注解 SSHXML---sprong+springmvc+struts+hibirthary 注解整合

项目架构

主要是配置文件的删除

1.更改实体类并删除小配置

package cn.happy.entity;

import javax.persistence.*;

/**
 * Created by CY on 2018/1/5.
 */
@Entity
@Table(name = "Dept")
public class Dept {
    @Id
    @GeneratedValue //native
    private Integer deptno;
    @Column
    private  String deptname;

    public Integer getDeptno() {
        return deptno;
    }

    public void setDeptno(Integer deptno) {
        this.deptno = deptno;
    }

    public String getDeptname() {
        return deptname;
    }

    public void setDeptname(String deptname) {
        this.deptname = deptname;
    }
}

2.dao层的实现类添加注解

package cn.happy.dao;

import cn.happy.entity.Dept;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import javax.annotation.Resource;

/**
 * Created by CY on 2018/1/5.
 */
@Repository("deptDao")
public class DeptDaoImpl implements IDeptDao {
    //事件  植入SessionFactory
    @Resource(name = "sessionFactory")
    private SessionFactory sessionFactory;
    public void addDept(Dept dept) {
        Session session = sessionFactory.getCurrentSession();
        session.save(dept);
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

3.service的实现类添加注解

package cn.happy.service;

import cn.happy.dao.IDeptDao;
import cn.happy.entity.Dept;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;

/**
 * Created by CY on 2018/1/5.
 */
@Service("deptService")
public class DeptServiceImpl implements IDeptService {
   @Resource(name = "deptDao")
    private IDeptDao deptDao;

    @Transactional
    public void addDept(Dept dept) {
         deptDao.addDept(dept);
    }

    public IDeptDao getDeptDao() {
        return deptDao;
    }

    public void setDeptDao(IDeptDao deptDao) {
        this.deptDao = deptDao;
    }
}

4.action添加注解

package cn.happy.action;

import cn.happy.entity.Dept;
import cn.happy.service.IDeptService;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import javax.annotation.Resource;

/**
 * Created by CY on 2018/1/5.
 */
@Controller("deptAction")
@ParentPackage("struts-default")
@Namespace("/")
@Scope("prototype")
public class DeptAction extends ActionSupport {
    private Dept dept;
    @Resource(name = "deptService")
    private IDeptService deptService;
    @Action(value = "add",results = {@Result(name = "success",location = "/jsp/index.jsp")})
    public  String add(){
        deptService.addDept(dept);
        return SUCCESS;
    }

    public Dept getDept() {
        return dept;
    }

    public void setDept(Dept dept) {
        this.dept = dept;
    }

    public IDeptService getDeptService() {
        return deptService;
    }

    public void setDeptService(IDeptService deptService) {
        this.deptService = deptService;
    }
}

5.applicationContext.xml删除dao层和service的注入并添加包扫描器
