Spring Boot (1.2.7) web应用(响应SSL请求)在Intellij IDEA中运行良好。
为了从命令行运行,构建JAR文件时会导致启动错误。
org.springframework.context.ApplicationContextException:
无法启动嵌入式容器;
嵌套异常是
org.springframework.context.ApplicationContextException: 由于缺少EmbeddedServletContainerFactory bean,无法启动EmbeddedWebApplicationContext。
问题
- 如何避免这个错误?
- 如果需要声明EmbeddedServletContainerFactory,如何使其ServletContainer处理我的Controller的请求?
尝试的解决方案
按照错误提示添加EmbeddedservletContainerFactory。现在可以从JAR启动项目,但是像在IntelliJ中那样请求不会被Controller接收。
这是我Application.class的代码,在添加EmbeddedServletContainerFactory之后。

return connector;
}
catch (Exception ex) {
throw new IllegalStateException("can't access keystore: [" + "keystore"
+ "] or truststore: [" + "keystore" + "]", ex);
}
}
}
注意事项
Spring Boot(Web)应用程序在从Intellij IDEA运行时表现良好,响应https请求只需在application.properties中添加几行附加代码:
security.require-ssl=true
server.port=8443
server.ssl.key-store=src/main/resources/private/keystore
server.ssl.key-store-password=changeit
server.ssl.key-password=changeit
我使用以下命令在命令行中启动JAR文件:
java -Dspring.profiles.active=production -Dkeystore.file=file:///$PWD/keystore -jar diabetes-spring.jar
这样做启动JAR没有错误,但https网络请求(在Intellij中正常工作)只返回Apache/tomcat 404 "所请求的资源不可用"。
编辑
使用-Ddebug运行JAR会输出以下信息(为了不让找不到配置文件application.properties/application/application-production.properties的DEBUG消息显得不相关,我省略了它们)。 . ____ _ __ _ _
