Beanquery is a Java tool library that converts objects to maps. Supports selecting some attributes in the bean, sorting the results, and querying by criteria. It can be used not only for top-level objects, but also for child objects.

The use of beanquery is very simple and straightforward, and the example code is as follows:

/static import Beanqueryimport static cn.jimmyshi.beanquery.beanquery.*;//use Select, from, where, order BY, DESC, and ASC to assemble a query, Then execute the Execute method to get the result. list<map<string, object>> result = Select ("Price,name,mainauthor.name as Mainauthorname")    . From ( bookcollection)    . Where (        //for books name is Book2 or starts with Book1        anyOf (            value ("Name", StartsWith ( "Book1"),            value ("Name", Is ("Book2")))        ,        //for books price between (53,65)        AllOf (            value ("Price") , GreaterThan (53d)),            value ("Price", LessThan (65d))).    ("name"). Desc ()    . Execute ();

in the example above, the contents of Bookcollection are as follows (in JSON format)

[{"Price": 55.55, "name": "Book1", "Mainauthor": {"name": "Book1-mainauthor", "address": {"Addre SS ":" Shenzhen Guangdong China "," postcode ":" 518000 "}," BirthDate ":" 1982-01-30t14:52:39 "}}, {" Price ": 52.55," name ":" Book12 "," Mainauthor ": {" name ":" Book1-mainauthor "," address ": {" Address ":" She Nzhen Guangdong China "," postcode ":" 518000 "}," BirthDate ":" 1982-01-30t14:52:39 "}}, {" Price ": 5 3.55, "name": "Book13", "Mainauthor": {"name": "Book13-mainauthor", "address": {"Address": "Shenzhen G    Uangdong China "," postcode ":" 518000 "}," BirthDate ":" 1982-01-30t14:52:39 "}}, {" Price ": 60.0,  "Name": "Book14", "Mainauthor": {"name": "Book14-mainauthor", "address": {"Address": "Shenzhen Guangdong China "," postcode ":" 518000 "}," BirthDate ":" 1982-01-30t14:52:39 "}}, {" Price ": 50.55," name " : "Book15", "MainauthoR ": {" name ":" Book1-mainauthor "," address ": {" Address ":" Shenzhen Guangdong China "," postcode ":" 5180      XX "}," BirthDate ":" 1982-01-30t14:52:39 "}}, {" Price ": 77.77," name ":" Book3 "," Mainauthor ": {      "Name": "Book3-mainauthor", "address": {"Address": "Shenzhen Guangdong China", "postcode": "518005" }, "BirthDate": "1982-01-30t14:52:39"}}, {"Price": 66.66, "name": "Book2", "Mainauthor": {"name"      : "Book2-mainauthor", "address": {"Address": "Shenzhen Guangdong China", "postcode": "518005"}, "BirthDate": "1982-01-30t14:52:39"}}]

after execution, the contents of result are as follows (in JSON format)

[  {    "price": 60.0,    "name": "Book14",    "Mainauthorname": "Book14-mainauthor"  },  {    " Price ": 53.55,    " name ":" Book13 ",    " Mainauthorname ":" Book13-mainauthor "  },  {    " price ": 55.55,    "name": "Book1", "    mainauthorname": "Book1-mainauthor"  }]
