mybatis对象插入一个对象 ？-mybatis报错

"

如题。

import java.io.Serializable; import java.util.Date;

public class Article implements Serializable { private static final long serialVersionUID = 1L; private Integer id; private String typeClass; private String content; private Date publicedDate = new Date(); private String author = "杨志永"; private String title;

public Integer getId()
{
	return id;
}

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

public Date getPublicedDate()
{
	return publicedDate;
}

public void setPublicedDate(Date publicedDate)
{
	this.publicedDate = publicedDate;
}

public String getTypeClass()
{
	return typeClass;
}

public void setTypeClass(String typeClass)
{
	this.typeClass = typeClass;
}

public String getContent()
{
	return content;
}

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

public String getAuthor()
{
	return author;
}

public void setAuthor(String author)
{
	this.author = author;
}

public String getTitle()
{
	return title;
}

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

}

 想要在mybatis中插入这个对象，我这样做无效：

package org.yang.dao;

import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Options;
import org.yang.beans.Article;

public interface ArticleMapper
{
	@Insert("INSERT INTO articles (typeClass, content, publicedDate, author, title) VALUES (#{typeClass}, #{content}, #{publicedDate}, #{author}, #{title})")
	@Options(useGeneratedKeys = true, keyProperty = "id")
	int addNewArticle(Article article);
}

int result = service.addNewArticle( this.getArticle() );

org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  Cause: java.sql.SQLException: Incorrect string value: '\xE9\x9F\xB3\xE4\xB9\x90' for column 'typeClass' at row 1
