包路径：org.boon.json.ObjectMapper
类名称：ObjectMapper
方法名：writeValueAsString

ObjectMapper.writeValueAsString介绍

[英]Method that can be used to serialize any Java value as a String. Functionally equivalent to calling #writeValue(Writer,Object) with java.io.StringWriterand constructing String, but more efficient.
[中]方法，该方法可用于将任何Java值序列化为字符串。在功能上相当于用java调用#writeValue（Writer，Object）。伊奥。StringWriter和构造字符串，但效率更高。
