這篇文章將為大家詳細講解有關基于zTree中Jsp通用動態級聯樹結構是怎么樣的,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
1、categoryTree.html 通用頁面
<link rel="stylesheet" href="/static/plugins/zTree_v3/css/zTreeStyle.css" type="text/css"> <style> /*展示樹狀結構的樣式*/ ul.ztree {position:relative;top: 32px;left:0px;z-index:999;border: 1px solid #617775;background: #f0f7fb;width:220px;height:360px;overflow-y:scroll;overflow-x:auto;display: none} </style> <script type="text/javascript" src="/static/plugins/zTree_v3/js/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="/static/plugins/zTree_v3/js/jquery.ztree.core.js"></script> <SCRIPT type="text/javascript" > var node_id ,node_name; var zTreeObj, setting = { view: { selectedMulti: false //多選選項 }, data:{//定義數據規范 simpleData:{ enable:false,//是否使用簡單的數據結構,本例使用標準json樹狀結構 idKey:'cat_id',//nodeId字段名稱 pIdKey:'parent_id',//parentId字段名稱 rootPId:0 //跟nodeId的值 }, key:{ //字段名稱定義 name:"cat_name",//展示名稱 children:"nodes"//子節點對象 } } }, zTreeNodes = []; //加載動態數據 function loadTree(data){ if(data && data.length>0){ zTreeNodes = data; zTreeObj = $.fn.zTree.init($("#tree"), setting, zTreeNodes); } } $(document).ready(function(){ $.post("/category/getCategoryTree",null,loadTree); }); </SCRIPT> <ul id="tree" class="ztree"></ul>
2、調用方法
<div class="t_text ml10" id="category"> <c:import url="../common/categoryTree.jsp"/> <!--如果是靜態頁面可以使用jquery.load() 方法 --> <input type="hidden" name="cat_id" id="cat_id" value="${pageParam.cat_id }" /> <input placeholder="類別" type="text" name="cat_name" id="cat_name" /> </div>
3.controller
import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; /** * @author liujun * @since 2018/1/18. * 產品分類 */ @Controller @RequestMapping("/category") public class CategoryController { Logger logger = LoggerFactory.getLogger(CategoryController.class); @Autowired CategoryTreeService categoryService; @RequestMapping(value = "/getCategoryTree") @ResponseBody public List<CategoryTree> getCategoryTree(){ logger.info("處理請求:/category/getCategoryTree"); return this.categoryService.getCategoryTree(); } }
4、service接口
import java.util.List; /** * @author liujun * @since 2018/1/18. * 產品類別服務接口 */ public interface CategoryTreeService extends CommonService<CategoryTree,Long>{ /** * 獲取類別樹 * @return List<CategoryTree>商品類別{@link CategoryTree} */ public List<CategoryTree> getCategoryTree(); } import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; import org.springframework.data.domain.Sort; import org.springframework.data.jpa.domain.Specification; import java.io.Serializable; import java.util.Collection; import java.util.List; /** * Created by liujun on 2018/1/22. */ public interface CommonService <E,ID extends Serializable> { public E get(ID id); public E find(ID id); public List<E> getAll(); public Long getTotalCount(); public E save(E entity); public E update(E entity); public void delete(E entity); public void delete(ID id); public void delete(Collection<E> entities); public void flush(); public List<E> findAll(Specification<E> spec); public Page<E> findAll(Pageable pageable); public Page<E> findAll(Specification<E> spec, Pageable pageable); public List<E> findAll(Specification<E> spec, Sort sort); public long count(Specification<E> spec); }
5、service實現
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import javax.annotation.Resource; import java.util.List; /** * @author liujun * @since 2018/1/18. * @see CategoryTreeServiceImpl * 產品類別業務類{@link Service} */ @Service public class CategoryTreeServiceImpl extends CommonServiceImpl<CategoryTree,Long> implements CategoryTreeService { @Resource(name = "baseSqlDaoImpl") CustomBaseSqlDao baseSqlDao; @Autowired CategoryTreeDao categoryTreeDao; @Override public List<CategoryTree> getCategoryTree() { String hql = " select o from CategoryTree o where o.parent_id = 0 order by o.sort_order"; return this.baseSqlDao.queryForList(hql); } @Autowired public void setCategoryDao(CategoryTreeDao categoryTreeDao) { super.setCommonDao(categoryTreeDao); this.categoryTreeDao = categoryTreeDao; } } /** * 基礎Service的定義 * @author Jeff Xu * @since 2015-12-09 * @param <E> * @param <ID> */ public abstract class CommonServiceImpl<E,ID extends Serializable> implements CommonService <E,ID> { protected CommonDao<E,ID> commonDao; public void setCommonDao(CommonDao<E, ID> commonDao) { this.commonDao = commonDao; } public CommonDao<E, ID> getCommonDao() { return commonDao; } /** * 根據ID獲取某個Entity * @param id * @return */ public E get(ID id) { return commonDao.getOne(id); } /** * 根據ID查找某個Entity(建議使用) * @param id * @return */ public E find(ID id) { return commonDao.findOne(id); } /** * 獲取所有的Entity列表 * @return */ public List<E> getAll() { return commonDao.findAll(); } /** * 獲取Entity的總數 * @return */ public Long getTotalCount() { return commonDao.count(); } /** * 保存Entity * @param entity * @return */ public E save(E entity) { return commonDao.save(entity); } /** * 修改Entity * @param entity * @return */ public E update(E entity) { return commonDao.save(entity); } /** * 刪除Entity * @param entity */ public void delete(E entity) { commonDao.delete(entity); } /** * 根據Id刪除某個Entity * @param id */ public void delete(ID id) { commonDao.delete(id); } /** * 刪除Entity的集合類 * @param entities */ public void delete(Collection<E> entities) { commonDao.delete(entities); } /** * 清空緩存,提交持久化 */ public void flush() { commonDao.flush(); } /** * 根據查詢信息獲取某個Entity的列表 * @param spec * @return */ public List<E> findAll(Specification<E> spec) { return commonDao.findAll(spec); } /** * 獲取Entity的分頁信息 * @param pageable * @return */ public Page<E> findAll(Pageable pageable){ return commonDao.findAll(pageable); } /** * 根據查詢條件和分頁信息獲取某個結果的分頁信息 * @param spec * @param pageable * @return */ public Page<E> findAll(Specification<E> spec, Pageable pageable) { return commonDao.findAll(spec, pageable); } /** * 根據查詢條件和排序條件獲取某個結果集列表 * @param spec * @param sort * @return */ public List<E> findAll(Specification<E> spec, Sort sort) { return commonDao.findAll(spec); } /** * 查詢某個條件的結果數集 * @param spec * @return */ public long count(Specification<E> spec) { return commonDao.count(spec); } }
6、dao接口
/** * Created by liujun on 2018/1/22. */ public interface CustomBaseSqlDao { public List<Map<String, Object>> querySqlObjects(String sql, Integer currentPage, Integer rowsInPage); public List<Map<String, Object>> querySqlObjects(String sql); public List<Map<String, Object>> querySqlObjects(String sql, List<Object> params); public List<Map<String, Object>> querySqlObjects(String sql, Object params, Integer currentPage,Integer rowsInPage); public PageModel<Map<String, Object>> querySqlObjects(String sql, String sbCount, Map<String, Object> params, Integer currentPage, Integer rowsInPage); public int getCount(String sql); public List queryForList(String hql, List<Object> params); public List queryByMapParams(String hql, Map<String, Object> params, Integer currentPage,Integer pageSize); public List queryByMapParams(String hql, Map<String, Object> params); public List queryForList(String hql); public PageModel queryForPage(String hql,int currentPage,int pageSize); public PageModel queryForPageWithParams(String hql, String hqlCount, Map<String,Object> params, int currentPage,int pageSize); public PageModel queryForPageWithParams(String hql,Map<String,Object> params, int currentPage,int pageSize); public PageModel queryForPageBySql(String sql,Integer currentPage,Integer pageSize); public PageModel queryForPageBySql(String sql,Map<String,Object> params,Integer currentPage,Integer pageSize); public Long queryCount(String hql, Map<String, Object> params); public Integer queryCountBySql(String sql, Map<String, Object> params); public int executeSql(String sql, List<Object> params); } /** * Created by liujun on 2018/1/19. */ public interface CategoryTreeDao extends CommonDao<CategoryTree,Long>{ } /** * 基礎Dao接口定義 * @since 2015-12-09 */ @NoRepositoryBean public interface CommonDao<E,ID extends Serializable> extends JpaRepository<E,ID>, JpaSpecificationExecutor<E> { }
7、dao實現
