在 Weblogic 服务器上部署 Spring Boot 应用程序时出错

Question

自从我将 Hateoas 依赖项添加到我的 Spring boot 项目并部署在 weblogic server 12c 上后，我就面临这个问题

启动 ApplicationContext 时出错。显示条件报告 在启用“调试”的情况下重新运行您的应用程序。 2020-01-09 14:18:53,591 错误 org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter [[待机] ExecuteThread: '3' 用于队列： 'weblogic.kernel.Default (self-tuning)']

应用程序启动失败

说明：

org.springframework.hateoas.config.HateoasConfiguration 中方法linkDiscoverers 的参数0 需要一个 单个 bean，但找到了 15 个： - modelBuilderPluginRegistry：定义为null - modelPropertyBuilderPluginRegistry：定义为null - typeNameProviderPluginRegistry：在 null 中定义 - documentationPluginRegistry: 定义为 null - apiListingBuilderPluginRegistry：定义为空 - operationBuilderPluginRegistry：定义为null - parameterBuilderPluginRegistry：定义为null -expandParameterBuilderPluginRegistry：定义为null - resourceGroupingStrategyRegistry：定义为null - operationModelsProviderPluginRegistry：在 null 中定义 - defaultsProviderPluginRegistry：在 null 中定义 - pathDecoratorRegistry：在 null 中定义 - relProviderPluginRegistry：由类路径资源中的“relProviderPluginRegistry”方法定义 [org/springframework/hateoas/config/HateoasConfiguration.class] - linkDiscovererRegistry：定义为空 - entityLinksPluginRegistry：由类路径资源中的“entityLinksPluginRegistry”方法定义 [org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]

行动：

考虑将其中一个 bean 标记为 @Primary，更新消费者以接受多个 bean，或者使用 @Qualifier 来识别 应该吃的豆子

Answer 1

春天告诉你问题

org.springframework.hateoas.config.HateoasConfiguration required a single bean,
    but 15 were found:

这意味着有 15 种方法返回适合 HateoasConfiguration 的 bean。

那些混蛋是谁？

春天在列表之后继续：

        - modelBuilderPluginRegistry: defined in null
        - modelPropertyBuilderPluginRegistry: defined in null
        - typeNameProviderPluginRegistry: defined in null
        - documentationPluginRegistry: defined in null
        - apiListingBuilderPluginRegistry: defined in null
        - operationBuilderPluginRegistry: defined in null
        - parameterBuilderPluginRegistry: defined in null
        - expandedParameterBuilderPluginRegistry: defined in null
        - resourceGroupingStrategyRegistry: defined in null
        - operationModelsProviderPluginRegistry: defined in null
        - defaultsProviderPluginRegistry: defined in null
        - pathDecoratorRegistry: defined in null
        - relProviderPluginRegistry: defined by method 'relProviderPluginRegistry' 
             in class path resource
             [org/springframework/hateoas/config/HateoasConfiguration.class]
        - linkDiscovererRegistry: defined in null
        - entityLinksPluginRegistry: defined by method 'entityLinksPluginRegistry'
             in class path resource
             [org/springframework/hateoas/config/WebMvcEntityLinksConfiguration.class]

该列表可能并不那么清晰或熟悉，因为其中一些方法可能是由框架定义的。

那么可以做些什么呢？

Spring 提出了一个解决方案：

 Action:

    Consider marking one of the beans as @Primary,
    updating the consumer to accept multiple beans,
    or using @Qualifier to identify the bean that should be consumed

是否意味着我需要重新配置我的@Beans？

不一定。先试试看if someone else faced the same problem。

您可以在那里找到解决方案。
