【springmvc+mybatis项目实战】杰信商贸-5.生产厂家DAO+SERVICE+CONTROLLER+JSP+配置文件

上一篇我们创建了工程和一个Factory的po对象(javaBean)，我们也写好了Mapper的映射文件，接下来我们来完成生产厂家的DAO与SERVICE，以及CONTROLLER，还有做显示的JSP页面，以及框架的配置文件。

首先回顾一下我们的系统架构:


我们的BaseDao与BaseDaoImpl:

package cn.hpu.jk.dao;import java.io.Serializable;import java.util.List;import java.util.Map;import cn.hpu.jk.pagination.Page;//泛型类，基础的DAO接口public interface BaseDao<T> {public List<T> findPage(Page page);//分页查询public List<T> find(Map paraMap);//带条件查询，条件可以为null，既没有条件；返回list对象集合public T get(Serializable id);//只查询一个，常用于修改public void insert(T entity);//插入，用实体作为参数public void update(T entity);//修改，用实体作为参数public void deleteById(Serializable id);//按id删除，删除一条；支持整数型和字符串类型IDpublic void delete(Serializable[] ids);//批量删除；支持整数型和字符串类型ID}

BaseDaoImpl：

package cn.hpu.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.hpu.jk.dao.BaseDao;import cn.hpu.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 List<T> findPage(Page page){List<T> oList = this.getSqlSession().selectList(ns + ".findPage", page);return oList;}public List<T> find(Map map) {List<T> oList = this.getSqlSession().selectList(ns + ".find", map);return oList;}public T get(Serializable id) {return this.getSqlSession().selectOne(ns + ".get", id);}public void insert(T entity) {this.getSqlSession().insert(ns + ".insert", entity);}public void update(T entity) {this.getSqlSession().update(ns + ".update", entity);}public void deleteById(Serializable id) {this.getSqlSession().delete(ns + ".deleteById", id);}public void delete(Serializable[] ids) {this.getSqlSession().delete(ns + ".delete", ids);}}

我们现在来创建自己的Dao层
FactoryDao:

package cn.hpu.jk.dao;import cn.hpu.jk.domain.Factory;public interface FactoryDao extends BaseDao<Factory>{//我们这里可以直接使用继承的BaseDao的增删改查方法//创建一系列其它Dao的原因是因为其它Dao有可能需要拓展}

FactoryDaoImpl:

package cn.hpu.jk.dao.impl;import org.springframework.stereotype.Repository;import cn.hpu.jk.dao.FactoryDao;import cn.hpu.jk.domain.Factory;@Repository //为了包扫描的时候这个Dao被扫描到public class FactoryDaoImpl extends BaseDaoImpl<Factory> implements FactoryDao{public FactoryDaoImpl(){//设置命名空间super.setNs("cn.hpu.jk.mapper.FactoryMapper");}}

接下来写service层
FactoryService:

package cn.hpu.jk.service;import java.io.Serializable;import java.util.List;import java.util.Map;import org.apache.poi.ss.formula.functions.T;import cn.hpu.jk.domain.Factory;import cn.hpu.jk.pagination.Page;public interface FactoryService {public List<Factory> findPage(Page page);//分页查询public List<Factory> find(Map paraMap);//带条件查询，条件可以为null，既没有条件；返回list对象集合public Factory get(Serializable id);//只查询一个，常用于修改public void insert(Factory factory);//插入，用实体作为参数public void update(Factory factory);//修改，用实体作为参数public void deleteById(Serializable id);//按id删除，删除一条；支持整数型和字符串类型IDpublic void delete(Serializable[] ids);//批量删除；支持整数型和字符串类型ID}

FactoryServiceImpl(我们先只实现查询)

package cn.hpu.jk.service.impl;import java.io.Serializable;import java.util.List;import java.util.Map;import javax.annotation.Resource;import org.apache.poi.ss.formula.functions.T;import org.springframework.stereotype.Service;import cn.hpu.jk.dao.FactoryDao;import cn.hpu.jk.domain.Factory;import cn.hpu.jk.pagination.Page;import cn.hpu.jk.service.FactoryService;@Servicepublic class FactoryServiceImpl implements FactoryService{@AutowiredFactoryDao factoryDao;@Overridepublic void delete(Serializable[] ids) {// TODO Auto-generated method stub}@Overridepublic void deleteById(Serializable id) {// TODO Auto-generated method stub}@Overridepublic List<Factory> find(Map paraMap) {return factoryDao.find(paraMap);}@Overridepublic List<Factory> findPage(Page page) {// TODO Auto-generated method stubreturn null;}@Overridepublic Factory get(Serializable id) {// TODO Auto-generated method stubreturn null;}@Overridepublic void insert(Factory factory) {// TODO Auto-generated method stub}@Overridepublic void update(Factory factory) {// TODO Auto-generated method stub}}

下面开始编写Controller层
看看我们之前引入的工具类BaseController:

package cn.hpu.jk.controller;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.Date;import org.springframework.beans.propertyeditors.CustomDateEditor;import org.springframework.web.bind.WebDataBinder;import org.springframework.web.bind.annotation.InitBinder;public abstract class BaseController {@InitBinder//此方法用于日期的转换，如果未加，当页面日期格式转换错误，将报400错误，实际是因为此方法public void initBinder(WebDataBinder binder) {DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");dateFormat.setLenient(true);binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));}}

然后我们创建FactoryController(继承BaseController是为了以后的扩充):

package cn.hpu.jk.controller.basicinfo.factory;import java.util.List;import javax.annotation.Resource;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import cn.hpu.jk.controller.BaseController;import cn.hpu.jk.domain.Factory;import cn.hpu.jk.service.FactoryService;public class FactoryController extends BaseController{@ResourceFactoryService factoryService;//列表@RequestMapping("/basicinfo/factory/list.action")public String list(Model model){List<Factory> dataList=factoryService.find(null);model.addAttribute("dataList", dataList);//将数据传递到页面return "/baseinfo/factory/jFactoryList.jsp";//转向页面}}

接下来我们实现jsp界面
我们首先先在main/webapp/WEB-INF/pages下写一个最最基础的jsp的配置页面
base.jsp

<%@ page language="java" pageEncoding="UTF-8"%><!--引入c标签库--><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%><!--配置虚拟路径(工程路径)--><c:set var="ctx" value="${pageContext.request.contextPath}"/><!--引入最基础的css与js配置文件--><link rel="stylesheet" rev="stylesheet" type="text/css" href="${ctx}/skin/default/css/default.css" media="all"/><script language="javascript" src="${ctx}/js/common.js"></script>

之后再写一个显示list列表的配置jsp文件:
baselist.jsp

<%@ page language="java" pageEncoding="UTF-8"%><!--引入base.jsp--><%@ include file="base.jsp"%><!--引入与list列表有关的样式表--> <link rel="stylesheet" rev="stylesheet" type="text/css" href="${ctx}/css/extreme/extremecomponents.css" />    <link rel="stylesheet" rev="stylesheet" type="text/css" href="${ctx}/css/extreme/extremesite.css" />

最后，,我们在main/webapp/WEB-INF/pages/factory下创建baseinfo文件夹，我们在里面写我们需要给用户显示的jsp界面(里面包含了baselist.jsp)
jFactoryList.jsp:

<%@ page language="java" pageEncoding="UTF-8"%><%@ include file="../../baselist.jsp"%><html xmlns="http://www.w3.org/1999/xhtml"><head><title>生产厂家列表</title></head><body><form name="icform" method="post"><div id="menubar"><div id="middleMenubar"><div id="innerMenubar">  <div id="navMenubar">  <ul><li id="view"><a href="#" onclick="formSubmit('toview.action','_self');this.blur();">查看</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">   生产厂家列表  </div>   </div>  </div>  <div><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" ><c:forEach items="${dataList}" var="o" varStatus="status"><tr class="odd" onmouseover="this.className='highlight'" onmouseout="this.className='odd'" ><td><input type="checkbox" name="id" value="${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>

接下来进行最后一步，我们要配置各种配置文件
我们现在src/main/resources下配置MyBatis的配置文件
sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!--  引入了spring就不需要这些了<environments default=""><environment id=""><transactionManager type=""></transactionManager><dataSource type=""></dataSource></environment></environments>--></configuration>

接下来我们创建spring的配置文件beans.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "><!-- 1.加载数据库配置的属性文件 --><context:property-placeholder location="classpath:jdbc.properties"/><!-- 2.包扫描:dao,service --><context:component-scan base-package="cn.hpu.jk.dao,cn.hpu.jk.service"/><!-- 3,dataSource数据源 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="${jdbc.driverClassName}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/><property name="maxPoolSize" value="${c3p0.pool.maxPoolSize}"/><property name="minPoolSize" value="${c3p0.pool.minPoolSize}" /><property name="initialPoolSize" value="${c3p0.pool.initialPoolSize}"/><property name="acquireIncrement" value="${c3p0.pool.acquireIncrement}"/></bean><!-- 4.SessionFactory --><bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><!-- 整合mybatis，包扫描mapper文件 --><property name="configLocation" value="classpath:sqlMapConfig.xml"></property><property name="mapperLocations" value="classpath:cn/hpu/jk/mapper/*.xml"></property></bean><!-- 5.事务管理--><bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean><!-- 事务通知 --><tx:advice id="txAdivce" transaction-manager="txManager"><tx:attributes><tx:method name="insert*" propagation="REQUIRED"/><tx:method name="update*" propagation="REQUIRED"/><tx:method name="delete*" propagation="REQUIRED"/><tx:method name="save*" propagation="REQUIRED"/><tx:method name="find*" read-only="false"/><tx:method name="get*" read-only="false"/><tx:method name="view*" read-only="false"/></tx:attributes></tx:advice><aop:config><aop:pointcut expression="execution(* cn.hpu.jk.service.*.*(..))" id="txPointcut"/><aop:advisor advice-ref="txAdivce" pointcut-ref="txPointcut"/></aop:config></beans>

其中jdbc.properties:

#jdbc.driverClassName=com.mysql.jdbc.Driver#jdbc.url=jdbc:mysql://localhost:3306/jkdb?characterEncoding=utf-8#jdbc.username=root#jdbc.password=1234jdbc.driverClassName=oracle.jdbc.driver.OracleDriverjdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:XEjdbc.username=jkdbjdbc.password=22c3p0.pool.maxPoolSize=20c3p0.pool.minPoolSize=5c3p0.pool.initialPoolSize=3c3p0.pool.acquireIncrement=2

然后我们的spring有关service的配置文件
beans-service.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "><!-- 加载service--><bean name="factoryService" class="cn.hpu.jk.service.impl.FactoryServiceImpl"/></beans>

接下来配置springmvc的配置文件springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "><!-- 1.扫描controller包 --><context:component-scan base-package="cn.hpu.jk.controller.*"/><!-- 2.内部资源视图解析器，suffix为空，方便跟参数 url?id=xxx --><bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/pages"/><property name="suffix" value=""/></bean><!-- 3.注解驱动 --><mvc:annotation-driven/><!-- 4.文件上传解析器，最大能上传10M文件（1024*1024*10）--><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="maxUploadSize" value="10485760"/></bean></beans>

最后我们来配置我们的web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>Archetype Created Web Application</display-name>    <!-- 1.加载spring框架容器 -->  <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:beans*.xml</param-value>  </context-param>  <listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <!-- 2.springmvc前端控制器 -->  <servlet>  <servlet-name>springmvc</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:springmvc-servlet.xml</param-value>  </init-param>  </servlet>  <servlet-mapping>  <servlet-name>springmvc</servlet-name>  <url-pattern>*.action</url-pattern>  </servlet-mapping>    <!-- 3.post乱码过虑器 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>  </web-app>

我们基本上把所有基本的东西都配置完毕了，接下来我们发布我们的工程进行测试。
将任务部署至tomcat，然后我们在浏览器上访问我们的工程，我们访问我们的路径，看看数据是否返回(我们事先在数据库中填写了一些从测试数据):
访问http://localhost/jx-Maven-Webapp/（我的tomcat默认端口是80）

点击登录到主界面，然后点击厂家信息

点击之后结果如图:

附工程源码:jx-Maven-Webapp.zip

以后会继续发布新功能模块的编写步骤
