eclipse搭建ssh框架（三）

叁歲伎倆 2023-10-17 11:33 113阅读 0赞

**1、之前2篇已经整合struts2+spring，这篇把hibernate整合进去。**

--------------------

**先给大家看下ssh整合完成后整个项目架构**

![这里写图片描述][SouthEast]

**2、导入hibernate的相关包（已经导入全部包的忽略这一步）**

**在applicationContext.xml中添加hibernate的配置（有些地方改成自己的即可），这样写后，就不用再创建hibernate.properties文件了。**

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close">
            
            <property name="driverClassName" value="com.mysql.jdbc.Driver" />
            
            <property name="url" value="jdbc:mysql://localhost:3306/test" />
            
            <property name="username" value="root" />
            
            <property name="password" value="root" />
        </bean>
        
        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
            <property name="dataSource">
                <ref bean="dataSource" />
            </property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">
                        org.hibernate.dialect.MySQLDialect
                    </prop>
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                    <prop key="hibernate.connection.autocommit">true </prop>
                    <prop key="hibernate.show_sql">true</prop>
                    <prop key="sql_format">true</prop>
                </props>
            </property>
            <property name="mappingResources">
                
                <list>
                    <value>com/entity/User.hbm.xml</value>
                </list>
            </property>
        </bean>

**4、接下来测试对数据库的操作，创建com.entity包，并在下面根据数据库对应的表创建User实体类**

package com.entity;
    
    public class User {
        private int id;
        private String name;
        private String age;
        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 String getAge() {
            return age;
        }
        public void setAge(String age) {
            this.age = age;
        }
    }

**同目录下创建实体类映射User.hbm.xml**

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
        <class name="com.entity.User" table="user">
            
            <id name="id">
                <column name="id" />
                <generator class="increment" />
            </id>
            <property name="name" type="java.lang.String">
                <column name="name" length="36" />
            </property>
            <property name="age" type="java.lang.String">
                <column name="age" length="36"  />
            </property>
        </class>
    </hibernate-mapping>

**5、创建持久层，新建com.dao包，并在下面创建接口UserDao（我已经在里面建立了add的方法）**

package com.dao;
    
    import com.entity.User;
    
    public interface UserDao {
        
        public void add(User user);
    }

**然后同目录下创建实现类UserDaoImpl**

package com.dao;
    
    import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
    
    import com.entity.User;
    
    public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
        
    
    
    
        @Override
        public void add(User user) {
            getHibernateTemplate().save(user);
        }
    
    }

**6、创建service层，新建com.service包，创建接口UserService（我也添加了add方法）**

package com.service;
    
    import com.entity.User;
    
    public interface UserService {
        
        public void add(User user);
    }

**同目录下创建实现类UserServiceImpl**

package com.service;
    
    import com.entity.User;
    import com.dao.UserDao;
    
    public class UserServiceImpl implements UserService {
        
    
    private UserDao userDao;
    
    
        public UserDao getUserDao() {
            return userDao;
        }
    
        public void setUserDao(UserDao userDao) {
            this.userDao = userDao;
        }
        @Override
        public void add(User user) {
            userDao.add(user);
        }
    
    }

**7、在action包下创建RegAction类**

package com.action;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import com.entity.User;
    import com.service.UserService;
    import com.opensymphony.xwork2.ActionSupport;
    
    public class RegAction extends ActionSupport{
        
    
        private UserService userService;
        private String name;
        private String age;
    
    
    //这里采用set注入
        public void setUserService(UserService userService) {
            this.userService = userService;
        }
        public String getName() {
            return name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getAge() {
            return age;
        }
        public void setAge(String age) {
            this.age = age;
        }
    
    
        public String execute(){
            User user=new User();
            user.setName(name);
            user.setAge(age);
            userService.add(user);
            return "success";
    
        }
    
    }

**8、因为这里用的是set注入，所以在applicationContext.xml中添加依赖注入的配置即可，这里给出整个文件**

<?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.springframework.org/schema/beans  
                   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    
    
           
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close">
            
            <property name="driverClassName" value="com.mysql.jdbc.Driver" />
            
            <property name="url" value="jdbc:mysql://localhost:3306/test" />
            
            <property name="username" value="root" />
            
            <property name="password" value="root" />
        </bean>
        
        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
            <property name="dataSource">
                <ref bean="dataSource" />
            </property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">
                        org.hibernate.dialect.MySQLDialect
                    </prop>
                    <prop key="hibernate.hbm2ddl.auto">update</prop>
                    <prop key="hibernate.connection.autocommit">true </prop>
                    <prop key="hibernate.show_sql">true</prop>
                    <prop key="sql_format">true</prop>
                </props>
            </property>
            <property name="mappingResources">
                
                <list>
                    <value>com/entity/User.hbm.xml</value>
                </list>
            </property>
        </bean>
    
    
            <bean id="LoginAction" class="com.action.LoginAction" scope="prototype">
            </bean>
    
    
            
        <bean id="userDao" class="com.dao.UserDaoImpl">
            <property name="sessionFactory" ref="sessionFactory"></property>
        </bean>
        
        <bean id="userService" class="com.service.UserServiceImpl">
            <property name="userDao" ref="userDao"></property>
        </bean>
        <bean id="reg" class="com.action.RegAction" scope="prototype">
            <property name="userService" ref="userService"></property>
        </bean>
        </beans>

**9、在struts.xml加入相应reg的action即可**

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts PUBLIC
       "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
       "http://struts.apache.org/dtds/struts-2.0.dtd">
    <struts>
    <constant name="struts.devMode" value="false" />
       <package name="struts2" extends="struts-default">
            
            <action name="login" class="LoginAction">
                <result name="success">/result.jsp</result>
                <result name="input">/index.jsp</result>
            </action>
            
             <action name="reg" class="reg">
                <result name="success">/regsuccess.jsp</result>
                <result name="input">/reg.jsp</result>
            </action>
        </package>
    
    </struts>

**10、在WebContent下创建2个jsp，reg.jsp和regsuccess.jsp**

--------------------

**reg.jsp**

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>用户演示界面</title>
    </head>
    <body>
        <form action="reg" method="post" name="regForm">
            <table>
                <tr>
                    <td>姓名</td>
                    <td><input type="text" name="name" size="15" /></td>
                </tr>
                <tr>
                    <td>年龄</td>
                    <td><input type="text" name="age" size="15" /></td>
                </tr>
                <tr>
                    <td colspan="2"><input type="submit" value="注册"></td>
                </tr>
    
    
            </table>
        </form>
    
    </body>
    </html>

**11、regsuccess.jsp**

**最后重启tomcat，打开直接访问你的reg.jsp的网址**  
**[http://localhost:8080/SSH/reg.jsp][http_localhost_8080_SSH_reg.jsp]**

![这里写图片描述][SouthEast 1]

**点击注册，这里我偷懒没写注册失败的页面。**

![这里写图片描述][SouthEast 2]

**再去数据库看下，成功添加。（你也可以再写一个select方法，直接在注册成功的页面中展示数据库的信息）**

![这里写图片描述][SouthEast 3]

**这样搭建ssh框架便完成了。**
