一、异常描述

通过springframework的srping-mvc框架，并配置freemarker视图渲染后(相关配置脚本实例)，访问后报出“org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.IllegalAccessError: tried to access method freemarker.ext.servlet.AllHttpScopesHashModel.<init>(Lfreemarker/template/ObjectWrapper;Ljavax/servlet/ServletContext;Ljavax/servlet/http/HttpServletRequest;)V from class org.springframework.web.servlet.view.freemarker.FreeMarkerView”异常，如下所示

二、解决办法

1.蒋freemarker的版本由2.3.8调整为2.3.21即可解决问题(相关的jar及pom文件下载freemarker-2.3.21.jar.rar)

<dependency>@b@   <groupId>freemarker</groupId>@b@   <artifactId>freemarker</artifactId>@b@   <version>2.3.8</version>@b@</dependency>

改为

<dependency>@b@   <groupId>freemarker</groupId>@b@   <artifactId>freemarker</artifactId>@b@   <version>2.3.21</version>@b@</dependency>
