增加lunwenBean.java

package classes;

public class lunwenBean {
    private String title;
    private String zhaiyao;
    private String zuozhe;
    private String lianjie;
    private String time;
    public lunwenBean(String title, String zhaiyao, String zuozhe, String lianjie, String time) {
        super();
        this.title = title;
        this.zhaiyao = zhaiyao;
        this.zuozhe = zuozhe;
        this.lianjie = lianjie;
        this.time = time;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getZhaiyao() {
        return zhaiyao;
    }
    public void setZhaiyao(String zhaiyao) {
        this.zhaiyao = zhaiyao;
    }
    public String getZuozhe() {
        return zuozhe;
    }
    public void setZuozhe(String zuozhe) {
        this.zuozhe = zuozhe;
    }
    public String getLianjie() {
        return lianjie;
    }
    public void setLianjie(String lianjie) {
        this.lianjie = lianjie;
    }
    public String getTime() {
        return time;
    }
    public void setTime(String time) {
        this.time = time;
    }
    
}

改进servlet.java:

package classes;
