Spring Boot (2.0.0.BUILD-SNAPSHOT) 应用程序无法从 Jetty 启动

Question

我想启动一个 Spring Boot 应用程序，但由于以下原因无法启动：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

我以前从未见过这样的错误，研究它不会导致任何可行的解决方案。

有人知道这里发生了什么吗？

Answer 1

原因：java.lang.SecurityException： 类 "javax.servlet.http.HttpSessionIdListener" 的签名者信息与同一包中其他类的签名者信息不匹配

这意味着您的类路径中有多个javax.servlet.http.HttpSessionIdListener(并且其中一个或多个位于已签名的 jar 文件中)。

清理你的依赖关系，确保你只有一个servlet-api jar。

由于您使用的是 Jetty 9.4.6，因此central.maven.org上的 servlet-api 3.1 jar 坐标是 ...

compile 'javax.servlet:javax.servlet-api:3.1.0'

如何列出所有带有类的罐子

创建一个类以转储您感兴趣的类的位置。 这是作为 junit 测试用例创建的，因此它可以在与您的项目相同的 gradle 依赖项中运行。

import java.io.IOException;
import java.net.URL;
import java.util.Enumeration;
import javax.servlet.http.HttpSessionIdListener;
import org.junit.Test;
public class ClasspathTest
{
@Test
public void testJavaServlet() throws IOException
{
ClassLoader cl = this.getClass().getClassLoader();
String classAsResource = HttpSessionIdListener.class.getName().replace('.','/') + ".class";
Enumeration<URL> urls = cl.getResources(classAsResource);
System.out.printf("Looking for: %s%n",classAsResource);
while (urls.hasMoreElements())
{
URL url = urls.nextElement();
System.out.printf("Found: %s%n",url.toExternalForm());
}
}
}
