解决json字符串转java bean 并包含日期且日期为空

1.解决json转java bean，并成功读取date

JsonConfig jsonConfig = new JsonConfig();

JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[] { "yyyy-MM-dd HH:mm:ss", "yyyy-MM-dd HH:mm", "yyyy-MM-dd" }));

jsonConfig.registerJsonValueProcessor(java.util.Date.class, new DateJsonValueProcessor());
jsonConfig.setPropertySetStrategy(propertySetStrategy);
jsonConfig.setRootClass(objectClass);
return (List) JSONArray.toCollection(JSONArray.fromObject(json), jsonConfig);

2.解决json对象中日期为空，删除日期属性

$.each(areaDetails, function(i) {    
var area = areaDetails[i];
if(area["adEnddate"] == undefined || area["adEnddate"] == ""){
delete area["adEnddate"]; 
}
});
