问题描述
我正在跟踪链接 https://github.com/spring-guides/gs-serving-web-content
签出文件后，将gs-serving-web-content/complete导入IDEA，然后运行它.它运行成功，但是如果我按以下方式使用http来访问它，则会失败.
After check out the files, import gs-serving-web-content/complete into IDEA, and run it. It runs successfully, but if I use http as following to access it then it failed.

推荐答案
以下
java.lang.NoClassDefFoundError: org/apache/tomcat/util/log/UserDataHelper
意味着您缺少tomcat-july.jar.
means that you're lacking a tomcat-july.jar.
但是，以下
Caused by: java.util.zip.ZipException: invalid LOC header (bad signature)
表示您的依赖项已损坏.我敢打赌，嵌入式的tomcat依赖项没有正确下载.如果我是您，我将备份并删除.m2\repository\org\apache\tomcat\embed并再次运行该示例，以便它再次下载依赖项
means that you have a corrupted dependency. My bet would be that the embedded tomcat dependencies did not got downloaded properly. If I were you, I would back-up and delete the .m2\repository\org\apache\tomcat\embed and run the example again, so that it downloads the dependencies again
