?遇到的异常： server端转化json失败：

org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of com.pojo.Phone out of START_ARRAY token
 at [Source: java.io.StringReader@55afbf49; line: 1, column: 1]

Debug了一下程序，发现传进来的json字符串是数组格式的：

[{"phoneNumber":"0513 XXXXX","phoneType":"1","countryCode":"1","geoOption":"1","defaultOption":"1","geoLat":"1","geoLong":"1"}]

?

果断修改了Server端代码：

?

	ObjectMapper mapper = new ObjectMapper();
	Phone phone = mapper.readValue(phoneObject, Phone[].class)[0];

?

问题解决。
