前端html用一个表单来映射后台多个对象

public class entity1 {

    private String id;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    private String name;

}

public class entity2 {

    private String id;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    private String name;

}

public class entity3 {

    private String id;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    private String name;

}
public class mytestAction extends ActionSupport{

    private entity1 entity1;
    private entity2 entity2;
    private entity3 entity3;

    public String save()
    {
       return "success"

    }
}

表的name值我们用了对象的名称然后序列化表单提交到后台，后台就映射到了三个对象是不是很easy！
