springMVC的

springMVC在解决乱码想用produces = "text/html;charset=UTF-8"这个时报了这个错，该怎么解决啊？
The attribute produces is undefined for the annotation type RequestMapping
springMVC的跨域请求返回？？？？乱码问题

3种方法
1。构造器注入
public class xx {
private manager manage;
public xx(manager manage){
this.manage= manage;
}
}

2.setter 方法注入
public class xx {
private manager manage;
public void setmanager(manager manage){
this.manage= manage;
}
}

3.接口注入
public interface manager{
public void manage(business business);
}
public class xx {
private business business;
public void manage(business business){
this.business = business;
}
}

Form formPreview = new Form(); public Leaf(string name) : base(name) { } public override void Add(Component c) { Console.WriteLine("Cannot add to a leaf"); } public override void Remove(Component c) { Console.WriteLine("Cannot remove to a leaf"); } public override void Display(int depth) { Console.WriteLine(new string('-',depth)+name); } }
