Error creating bean with name 'PiechartAction' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError:org/jfree/data/general/PieDataset 错误信息说PiechartAction这个bean常见失败，是由于在该内中引用的PieDataset找不到类org/jfree/data/general/PieDataset，展开包看看是否含有这个类，如果有可能是jar冲突，相同的删除低版本的jar文件。
