spring - Spring 服务中的 Drools XStream

Question

我开始使用 drools ，我想在 spring-boot 服务中使用它，但即使是一个简单的例子，我在 Xstream 上也没有这样的方法错误。我错过了什么？

我面临着类似的问题。该方法是在 xstream v1.4.10 中引入的。

我能够通过 excluding xstream (v1.4.9) 修复它依赖 drools-compiler (v7.6.0.Final)并为 xstream (v1.4.10) 添加单独的依赖项

<dependency>
   <groupId>org.drools</groupId>
   <artifactId>drools-compiler</artifactId>
   <version>7.6.0.Final</version>
   <exclusions>
      <exclusion>
         <groupId>com.thoughtworks.xstream</groupId>
         <artifactId>xstream</artifactId>
      </exclusion>
   </exclusions>
</dependency>

<dependency>
   <groupId>com.thoughtworks.xstream</groupId>
   <artifactId>xstream</artifactId>
   <version>1.4.10</version>
</dependency>
