------解决方案--------------------
你这写法怎么觉的异样呢，应该是News new=(News)se.load(News.class,new Integer(1));或是
News new=(News)se.load(ne.getClass(),new Integer(1));

------解决方案--------------------
给实体类News加2个构造方法，一个有参数的和一个无参数的
public News(){
}
public News(int newId,String newTitle,String newContent){
 this.newId=newId;
 this.newTitle=newTitle;
 this.newContent=newContent;

}
