jackson中的ObjectMapper是否线程安全，能否单例生成全局使用
请大神帮忙解释下，有测试用例就更好了

官方网站有答案，参考 http://wiki.fasterxml.com/JacksonFAQ Is ObjectMapper thread-safe? Short answer: yes Long answer: yes, as long as you always configure instance before use, and do not call configure methods during operation (or synchronize such calls appropriately). Usually it is better to construct separate mapper instance if configurations differ in any case. Further: it is beneficial to use just one instance (or small number of instances) for data binding; many optimizations for reuse (of symbol tables, some buffers) depend on ObjectMapper instances being reused.
