JSON需要导入的jar包

要使用JSON除了要导入众所周知的json-lib-2.1.jar、json-lib-2.2.3-jdk15.jar两个包，还有导入其他一堆包，哪怕弄一个简单的JSONObject demoJson = JSONObject.fromObject(message);也得导入，要时缺了其中一个，必然报错。

需要导入：commons-beanutils-1.7.0.jar

综上，想用一个最简单的JSON也得导入以下的七个包：

json-lib-2.1.jar
json-lib-2.2.3-jdk15.jar
commons-lang-2.3.jar
ezmorph-1.0.6.jar
commons-logging-1.0.4.jar
commons-collections-3.2.jar
commons-beanutils-1.7.0.jar

伤不起啊！
