分析：

网上参考drools达人“二师兄”的一篇博客，连接如下：http://blog.csdn.net/wo541075754/article/details/48243403

解决：

方案一：我的drools版本是drools6.0；然后参照上述连接发现是commons-lang 2.x 和 commons-lang 3.x发生冲突导致，然后在drools的应用路径下找到其所加载的包路径，进行删除2.x即可。相对路径如下：../webapps/kie-drools-wb/WEB-INF/lib;另外，除了在drools项目下的jar包冲突，你也应该注意自己本身的项目下是否有同样的jar使用。如有，请三思后进行修改。

方案二：有点取巧；因为我的实体属性是boolean值，我就尝试着假如用string类型去修饰，试着将结果“true”代替为“Y”，“false”代替为“N”，然后就解决了~
