【SSH项目实战】国税协同平台-29.投诉受理查询

我们之前已经成功创建了数据库，现在我们要对建好的表使用“逆向工程”来创建相应的实体类以及映射文件。

我们的“逆向工程”在第五阶段“5.逆向工程.txt”章中已经详细阐述过，这里的过程就不再赘述。

首先我们还是调出我们的DB Browser，然后找到我们的数据库连接，找到要逆向工程的两张表，点击右键，选择“hibernate Reverse Engineering...”之后就会弹出以下对话框:



做出相应的操作之后，我们的实体类以及映射文件就自动生成完毕了:



其中我们实体集以及映射文件的详细内容如下:

Complain.java:

public class Complain implements java.io.Serializable {

// Fields

private String compId;
private String compCompany;
private String compName;
private String compMobile;
private Boolean isNm;
private Timestamp compTime;
private String compTitle;
private String toCompName;
private String toCompDept;
private String compContent;
private String state;
private Set complainReplies = new HashSet(0);

// Constructors

/** default constructor */
public Complain() {
}

/** minimal constructor */
public Complain(String compTitle) {
this.compTitle = compTitle;
}

/** full constructor */
public Complain(String compCompany, String compName, String compMobile, Boolean isNm, Timestamp compTime, String compTitle, String toCompName, String toCompDept, String compContent, String state,
Set complainReplies) {
this.compCompany = compCompany;
this.compName = compName;
this.compMobile = compMobile;
this.isNm = isNm;
this.compTime = compTime;
this.compTitle = compTitle;
this.toCompName = toCompName;
this.toCompDept = toCompDept;
this.compContent = compContent;
this.state = state;
this.complainReplies = complainReplies;
}
// 下面是get和set方法，这里不再赘述
}

Complain.hbm.xml:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

</key>
<one-to-many class="cn.edu.hpu.tax.complain.entity.ComplainReply" />
</set>
</class>
</hibernate-mapping>

ComplainReply.java:

package cn.edu.hpu.tax.complain.entity;

import java.sql.Timestamp;

/**
* ComplainReply entity. @author MyEclipse Persistence Tools
*/

public class ComplainReply implements java.io.Serializable {

// Fields

private String replyId;
private Complain complain;
private String replyer;
private String replyDept;
private Timestamp replyTime;
private String replyContent;

// Constructors

/** default constructor */
public ComplainReply() {
}

/** minimal constructor */
public ComplainReply(Complain complain) {
this.complain = complain;
}

/** full constructor */
public ComplainReply(Complain complain, String replyer, String replyDept, Timestamp replyTime, String replyContent) {
this.complain = complain;
this.replyer = replyer;
this.replyDept = replyDept;
this.replyTime = replyTime;
this.replyContent = replyContent;
}
// 下面是get和set方法，这里不再赘述
}

ComplainReply.hbm.xml:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--

<hibernate-mapping>

<property name="replyContent" type="java.lang.String">

</property>
</class>
</hibernate-mapping>

可以看到我们正确生成了实体集以及映射文件。

然后我们的Complain有一些状态，我们来为它添加这些状态(就在Complain.java中):

//状态
public static String COMPLAIN_STATE_UNDONE = "0";//待受理
public static String COMPLAIN_STATE_DONE = "1";//已受理
public static String COMPLAIN_STATE_INVALID = "2";//已失效
public static Map<String, String> COMPLAIN_STATE_MAP;
static {
COMPLAIN_STATE_MAP = new HashMap<String, String>();
COMPLAIN_STATE_MAP.put(COMPLAIN_STATE_UNDONE, "待受理");
COMPLAIN_STATE_MAP.put(COMPLAIN_STATE_DONE, "已受理");
COMPLAIN_STATE_MAP.put(COMPLAIN_STATE_INVALID, "已失效");
}

实体集写完，之后是Dao层:

package cn.edu.hpu.tax.complain.dao;

import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.core.dao.BaseDao;

public interface ComplainDao extends BaseDao<Complain> {

}

package cn.edu.hpu.tax.complain.dao.impl;

import cn.edu.hpu.tax.complain.dao.ComplainDao;
import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.core.dao.impl.BaseDaoImpl;

public class ComplainDaoImpl extends BaseDaoImpl<Complain> implements ComplainDao{

}

然后是Service层:

package cn.edu.hpu.tax.complain.service;

import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.core.service.BaseService;

public interface ComplainService extends BaseService<Complain> {

}

package cn.edu.hpu.tax.complain.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import cn.edu.hpu.tax.complain.dao.ComplainDao;
import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.complain.service.ComplainService;
import cn.edu.hpu.tax.core.service.impl.BaseServiceImpl;

@Service("complainService")
public class ComplainServiceImpl extends BaseServiceImpl<Complain> implements
ComplainService {

private ComplainDao complainDao;

@Resource
public void setComplainDao(ComplainDao complainDao) {
super.setBaseDao(complainDao);
this.complainDao = complainDao;
}
}

之后使我们的Action:

package cn.edu.hpu.tax.complain.action;

import javax.annotation.Resource;

import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.complain.service.ComplainService;
import cn.edu.hpu.tax.core.action.BaseAction;
import cn.edu.hpu.tax.core.util.QueryHelper;

public class ComplainAction extends BaseAction {

@Resource
private ComplainService complainService;
private Complain complain;

//列表
public String listUI(){
//加载状态集合
ActionContext.getContext().getContextMap().put("complainStateMap", Complain.COMPLAIN_STATE_MAP);
QueryHelper queryHelper=new QueryHelper(Complain.class,"c");
pageResult=complainService.getPageResult(queryHelper, getPageNo(), getPageSize());
return "listUI";
}

public Complain getComplain() {
return complain;
}

public void setComplain(Complain complain) {
this.complain = complain;
}
}

然后使我们的配置文件:

complain-spring.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:p="http://www.springframework.org/schema/p"
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/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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<!-- 继承了注入sessionFactory的抽象类，不用反复出入sessionFactory -->
<bean id="complainDao" class="cn.edu.hpu.tax.complain.dao.impl.ComplainDaoImpl" parent="xDao"></bean>

<!-- 扫描Service -->
<context:component-scan base-package="cn.edu.hpu.tax.complain.service.impl"></context:component-scan>
</beans>

complain-struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
<package name="complain-action" namespace="/tax" extends="base-default">
<action name="complain_*" class="cn.edu.hpu.tax.complain.action.ComplainAction" method="{1}">
<result name="{1}">/WEB-INF/jsp/tax/complain/{1}.jsp</result>
<result name="list" type="redirectAction">
<param name="actionName">complain_listUI</param>
<param name="complain.name">${strTitle}</param>
<param name="pageNo">${pageNo}</param>
<param name="encode">true</param><!-- 需要编码 -->
</result>
</action>
</package>
</struts>

然后将complain-spring.xml加入总配置文件中:

<!-- 投诉受理的struts配置文件 -->
<include file="cn/edu/hpu/tax/complain/conf/complain-struts.xml"/>

然后将我们美工做的前台页面加入到WEB-INF/jsp/tax/complain文件夹下:



首先是listUI.jsp:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<%@include file="/common/header.jsp"%>
<title>投诉受理管理</title>
<script type="text/javascript" src="${basePath }js/datepicker/WdatePicker.js"></script>
<script type="text/javascript">
var list_url = "${basePath}tax/complain_listUI.action";
//搜索
function doSearch(){
//重置页号
$("#pageNo").val(1);
document.forms[0].action = list_url;
document.forms[0].submit();
}
//受理
function doDeal(compId){
document.forms[0].action = "${basePath}tax/complain_dealUI.action?complain.compId=" + compId;
document.forms[0].submit();
}
</script>
</head>
<body class="rightBody">
<form name="form1" action="" method="post">
<div class="p_d_1">
<div class="p_d_1_1">
<div class="content_info">
<div class="c_crumbs"><div><b></b><strong>投诉受理管理</strong></div> </div>
<div class="search_art">
<li>
投诉标题：<s:textfield name="complain.compTitle" cssClass="s_text"  cssStyle="width:160px;"/>
</li>
<li>
投诉时间：<s:textfield id="startTime" name="startTime" cssClass="s_text"  cssStyle="width:160px;"
readonly="true" onfocus="WdatePicker({'skin':'whyGreen','dateFmt':'yyyy-MM-dd HH:mm'});"/>
-
<s:textfield id="endTime" name="endTime" cssClass="s_text"  cssStyle="width:160px;"
readonly="true" onfocus="WdatePicker({'skin':'whyGreen','dateFmt':'yyyy-MM-dd HH:mm'});"/>
</li>
<li>
状态：<s:select name="complain.state" list="#complainStateMap" headerKey="" headerValue="全部"/>
</li>
<li><input type="button" class="s_button" value="搜 索" onclick="doSearch()"/></li>
<li style="float:right;">
<input type="button" value="统计" class="s_button" onclick="doAnnualStatistic()"/> 
</li>

</div>

<div class="t_list" style="margin:0px; border:0px none;">
<table width="100%" border="0">
<tr class="t_tit">
<td align="center">投诉标题</td>
<td width="120" align="center">被投诉部门</td>
<td width="120" align="center">被投诉人</td>
<td width="140" align="center">投诉时间</td>
<td width="100" align="center">受理状态</td>
<td width="100" align="center">操作</td>
</tr>
<s:iterator value="pageResult.items" status="st">
<tr <s:if test="#st.odd"> bgcolor="f8f8f8" </s:if> >
<td align="center"><s:property value="compTitle"/></td>
<td align="center"><s:property value="toCompDept"/></td>
<td align="center"><s:property value="toCompName"/></td>
<td align="center"><s:date name="compTime" format="yyyy-MM-dd HH:mm"/></td>
<td align="center"><s:property value="#complainStateMap[state]"/></td>
<td align="center">
<a href="javascript:doDeal('<s:property value='compId'/>')">受理</a>
</td>
</tr>
</s:iterator>
</table>
</div>
</div>

<jsp:include page="/common/pageNavigator.jsp"/>

</div>
</div>
</form>

</body>
</html>

然后在侧边栏left.jsp中添加功能链接:

<dl class="">
<dt><a class="tssl" href="${ctx }tax/complain_listUI.action" target="mainFrame"><b></b>投诉受理管理<s lass="down"></s> </a>
</dt>
</dl>

我们添加几个测试数据(complain表):



重启服务器测试:



测试成功！我们接下来完成它的条件查询功能。我们从“标题”、“时间段”和“状态”三个条件去查询，所以我们的查询功能和以往单一查询条件不太一样，我们要做到“条件合并查询”和“防止查询条件和当前页码被覆盖”这两个重要过程。

(PS:我们的时间段是这么理解的:

投诉时间 【开始时间】 - 【结束时间】

查询开始时间之后的投诉记录

查询结束时间之前的投诉记录

)

我们下面来完善我们的Action，使其能够进行正常的查询功能(我们添加了开始时间startTime、结束时间endTime条件的查询，以及排序):

package cn.edu.hpu.tax.complain.action;

import java.net.URLDecoder;

import javax.annotation.Resource;

import org.apache.commons.lang.time.DateUtils;
import org.apache.commons.lang3.StringUtils;

import cn.edu.hpu.tax.complain.entity.Complain;
import cn.edu.hpu.tax.complain.service.ComplainService;
import cn.edu.hpu.tax.core.action.BaseAction;
import cn.edu.hpu.tax.core.util.QueryHelper;

import com.opensymphony.xwork2.ActionContext;

public class ComplainAction extends BaseAction {

@Resource
private ComplainService complainService;
private Complain complain;
private String startTime;
private String endTime;

//列表
public String listUI() throws Exception{
//加载状态集合
ActionContext.getContext().getContextMap().put("complainStateMap", Complain.COMPLAIN_STATE_MAP);
QueryHelper queryHelper=new QueryHelper(Complain.class,"c");
if(StringUtils.isNoneBlank(startTime)){//查询开始时间之后的投诉数据
startTime=URLDecoder.decode(startTime,"utf-8");
queryHelper.addCondition("c.compTime > ?",DateUtils.parseDate(startTime, new String[]{"yyyy-MM-dd HH:mm"}));

}
if(StringUtils.isNoneBlank(endTime)){//查询结束时间之前的投诉数据
endTime=URLDecoder.decode(endTime,"utf-8");
queryHelper.addCondition("c.compTime < ?",DateUtils.parseDate(endTime, new String[]{"yyyy-MM-dd HH:mm"}));

}

if(complain!=null){
if(StringUtils.isNoneBlank(complain.getState())){
queryHelper.addCondition("c.state=?", complain.getState());
}
if(StringUtils.isNoneBlank(complain.getCompTitle())){
complain.setCompTitle(URLDecoder.decode(complain.getCompTitle(),"utf-8"));
queryHelper.addCondition("c.compTitle like ?", "%"+complain.getCompTitle()+"%");
}
}

//按照状态升序排序(待受理排前，已受理和过期在后)
queryHelper.addOrderByProperty("c.state", QueryHelper.ORDER_BY_ASC);
//按照投诉时间升序排序
queryHelper.addOrderByProperty("c.compTime", QueryHelper.ORDER_BY_ASC);

pageResult=complainService.getPageResult(queryHelper, getPageNo(), getPageSize());
return "listUI";
}

public Complain getComplain() {
return complain;
}

public void setComplain(Complain complain) {
this.complain = complain;
}

public String getStartTime() {
return startTime;
}

public void setStartTime(String startTime) {
this.startTime = startTime;
}

public String getEndTime() {
return endTime;
}

public void setEndTime(String endTime) {
this.endTime = endTime;
}

}

虽然我们暂时还没有做回显，但是我们可以先测试一下我们的分段多条件查询是否成功:





我们的分段多条件查询功能编写成功。下一次我们继续进行功能的完善。
