Spring boot Jsp / 不同模块中的标签
Spring boot Jsp / Tag in different module
我正在努力实现以下目标：
Webapp 模块，其中包含来自 https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-web-jsp 示例的默认 Spring 启动 类。样本本身工作正常。
共享模块，其中包含 jsp 要在 webapp 模块中使用的顶级域名和标签。
如果标签文件位于 webapp 模块中，它会正确显示标签。如果标记文件位于共享模块中，则可以找到 tld 文件，但无法找到 custom.tag，例外情况是：
org.apache.jasper.JasperException: File [/WEB-INF/tags/custom.tag] not found

这是测试项目：https://github.com/Gunthervg/spring-boot-jsp-tags => SampleWebJspApplicationTests 也因此失败。
有人知道我该如何解决这个问题吗？
编辑：
可能与 https://github.com/spring-projects/spring-boot/issues/8324
有关
我最后做了以下事情：
根据 https://github.com/spring-projects/spring-boot/issues/8324 将标签从 src/main/resources/META-INF/tags 移动到 src/main/resources/META-INF/resources/WEB-INF/tags。
已将包装更改为 war
使用包含标签的 maven-war-plugin 并将它们放在 /WEB-INF:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<webResources>
<resource>
<directory>../shared/src/main/resources/META-INF/resources</directory>
</resource>
</webResources>
</configuration>
</plugin>

这是测试项目：https://github.com/Gunthervg/spring-boot-jsp-tags => SampleWebJspApplicationTests 也因此失败。
有人知道我该如何解决这个问题吗？
编辑： 可能与 https://github.com/spring-projects/spring-boot/issues/8324
有关我最后做了以下事情：
根据 https://github.com/spring-projects/spring-boot/issues/8324 将标签从 src/main/resources/META-INF/tags 移动到 src/main/resources/META-INF/resources/WEB-INF/tags。
已将包装更改为 war
使用包含标签的 maven-war-plugin 并将它们放在 /WEB-INF:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<webResources>
<resource>
<directory>../shared/src/main/resources/META-INF/resources</directory>
</resource>
</webResources>
</configuration>
</plugin>
