由于 "Injection of autowired dependencies failed"，无法启动嵌入式 Tomcat
Unable to start embedded Tomcat due to "Injection of autowired dependencies failed"
我是 Java 的新手，目前负责管理一个新应用程序。我正在尝试启动应用程序，但失败并出现以下错误：

TL;DR：阅读 Spring 给你的错误。
让我们找出错误并系统地解决它：

首先我们有 Exception in thread "main" - 除了由于 "Unable to start embedded container".
而导致状态爆炸外，这并没有告诉我们任何信息
好的，是什么原因造成的，让我们进入下一个阶段：
Caused by: org.springframework.boot.context.embedded.EmbeddedServletContainerException: Unable to start embedded Tomcat
好吧，没有更多了。让我们进入下一个阶段：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Injection of autowired dependencies failed
好的，现在我们取得了进展 - 由于自动装配问题，我们无法创建 WebSecurityConfiguration，但那是什么问题？
Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.setFilterChainProxySecurityConfigurer(org.springframework.security.config.annotation.ObjectPostProcessor,java.util.List)
啊，好吧，Spring 无法自动装配该方法，为什么不呢？
nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'formBasedWebSecurityConfiguration'
啊，好吧 - 所以它不能自动装配那个方法它不能创建一个 formBasedWebSecurityConfiguration。为什么不？
Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.security.authentication.AuthenticationProvider
啊，没有 AuthenticationProvider。为什么不呢？
Could not autowire field: private com.thinkbiganalytics.auth.AuthenticationService com.thinkbiganalytics.auth.AuthServiceAuthenticationProvider.authenticationService
啊，没有 authenticationService。为什么不呢？
Could not autowire field: com.thinkbiganalytics.datalake.podium.restclient.PodiumRestClient
啊，没有 PodiumRestClient。为什么不呢？
Could not autowire field: private boolean com.thinkbiganalytics.datalake.podium.restclient.PodiumRestClientImpl.useHttps
好的，它无法创建 PodiumRestClientImpl，因为它无法自动装配 boolean useHttps。为什么不呢？
Failed to convert value of type 'java.lang.String' to required type 'boolean'; nested exception is java.lang.IllegalArgumentException: Invalid boolean value [${podium.useHttps}]
因此它无法自动装配 PodiumRestClientImpl.useHttps，因为它无法将值为 ${podium.useHttps} 的 String 转换为 boolean。很公平。
因此，似乎您在自动装配配置值时没有正确使用 SpEL，或者您没有配置 PropertySource 来将占位符解析为配置值。
