静态化文件位置注意:

实体类定义:
public class News {
private String title;
private String pubTime;
private String category;
private String newsContent;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getPubTime() {
return pubTime;
}
public void setPubTime(String pubTime) {
this.pubTime = pubTime;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public String getNewsContent() {
return newsContent;
}
public void setNewsContent(String newsContent) {
this.newsContent = newsContent;
}
