使用请求包装器RequestWrapper 对博客内容进行编码

package model;

public class article {
	private int id;
	private  String title;
	private  String content;
	
	public article() {
		super();
		// TODO 自动生成的构造函数存根
	}

	public int getId() {
		return id;
	}

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

	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;
	}

}
