关于jackson中时间字符串的转换

 

"yyyy-MM-dd'T'HH:mm:ss.SSSZ"
 "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
 "EEE, dd MMM yyyy HH:mm:ss zzz"
 "yyyy-MM-dd"

当尸实体中存在Date类型，但是json字符串中是字符串类型

只支持以上几种格式否则报错

 

org.codehaus.jackson.map.JsonMappingException: Can not construct instance of java.util.Date from String value '19802-22T12:00:00.000-0800': not a valid representation (error: Can not parse date "19802-22T12:00:00.000-0800": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd"))
