struts2，hibernate5，spring4整合，以前没有遇到过，整整搞了一天了没找出原因，哪位大神帮帮忙：
页面Struts提示的错误信息如下：
spring的beans.xml里是这么配置的

代码里的结构是HT类接受spring注入template，service基类（泛型类）继承HT并且实现DAOsupport接口（这个接口是泛型接口），service实现类继承service基类并且实现DAOsupport的子接口，具体代码如下：
HT类
public class HT {
private HibernateTemplate ht;
public HibernateTemplate getHt() {
return ht;
}
@Resource
public void setHt(HibernateTemplate ht) {
this.ht = ht;
}
}
DAOsupport接口如下
```public interface DAOSupport {
public void save(T t);
}
基类代码如下：
```public class DAOsupportImpl<T> extends HT implements DAOSupport<T> {
private Class<T> clazz;
public DAOsupportImpl() {
super();
ParameterizedType pt = (ParameterizedType) this.getClass().getGenericSuperclass(); // 获取当前new的对象的
// 泛型的父类
// 类型
clazz = (Class<T>) pt.getActualTypeArguments()[0]; // 获取第一个类型参数的真实类型
System.out.println("clazz ---> " + clazz);
}
@Override
public void save(T t) {
System.out.println("到dao"+t.getClass());
getHt().save(t);
}
public Class<T> getClazz() {
return clazz;
}
public void setClazz(Class<T> clazz) {
this.clazz = clazz;
}
}
service实现类代码如下
public class UserServiceImpl extends DAOsupportImpl<User> implements UserService {
}
action中的方法如下
``` public String save() {
//System.out.println("到action");
ActionContext.getContext().getApplication().remove("users");
this.userService.save(getModel());//model是user的一个实例
return "list";
}
