SSH整合（Struts2+hibernate+spring）

1、创建表

create table t_user(
  id int primary key auto_increment,
  username varchar(50),
  password varchar(32),
  age int
);

2、导入jar包

2.1 struts包

2.2 spring包

1  基础：4+1 ， beans、core、context、expression ， commons-logging (struts已经导入)

2  AOP：aop联盟、spring aop 、aspect规范、spring aspect

3  db：jdbc、tx

4  测试：test

5 web开发：spring web

6 驱动：mysql

7 连接池：c3p0

8 整合hibernate：spring orm

2.3   hibernate

hibernate3.jar                核心

\lib\required                 必须

2.4 log日志整合

l  整合log4j

导入 log4j...jar (struts已经导入)

整合（过渡）：slf4j-log4j12-1.7.5.jar

2.5   二级缓存

核心：ehcache-1.5.0.jar

依赖：

backport-util-concurrent-2.1.jar

commons-logging  (存在)

删除重复jar包：版本较低的

3.spring整合hibernate

3.1 po类

package com.alice.ssh.domain;

public class User {
    private Integer id;
    private String username;
    private String password;
    private Integer age;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    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;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    @Override
    public String toString() {
        return "User [id=" + id + ", username=" + username + ", password="
                + password + ", age=" + age + "]";
    }

}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    <hibernate-mapping package="com.alice.ssh.domain">
       <class name="User" table="t_user">
          <id name="id">
             <generator class="native"></generator>
          </id>
          <property name="username" type="string"></property>
           <property name="password" type="string"></property>
            <property name="age" ></property>

       </class>
    </hibernate-mapping>

3.2 dao层

spring提供 HibernateTemplate 用于操作PO对象，类似Hibernate Session对象

package com.alice.ssh.dao;

import com.alice.ssh.domain.User;

public interface IUserDao {
    public void save(User user);
}

package com.alice.ssh.dao.impl;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.alice.ssh.dao.IUserDao;
import com.alice.ssh.domain.User;

//底层需要SessionFactory，自动创建HibernateTemplate模板
public class UserDaoImpl extends HibernateDaoSupport implements IUserDao{

//    private HibernateTemplate hibernateTemplate;

//    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
//        this.hibernateTemplate = hibernateTemplate;
//    }

    public void save(User user) {
        this.getHibernateTemplate().save(user);
        System.out.println("dao+"+user);
    }

}

3.3 service层

package com.alice.ssh.service;

import com.alice.ssh.domain.User;

public interface UserService {
   public void register(User user);

}

package com.alice.ssh.service.impl;

import com.alice.ssh.dao.IUserDao;
import com.alice.ssh.domain.User;
import com.alice.ssh.service.UserService;

public class UserServiceImpl implements UserService{

    private IUserDao userDao;

    public void setUserDao(IUserDao userDao) {
        this.userDao = userDao;
    }

    public void register(User user) {
         userDao.save(user);
         System.out.println("service+"+user);
    }

}

spring整合hibernate分两种情况：

一种是有hibernate.cfg.xml

一种没有hibernate.cfg.xml

先说有hibernate配置文件的：

hibernate.cfg.xml文件为：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>
       <session-factory>
         <!-- 基本四项 -->
         <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
         <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/spring</property>
         <property name="hibernate.connection.username">root</property>
         <property name="hibernate.connection.password">alice</property>

         <!-- 配置方言 -->
         <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

         <!-- sql输出 -->
         <property name="hibernate.show_sql">true</property>
         <property name="hibernate.format_sql">true</property>

         <!-- 自生成表格 -->
         <property name="hibernate.hbm2ddl.auto">update</property>

         <!-- 绑定线程 -->
         <property name="hibernate.current_session_context_class">thread</property>

         <!-- 导入映射文件 -->
         <mapping resource="com/alice/ssh/domain/User.hbm.xml"/>
       </session-factory>
    </hibernate-configuration>

这种情况下，spring配置文件写成如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<aop:config>
   <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/>
</aop:config>
</beans>

无hibernate配置文件的，现在比较常用，这种情况如下配置：

删除hibernate.cfg.xml

在applicationContext.xml中配置相应的文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<aop:config>
   <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.alice.ssh.service..*.*(..))"/>

</beans>

修改dao，使用HibernateDaoSupport

// 底层需要SessionFactory，自动创建HibernateTemplate模板
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

    @Override
    public void save(User user) {
        this.getHibernateTemplate().save(user);
    }

测试用例：

package com.alice.ssh.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alice.ssh.domain.User;
import com.alice.ssh.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicactionContext.xml")
public class UserTest {
    @Autowired
    private UserService userService;

    @Test
    public void test(){
        User user = new User();
        user.setUsername("llili");
        user.setPassword("124354");
        user.setAge(18);

        userService.register(user);
    }

}

4、  struts整合spring

4.1 spring创建action

1.编写action类，并将其配置给spring ，spring可以注入service

package com.alice.ssh.web.action;

import com.alice.ssh.domain.User;
import com.alice.ssh.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends ActionSupport implements ModelDriven<User>{
    /**
     *
     */
    private static final long serialVersionUID = 1L;
    //1 封装数据
        private User user = new User();

        public User getModel() {
            return user;
        }

        //2 service
        private UserService userService;
        public void setUserService(UserService userService) {
            this.userService = userService;
        }

        /**
         * 注册
         * @return
         */
        public String register(){
            userService.register(user);
            return "success";
        }

}

applicationContex.xml中注入action

2.编写struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
  <!-- 开发模式 -->
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        <!-- 底层自动从spring容器中通过名称获得内容， getBean("userAction") -->
        <action name="userAction_*" class="userAction" method="register">
            <result name="success">/success.jsp</result>
        </action>
    </package>
</struts>

3.表单jsp页面

<form action="${pageContext.request.contextPath}/userAction_register" method="post">
        用户名：<input type="text" name="username"/> <br/>
        密码：<input type="password" name="password"/> <br/>
        年龄：<input type="text" name="age"/> <br/>
        <input type="submit" />
    </form>

4.web.xml 配置

1.确定配置文件contextConfigLocation

2.配置监听器 ContextLoaderListener

3.配置前端控制器 StrutsPrepareAndExecuteFitler

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name></display-name>
   <!-- 1 确定spring xml位置 -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicactionContext.xml</param-value>
  </context-param>
  <!-- 2 spring监听器 -->
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 3 struts 前端控制器 -->
  <filter>
      <filter-name>struts2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
    <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

4.2 struts创建action

1  删除spring action配置

2 struts <action class="全限定类名">

<struts>
  <!-- 开发模式 -->
    <constant name="struts.devMode" value="true" />

    <package name="default" namespace="/" extends="struts-default">
        <!-- 底层自动从spring容器中通过名称获得内容， getBean("userAction") -->
        <action name="userAction_*" class="com.alice.ssh.web.action.UserAction" method="register">
            <result name="success">/success.jsp</result>
        </action>
    </package>
</struts>
