Java Spring启动-未加载war文件中的静态资源

我使用gradle从一个

Spring启动项目（v1.5.3）

构建了一个war文件，并且我能够使用“java-jar my.war”运行它。当我访问应用程序时，静态资产出现故障，日志中出现以下异常：

java.io.FileNotFoundException:无法将Jar URL解析为绝对值 文件路径，因为它不位于文件系统中： war:file:/BUILD\u DIR/BUILD/libs/my.war*/assets/images/homepage-img1.jpg

如果我打开war（解压），然后使用“java-classpath WEB-INF/lib/*：WEB-INF/classes:”运行它。com.pkg.Application'，一切正常

我想知道我是把我的战争包装错了，还是以一种错误的方式进行的。谢谢你的帮助。谢谢大家!

我最终找到了以下问题：

“spring核心”包“org.springframework.util.ResourceUtils”在4.3.8中进行了修改，这为spring Boot 1.5.3.RELEASE版本引入了一个问题。我将我的Spring Boot降级为1.5.2.RELEASE，Spring dependencies降级为4.3.7.RELEASE，一切正常

谢谢

这是

jar

还是

war

文件？如果它是

war

文件，我不确定

java-jar

如何工作？因为您使用的是SpringBoot，所以它附带了一个嵌入式jetty。在这种情况下，您可以构建为jar文件。看看如何使用Maven或Gradle构建胖jar。您能分享异常的完整堆栈跟踪吗？它是一个war文件，“java-jar”除了加载静态资源外没有任何问题。将stacktrace添加到OP中。我尝试通过spring代码进行调试，失败的地方是将协议作为“file”查找，但代码中的url有“war:file:/path/to/war*/assets/img.png”（它从war开始）。如果（！URL_PROTOCOL_FILE.equals（resourceUrl.getProtocol（））{throw new FileNotFoundException（description+“无法解析为绝对文件路径”+”，因为它不在文件系统中：“+resourceUrl”）；}这在1.5.4版中已修复。
