5.dao层的基本配置和书写
@Repository("dao层的属性注入名称")
public class 实现类名 extends HibernateDaoSupport implements 接口名{
//固定格式
@Resource(name="sessionFactory")
public void setSF(SessionFactory sf) {
super.setSessionFactory(sf);
}
}
6.service层基本配置和书写
@Service("service层的属性注入名称")
//下面的属性是设置是否只读，对于不只读的方法将true改为false
@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=true)
public class 实现类名 implements 接口名{
@Resource(name="dao层的属性注入名称")
private StartPageDao spd;
}
7.action层基本配置和书写
@Scope("prototype")
//设置多例
@Controller("action层的属性注入名称")
public class 实现类名 extends ActionSupport{
@Resource(name="service层的属性注入名称")
private StartPageService startpageservice;
//提供了一个供给发送前端ajax的方法
public String index() throws Exception{
// 1.访问service层的方法
List<StartPage> sp = (List<StartPage>) startpageservice.findStartImage();
// 2.将数据放回给前端
Gson gson = new Gson();
String json = gson.toJson(sp);
ServletActionContext.getResponse().setContentType("application/json;charset=utf-8");
ServletActionContext.getResponse().getWriter().write(json);
return null;
}
}
