freemarker模板引擎
一、创建模板
来客姓名: ${informationMap.VISITOR_NAME}
到访时间: ${informationMap.ARRIVEVISIT_TIME}
同行人数: ${informationMap.PEER_NUMBER}
来客职务: ${informationMap.DUTY_NAME}
行政级别: ${informationMap.ADMINISTRATIVE_LEVEL_LABEL}
联系人: ${informationMap.CONTACTS}
联系电话: ${informationMap.CONTACTS_TEL}
任务内容
任务内容: ${taskMap.TASK_CONTENT_LABEL}
到站方式: ${taskMap.ARRIVE_STATION_LABEL}
交通工具: ${taskMap.ARRIVE_INFORMATION1}，${taskMap.ARRIVE_INFORMATION2}，${taskMap.ARRIVE_INFORMATION3}
出发地: ${taskMap.ARRIVE_PLACE}
离站方式: ${taskMap.LEAVE_STATION_LABEL}
交通工具: ${taskMap.LEAVE_INFORMATION1}，${taskMap.LEAVE_INFORMATION2}，${taskMap.LEAVE_INFORMATION3}
目的地: ${taskMap.LEAVE_PLACE}
上传下达
执行部门/人: ${signMap.IMPLEMENT_ORG_USER}
执行领导: ${signMap.IMPLEMENT_LEADER}
周知部门/人: ${signMap.KNOWN_ORG_USER}
贵宾室: ${signMap.POSTDUTY_PLACE}
接待人员: ${signMap.RECEPTION_USER}
二、java
在执行保存功能时，把模板保存到数据库
//更新模板
VisitorImportant visitorImportant = baseInfoService.getObjectById(VisitorImportant.class, id);
//进行保存模板操作
createVisitorImportantDetail(visitorImportant, "visitorImportantPC.ftl"); /**
*
* @Description 保存重要来客可查看信息的模板
* @param visitorImportant
* @param templatesName
* @return ReturnDatas
* @throws Exception
*
*/
@Override
@Transactional(propagation = Propagation.REQUIRED)
public VisitorImportantDetail createVisitorImportantDetail(VisitorImportant visitorImportant,String templatesName) throws Exception {
ReturnDatas returnDatas = new ReturnDatas();
String id_visitor_important = visitorImportant.getId();
VisitorImportantDetail visitorImportantDetail = visitorImportantDetailService.getVisitorImportantDetailByInstId(id_visitor_important);
String informationSql = "select " +
"t.id as id , " + //主键id
"t.visitor_name as visitor_name," + //来客姓名
"t.arrivevisit_time as arrivevisit_time, " + //到访时间
"t.peer_number as peer_number, " + //同行人数
"t.duty_name as duty_name, " + //来客职务
"t.administrative_level_label as administrative_level_label, " + //行政级别
"t.contacts as contacts ,"+ //联系人
"t.contacts_tel as contacts_tel " + //联系电话
" from v_visitor_important t " +
" where t.id = '"+id_visitor_important+"'";
List> informationMap = baseInfoService.listMapQueryBySql(informationSql);
LinkedHashMap linkMap = new LinkedHashMap();
VisitorImportantDetailPo visitorImportantDetailPo = new VisitorImportantDetailPo();
if(informationMap!=null && informationMap.size()>0) {
Map map = informationMap.get(0);
//替换jsonArray中的值
for(String key : map.keySet()) {
linkMap.put(key, map.get(key));
}
visitorImportantDetailPo.setInformationMap(linkMap);
}
String hql = "select u from VisitorImportant u where id = '"+id_visitor_important+"'";
VisitorImportant v = (VisitorImportant) baseInfoService.getObjectByHql(hql);
String arriveType = v.getDict_arrive_station();
String arrive_information1 = "t.arrive_station_transportation";
String arrive_information2 = "t.arrive_station_contact";
String arrive_information3 = "t.arrive_station_othertime";
String arrive_place = arrive_information2;
if("0".equals(arriveType)) {
arrive_information1 = "t.arrive_station_train";
arrive_information2 = "t.arrive_station_seat";
arrive_information3 = "t.arrive_station_place";
arrive_place = arrive_information3;
}else if("1".equals(arriveType)) {

arrive_place = arrive_information2;
}
String leaveType = v.getDict_leave_station();
String leave_information1 = "t.leave_station_transportation";
String leave_information2 = "t.leave_station_contact";
String leave_information3 = "t.leave_station_othertime";
String leave_place = leave_information2;
if("0".equals(leaveType)) {
leave_information1 = "t.leave_station_train";
leave_information2 = "t.leave_station_seat";
leave_information3 = "t.leave_station_place";
leave_place = leave_information3;
}else if("1".equals(leaveType)) {
leave_information1 = "t.leave_station_car";
leave_information2 = "t.leave_station_park";
leave_information3 = "t.leave_station_cartime";
leave_place = leave_information2;
}
String taskSql = "select " +
"t.id as id, " + //主键id
"t.task_content_label as task_content_label," + //任务内容
"t.arrive_station_label as arrive_station_label, " + //到站方式

" from v_visitor_important t " +
" where t.id = '"+id_visitor_important+"'";
List> taskMap = baseInfoService.listMapQueryBySql(taskSql);
LinkedHashMap taskLinkMap = new LinkedHashMap();
if(taskMap!=null && taskMap.size()>0) {
Map map = taskMap.get(0);
//替换jsonArray中的值
for(String key : map.keySet()) {
taskLinkMap.put(key, map.get(key));
}
visitorImportantDetailPo.setTaskMap(taskLinkMap);
}
String signSql = "select " +
"t.id as id , " + //主键id
"t.implement_org_user as implement_org_user," + //执行部门/人
"t.implement_leader as implement_leader, " + //执行领导
"t.known_org_user as known_org_user, " + //周知部门/人
"t.known_leader as known_leader, " + //周知领导
"t.postduty_place as postduty_place, " + //贵宾室
"t.reception_user as reception_user " + //接待人员
" from v_visitor_important t " +
" where t.id = '"+id_visitor_important+"'";
List> signMap = baseInfoService.listMapQueryBySql(signSql);
LinkedHashMap signLinkMap = new LinkedHashMap();
if(signMap!=null && signMap.size()>0) {
Map map = signMap.get(0);
//替换jsonArray中的值
for(String key : map.keySet()) {
signLinkMap.put(key, map.get(key));
}
visitorImportantDetailPo.setSignMap(signLinkMap);
}
//字符流
StringWriter stringWriterPC = new StringWriter();
//StringWriter stringWriterAPP = new StringWriter();
try {
//Map map = JSON.parseObject(detailStr);
//创建配置实例
Configuration configuration = new Configuration(Configuration.VERSION_2_3_23);
//设置编码
configuration.setDefaultEncoding("UTF-8");
//空值
configuration.setClassicCompatible(true);
//ftl模板文件
configuration.setClassForTemplateLoading(VisitorImportantServiceImpl.class, "/templates/");
String tempPc = "visitorImportantPC.ftl";
//String tempApp = "taskApp.ftl";
//获取PC模板
Template templatePC = configuration.getTemplate(tempPc);
//替换
templatePC.process(visitorImportantDetailPo, stringWriterPC);
} catch (Exception e) {
LogUtil.error(e.getMessage(),e);
returnDatas.setStatus(ReturnDatas.ERROR);
returnDatas.setMessage("freeMarker替换模板出错");
}
System.out.println(stringWriterPC.toString());
//转化为JSON
String detailStr = JSON.toJSONString(visitorImportantDetailPo);
String contentPC = stringWriterPC.toString();
String contentAPP = "";
//封装emergencyInsyDetail对象
visitorImportantDetail.setId_visitor_important(id_visitor_important);
visitorImportantDetail.setInst_content(detailStr);
visitorImportantDetail.setInst_content_pc(contentPC);
visitorImportantDetail.setInst_content_app(contentAPP);
//保存静态Html对象
visitorImportantDetail = visitorImportantDetailService.saveVisitorImportantDetail(visitorImportantDetail); 三、VisitorImportantDetailPo实体类public class VisitorImportantDetailPo{
private LinkedHashMap informationMap;
private LinkedHashMap taskMap;
private LinkedHashMap signMap;
public LinkedHashMap getInformationMap() {
return informationMap;
}
public void setInformationMap(LinkedHashMap informationMap) {
this.informationMap = informationMap;
}
public LinkedHashMap getTaskMap() {
return taskMap;
}
public void setTaskMap(LinkedHashMap taskMap) {
this.taskMap = taskMap;
}
public LinkedHashMap getSignMap() {
return signMap;
}
public void setSignMap(LinkedHashMap signMap) {
this.signMap = signMap;
}
} 四、数据库效果如下
从数据库读取到数据后替换页面即可
