java中关于json字符串的处理求助

Question

java中关于json字符串的处理求助：如下数据：{"name":"王大锤","age":"28","city":"杭州市","relation":"{"a":"peter","b":"tom","c":"jack"}","lover":"jenny"}这样的数据json对象中存放了对象，在json字符串转换json对象时，就会格式报错。我的解决就是把它单独拿出来处理，原来的字符串中替换为空字符串，如下：{"name":"王大锤","age":"28","city":"杭州市","relation":"","lover":"jenny"}现在的问题是如何在其中把 {"a":"peter","b":"tom","c":"jack"} 替换为 "".求助大神们，。。。

转成json对象，然后relation属性赋值为""jiu就可以了，操作json推荐用fastjson.jar
