似乎每个类只能用jsoup创建一个get请求，因为 CITYPARKSURL 为了 CITYPARKSURL2 ，我放进去的那个 getParkNames() 编译，另一个给出错误。
我在intellij中运行了这段代码，但是当我把它移到eclipse中时，它开始给我这些握手错误。有人知道这是为什么吗(不幸的是，我不得不在eclipse中完成我的项目。）
以下是我的代码和错误：

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();
}}
