xml小白笔记 。。。。。。。
<sql id="wDishesColumns">
a.id AS "id",
a.pid AS "pid",
a.name AS "name",
a.photo AS "photo",
a.price AS "price",
a.classification AS "classification",
a.create_by AS "createBy.id",
a.create_date AS "createDate",
a.update_by AS "updateBy.id",
a.update_date AS "updateDate",
a.remarks AS "remarks",
a.del_flag AS "delFlag",
b.name AS "wFoodClassification.name"
</sql> <sql id="wDishesJoins">
LEFT JOIN w_food_classification b ON b.id=a.pid
</sql>
left join 关联查询 关联字段 需要查找什么就在sql里面列出来 在获取
xml 跟dao 跟service 跟entity 跟controller 一个方法对应一个方法
<div class="control-group">
<label class="control-label">照片:</label>
<div class="controls">
<!--<form:input path="photo" htmlEscape="false" maxlength="" class="input-xlarge "/>-->
<form:hidden id="nameImage" path="photo" htmlEscape="false" maxlength="" class="input-xlarge"/>
<sys:ckfinder input="nameImage" type="images" uploadPath="/photo" selectMultiple="false" maxWidth="" maxHeight=""/>
</div>
</div>
从服务器里添加照片代码
<c:forEach items="${page.list}" var="wDishes">
<tr>
<td><a href="${ctx}/dis/wDishes/form?id=${wDishes.id}">
${wDishes.name}
</a></td>
<td>
<img src="${wDishes.photo}" height="100" width="100"/>
</td>
<td>
${wDishes.price}
</td>
<td>
${wDishes.wFoodClassification.name} </td>
<td>
<fmt:formatDate value="${wDishes.updateDate}" pattern="yyyy-MM-dd HH:mm:ss"/>
</td>
<td>
${wDishes.remarks}
</td>
<shiro:hasPermission name="dis:wDishes:edit"><td>
<a href="${ctx}/dis/wDishes/form?id=${wDishes.id}">修改</a>
<a href="${ctx}/dis/wDishes/delete?id=${wDishes.id}" onclick="return confirmx('确认要删除该菜名吗?', this.href)">删除</a>
</td></shiro:hasPermission>
</tr>
</c:forEach>
foreach 里面显示的属性 可以自己修改需要什么取出来
<div class="control-group">
<label class="control-label">分类:</label>
<div class="controls">
<form:select path="wFoodClassification.id" class="input-xxlarge">
<form:options items="${find}" itemLabel="name" itemValue="id" htmlEscape="false"/>
</form:select>
</div>
</div>
获取items 用下拉框格式显示出来
<form:form id="searchForm" modelAttribute="wDishes" action="${ctx}/dis/wDishes/" method="post" class="breadcrumb form-search">
<input id="pageNo" name="pageNo" type="hidden" value="${page.pageNo}"/>
<input id="pageSize" name="pageSize" type="hidden" value="${page.pageSize}"/>
<ul class="ul-form">
<li><label>名字:</label>
<form:input path="name" htmlEscape="false" maxlength="10" class="input-medium"/>
</li>
<li class="btns"><input id="btnSubmit" class="btn btn-primary" type="submit" value="查询"/></li>
<li class="clearfix"></li>
</ul>
</form:form>
jeesite自动生成的查询有错误的话 是controller方法里面没有取出来
在controller里面model取出来就好了
@RequiresPermissions("dis:wDishes:view")
@RequestMapping(value = {"list", ""})
public String list(WDishes wDishes, HttpServletRequest request, HttpServletResponse response, Model model) {
Page<WDishes> page = wDishesService.findPage(new Page<WDishes>(request, response), wDishes);
model.addAttribute("page", page);
model.addAttribute("wDishes", new WDishes());
return "modules/dis/wDishesList";
}
