spring - 由于“自动连接依赖项注入(inject)失败”而无法启动嵌入式Tomcat

我是Java新手，目前负责管理新应用程序。我正在尝试启动应用程序及其失败，并出现以下错误：

最佳答案

TL; DR：读取Spring给您的错误。

让我们来处理错误并系统地解决它：

首先，我们有Exception in thread "main"-除了“由于无法启动嵌入式容器”导致状态炸毁之外，它什么也没告诉我们。

好的，是什么原因导致的，让我们进入下一个层次：

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

好吧，那儿不多了。让我们进入下一个层次：

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，现在到了某处-由于自动装配问题，我们无法创建WebSecurityConfiguration，但是那是什么问题呢？

Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.setFilterChainProxySecurityConfigurer(org.springframework.security.config.annotation.ObjectPostProcessor,java.util.List)

嗯，好的，Spring无法自动连接该方法，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'

嗯，好的-因此它无法自动连接无法创建formBasedWebSecurityConfiguration的方法。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？

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

啊，没有authenticationService。为什么不？

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

啊，没有PodiumRestClient。为什么不？

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？

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

因此它无法自动连接PodiumRestClientImpl.useHttps，因为它无法将值String的${podium.useHttps}转换为boolean。很公平。

因此，似乎是您在自动装配配置值时未正确使用SpEL或未配置PropertySource来将占位符解析为配置值。
