    其中，如果没有struts2的公共参数要设置，则struts.xml可为空；hibernate.properties按一般情况设置。

    以下是application.xml

    代码结构图：

    必不可少的类：

package com.jetsum.webtest.common;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class BaseHibernateDaoSupport extends HibernateDaoSupport{
 @Resource(name="sessionFactory")    //为父类HibernateDaoSupport注入sessionFactory的值
    public void setSuperSessionFactory(SessionFactory sessionFactory){
        super.setSessionFactory(sessionFactory);
    }
}

    此类用于代替：

<property name="sessionFactory" ref="sessionFactory"></property>

    bean：

package com.jetsum.common.entity;
import java.util.Date;

public class Person {
 
 private int id;
 
 private String name;
 
 private Date birthday;
 
 private String sex;
 
 public int getId() {
  return id;
 }
 public void setId(int id) {
  this.id = id;
 }
 
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 
 public Date getBirthday() {
  return birthday;
 }
 public void setBirthday(Date birthday) {
  this.birthday = birthday;
 }
 
 public String getSex() {
  return sex;
 }
 public void setSex(String sex) {
  this.sex = sex;
 }
}

    标注dao：

@Repository("personDao")
public class PersonDaoImpl extends BaseHibernateDaoSupport implements PersonDao{

    标注service：

@Repository("personService")
public class PersonServiceImpl implements PersonService {

     注入dao：

@Resource(name="personDao")
 private PersonDao personDao;
（不再需要getter和setter）

    注入service：

@Resource(name="personService")
 private PersonService personService;
（不再需要getter和setter）

    action的annotation：

@Controller @Scope("prototype")
@Results({
 @Result(name="save",location="/success.jsp")
})
public class PersonAction extends ActionSupport
