该博客主要讨论了Freemarker在加载版本时遇到的问题，导致出现`incompatibleImprovements`设置错误。错误信息表明配置的版本不兼容，这可能会破坏FreeMarker的升级。解决方案是将`new Configuration(Configuration.VERSION)`的写法替换为`new Configuration(Configuration.DEFAULT_INCOMPATIBLE_IMPROVEMENTS)`。对于不熟悉英文文档的读者，提供了具体的参考链接以获取更多信息。

freemark错误：

freemarker.log._JULLoggerFactory$JULLogger.error DefaultObjectWrapper.incompatibleImprovements was set to the object returned by Configuration.getVersion(). That defeats the purpose of incompatibleImprovements, and makes upgrading FreeMarker a potentially breaking change. Also, this probably won't be allowed starting from 2.4.0. Instead, set incompatibleImprovements to the highest concrete version that's known to be compatible with your application.

产生原因：系统加载freemark版本存在问题

解决方案：

 
Configuration cfg = new Configuration(Configuration.getVersion());


替换以下写法


Configuration cfg = new Configuration(Configuration.DEFAULT_INCOMPATIBLE_IMPROVEMENTS);

具体参考：

The "incompatible improvements" setting - Apache FreeMarker Manual

里面全是英文看不懂
