zTree控件加载权限信息的保存

当我们根据角色id,获取该角色拥有的所有的权限,然后使用zTree控件进行展示,这个zTree控件可以对当前角色的权限进行维护,那么我们如何保存该角色的权限信息呢?

JSP页面

<div style="margin:1px;padding-left:45px;">
	            	<input type="hidden" id="editAuthRoleId" value="${editAuthRoleId }"/>
		       	<input type="button" onclick="addRoleAuth()" value="保存" class="btn btn-primary">
	            </div>

JS代码

/**
 * 保存角色菜单权限
 */
function addRoleAuth(){
	var roleid = $("#editAuthRoleId").val();
	if(roleid==""){
		showMessageDialog("保存失败，请选择角色进行编辑");
		return false;
	}
	
	nodes=zTree.getCheckedNodes(true);
	var authIds="";
	for(var i=0;i<nodes.length;i++){
		if(i+1<nodes.length){
			authIds+=nodes[i].id+",";
		}else{
			authIds+=nodes[i].id;
		}
	}
	
	$.ajax({
		url: webContext+"/platform/role/editRoleAuth/"+roleid,
		type: 'POST',
		dataType:"json",
		data:{
			authIds:authIds
		},
		error: function(){
			showMessageDialog("请求错误,保存失败!");
		},
		success: function(result){
			if(result.success){
				showMessageDialog("角色权限保存成功!",function(){
					getAuthTreeByRole(roleid);
				});
			}else{
				showMessageDialog("角色权限保存失败!!");
			}
		}
	});
}

Controller

    /**
     * 
      * 方法说明：编辑角色权限信息
      * @param roleid 角色id
      * @param authIds 权限id字符串，逗号分隔
      * @return 
      * @author wangchaojie　2015年9月25日
      *
     */
    @RequestMapping(value = "/editRoleAuth/{roleid}")
    @ResponseBody
    public AjaxResult editRoleAuth(@PathVariable("roleid") long roleid, @RequestParam String authIds) {
        AjaxResult ajaxResult = AjaxResult.errorResult("");
        if(roleid == 0){
            return ajaxResult;
        }
        try{
            List<Long> authIdList = StrUtils.splitToListLong(authIds, ",");
            roleAuthService.editRoleAuth(roleid,authIdList);
        }catch(Exception e){
            e.printStackTrace();
            return ajaxResult;
        }
        return AjaxResult.successResult();
    }

Service层

	/**
	 * 
	  * 方法说明：编辑角色权限信息
	  * @param roleid 角色id
	  * @param authIdList 权限idList
	  * @author wangchaojie　2015年9月25日
	  *
	 */
	@Transactional
    public void editRoleAuth(long roleid, List<Long> authIdList) {
	    roleAuthDao.deleteByRoleidFk(roleid);
        for(Long authId : authIdList){
            RoleAuth roleAuth = new RoleAuth(authId,roleid);
            roleAuthDao.save(roleAuth);
        }
    }

Dao层,持久层使用spring data jpa

@NoRepositoryBean
public interface CrudRepository<T, ID extends Serializable> extends Repository<T, ID> {

	/**
	 * Saves a given entity. Use the returned instance for further operations as the save operation might have changed the
	 * entity instance completely.
	 * 
	 * @param entity
	 * @return the saved entity
	 */
	<S extends T> S save(S entity);
