Spring Boot JAR - 缺少EmbeddedServletContainerFactory
Spring Boot（1.2.7）Web应用程序（响应SSL请求）在Intellij IDEA上运行良好。
构建JAR工件以从命令行运行，启动时抛出错误
org.springframework.context.ApplicationContextException:
Unable to start embedded container;
nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
问题
- 如何避免此错误？
- 如果我需要声明一个EmbeddedServletContainerFactory，我怎么能让它的ServletContainer处理我的Controller的请求？
尝试解决方案
根据错误请求添加了EmbeddedservletContainerFactory。项目现在从JAR开始，但Controller没有像从IntelliJ运行那样收到请求。
在 添加EmbeddedServletContainerFactory后，我的Application.class看起来像是
package org.coursera.diabetes;
import com.j256.ormlite.dao.Dao;
import com.j256.ormlite.support.ConnectionSource;
import diabetes.common.model.*;

}
@Bean

public EmbeddedServletContainerFactory servletContainer(@Value("${keystore.file}") Resource keystoreFile) {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
//factory.setPort(8443);
String absoluteKeystoreFile = "";
try {
absoluteKeystoreFile = keystoreFile.getFile().getAbsolutePath();
logger.info(String.format("******** keystore: %s", absoluteKeystoreFile));
} catch (IOException e) {
e.printStackTrace();
}
tomcat.addAdditionalTomcatConnectors(createSslConnector(absoluteKeystoreFile));
return tomcat;
}
private Connector createSslConnector(String absKeystoreFile) {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
try {
connector.setScheme("https");
connector.setSecure(true);
connector.setPort(8443);
protocol.setSSLEnabled(true);
protocol.setKeystoreFile(absKeystoreFile);
protocol.setKeystorePass("changeit");
protocol.setKeyAlias("tomcat");
return connector;
}
catch (Exception ex) {
throw new IllegalStateException("can't access keystore: [" + "keystore"
+ "] or truststore: [" + "keystore" + "]", ex);
}
}
}
注释
Spring Boot（Web）应用程序在Intellij IDEA上运行良好，响应https请求，而无需在application.properties中执行任何其他操作：
security.require-ssl=true
server.port=8443
server.ssl.key-store=src/main/resources/private/keystore
server.ssl.key-store-password=changeit
server.ssl.key-password=changeit
要从命令行启动JAR工件，我使用：
java -Dspring.profiles.active=production -Dkeystore.file=file:///$PWD/keystore -jar diabetes-spring.jar
JAR启动时没有错误，但https Web请求（从Intellij工作）只返回Apache / tomcat 404 “请求的资源不可用”。
的修改
使用-Ddebug运行JAR会输出以下信息（我省略了所有未找到配置文件的DEBUG消息application.properties / application / application-production.properties，这些消息似乎并不相关）

在IntelliJ IDEA - 项目结构 - 工件 - 可用元素中，所有Gradle依赖库都需要提取到输出根，以便Spring Boot应用程序的JAR从java命令行执行中正常运行
将JAR工件更改为此后，我可以构建JAR并从命令行JVM运行它。
要在HTTPS / SSL端口8443上运行的默认TomcatEmbeddedServletContainerFactory，请指定等于application.properties中所需的java命令行参数。
即
java -jar your-spring.jar --security.require-ssl=true --server.port=8443 --server.ssl.key-store=keystore --server.ssl.key-store-password=changeit --server.ssl.key-password=changeit
