在Weblogic服务器上部署Spring Boot应用程序时出错

Question

由于我在Spring Boot项目中添加了Hateoas依赖项并部署在weblogic Server12c上，因此我面临这个问题

启动ApplicationContext时出错。若要显示条件报告，请在启用“调试”的情况下重新运行应用程序。2020-01-09 14:18:53,591错误org.springframework.boot.diagnostics.loggingfailureanalysisreporter[[STANDBY]executeThread：“3”队列：“weblogic.kernel.default（自调优）”]

应用程序启动失败

描述：

org.springframework.hateoas.config.hateoasconfiguration中方法linkDiscoverers的参数0需要一个bean，但找到了15个：-modelbuilderpluginregistry：在null-modelpropertybuilderpluginregistry中定义：在null-typenameproviderpluginregistry中定义：在null-documentationpluginregistry中定义：在null-apilistingbuilderpluginregistry中定义：在null-operationbuilderpluginregistry中定义类路径资源[org/springframework/hateoas/config/webmvcentitylinksconfiguration.class]中的titylinkspluginregistry

行动：

考虑将其中一个bean标记为@primary，更新使用者以接受多个bean，或者使用@qualifier标识应该使用的bean

Answer 1

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

这意味着有15个方法返回符合HateOasConfiguration的bean。

Spring在列表后面继续：

        - 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]

列表可能不是那么清晰或熟悉，因为其中一些方法可能是由框架定义的。

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

不一定。首先试着看看其他人是否也面临同样的问题。

你可能会在那里找到解决办法。
