一、引入Struts的jar包，spring的jar包，hibernate的jar包，Apache的一些jar包，还有加入struts2-spring-plugin-2.3.28.jar这个插件jar包，截图如下：

当然现在的Java开发都流行maven管理了，我这里只是找点从前的感觉，嫌烦的话就用maven，配置相关的jar包即可

二、web.xml的配置

     
         
      
       ssh_01000
          
              
       
        index.html
               
       
        index.htm
               
       
        index.jsp
               
       
        default.html
               
       
        default.htm
               
       
        default.jsp
           
          
          
              
       
        contextConfigLocation
               
               
       
        classpath:beans.xml
           
          
              
       
        org.springframework.web.context.ContextLoaderListener
           
              
          
              
       
        openSessionInView
               
       
        org.springframework.orm.hibernate5.support.OpenSessionInViewFilter
               
                   
        
         sessionFactoryBeanName
                    
        
         sessionFactory
                
           
          
              
       
        openSessionInView
               
       
        /*
           
          
          
              
       
        struts2
               
       
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
           
          
              
       
        struts2
               
       
        /*
           
          
          
              
       
        Spring character encoding filter
               
       
        org.springframework.web.filter.CharacterEncodingFilter
               
                   
        
         encoding
                    
        
         utf-8
                
           
          
              
       
        Spring character encoding filter
               
       
        /*
           
      
     

三、Struts.xml

     
         
          
          
          
          
                  
              
                   
                        
         
           　　　　　　　　　　　　　
                               
          fineUser                
                     
                
              
                   
       
        /WEB-INF/jsp/error.jsp
               　　　　　
               
                   
                
        注释结束-->     
           　　
               
                   
                    
                     
                        
                         /success.jsp            
                                                   
        
         /register.jsp
                
                        
                   
                        
                         /showusers.jsp            
                                
        
         /register.jsp
                
           
                  
     

四、spring的配置文件

     
                 
              
           
              
              
           
              
          
              
           
              
              
               
               
               
           
          
              
               
        　　　　　
                         
                   
                        
         
          youth.hong.User
                     
                
               
                   
                        
         
          org.hibernate.dialect.MySQL5Dialect
                         
         
          true
                         
         
          true
                         
         
          update
                     
                
           
          
          
          
          
              
           
          
          
          
              
           
              
              
          
     

五、Java类,这里就做个登录注册的来说明ssh的整合

1、JavaBean类User.java

package youth.hong;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;//hibernate注解@Entitypublic class User {    private int id;    private int pid;    public int getPid() {        return pid;    }    public void setPid(int pid) {        this.pid = pid;    }    @Id    @GeneratedValue(strategy=GenerationType.IDENTITY)    public int getId() {        return id;    }        public void setId(int id) {        this.id = id;    }    private String username;        private String password;    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }        }

2、Action类

package youth.hong;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;@SuppressWarnings("serial")public class Check extends ActionSupport implements ModelDriven
     
       {        private User user = new User();        /*private String username;        private String password;                //private ClassPathXmlApplicationContext applicationContext;        public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }*/    private UserServiceDao userService;    public UserServiceDao getUserService() {        return userService;    }    public void setUserService(UserServiceDao userService) {        this.userService = userService;    }    public String fineUser() {        int id = user.getId();        System.out.println(id);        user = userService.loadById(id);        return "showoneuser";    }    public void setUser(User user) {        this.user = user;    }    @Override    public String execute() throws Exception {//        applicationContext = new ClassPathXmlApplicationContext("beans.xml");//        UserServiceDao userService = (UserServiceDao)applicationContext.getBean("userService");        System.out.println(userService);        System.out.println(user.getPid());        System.out.println(user.getUsername());        boolean t = userService.save(user);        if(t) {            this.addFieldError("usererror", "用户名冲突，注册失败！");            return INPUT;        }        return SUCCESS;    }    public User getUser() {        return user;    }    @Override    public User getModel() {                return user;    }        }
     

3、UserService接口类

package youth.hong;import java.util.List;public interface UserServiceDao {        public UserDao getUserDao();    public void setUserDao(UserDao userDao);        public boolean save(User user);        public boolean isExists(User user);        public List
     
       getUsers();        public User loadById(int id);}
     

4、UserServiceImpl类

package youth.hong;import java.util.List;import org.springframework.transaction.annotation.Transactional;public class UserServiceImpl implements UserServiceDao {        private UserDao userDao;    public UserDao getUserDao() {        return userDao;    }    public void setUserDao(UserDao userDao) {        this.userDao = userDao;    }    @Transactional    public boolean save(User user) {        boolean t = isExists(user);        if(t) {            return t;        }        userDao.save(user);        return false;    }    @Override    public boolean isExists(User user) {        return userDao.isExists(user);    }    @Override    public List
     
       getUsers() {        return userDao.getUsers();    }    @Override    @Transactional    public User loadById(int id) {        return userDao.loadById(id);    }    }
     

5、UserDao类

package youth.hong;import java.util.List;public interface UserDao {    public void save(User user);    public boolean isExists(User user);    public List
     
       getUsers();    public User loadById(int id);}
     

6、UserDaoImpl类

package youth.hong;import java.util.List;public class UserDaoImpl extends SuperDao implements UserDao {                @Override    public void save(User user) {        this.getHibernateTemplate().save(user);    }    @Override    public boolean isExists(User user) {        String sql = "from User u where u.username=?";        @SuppressWarnings("unchecked")        List
     
       users = (List
      
       ) this.getHibernateTemplate().find(sql, user.getUsername());        if(users.size() > 0) {            return true;        }        return false;    }    @SuppressWarnings("unchecked")    @Override    public List
       
         getUsers() {        String sql = "from User";        return (List
        
         ) this.getHibernateTemplate().find(sql);    }    @Override    public User loadById(int id) {                User user = (User)this.getHibernateTemplate().load(User.class,id);        //System.out.println(user);        return user;    }}
        
       
      
     

7、SuperDao

package youth.hong;import org.hibernate.SessionFactory;/** * 给其他的Dao类继承，使用它注入sessionFactory，省去重复注入的麻烦 * @author may * */public class SuperDao extends org.springframework.orm.hibernate5.support.HibernateDaoSupport {        public void setSuperSessionFactory(SessionFactory sessionFactory) {        super.setSessionFactory(sessionFactory);    }}

8、列出数据库中存在的User信息

package youth.hong;import java.util.List;import com.opensymphony.xwork2.ActionSupport;@SuppressWarnings("serial")public class ShowUsers extends ActionSupport {    private List
     
       users = null;        private UserServiceDao userService;    public UserServiceDao getUserService() {        return userService;    }    public void setUserService(UserServiceDao userService) {        this.userService = userService;    }    public List
      
        getUsers() {        return users;    }    public void setUsers(List
       
         users) {        this.users = users;    }    @Override    public String execute() throws Exception {        users = userService.getUsers();        System.out.println(users.size());        return SUCCESS;        }            }
       
      
     

六、字段校验，跟action同目录

     
             
              
       username        
       true 　　　　 
               
           
              
              
       username        
               
       
        error
           
          
              
                   
        true            
                
           
          
     

七、全局i18n国际化配置信息文件，放在src下

global_en_US.properties

user.username=usernameuser.password=password

global_zh_CN.properties

user.username=\u7528\u6237\u540Duser.password=\u5BC6 \u7801requiredstringusername=\u7528\u6237\u540D\u4E0D\u80FD\u4E3A\u7A7Arequiredstringpassword=\u5BC6\u7801\u4E0D\u80FD\u4E3A\u7A7A

 

 八、视图界面

Register.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %><%System.out.println(request.getContextPath()); %>
     
     
         
          
          
          
      
     
     
     

用户列表界面

<%@page import="youth.hong.ShowUsers"%><%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %>
     
             
     
     
用户列表
