启动应用程序时，如何在没有任何异常的情况下使用FOP和Spring Boot？

使用ApachFop在Java中从XML创建PDF时遇到问题

当Spring加载上下文（从开始）时，我得到一个java.io.FileNotFoundException：

我做错了什么？ 也许我应该使用另一个库来创建PDF。

我认为有些事情与gradle的依赖关系不符。

你没有做错任何事。类路径上有一个jar（来自Xalan），清单中有一个

类路径

条目，指向一些不存在的jar。可以说，这个罐子是错的

Tomcat正在尝试在启动应用程序时查找JSP标记库定义（TLD）。它警告您，它无法找到一些罐子，因此无法扫描它们

警告是良性的，因此您可以选择忽略它们。但这可能不是很令人满意

或者，您可以将Tomcat的TLD扫描配置为跳过带有错误清单的jar。在Spring Boot中，您可以使用

server.tomcat.additional tld skip patterns

属性配置：

以逗号分隔的附加模式列表，这些模式与TLD扫描要忽略的JAR相匹配。模式中可以使用特殊的“？”和“*”字符来分别匹配一个且仅匹配一个字符和零个或多个字符

该值应该类似于

xalan-*.jar
