这篇主要讲解spring + struts2 + hibernate ：

目录结构如下：

t_role

t_user

 

1.新建 web项目 ：spring_ssh

2.在 WebRoot/WEB-INF/lib 下 导入jar包

antlr-2.7.7.jaraopalliance.jarasm-3.3.jarasm-commons-3.3.jarasm-tree-3.3.jaraspectjweaver.jarcommons-fileupload-1.2.2.jarcommons-io-2.0.1.jarcommons-lang3-3.1.jarcommons-logging.jardom4j-1.6.1.jarfreemarker-2.3.19.jarhibernate-commons-annotations-4.0.5.Final.jarhibernate-core-4.3.10.Final.jarhibernate-jpa-2.1-api-1.0.0.Final.jarjandex-1.1.0.Final.jarjavassist-3.18.1-GA.jarjboss-logging-3.1.3.GA.jarjboss-logging-annotations-1.2.0.Beta1.jarjboss-transaction-api_1.2_spec-1.0.0.Final.jarjstl-1.2.jarmysql-connector-java-5.1.20-bin.jarognl-3.0.5.jarspring-aop-4.1.6.RELEASE.jarspring-aspects-4.1.6.RELEASE.jarspring-beans-4.1.6.RELEASE.jarspring-context-4.1.6.RELEASE.jarspring-core-4.1.6.RELEASE.jarspring-expression-4.1.6.RELEASE.jarspring-jdbc-4.1.6.RELEASE.jarspring-orm-4.1.6.RELEASE.jarspring-tx-4.1.6.RELEASE.jarspring-web-4.1.6.RELEASE.jarstruts2-core-2.3.4.jarstruts2-spring-plugin-2.3.4.jarxwork-core-2.3.4.jar

3.编写vo类 :Role.java , User.java

Role.java

package cn.vincent.vo;import java.io.Serializable;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;@Entity@Table(name="t_role")public class Role implements Serializable {    @Id    @GeneratedValue(strategy=GenerationType.AUTO)    private int id;    private String name;    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;    }    }

User.java

package cn.vincent.vo;import java.io.Serializable;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.JoinColumn;import javax.persistence.ManyToOne;import javax.persistence.Table;@Entity@Table(name="t_user")public class User implements Serializable {    @Id    @GeneratedValue(strategy=GenerationType.AUTO)    private int id;    private String name;    private int age;    @ManyToOne    @JoinColumn(name="roleId")    private Role role;    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 int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    public Role getRole() {        return role;    }    public void setRole(Role role) {        this.role = role;    }    }

4.编写 dao 

UserDao.java

package cn.vincent.dao;import java.util.List;import cn.vincent.vo.User;public interface UserDao {    public List
      
        findAll();}
      

UserDaoImpl.java

package cn.vincent.dao.impl;import java.util.List;import org.hibernate.SessionFactory;import cn.vincent.dao.UserDao;import cn.vincent.vo.User;public class UserDaoImpl implements UserDao{    private SessionFactory sessionFactory;        @Override    public List
      
        findAll() {        return sessionFactory.getCurrentSession()                .createQuery("from User").list();    }    public void setSessionFactory(SessionFactory sessionFactory) {        this.sessionFactory = sessionFactory;    }        }
      

5.编写 service

UserService.java

package cn.vincent.service;import java.util.List;import cn.vincent.vo.User;public interface UserService {    public List
      
        findAll();}
      

UserServiceImpl.java

package cn.vincent.service.impl;import java.util.List;import cn.vincent.dao.UserDao;import cn.vincent.service.UserService;import cn.vincent.vo.User;public class UserServiceImpl implements UserService {    private UserDao userDao;    @Override    public List
      
        findAll() {        return userDao.findAll();    }        public void setUserDao(UserDao userDao) {        this.userDao = userDao;    }}
      

6.编写 action

package cn.vincent.action;import java.util.List;import com.opensymphony.xwork2.Action;import cn.vincent.service.UserService;import cn.vincent.vo.User;public class UserAction {    private List
      
        list;    private UserService userService;        public String list(){        list = userService.findAll();        return Action.SUCCESS;    }            public List
       
         getList() {        return list;    }    public void setList(List
        
          list) {        this.list = list;    }    public UserService getUserService() {        return userService;    }    public void setUserService(UserService userService) {        this.userService = userService;    }        }
        
       
      

7.编写 spring 配置文件

applicationContext-dao.xml

     
       
            
             
             
             
         
        
        
            
             
             
                 
                      
         
          org.hibernate.dialect.MySQLDialect
                       
         
          true
                       
         
          true
                   
              
             
             
                 
                      
         
          cn.vincent.vo.User
                       
         
          cn.vincent.vo.Role
                   
              
         
        
        
        
            
         
        
        
            
                 
                  
                  
                  
                  
              
         
        
          
              
               
               
           
          
     

applicationContext-asd.xml

8.编写 struts2 配置文件

struts.xml

         
         
              
                   
        
         /list.jsp
                
           
      
     

9.编写 web.xml 

     
         
          
              
       
        contextConfigLocation
               
       
        classpath:applicationContext-*.xml
           
          
          
              
       
        org.springframework.web.context.ContextLoaderListener
           
          
              
       
        osiv
               
       
        org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
               
                   
        
         sessionFactoryBeanName
                    
        
         sessionFactory
                
           
          
              
       
        osiv
               
       
        *.action
           
          
              
       
        struts2
               
       
        org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
           
          
              
       
        struts2
               
       
        /*
           
          
     

10.编写 jsp

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>

${bean.id }
                    
${bean.name }
                    
            ${bean.age }            
                        
            ${bean.role.name }            
               
                  
     

11. 运行web项目
