java - Wildfly 与 Tomcat 上的 fastxml.jackson 版本

Question

我正在 Wildfly10 上使用 Spring 4.3.1.RELEASE 运行 Java8 RESTful 服务，没有任何问题。此后，我已将 Java 项目迁移到 AWS 服务器。此服务器托管 Tomcat 8(Wildfly 不可用)。

我正在使用fasterxml:

<jackson.version>2.4.2</jackson.version>

在 Tomcat 服务器上，我得到:

java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ObjectWriter.forType(Lcom/fasterxml/jackson/databind/JavaType;)Lcom/fasterxml/jackson/databind/ObjectWriter;

Wildfly10 与 Tomcat8 上的版本似乎存在一些不兼容问题。

任何建议表示赞赏。

您可能会获得与 WildFly 捆绑在一起的 Jackson 版本。尝试从 WildFly 使用的配置文件(默认为standalone.xml)中删除“jaxrs”子系统。
