json-lib-2.4.jar Bug,json字符串中value为"[value]"结构时,解析为数组,不会解析成字符串
使用json-lib.jar 2.4进行json字符串转换为对象时发现一个bug。贴下测试代码:
<dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.12</version> </dependency>
public class Test { public static void main(String[] args) { String json = "{'user':[ {'name':'zs', 'score':'[0-100]'}, " + "{'name':'zs', 'score':'[0-100]'} ]}"; test_json_lib(json); test_fastjson(json); } public static void test_json_lib(String json){ net.sf.json.JSONObject obj = net.sf.json.JSONObject.fromObject(json); System.out.println("json-lib====="+obj.toString()); } public static void test_fastjson(String json){ com.alibaba.fastjson.JSONObject obj = com.alibaba.fastjson.JSONObject.parseObject(json); System.out.println("fastjson====="+obj); } }
输出结果:
json-lib====={"user":[{"name":"zs","score":["0-100"]},{"name":"zs","score":["0-100"]}]} fastjson====={"user":[{"name":"zs","score":"[0-100]"},{"name":"zs","score":"[0-100]"}]}
我测试了使用json-lib和阿里的fastjson,结果如上:发现json-lib把score的value当成了数组(本来是个字符串"[0-100]"),fastjson转换正常。
