?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]at org.codehaus.jackson.map.JsonMappingException.from(JsonMappingException.java:163)at org.codehaus.jackson.map.deser.StdDeserializationContext.mappingException(StdDeserializationContext.java:198)at org.codehaus.jackson.map.deser.BeanDeserializer.deserializeUsingCreator(BeanDeserializer.java:565)at org.codehaus.jackson.map.deser.BeanDeserializer.deserialize(BeanDeserializer.java:365)at org.codehaus.jackson.map.ObjectMapper._readMapAndClose(ObjectMapper.java:2391)at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java:1591)at com.acxiom.rest.controller.HelloWorldController.hygiene(HelloWorldController.java:52)

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。
