由于"注入自动连接的依赖项失败",无法启动嵌入式Tomcat

Question

我是Java的新手,目前负责管理新的应用程序.我试图启动应用程序,它失败,出现以下错误:

TL; DR:阅读Spring给你的错误.

让我们把错误系统地通过它:

首先我们有Exception in thread "main"- 除了由于"无法启动嵌入式容器"而导致状态爆炸之外,这并没有告诉我们任何事情.

好的,是什么造成的,让我们进入下一个级别:

Caused by: org.springframework.boot.context.embedded.EmbeddedServletContainerException: Unable to start embedded Tomcat

好的,那里不多.让我们进入一个新的水平:

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,现在我们到了某个地方 - WebSecurityConfiguration由于自动装配问题我们无法创建,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无法自动使用该方法,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 - 所以它无法自动装配它无法创建的方法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,不AuthenticationProvider.为什么不？

Could not autowire field: private com.thinkbiganalytics.auth.AuthenticationService com.thinkbiganalytics.auth.AuthServiceAuthenticationProvider.authenticationService

啊,不authenticationService.为什么不？

Could not autowire field: com.thinkbiganalytics.datalake.podium.restclient.PodiumRestClient

啊,不PodiumRestClient.为什么不？

Could not autowire field: private boolean com.thinkbiganalytics.datalake.podium.restclient.PodiumRestClientImpl.useHttps

好吧,它无法创建PodiumRestClientImpl它,因为它无法自动装配boolean useHttps.为什么不？

Failed to convert value of type 'java.lang.String' to required type 'boolean'; nested exception is java.lang.IllegalArgumentException: Invalid boolean value [${podium.useHttps}]

所以它无法自动装配,PodiumRestClientImpl.useHttps因为它无法将String值转换${podium.useHttps}为a boolean.很公平.

因此,似乎您在自动装配配置值时未正确使用SpEL,或者您尚未PropertySource配置为将占位符解析为配置值.
