获取高校信息

说明

开发的系统中，高校信息的作用是个人选的教育经历打上标签，方便筛选优质人才。 传统一些的方式就是985/211，但是现在主流的方式是双一流。尽管如此，用985/211来筛选也存在很大程度上的合理性，所以从多个角度都进行了查询。

数据来源方面，使用了阳关高考网和中国教育在线两个网站。 阳关高考网：https://gaokao.chsi.com.cn/sch/search.do 中国教育在线：https://daxue.eol.cn/ 查询流程： 1 通过阳关高考网选择民办大学，将所有民办大学筛选出来 2 通过中国教育在线筛选出985和211院校 3 查询阳光高考网数据列表，每个学校都判断是否是民办or985/211，打上标签

技术说明

开发语言选择的是Java，pom.xml中引入了jsoup用来网络请求

		
            org.jsoup
            jsoup
            1.12.1
        

高校表结构设计

直接将数据内容保存即可，单一表

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

/**

辅助方法

用来判断某个学校是否是985/211，之所以没直接对比学校名称，是考虑到如果某学校是985/211，那么分校也理应是985/211。

	private boolean schoolContain(String name, List school) {
		boolean contain =false;
		for(String item : school) {
			if(name.contains(item)) {
				contain = true;
				break;
			}
		}
		return contain;
	}

代码流程

获取985院校列表

		//985院校
		String url = "https://daxue.eol.cn/985.shtml";
		Document doc = Jsoup.connect(url).get();
		List school985 = new ArrayList();
		Elements eles = doc.getElementsByTag("tbody").first().getElementsByTag("tr");
		for(Element ele : eles) {
			Elements items = ele.getElementsByTag("td");
			school985.add(items.get(items.size()-3).text());
		}

获取211院校列表

		//211院校
		url = "https://daxue.eol.cn/211.shtml";
		doc = Jsoup.connect(url).get();
		List school211 = new ArrayList();
		eles = doc.getElementsByTag("tbody").first().getElementsByTag("tr");
		for(Element ele : eles) {
			Elements items = ele.getElementsByTag("td");
			school211.add(items.get(items.size()-3).text());
		}

获取民办大学列表

		// 民办大学
		url = "https://gaokao.chsi.com.cn/sch/search.do?searchType=1&yxmc=&ssdm=&yxls=&xlcc=&yxjbz=2";
		doc = Jsoup.connect(url).get();
		eles = doc.getElementById("PageForm").getElementsByTag("li");
		Element ele = eles.get(eles.size() - 3);
		int count = Integer.parseInt(ele.text());
		List minbanSchoolName = new ArrayList();
		for (int i = 0; i < count; i++) {
			url = "https://gaokao.chsi.com.cn/sch/search--searchType-1,yxjbz-2,start-" + (i * 20) + ".dhtml";
			doc = Jsoup.connect(url).get();
			eles = doc.getElementsByClass("ch-table").first().getElementsByTag("tr");
			for (int j = 1, num = eles.size(); j < num; j++) {
				Elements items = eles.get(j).getElementsByTag("td");
				minbanSchoolName.add(items.get(0).text());
			}
			Thread.sleep(2000);
		}

查询高校列表并保存到数据库

		// 查询列表数据
		url = "https://gaokao.chsi.com.cn/sch/search.do";
		doc = Jsoup.connect(url).get();
		eles = doc.getElementById("PageForm").getElementsByTag("li");
		ele = eles.get(eles.size() - 3);
		count = Integer.parseInt(ele.text());
		for (int i = 0; i < count; i++) {
			url = "https://gaokao.chsi.com.cn/sch/search--start-" + (i * 20) + ".dhtml";
			doc = Jsoup.connect(url).get();
			eles = doc.getElementsByClass("ch-table").first().getElementsByTag("tr");
			for (int j = 1, num = eles.size(); j < num; j++) {
				Elements items = eles.get(j).getElementsByTag("td");
				
				University school = new University();
				school.setCity(items.get(1).text());
				school.setCreateTime(Dates.now());
				school.setLeadingUniversity(StringUtil.isBlank(items.get(4).text())?0:1);
				school.setLeadingDisciplines(StringUtil.isBlank(items.get(5).text())?0:1);
				if(minbanSchoolName.contains(items.get(0).text())) {
					school.setFeature("民办");
				} else {
					if(schoolContain(items.get(0).text(), school985)) {
						school.setFeature("985|211");
					} else if(schoolContain(items.get(0).text(), school211)) {
						school.setFeature("211");
					}
				}
				school.setInstitute(StringUtil.isBlank(items.get(6).text())?0:1);
				school.setIsDelete(0);
				school.setLevel(items.get(3).text());
				school.setName(items.get(0).text());
				school.setOwner(items.get(2).text());
				schoolRepository.save(school);
				
			}
			Thread.sleep(2000);
