Question

我正在Java8 Spring 4.3.1.RELEASE上运行Wildfly10 RESTful服务，没有任何问题。我已经将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 /杰克逊/数据绑定/ java类型;）LCOM / fasterxml /杰克逊/数据绑定/ ObjectWriter;

Wildfly10与Tomcat8上的版本之间存在一些不兼容问题。

任何建议都表示赞赏。

Answer 1

可能你会得到与WildFly捆绑的Jackson版本。尝试从WildFly使用的配置文件中删除“jaxrs”子系统（默认情况下为standalone.xml）。

Answer 2

<强>解决方案

我通过更新修正了这个：

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

到

<jackson.version>2.8.6</jackson.version>

Wildfly与Tomcat上的rapidxml.jackson版本
