  <!-- 配置restful json 解析器 , 用CXF自帶的JSONProvider需要注意以下幾點(diǎn)
  -1、dropRootElement 默認(rèn)為false，則Json格式會(huì)將類名作為第一個(gè)節(jié)點(diǎn)，如{Customer:{"id":123,"name":"John"}}，如果配置為true，則Json格式為{"id":123,"name":"John"}。
  -2、dropCollectionWrapperElement屬性默認(rèn)為false，則當(dāng)遇到Collection時(shí)，Json會(huì)在集合中將容器中類名作為一個(gè)節(jié)點(diǎn)，比如{"Customer":{{"id":123,"name":"John"}}}，而設(shè)置為false，則JSon格式為{{"id":123,"name":"John"}}
  -3、serializeAsArray屬性默認(rèn)為false，則當(dāng)遇到Collecion時(shí)，格式為{{"id":123,"name":"John"}}，如果設(shè)置為true，則格式為[{"id":123,"name":"john"}]，而Gson等解析為后者
