大数据ssm项目案例总结

在本月我们学习了redis的缓存，数据导入，导出，图片的上传，MQ以及柱状图和饼状图，这里总结了开发中一些常用的功能，以及处理异常的方法，若本文对你有所收获，请一键三连，就是对我最大的支持。

redis 的缓存：

首先我们需要导入redis 的jar包：

       <!--jedis整合jar包-->
<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>3.0.1</version>
</dependency>

applicationContext.xml 需要配置：

<!-- =======================jedis配置=========================== -->
<bean id="jedisPollConfig" class="redis.clients.jedis.JedisPoolConfig"><property name="maxTotal" value="50" /><property name="maxIdle" value="20" /><property name="testOnBorrow" value="true" />
</bean>
<bean id="jedisPool" class="redis.clients.jedis.JedisPool"><constructor-arg name="poolConfig" ref="jedisPollConfig" /><constructor-arg name="host" value="localhost" /><constructor-arg name="port" value="6379" /><constructor-arg name="timeout" value="10000" /><constructor-arg name="password" value="root" />
</bean>

在Controller中注意：要加注解

@Autowired
private JedisPool  jedisPool;

在实体类中要加@GeneratedValue(generator = "JDBC")

增加的时候：

                String json = JSONObject.toJSONString(actore);//       String 类型的    jedisPool.getResource().set(actore.getId()+"",json);
//             使用Hash类型jedisPool.getResource().hset("actore",actore.getId()+"",json);

删除的时候：

jedisPool.getResource().del(id);

导入的前端代码：

<%--导入--%>
<div class="modal fade" id="modal_actor_import" role="dialog" aria-labelledby="modal_actor_import" aria-hidden="true"><div class="modal-dialog"><div class="modal-content"><div class="modal-body"><form id="form_import" method="post" action="import1.htm" enctype="multipart/form-data"><input type="file" name="impfile"/><div class="modal-footer"><button type="submit" class="btn btn-primary">保存</button><button type="button" class="btn btn-default" data-dismiss="modal">关闭</button></div></form></div></div></div></div>

隐藏显示：

        var validator = $("#form_import").validate({submitHandler: function (form) {$(form).ajaxSubmit({dataType: "json",success: function (data) {if (data.success && !data.errorMsg) {validator.resetForm();$('#modal_actor_import').modal('hide');$("#btn_search").click();} else {$("#select_message").text(data.errorMsg);$("#alertmod_table_actor_mod").show();}}});}});

Controller中:

@RequestMapping("/import1")public void import1 (MultipartFile impfile,HttpServletResponse response) throws Exception {//      创建空的工作薄HSSFWorkbook workbook = new HSSFWorkbook(impfile.getInputStream());//       获取表HSSFSheet sheetAt = workbook.getSheetAt(0);//       获取最后一个交表int lastRowNum = sheetAt.getLastRowNum();for (int i = 1; i <=lastRowNum; i++) {HSSFRow row = sheetAt.getRow(i);String name = row.getCell(0).getStringCellValue();int filmLength = (int)row.getCell(1).getNumericCellValue();String spec = row.getCell(2).getStringCellValue();String bir = row.getCell(3).getStringCellValue();String state = row.getCell(4).getStringCellValue();String img = row.getCell(5).getStringCellValue();String cname = row.getCell(6).getStringCellValue();int cid;Complees b = new Complees();b.setName(cname);List<Complees>  list=compleesMapper.select(b);if(list==null||list.size()==0){compleesMapper.insertSelective(b);cid=b.getCid();}else {cid=list.get(0).getCid();}
////                1姓名为黑海，部门为随时约---导入数据库    if(name.equals("黑海")&&cid==1){
//
//              }
//              2导入状态为是的信息，导入数据库
//              if(state.equals("是")){
//
//              }//大于2012年的导入数据库Date d2 = new SimpleDateFormat("yyyy-MM-dd").parse("2012-10-10");Date d1 = new SimpleDateFormat("yyyy-MM-dd").parse(bir);
//                if(d1.compareTo(d2)>0){
//
//                }Actore a = new Actore();a.setName(name);a.setState(state.equals("是")?1:0);a.setImg(img);a.setFilmLength(filmLength);a.setBir(d1);a.setCid(cid);a.setSpec(spec);actoreService.addActore(a);}//8.给前端返回结果JSONObject result=new JSONObject();result.put("success", true);WriterUtil.write(response, result.toString());}

导出前端：

导出$("#btn_export").click(function () {location.href = "export1.htm";});//导入$("#btn_import").click(function () {$('#modal_actor_import').modal('show');});

后台：

 @RequestMapping("/export1")public void export1(HttpServletResponse response) throws Exception {//创建空的工作薄HSSFWorkbook workbook = new HSSFWorkbook();//       创建空的表HSSFSheet sheet = workbook.createSheet();//创建一个数组String[] tital = {"姓名", "个数", "爱好", "时间", "是否上架", "图片", "所属公司"};HSSFRow row = sheet.createRow(0);for (int i = 0; i < tital.length; i++) {row.createCell(i).setCellValue(tital[i]);}//        查询数据库List<Actor> list = actorService.fan3();for (int i = 0; i < list.size(); i++) {row = sheet.createRow(i + 1);row.createCell(0).setCellValue(list.get(i).getName());row.createCell(1).setCellValue(list.get(i).getFilmLength());row.createCell(2).setCellValue(list.get(i).getSpec());row.createCell(3).setCellValue(new SimpleDateFormat("yyyy-MM-dd").format(list.get(i).getBir()));row.createCell(4).setCellValue(list.get(i).getState()==1?"是":"否");row.createCell(5).setCellValue(list.get(i).getImg());row.createCell(6).setCellValue(list.get(i).getCname());}//7.把工作簿对象返回给前端浏览response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("艺人列表.xls", "UTF-8"));response.setHeader("Connection", "close");response.setHeader("Content-Type", "application/octet-stream");workbook.write(response.getOutputStream());workbook.close();}

MQ的配置：

导入两个xml文件：注意在web.xml一定要修改*.否则报错

<param-value>classpath:applicationContext*.xml</param-value>

Controller:

         @Autowiredprivate JmsTemplate  jmsTemplate;@Autowiredprivate Destination   destination;jmsTemplate.send(destination, new MessageCreator() {@Overridepublic Message createMessage(Session session) throws JMSException {String json = JSONObject.toJSONString(actore);TextMessage textMessage = session.createTextMessage();return textMessage;}});

异常总结：

import com.xiaoshu.entity.Actor;
import com.xiaoshu.entity.Actore;
import org.springframework.beans.factory.annotation.Autowired;
