1、错误描述
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/ezmorph/Morpher at net.sf.json.util.CycleDetectionStrategy.<clinit>(CycleDetectionStrategy.java:37) at net.sf.json.JsonConfig.<clinit>(JsonConfig.java:65) at net.sf.json.JSONArray.fromObject(JSONArray.java:105) at com.you.model.ListToJSON.main(ListToJSON.java:29) Caused by: java.lang.ClassNotFoundException: net.sf.ezmorph.Morpher at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 4 more
从“Caused by: java.lang.ClassNotFoundException: net.sf.ezmorph.Morpher”这句可以看出,是缺少jar
3、解决办法
将“ezmorph-1.0.6.jar”复制到lib目录下
