Bean类

@SearchBean(tables="user u, role r", where="u.role_id = r.id", autoMapTo="u") 
public class User {private Long id;        // 用户ID（u.id）private String name;    // 用户名（u.name）private int age;        // 年龄（u.age）private int roleId;     // 角色ID（u.role_id）@DbField("r.name")      // 指明这个属性来自 role 表的 name 字段private String role;        // 角色名（r.name）// Getter and Setter ...
}@RestController
@RequestMapping("/user")
public class UserController {@Autowiredprivate MapSearcher mapSearcher;  // 注入检索器（由 bean-searcher-boot-starter 提供）@GetMapping("/index")public SearchResult<Map<String, Object>> index(HttpServletRequest request) {// 这里咱们只写一行代码return mapSearcher.search(User.class, MapUtils.flat(request.getParameterMap()));}}

示例：

public class controllerDemo{@GetMapping("/index")public SearchResult<Map<String, Object>> index(Integer page, Integer size,String sort, String order, String name, Integer roleId,@RequestParam(value = "name-op", required = false) String name_op,@RequestParam(value = "name-ic", required = false) Boolean name_ic,@RequestParam(value = "age-0", required = false) Integer age_0,@RequestParam(value = "age-1", required = false) Integer age_1,@RequestParam(value = "age-op", required = false) String age_op) {Map<String, Object> params = MapUtils.builder().field(Employee::getName, name).op(name_op).ic(name_ic).field(Employee::getAge, age_0, age_1).op(age_op).field(Employee::getRoleId, roleId).orderBy(sort, order).page(page, size).build();return mapSearcher.search(User.class, params);}}

请求json示例：


{"dataList": [           // 用户列表，默认返回第 0 页，默认分页大小为 15 （可配置）{ "id": 1, "name": "Jack", "age": 25, "roleId": 1, "role": "普通用户" },{ "id": 2, "name": "Tom", "age": 26, "roleId": 1, "role": "普通用户" },...],"totalCount": 100       // 用户总数
}{"dataList": [           // 用户列表，默认返回第 0 页（只包含 id,name,role 字段）{ "id": 1, "name": "Jack", "role": "普通用户" },{ "id": 2, "name": "Tom", "role": "普通用户" },...],"totalCount": 100       // 用户总数
