上次我们实现了生产厂家的修改，这次我们再实现生产厂家的删除
删除我们分两种情况，一种是删除一条，一种是删除多条，我们都实现
我们首先在FactoryMapper.xml中设置删除配置语句：
<!-- 删除一条 -->
<delete id="deleteById" parameterType="string">
delete from factory_c
where FACTORY_ID=#{id}
</delete>
<!-- 删除多条(一维字符串数组的形式) -->
<delete id="delete" parameterType="string">
delete from factory_c
where FACTORY_ID in
<foreach collection="array" item="id" open="(" close=")" separator=",">
#{id}
</foreach>
</delete>
然后我们来写dao层
由于我们的FactoryDaoImpl继承了BaseDaoimpl，所以里面有如下两个方法：
public void deleteById(Serializable id) {
this.getSqlSession().delete(ns + ".deleteById", id);
}
public void delete(Serializable[] ids) {
this.getSqlSession().delete(ns + ".delete", ids);
} 我们就无需在FactoryDaoImpl里面写删除方法了
我们来看Service层
在FactoryService中加入如下两个方法的实现
@Override
public void delete(Serializable[] ids) {
factoryDao.delete(ids);
}
@Override
public void deleteById(Serializable id) {
factoryDao.deleteById(id);
}
接下来看我们的Controller层
在FactoryController中编写有关delete的方法
//删除一个
@RequestMapping("/basicinfo/factory/deleteById.action")
public String deleteById(String id){
factoryService.deleteById(id);
return "redirect:/basicinfo/factory/list.action";
}
//删除多条
@RequestMapping("/basicinfo/factory/delete.action")
public String delete(@RequestParam("id") String[] ids){
factoryService.delete(ids);
return "redirect:/basicinfo/factory/list.action";
}
我们还剩下删除的前台界面入口
我们在WEB-INF/pages/baseinfo/factory/jFactoryList.jsp中添加删除一个和删除多个的按钮:
<li id="delete"><a href="#" οnclick="formSubmit('deleteById.action','_self');this.blur();">删除</a></li>
<li id="delete"><a href="#" οnclick="formSubmit('delete.action','_self');this.blur();">删除N</a></li> 接下来我们重启服务器进行测试
首先点击“删除”来删除一条信息
删除成功！
然后点击“删除N”，然后选择多个进行删除
删除成功！
接下来我们来编写查看某个生产厂家的详细信息的代码
首先我们的FactoryMapper.xml之前我们已经写好了一个查询一个厂家的配置语句：
<!-- 查询一个 -->
<select id="get" parameterType="string" resultMap="factoryRM">
select * from factory_c
where factory_id=#{id}
</select>
然后我们的dao层由于继承了BaseDaoImpl，所以自然包含了下面这个方法
public T get(Serializable id) {
return this.getSqlSession().selectOne(ns + ".get", id);
}
Service层我们之前也写过相关方法
@Override
public Factory get(Serializable id) {
return factoryDao.get(id);
}
接下来我们在Controller层编写有关查看的方法
//查看
@RequestMapping("/basicinfo/factory/toview.action")
public String toview(String id,Model model){
Factory obj=factoryService.get(id);
model.addAttribute("obj",obj);
return "/baseinfo/factory/jFactoryView.jsp";
}
最后,我们编写一下jFactoryView.jsp查看界面
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ include file="../../base.jsp"%>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>查看厂家信息</title>
</head>
<body>
<form method="post">
<div id="menubar">
<div id="middleMenubar">
<div id="innerMenubar">
<div id="navMenubar">
<ul>
<li id="back"><a href="list.action">返回</a></li>
</ul>
</div>
</div>
</div>
</div>
<div class="textbox" id="centerTextbox">
<div class="textbox-header">
<div class="textbox-inner-header">
<div class="textbox-title">
查看生产厂家信息
</div>
</div>
</div>
<div>
<div>
<table class="commonTable" cellspacing="1">
<tr>
<td class="columnTitle_mustbe">厂家名称：</td>
<td class="tableContent">${obj.fullName }</td>
<td class="columnTitle_mustbe">简称：</td>
<td class="tableContent">${obj.factoryName }</td>
</tr>
<tr>
<td class="columnTitle_mustbe">联系人：</td>
<td class="tableContent">${obj.contacts }</td>
<td class="columnTitle_mustbe">电话：</td>
<td class="tableContent">${obj.phone }</td>
</tr>
<tr>
<td class="columnTitle_mustbe">手机：</td>
<td class="tableContent">${obj.mobile }</td>
<td class="columnTitle_mustbe">传真：</td>
<td class="tableContent">${obj.fax }</td>
</tr>
<tr>
<td class="columnTitle_mustbe">检验员：</td>
<td class="tableContent">${obj.inspector }</td>
<td class="columnTitle_mustbe">排序号：</td>
<td class="tableContent">${obj.orderNo }</td>
</tr>
<tr>
<td class="columnTitle_mustbe">备注：</td>
<td class="tableContent">${obj.cnote }</td>
</tr>
</table>
</div>
</div>
</form>
</body>
</html>
我们之前在列表jFactoryList.jsp界面中有“查看”按钮：
<li id="view"><a href="#" οnclick="formSubmit('toview.action','_self');this.blur();">查看</a></li> 重启服务器测试
点击查询
查询结果
