和讯网人物信息采集程序

对于单站点或是数量较少的站点的信息采集来说,使用JSoup+CSSPath是非常不错的选择,使用Firefox的插件Firebug进行页面结构分析,可以很容易地得到待采集内容的CSSPath。对于更复杂的情况,我们就需要引入专业的网络爬虫Nutch来完成页面的抓取,当然解析网页的工作还是使用JSoup+CSSPath。我们这里看一个和讯网人物信息采集的例子:

 

模型类:

 

public class Person {
    private String name;
    //基本信息
    private Map<String, String> basicInfos;
    //教育经历
    List<String> educations;
    //工作经历
    List<String> jobs;
    //重要事件
    List<String> importants;
    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Map<String, String> getBasicInfos() {
        return basicInfos;
    }
    public void setBasicInfos(Map<String, String> basicInfos) {
        this.basicInfos = basicInfos;
    }
    public List<String> getEducations() {
        return educations;
    }
    public void setEducations(List<String> educations) {
        this.educations = educations;
    }
    public List<String> getJobs() {
        return jobs;
    }
    public void setJobs(List<String> jobs) {
        this.jobs = jobs;
    }
    public List<String> getImportants() {
        return importants;
    }
    public void setImportants(List<String> importants) {
        this.importants = importants;
    }
}
