factory表的删除分为两种:单行删除,以及批量删除。
过程:在jFactoryCreate.jsp页面上两个按钮,单行删除以及批量删除。
选中好序号后,进入action请求,然后进入Controller控制器(FactoryController.java),进入到FactoryController.java里面的public String deleteById(String id)方法或者public String delete(@RequestParam("id")String[] ids)方法。然后进入里面的Service层,然后进入到Dao层,然后调用Mybatis的FactoyMapper.xml里面的方法。
具体做法:
项目结构:
jFactoryList.jsp代码:
<%@ page language="java" pageEncoding="UTF-8"%> <hr> <font color="blue"><b>引入CSS、JS区域</b></font> <hr> <%@ include file="../../baselist.jsp"%> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <form name="icform" method="post"> <div id="menubar"> <div id="middleMenubar"> <div id="innerMenubar"> <div id="navMenubar"> <ul> <hr> <font color="blue"><b>按钮区域</b></font> <hr> <li id="view"><a href="#" onclick="formSubmit(‘toview.action‘,‘_self‘);this.blur();">查看</a></li> <li id="new"><a href="#" onclick="formSubmit(‘factorycreate.action‘,‘_self‘);this.blur();">新增</a></li> <li id="update"><a href="#" onclick="formSubmit(‘jfactoryupdate.action‘,‘_self‘);this.blur();">修改</a></li> <li id="delete"><a href="#" onclick="formSubmit(‘deleteById.action‘,‘_self‘);this.blur();">删除</a></li> <li id="delete"><a href="#" onclick="formSubmit(‘delete.action‘,‘_self‘);this.blur();">批量删除</a></li> </ul> </div> </div> </div> </div> <!-- 页面主体部分(列表等) --> <div class="textbox" id="centerTextbox"> <div class="textbox-header"> <div class="textbox-inner-header"> <div class="textbox-title"> <hr> <font color="blue"><b>标题</b></font> <hr> 生产厂家列表 </div> </div> </div> <div> <hr> <font color="blue"><b>列表区域</b></font> <hr> <div class="eXtremeTable" > <table id="ec_table" class="tableRegion" width="98%" > <thead> <tr> <td class="tableHeader"><input type="checkbox" name="selid" onclick="checkAll(‘id‘,this)"></td> <td class="tableHeader">序号</td> <td class="tableHeader">厂家全称</td> <td class="tableHeader">缩写</td> <td class="tableHeader">联系人</td> <td class="tableHeader">电话</td> <td class="tableHeader">手机</td> <td class="tableHeader">传真</td> <td class="tableHeader">验货员</td> </tr> </thead> <tbody class="tableBody" > <!--var="o"的意思是给datalist取个别名,之后用起来就简单了--> <c:forEach items="${datalist}" var="o" varStatus="status"> <tr class="odd" onmouseover="this.className=‘highlight‘" onmouseout="this.className=‘odd‘" > <!-- 做了一个选择框 --> <td><input type="checkbox" name="id" value="${o.id}"/></td> <td>${status.index+1}</td> <td><a href="toview.action?id=${o.id}">${o.fullName}</a></td> <td>${o.factoryName}</td> <td>${o.contacts}</td> <td>${o.phone }</td> <td>${o.mobile }</td> <td>${o.fax }</td> <td>${o.inspector }</td> </tr> </c:forEach> </tbody> </table> </div> </div> </form> </body> </html>
点击删除按钮,执行formSubmit(‘jfactoryupdate.action‘,‘_self‘)请求。来到FactoryContrall.java。
FactoryContrall.java代码如下:
package cn.itcast.jk.controller.basicinfo.factory; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import cn.itcast.jk.controller.BaseController; import cn.itcast.jk.domain.Factory; import cn.itcast.jk.service.FactoryService; @Controller public class FactoryController extends BaseController { @Resource FactoryService factoryService; //列表 @RequestMapping("/basicinfo/factory/list.action") public String list(Model model) { List<Factory> datalist=factoryService.find(null); model.addAttribute("datalist", datalist);//将我的数据传递到页面; return "/basicinfo/factory/jFactoryList.jsp"; } //删除一个 @RequestMapping("/basicinfo/factory/deleteById.action") public String deleteById(String id) { factoryService.deleteById(id); return "redirect:/basicinfo/factory/list.action"; } //删除多个 @RequestMapping("/basicinfo/factory/delete.action") //@RequestParam("id")String[] ids 表示在页面上叫做id,但是我封装的时候封装成ids //因为声明的是数组所以会自动的拆分 这里不同的话参考Springmvc专辑的文章23各种参数绑定方式 public String delete(@RequestParam("id")String[] ids) { factoryService.delete(ids); return "redirect:/basicinfo/factory/list.action"; } }
然后执行里面的factoryService的方法。
FactoryServiceImpl的代码如下:
package cn.itcast.jk.service.impl; import java.io.Serializable; import java.util.List; import java.util.Map; import java.util.UUID; import javax.annotation.Resource; import org.springframework.stereotype.Service; import cn.itcast.jk.dao.FactoryDao; import cn.itcast.jk.domain.Factory; import cn.itcast.jk.pagination.Page; import cn.itcast.jk.service.FactoryService; @Service public class FactoryServiceImpl implements FactoryService{ @Resource FactoryDao factoryDao; @Override public List<Factory> findPage(Page page) { return null; } @Override public List<Factory> find(Map paraMap) { return factoryDao.find(paraMap); } @Override public Factory get(Serializable id) { return factoryDao.get(id); } @Override public void insert(Factory factory) { factory.setId(UUID.randomUUID().toString()); factoryDao.insert(factory); } @Override public void update(Factory factory) { factoryDao.update(factory); } //删除一条记录 @Override public void deleteById(Serializable id) { factoryDao.deleteById(id); } //删除多条记录 @Override public void delete(Serializable[] ids) { factoryDao.delete(ids); } }
然后执行factoryDao里面的方法。
而通过spring,其实factoryDao就是FactoryDaoImpl的实例。
我们看一下FactoryDaoImpl的代码:
package cn.itcast.jk.dao.impl; import org.springframework.stereotype.Repository; import cn.itcast.jk.dao.FactoryDao; import cn.itcast.jk.domain.Factory; /* * @Repository这注册了才能在包扫面的时候把这个实例注册进bean容器。 * */ @Repository public class FactoryDaoImpl extends BaseDaoImpl<Factory> implements FactoryDao { /** * */ public FactoryDaoImpl() { //设置命名空间 super.setNs("cn.itcast.jk.mapper"); } }
我们再来看BaseDaoImpl的方法:
package cn.itcast.jk.dao.impl; import java.io.Serializable; import java.util.List; import java.util.Map; import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.support.SqlSessionDaoSupport; import org.springframework.beans.factory.annotation.Autowired; import cn.itcast.jk.dao.BaseDao; import cn.itcast.jk.pagination.Page; public abstract class BaseDaoImpl<T> extends SqlSessionDaoSupport implements BaseDao<T>{ @Autowired //mybatis-spring 1.0无需此方法;mybatis-spring1.2必须注入。 public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){ super.setSqlSessionFactory(sqlSessionFactory); } private String ns; //命名空间 public String getNs() { return ns; } public void setNs(String ns) { this.ns = ns; } public void deleteById(Serializable id) { this.getSqlSession().delete(ns + ".deleteById", id); } public void delete(Serializable[] ids) { this.getSqlSession().delete(ns + ".delete", ids); } }
最后来看Mybatis的配置文件FactoryMapper.xml的代码:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="cn.itcast.jk.mapper"> <!-- factory_c表的映射 --> <resultMap type="cn.itcast.jk.domain.Factory" id="factoryRM" > <id property="id" column="FACTORY_ID"/> <result property="fullName" column="FULL_NAME"/> <result property="factoryName" column="FACTORY_NAME"/> <result property="contacts" column="CONTACTS"/> <result property="phone" column="PHONE"/> <result property="mobile" column="MOBILE"/> <result property="fax" column="FAX"/> <result property="cnote" column="CNOTE"/> <result property="inspector" column="INSPECTOR"/> <result property="orderNo" column="ORDER_NO"/> <result property="createBy" column="CREATE_BY"/> <result property="createDept" column="CREATE_DEPT"/> <result property="createTime" column="CREATE_TIME"/> </resultMap> <select id="find" parameterType="map" resultMap="factoryRM" > select * from factory_c where 1=1 </select> <!-- 当数据库是Oracle时,如果插入的数据是空时,必须是要指定默认的参数。所以这里的设置要这么写:jdbcType=VARCHAR。 --> <insert id="insert" parameterType="cn.itcast.jk.domain.Factory"> insert into factory_c(FACTORY_ID,FULL_NAME,FACTORY_NAME,CONTACTS,PHONE,MOBILE,FAX,CNOTE,INSPECTOR,ORDER_NO,CREATE_BY,CREATE_DEPT,CREATE_TIME) values( #{id,jdbcType=VARCHAR}, #{fullName,jdbcType=VARCHAR}, #{factoryName,jdbcType=VARCHAR}, #{contacts,jdbcType=VARCHAR}, #{phone,jdbcType=VARCHAR}, #{mobile,jdbcType=VARCHAR}, #{fax,jdbcType=VARCHAR}, #{cnote,jdbcType=VARCHAR}, #{inspector,jdbcType=VARCHAR}, #{orderNo,jdbcType=INTEGER}, #{createBy,jdbcType=VARCHAR}, #{createDept,jdbcType=VARCHAR}, #{createTime,jdbcType=TIMESTAMP} ) </insert> <!-- 修改 动态的sql语句--> <update id="update" parameterType="cn.itcast.jk.domain.Factory"> update factory_c <set> <!-- 如果 fullName不为空,就修改。--> <if test="fullName!=null">FULL_NAME=#{fullName,jdbcType=VARCHAR},</if> <if test="factoryName!=null">FACTORY_NAME=#{factoryName,jdbcType=VARCHAR},</if> <if test="contacts!=null">CONTACTS=#{contacts,jdbcType=VARCHAR},</if> <if test="phone!=null">PHONE=#{phone,jdbcType=VARCHAR},</if> <if test="mobile!=null">MOBILE=#{mobile,jdbcType=VARCHAR},</if> <if test="fax!=null">FAX=#{fax,jdbcType=VARCHAR},</if> <if test="cnote!=null">CNOTE=#{cnote,jdbcType=VARCHAR},</if> <if test="inspector!=null">INSPECTOR=#{inspector,jdbcType=VARCHAR},</if> <if test="orderNo!=null">ORDER_NO=#{orderNo,jdbcType=INTEGER},</if> <if test="createBy!=null">CREATE_BY=#{createBy,jdbcType=VARCHAR},</if> <if test="createDept!=null">CREATE_DEPT=#{createDept,jdbcType=VARCHAR},</if> <if test="createTime!=null">CREATE_TIME=#{createTime,jdbcType=TIMESTAMP},</if> </set> where FACTORY_ID=#{id} </update> <!-- 查询一个数据 --> <select id="get" parameterType="string" resultMap="factoryRM"> <!-- 注意我这里写了一个factory_id=#{pid},我这么写主要是为了说明这里要传入的值并不是 factory这个类里面的属性,可以是随意的,只要是String就好。 --> select * from factory_c where factory_id=#{pid} </select> <!-- 删除一条的 --> <delete id="deleteById" parameterType="string"> delete from factory_c where FACTORY_ID=#{pid} </delete> <!-- 删除多条的记录 --> <delete id="delete" parameterType="string"> delete from factory_c where FACTORY_ID in <foreach collection="array" item="id" open="(" close=")" separator=","> #{id} </foreach> </delete> </mapper>
到这里就结束了。
执行OK.
