大家好，有人可以帮我理解为什么会出现这个问题......

基本上，我已经使用 Maven 创建了一个 REST WS，并构建了一个 WAR 文件以部署到 Glassfish 5 中，当我访问其中一个端点时出现错误。

否则，如果我将相同的 WAR 部署到 Tomcat 9 中，则对端点的相同调用运行良好。

部署过程毫不费力，REST 端点在两者中都可以使用。

两个 AS 的 JAVA_HOME 相同，配置为在 Java 1.8 中运行。

但是在对端点的特定调用中，会引发此错误：

Tomcat您说和之间观察到的行为存在差异Glassfish。

如果我们查看日志输出，我们会看到有 java.lang.AbstractMethodError抛出。

如果我们查看Oracle 文档，我们可以看到它在...

当应用程序尝试调用抽象方法时抛出。通常，这个错误会被编译器捕获；如果自上次编译当前执行的方法以来某些类的定义发生了不兼容的更改，则此错误只会在运行时发生。

实际上，这是因为您的应用程序中的某些依赖版本不兼容。您可以在此处看到一个场景示例。

如果我们仔细查看错误消息，我们可以看到以下内容

java.lang.AbstractMethodError: com.fasterxml.jackson.databind.ser.std.ReferenceTypeSerializer.withResolved(Lcom/fasterxml/jackson/databind/BeanProperty;Lcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/ databind/JsonSerializer;Lcom/fasterxml/jackson/databind/util/NameTransformer;Lcom/fasterxml/jackson/annotation/JsonInclude$Include;)Lcom/fasterxml/jackson/databind/ser/std/ReferenceTypeSerializer;

所以，好吧……为什么会发生？Spring Boot 应用程序Jackson用于序列化和反序列化，通常在嵌入式Tomcat. Glassfish 上的某些东西似乎非常不同，它必须提供一些jars，这导致了这种不兼容。

最简单的解决方案似乎是使用Glassfish6.0 的下一个版本......希望它包含一些更现代的 jar，它们与 Spring Boot 的 jackson 兼容。

否则，我认为，您需要更改Jackson Glassfish正在使用的 v 5.0 版本...以使其与 Spring Boot 兼容。

或者更改JacksonSpringBoot 使用的版本，使其与 Glasshfish 版本兼容。

这给出了解决策略。如果您还有其他问题，请在此答案的评论中发布。
