java JsonArray数组遍历组成新的json对象
jsonArray1 =
[{"checked_id":"10002","content_title":"duo1","content":"du11"},{"checked_id":"10002","content_title":"duo1","content":"du12"},{"checked_id":"10002","content_title":"duo2","content":"du21"},{"checked_id":"10002","content_title":"duo2","content":"du22"}]
遍历成功的数组为：
"key_property_list" : [
{
"key" : "duo1",
"value_list" : [
{
"value" : "du11"
},
{
"value" : "du12"
}
]
},{
"key" : "duo2",
"value_list" : [
{
"value" : "du21"
},
{
"value" : "du22"
}
]
}
]

创建array2，遍历array1，拿出每项的title的值去与array里面的所有key相比，若有相同则往value_list里面添加，若没有相同的则new一个对象var obj = {"value_list":[]};然后将对应的值添加进去。

不能正常返回字符串，老是以对象方式

已解决，我也找不到更好的办法了
