Arrays 基于Java的Mongodb复杂查询

我是全新的mongodb，但需要用java进行一些复杂的查询

{
        "_id" : ObjectId("558d4887c33598835a7f5ee3"),
        "username" : "shree",
        "detail1" : "d1",
        "detail2" : "d2",
        "detail3" : "d3",
        "detail4" : [
                      {
                       "firstname":"Mary",
                       "lastname":"Smith",
                       "zipcode":"12345"
                      },
                      {
                       "firstname":"John",
                       "lastname":"Henry",
                       "zipcode":"54624"
                      },
                      {
                        "firstname":"Jacob",
                        "lastname":"Tell",
                        "zipcode":"19283"
                       },
                       {
                        "firstname":"William",
                        "lastname":"Dirk",
                        "zipcode":"15999"
                       }
                    ],

       "detail5" : "d5",

}

现在我想要一个这样的查询

1.勾选“用户名”，如果匹配，请在“详情4”中添加更多内容

2.选中“username=shree”和“zipcode=54624”，并应返回

  {
        "_id" : ObjectId("558d4887c33598835a7f5ee3"),
        "username" : "shree",
        "detail1" : "d1",
        "detail2" : "d2",
        "detail3" : "d3",
        "detail4" : {
                       "firstname":"John",
                       "lastname":"Henry",
                       "zipcode":"54624"
                     },

       "detail5" : "d5",

}

   {
      "firstname":"William",
      "lastname":"Dirk",
      "zipcode":"15999"
   }

3.选中“username=shree”和“zipcode=15999”，并应删除

  {
        "_id" : ObjectId("558d4887c33598835a7f5ee3"),
        "username" : "shree",
        "detail1" : "d1",
        "detail2" : "d2",
        "detail3" : "d3",
        "detail4" : {
                       "firstname":"John",
                       "lastname":"Henry",
                       "zipcode":"54624"
                     },

       "detail5" : "d5",

}

   {
      "firstname":"William",
      "lastname":"Dirk",
      "zipcode":"15999"
   }

数据库应保留以下内容：

{
        "_id" : ObjectId("558d4887c33598835a7f5ee3"),
        "username" : "shree",
        "detail1" : "d1",
        "detail2" : "d2",
        "detail3" : "d3",
        "detail4" : [
                      {
                       "firstname":"Mary",
                       "lastname":"Smith",
                       "zipcode":"12345"
                      },
                      {
                       "firstname":"John",
                       "lastname":"Henry",
                       "zipcode":"54624"
                      },
                      {
                        "firstname":"Jacob",
                        "lastname":"Tell",
                        "zipcode":"19283"
                       }
                    ],

       "detail5" : "d5",

}
