java - 无法打开嵌套条目“WEB-INF/lib/example.jar”

Question

我有可执行的war文件要运行，我从WEB-INF/lib文件夹中删除了一个.jar文件。再次将相同的 jar 文件添加到相同的路径中，但无法运行 war 文件，出现以下错误

Exception in thread "main" java.lang.IllegalStateException: Failed to get nested archive for entry WEB-INF/lib/test-cts-chk-query-rest-app-1.0.5/com/testcorp/cts/chk/query/rest/app/ClearinghouseQueryRESTController.class at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchive(JarFileArchive.java:108) at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchives(JarFileArchive.java:86) at org.springframework.boot.loader.ExecutableArchiveLauncher.getClassPathArchives(ExecutableArchiveLauncher.java:70) at org.springframework.boot.loader.Launcher.launch(Launcher.java:49) at org.springframework.boot.loader.WarLauncher.main(WarLauncher.java:58) Caused by: java.io.IOException: Unable to open nested jar file 'WEB-INF/lib/test-cts-chk-query-rest-app-1.0.5/com/testcorp/cts/chk/query/rest/app/ClearinghouseQueryRESTController.class' at org.springframework.boot.loader.jar.JarFile.getNestedJarFile(JarFile.java:254) at org.springframework.boot.loader.jar.JarFile.getNestedJarFile(JarFile.java:239) at org.springframework.boot.loader.archive.JarFileArchive.getNestedArchive(JarFileArchive.java:103) ... 4 more Caused by: java.lang.IllegalStateException: Unable to open nested entry 'WEB-INF/lib/test-cts-chk-query-rest-app-1.0.5/com/testcorp/cts/chk/query/rest/app/ClearinghouseQueryRESTController.class'.

有没有办法在gradle项目上解决这个问题？

Answer 1

首先，如果您有一个 gradle 项目，那么您不需要添加外部 Jar，您可以编写一个 gradle 脚本来在程序中使用该 jar/class 文件。

第二件事，如果您刚刚在 Lib 目录中删除并添加了 jar，您需要清理并构建项目一次。
