SSH系列：（32）年度投诉数统计
1、JSP页面
annualStatisticChartUI.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
Calendar cal = Calendar.getInstance();
int curYear = cal.get(Calendar.YEAR);//当前年份
request.setAttribute("curYear", curYear);
List yearList = new ArrayList();
//设置页面上的年份下接框，近5年的年份
for(int i=0;i<5;i++){
yearList.add(i, curYear--);
}
request.setAttribute("yearList", yearList);
%>

</body>
</html>知识点（1）：在JSP页面中取前4年的数据
使用了Calendar，并保存在了request中
Calendar cal = Calendar.getInstance();
int curYear = cal.get(Calendar.YEAR);//当前年份
request.setAttribute("curYear", curYear);
List yearList = new ArrayList();
//设置页面上的年份下接框，近5年的年份
for(int i=0;i<5;i++){
yearList.add(i, curYear--);
}
request.setAttribute("yearList", yearList);2、后台
2.1、Action层
ComplainAction.java
package com.rk.tax.action;
import java.net.URLDecoder;
import java.sql.Timestamp;
import java.util.Calendar;
import java.util.Date;
import java.util.List;
import java.util.Map;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.time.DateUtils;
import org.apache.struts2.ServletActionContext;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.opensymphony.xwork2.ActionContext;
import com.rk.core.action.BaseAction;
import com.rk.core.entity.JsonResult;
import com.rk.core.utils.QueryHelper;
import com.rk.tax.entity.Complain;
import com.rk.tax.entity.Complainreply;
import com.rk.tax.service.ComplainService;
@Controller("complainAction")
@Scope("prototype")
public class ComplainAction extends BaseAction {
/*****1、业务数据*****/
private Complain complain;
private String startTime;
private String endTime;
private String state;
private Complainreply reply;
private JsonResult result;
/*****2、业务实现类*****/
@Resource
private ComplainService complainService;
/*****3、响应页面操作*****/
//列表
public String listUI(){
//加载状态集合
ActionContext.getContext().getContextMap().put("complainStateMap", Complain.COMPLAIN_STATE_MAP);
try {
QueryHelper queryHelper = new QueryHelper(Complain.class, "c");
if(StringUtils.isNotBlank(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+":00", "yyyy-MM-dd HH:mm:ss"));
}
if(StringUtils.isNotBlank(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+":00", "yyyy-MM-dd HH:mm:ss"));
}
if(StringUtils.isNotBlank(searchContent)){
searchContent = URLDecoder.decode(searchContent, "utf-8");
queryHelper.addCondition("c.compTitle like ?", "%" + searchContent + "%");
}
if(StringUtils.isNotBlank(state)){
queryHelper.addCondition("c.state=?", state);
}
//按照状态升序排序
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, pageNo, pageSize);
} catch (Exception e) {
e.printStackTrace();
}
return "listUI";
}
//跳转到受理页面
public String dealUI(){
//加载状态集合
ActionContext.getContext().getContextMap().put("complainStateMap", Complain.COMPLAIN_STATE_MAP);
if(complain != null && StringUtils.isNotBlank(complain.getCompId())){
complain = complainService.findById(complain.getCompId());
}
return "dealUI";
}
public String deal(){
if(complain != null && StringUtils.isNotBlank(complain.getCompId())){
Complain temp = complainService.findById(complain.getCompId());
//1、更新投诉的状态为 已受理
if(!Complain.COMPLAIN_STATE_DONE.equals(temp.getState())){
temp.setState(Complain.COMPLAIN_STATE_DONE);
}
//2、保存回复信息
if(reply != null){
reply.setComplain(temp);
/**
* 在后台设置时间，有两点好处：
* （1）在前台JSP页面，不需要再提供相应的表单域
* （2）有两个时间：JSP前台页面生成的时间、服务器保存数据的时间，后者更准确一些
*/
reply.setReplyTime(new Timestamp(new Date().getTime()));
temp.getComplainreplies().add(reply);
}
complainService.update(temp);
}
return "list";
}
//跳转到统计页面
public String annualStatisticChartUI(){
return "annualStatisticChartUI";
}
//根据年度获取该年度下的统计数
public String getAnnualStatisticData(){
//1、获取年份
HttpServletRequest request = ServletActionContext.getRequest();
int year = 0;
if(request.getParameter("year") != null){
year = Integer.valueOf(request.getParameter("year"));
}
else{
//默认 当前年份
year = Calendar.getInstance().get(Calendar.YEAR);
}
//2、获取统计年度的每个月的投诉数
result = new JsonResult();
result.setStatus(JsonResult.OK);
@SuppressWarnings("rawtypes")
List<Map> list = complainService.getAnnualStatisticDataByYear(year);
result.setData(list);
return "annualStatisticData";
}
// Properties
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;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public Complainreply getReply() {
return reply;
}
public void setReply(Complainreply reply) {
this.reply = reply;
}
public JsonResult getResult() {
return result;
}
public void setResult(JsonResult result) {
this.result = result;
}
}其中关注的重点是getAnnualStatisticData方法，它返回需要的JSON数据。
在struts.xml中映射如下：
<!-- ComplainAction -->
<action name="complain_*" class="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="searchContent">${searchContent}</param>
<param name="pageNo">${pageNo}</param>
<param name="state">${state}</param>
<param name="encode">true</param>
</result>
<result name="annualStatisticData" type="json">
<param name="root">result</param>
</result>
</action>2.2、Service层

//是否当前年份
boolean isCurrentYear = (cal.get(Calendar.YEAR) == year);
int curMonth = cal.get(Calendar.MONTH)+1;//当前月份
//2、格式化统计结果
int tempMonth = 0;

ComplainDao.java
package com.rk.tax.dao;
import java.util.List;
import com.rk.core.dao.BaseDao;
import com.rk.tax.entity.Complain;
public interface ComplainDao extends BaseDao<Complain> {

StringBuilder sb = new StringBuilder();
