/**
 * 映射规则
 * 1. source 代表源集合以json path表示的值
 * 2. target 代表目标集合以json path表示的key
 *
 * 映射的过程是将 源集合中以source为key的value赋值到目标集合以target为key的值上
 * 如：
 * 集合 input {"key1": "value1"} context {"key1": "value2"}
 * 其中规则为:
 *  - source: 'key1'
 *    target: 'key3'
 *映射结果为:
 * 集合 input {"key1": "value1"} context {"key1": "value2", "key3": "value1"}
