在Nutz里我这样写，意义何在？
弱弱的问下各路大侠，如下在nutz中的一个mvc写法的意义何在？
部门信息的Bean
import java.util.List;
import org.nutz.dao.entity.annotation.*;
/**
* 部门信息bean
*/
@Table("t_department")
public class Department {
@Id
@Column("id")
private int id;// 机构ID
@Column("name")
private String name;// 机构名称
@Column("code")
private String code;// 机构编号
@Column("pid")
private int pid;// 父机构ID
@One(field = "pid", target = Department.class)
private Department pdepartment;// 上级机构信息
@Column("remark")
private String remark;// 备注
@Column("orderid")
private String orderid;// 排序号
@Column("deleted")
private int deleted;//是否已删除
@ManyMany(from = "userid", relation = "t_role_department", target = Role.class, to = "roleid")
private List<Role> roles;//关联的角色
//省略get和set....
}
部门信息的service接口
public interface DepartmentService {
/**
* 已删除部门
*/
public List<Department> list();
/**
* 查询所有部门(已删除、未删除)
*/
public List<Department> list(boolean haveDeleted);
/**
* 分页查询接口
*/
public Map<String, Object> list(int page, int pagesize, String orderfield,
String ordertype, String where, boolean haveDeleted);
/**
* 新增
* @return
*/
public Department insert(Department department);
/**
* 更新
*/
public void update(Department department);
/**
* 批量删除(ID以逗号分割)
*/
public void remove(String ids);
/**
* 根据部门ID查询
*/
public Department view(Long id);
/**
* 根据部门名称查询
*/
public Department fetchByName(String name);
/**
* 清除
*/
public void clear(String ids);
}
部门信息的接口实现
@InjectName
@IocBean(fields={"dao"})
public class DepartmentServiceImpl extends IdEntityService<Department>
implements DepartmentService {
/**
* 查询所有部门
*
* @param haveDeleted
* 是否含已删除
* @return
*/
public List<Department> list(boolean haveDeleted) {
if (haveDeleted) {
return query(null, null);
} else {
return query(Cnd.where("deleted", "=", 0), null);
}
}
/**
* 分页查询所有部门
*
* @param page
* 每页数量
* @param pagesize
* 页数
* @param orderfield
* 排序字段
* @param ordertype
* 排序方式
* @param where
* 查询where条件
* @param haveDeleted
* 是否含已删除
* @return
*/
public Map<String, Object> list(int page, int pagesize, String orderfield,
String ordertype, String where, boolean haveDeleted) {
if (pagesize < 1) {
pagesize = 10;
}
// 创建分页对象
Pager pager = dao().createPager(page, pagesize);
Map<String, Object> resultMap = new HashMap<String, Object>();
if (pager != null) {
pager.setRecordCount(dao().count(Department.class,haveDeleted?null:Cnd.where("deleted", "=", 0)));
resultMap.put("Total", pager.getRecordCount());
}else{
resultMap.put("Total", 0);
}
resultMap.put("Rows", query(CommonWhere.getWhereCnd(where, haveDeleted), pager));
return resultMap;
}
/**
* 查询已删除部门
*
* @return
*/
public List<Department> list() {
return query(Cnd.where("deleted", "=", 1), null);
}
/**
* 更新
*
* @param department
*/
public void update(Department department) {
dao().update(department);
}
/**
* 新增
*
* @param department
*/
public Department insert(Department department) {
return dao().insertLinks(department, "pdepartment");
}
/**
* 根据部门ID查询
*
* @param id
* @return
*/
public Department view(Long id) {
return dao().fetchLinks(fetch(id), "pdepartment");
}
/**
* 根据部门名称查询
*
* @param name
* @return
*/
public Department fetchByName(String name) {
return fetch(Cnd.where("name", "=", name));
}
/**
* 根据ID批量删除部门（逻辑删除）
*/
@Override
public void remove(String ids) {
dao().update(Department.class, Chain.make("deleted", 1),
Cnd.where("id", "IN", ids));
}
/**
* 根据ID批量清除部门
*/
@Override
public void clear(String ids) {
dao().clear(Department.class, Cnd.where("id", "IN", ids));
}
}
部门信息的Module,只贴一个方法看下
@InjectName("departmentModule")
@At("/Department")
public class DepartmentModule{
//日志
private static final Log log = Logs.get();
//部门信息服务类
private DepartmentService departmentService;
/**
* * 部门信息集合
* @param page 页码
* @param pagesize 分页数据大小
* @param sortname 排序字段
* @param sortorder 排序方式：asc desc
* @param Where 查询条件 格式:
* {"op":"and","rules":[
* {"op":"like",
* "field":"text_fenleiname","value":"123","type":"string"}
* ]
* }
* @return JSON格式的数据 例如：{"Rows":[{...},{...}],"Total":10}
*/
@At("/DepartmentList")
@Ok("json:{ignoreNull:false}")
public Object list( @Param("page") int page ,
@Param("pagesize") int pagesize,
@Param("sortname")String sortname,
@Param("sortorder")String sortorder,
@Param("where")String where){
Map<String, Object> rMap = departmentService.list(page, pagesize, sortname, sortorder, where, true);
log.debug(Json.toJson(rMap));
return rMap;
}
/**
* 部门列表页
* @param currentid 当前部门ID
* @param request
* @return
*/
@At("/ShowDepartmentList")
@Ok("jsp:jsp.system.dep.deplist")
public Object showDepartmentList(@Param("id")String currentid,HttpServletRequest request){
if( Strings.isBlank(currentid) ){
currentid = "-1";
}
request.setAttribute("pid", currentid);
return null;
}
/**
* 用户组操作页
* @param currentid 当前部门ID
* @param isview 是否是查看状态
* @param request
* @return
*/
@At("/ShowDepartmentDetail")
@Ok("jsp:jsp.system.dep.depdetail")
public Object showDepartmentDetail(@Param("id")String currentid,@Param("isview")String isview,HttpServletRequest request){
if( Strings.isBlank(currentid) ){
currentid = "";
}
request.setAttribute("id", currentid);
request.setAttribute("isview", isview);
return null;
}
}
IOC的配置（mvc.js）
var ioc = {
departmentService : {
type : "com.ds.service.system.impl.DepartmentServiceImpl",
fields : {
dao : {
refer : 'dao'
}
}
},
departmentModule : {
type : "com.ds.module.system.DepartmentModule",
fields : {
departmentService : {
refer : 'departmentService'
}
}
}
}
