似乎每个类只能用Jsoup创建一个get请求，因为当我用CITYPARKSURL换成CITYPARKSURL2时，我放在getParkNames()中的那个会编译，另一个会出错。
我在IntelliJ中运行了这段代码，但当我把它移到Eclipse中时，它开始给我这些握手错误。有人知道为什么会这样吗？(不幸的是，我不得不在Eclipse中完成我的项目。(
这是我的代码和错误：
public class DublinCityParksParse{
private final String CITYPARKSURL = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park";
private final String CITYPARKSURL1 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=1";
private final String CITYPARKSURL2 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=2";
private final String CITYPARKSURL3 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=3";
private String[] parkNamesHyphs = {"/eamonn-ceannt-park", "/balcurris"};
private List<String> parkNames = new ArrayList<String>();
private ArrayList<String> parkNamesHyphen = new ArrayList<String>();
private List<Park> parks = new ArrayList<Park>();
public DublinCityParksParse() {
getParkNames();
getParkNames1();
}
public void getParkNames() {
try {
Document docGetDetails = Jsoup.connect(CITYPARKSURL).get();
Elements elsClass = docGetDetails.getElementsByClass("search-result__title");
for(Element els : elsClass) {
parkNames.add(els.text());
}
// System.out.println(docGetDetails.toString());
System.out.println(parkNames.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void getParkNames1() {
try {
Document docGetDetails1 = Jsoup.connect(CITYPARKSURL1).get();
Elements elsClass1 = docGetDetails1.getElementsByClass("search-result__title");
for(Element els : elsClass1) {
parkNames.add(els.text());
}
System.out.println(docGetDetails1.toString());
System.out.println(parkNames.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[]args) {
new DublinCityParksParse();
}}

我敢打赌，您在IntelliJ和Eclipse之间运行不同的Java版本，而Eclipse版本是旧的(比如1.7或旧的1.8(。这就是为什么它在第一个IDE中有效，而在第二个IDE中无效。
您应该将JDK更新到当前支持的版本。那些旧版本的Java在当前的TLS/SSL网站上遇到了问题。它们缺少许多密码套件、SNI支持、TLS 1.3支持等。你可以为旧版本修补所有这些，但我无法想象这是你想要做的。
