本文整理了Java中play.libs.Json.mapper()方法的一些代码示例，展示了Json.mapper()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Json.mapper()方法的具体详情如下：
包路径：play.libs.Json
类名称：Json
方法名：mapper

Json.mapper介绍

[英]Gets the ObjectMapper used to serialize and deserialize objects to and from JSON values. This can be set to a custom implementation using Json.setObjectMapper.
[中]获取用于在JSON值之间序列化和反序列化对象的ObjectMapper。可以使用Json将其设置为自定义实现。setObjectMapper。
