java注解1

    本文演示java注解的使用

    1. getDeclaredFields方法

    这个方法返回当前对象中的声明的Filed数组，只返回当前类，不会返回父类的Field. 

public class News extends Article {

	public News(int id, Date createDate, Date modifyDate, String title,
			String content, boolean isPublication) {
		super(id, createDate, modifyDate, title, content, isPublication);
	}
	
}

   

public class Article extends BaseEntry {
	protected String title;// 消息标题
	protected String content;// 消息内容
	protected boolean isPublication; // 是否已发布

	public Article() {
	}

	public Article(int id, Date createDate, Date modifyDate, String title,
			String content, boolean isPublication) {
		super(id, createDate, modifyDate);
		this.title = title;
		this.content = content;
		this.isPublication = isPublication;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getContent() {
		return content;
	}

	public void setContent(String content) {
		this.content = content;
	}
	
	public boolean isPublication() {
		return isPublication;
	}

	public void setPublication(boolean isPublication) {
		this.isPublication = isPublication;
	}

}

 

public class BaseEntry {
	protected int id;// ID
	protected Date createDate;// 创建日期
	protected Date modifyDate;// 修改日期

	public BaseEntry() {
	}

	public BaseEntry(int id, Date createDate, Date modifyDate) {
		this.id = id;
		this.createDate = createDate;
		this.modifyDate = modifyDate;
	}
	public BaseEntry( Date createDate, Date modifyDate) {
		this.createDate = createDate;
		this.modifyDate = modifyDate;
	}

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public Date getCreateDate() {
		return createDate;
	}

	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}

	public Date getModifyDate() {
		return modifyDate;
	}

	public void setModifyDate(Date modifyDate) {
		this.modifyDate = modifyDate;
	}

}
