAMClient(new Spml2Client(serviceInfo.getUri()), serviceInfo.getAppName(), serviceInfo.getUserName(), serviceInfo.getPassword());
        return iamClient;
    }

    @Bean
    public SonUrlService sonataServiceInfo(Cloud cloud) {
        LOGGER.info("Inside sonataServiceInfo Bean, type of serviceInfoBean :" + cloud.getServiceInfo("SonUrlService" + env.getProperty("ups_envn")).getClass());
        return (SonUrlService) cloud.getServiceInfo("SonUrlService" + env.getProperty("ups_envn"));
    }

    @Bean
    public QueueConnectionFactoryServiceInfo mqServiceInfo(Cloud cloud) {
        LOGGER.info("Inside QueueConnectionFactoryServiceInfo Bean, type of mqServiceInfo :" + cloud.getServiceInfo("QueueConnectionFactory_" + env.getProperty("ups_envn")).getClass());
        return (QueueConnectionFactoryServiceInfo) cloud.getServiceInfo("QueueConnectionFactory_" + env.getProperty("ups_envn"));
    }

    @Bean
    public QueueNamesServiceInfo queueNamesServiceInfo(Cloud cloud) {
        return (QueueNamesServiceInfo) cloud.getServiceInfo("QueueNames_" + env.getProperty("ups_envn"));
    }

}

pom.xml -

    <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.RELEASE</version>
    <relativePath />
    </parent>

仅当我将其推送到关键云时，此问题才会出现在本地。

你可以试试这样吗？通过 cloud() 方法直接访问云依赖。

@Configuration
@EnableWebSecurity
@Order(Ordered.HIGHEST_PRECEDENCE)
@Profile("cloud")
public class CloudMultiHttpSecurityConfig extends WebSecurityConfigurerAdapter {

    private static final Logger LOGGER = LoggerFactory.getLogger(CloudMultiHttpSecurityConfig.class);
    @Autowired
    private AuthenticationProvider ldapProvider;

    @Autowired
    private Environment env;

    @Bean
    public Cloud cloud() {
        return new CloudFactory().getCloud();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(ldapProvider);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().fullyAuthenticated();
        http.httpBasic();
        http.csrf().disable();
    }

    @Bean
    public AuthenticationProvider ldapProvider(IAMClient iamClient) {
        IamLdapServiceInfo iamServiceInfo = (IamLdapServiceInfo) cloud().getServiceInfo("ldap-provider-info");
        return new AdvLdapAuthProvider(iamServiceInfo, new IAMAuthorityProvider(iamClient));
    }

    @Bean
    public IAMClient iamClient() throws Spml2Exception {
        WebServiceInfo serviceInfo = (WebServiceInfo) cloud().getServiceInfo("iam-client-info");
        IAMClient iamClient = new IAMClient(new Spml2Client(serviceInfo.getUri()), serviceInfo.getAppName(), serviceInfo.getUserName(), serviceInfo.getPassword());
        return iamClient;
    }

    @Bean
    public SonUrlService sonataServiceInfo() {
        LOGGER.info("Inside sonataServiceInfo Bean, type of serviceInfoBean :" + cloud().getServiceInfo("SonUrlService" + env.getProperty("ups_envn")).getClass());
        return (SonUrlService) cloud().getServiceInfo("SonUrlService" + env.getProperty("ups_envn"));
    }

    @Bean
    public QueueConnectionFactoryServiceInfo mqServiceInfo() {
        LOGGER.info("Inside QueueConnectionFactoryServiceInfo Bean, type of mqServiceInfo :" + cloud().getServiceInfo("QueueConnectionFactory_" + env.getProperty("ups_envn")).getClass());
        return (QueueConnectionFactoryServiceInfo) cloud().getServiceInfo("QueueConnectionFactory_" + env.getProperty("ups_envn"));
    }

    @Bean
    public QueueNamesServiceInfo queueNamesServiceInfo() {
        return (QueueNamesServiceInfo) cloud().getServiceInfo("QueueNames_" + env.getProperty("ups_envn"));
    }

}
