Spring 4 : 整合 SSH

简介:ssh的整合

 

1       SSH整合

1.1   jar整合

struts:2.3.15.3

hibernate : 3.6.10

spring: 3.2.0

 

1.1.1   struts(jar包导入)

struts-2.3.15.3\apps\struts2-blank\WEB-INF\lib

 

  模板技术  ,一般用于页面静态化

  freemarker:扩展名:*.ftl

  velocity :扩展名  *.vm

1.1.2   spring(jar包导入)

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

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

l    db:jdbc、tx

l    测试:test

l    web开发:spring web

 

l    驱动:mysql

l    连接池:c3p0

 

l    整合hibernate:spring orm

 

 

1.1.3   hibernate(jar包导入)

%h%\hibernate3.jar                     核心

%h%\lib\required                         必须

      

%h%\lib\jpa                                jpa规范 (java persistent api 持久api),hibernate注解开发 @Entity @Id 等

 

l  整合log4j

       导入 log4j...jar (struts已经导入)

       整合(过渡):slf4j-log4j12-1.7.5.jar

l  二级缓存

       核心:ehcache-1.5.0.jar

       依赖:

              backport-util-concurrent-2.1.jar

              commons-logging  (存在)

1.1.4   整合包(jar包导入)

l    spring整合hibernate: spring orm

l    struts 整合spring:struts2-spring-plugin-2.3.15.3.jar

删除重复jar包(39个)

 

1.2   spring整合hibernate:有hibernate.cfg.xml

1.2.1   创建表

create table t_user(

  id int primary key auto_increment,

  username varchar(50),

  password varchar(32),

  age int

);
sql

 

1.2.2   PO 类

 

l  javabean

1 public class User {
2     private Integer id;
3     private String username;
4     private String password;
5     private Integer age;
javaBean

 

l  映射文件

<!DOCTYPE hibernate-mapping PUBLIC

    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

    <class name="com.itheima.domain.User" table="t_user">

        <id name="id">

            <generator class="native"></generator>

        </id>

        <property name="username"></property>

        <property name="password"></property>

        <property name="age"></property>

    </class>

 

</hibernate-mapping>
bean.hbm.xml

 

1.2.3   dao层

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

 

 1 public class UserDaoImpl implements UserDao {
 2 
 3    
 4 
 5     //需要spring注入模板
 6 
 7     private HibernateTemplate hibernateTemplate;
 8 
 9     public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
10 
11         this.hibernateTemplate = hibernateTemplate;
12 
13     }
14 
15  
16 
17     @Override
18 
19     public void save(User user) {
20 
21         this.hibernateTemplate.save(user);
22 
23     }
24 
25  
26 
27 }
dao

 

1.2.4   service层

 1 public class UserServiceImpl implements UserService {
 2 
 3  
 4 
 5     private UserDao userDao;
 6 
 7     public void setUserDao(UserDao userDao) {
 8 
 9         this.userDao = userDao;
10 
11     }
12 
13     @Override
14 
15     public void register(User user) {
16 
17         userDao.save(user);
18 
19     }
20 
21  
22 
23 }
service

 

1.2.5   hibernate.cfg.xml

 1 <session-factory>
 2 
 3         <!-- 1基本4项 -->
 4 
 5         <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

45    
46 
47     </session-factory>
Hibernate.cfg.xml

 

1.2.6   applicationContext.xml

1.3   spring整合hibernate:没有hibernate.cfg.xml 【】

l    删除hibernate.cfg.xml文件,但需要保存文件内容,将其配置spring中

l    修改dao层,继承HibernateDaoSupport

 

1.3.1   修改spring,配置SessionFactory

 1 <!-- 1.1加载properties文件 -->
 2     <!-- 1.2 配置数据源 -->
 3     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

37     </bean>

1.3.2   修改dao,使用HibernateDaoSupport

l  继承HibernateDaoSupport

 1 // 底层需要SessionFactory,自动创建HibernateTemplate模板
 2 
 3 public class UserDaoImpl extends HibernateDaoSupport implements UserDao {
 4 
 5  
 6 
 7    @Override
 8 
 9    public void save(User user) {
10 
11       this.getHibernateTemplate().save(user);
12 
13    }
14 
15  
16 
17 }
dao

 

l  spring 删除模板,给dao注入SessionFactory

1  <!-- 3 dao -->
2 
3    <bean id="userDao" class="com.itheima.dao.impl.UserDaoImpl">
4 
5       <property name="sessionFactory" ref="sessionFactory"></property>
6 
7    </bean>
applicationContext.xml

 

1.4   struts整合spring:spring创建action

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

2.编写struts.xml

3.表单jsp页面

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

 

1.4.1   action类

l  通用

 1 public class UserAction extends ActionSupport implements ModelDriven<User> {
 2 
 3  
 4 
 5    //1 封装数据
 6 
 7    private User user = new User();
 8 
 9  
10 
11    @Override
12 
13    public User getModel() {
14 
15       return user;
16 
17    }
18 
19   
20 
21    //2 service
22 
23    private UserService userService;
24 
25    public void setUserService(UserService userService) {
26 
27       this.userService = userService;
28 
29    }
action

 

l  功能 

 1 /**
 2 
 3     * 注册
 4 
 5     * @return
 6 
 7     */
 8 
 9    public String register(){
10 
11       userService.register(user);
12 
13       return "success";
14 
15    }
View Code

 

1.4.2   spring配置 

1 <!-- 6 配置action -->
2 
3     <bean id="userAction" class="com.itheima.web.action.UserAction" scope="prototype">
4 
5         <property name="userService" ref="userService"></property>
6 
7     </bean>
View Code

1.4.3   struts配置

 1 <struts>
 2 
 3     <!-- 开发模式 -->
 4 
 5     <constant name="struts.devMode" value="true" />
 6 
 7  
 8 
 9     <package name="default" namespace="/" extends="struts-default">
10 
11     <!-- 底层自动从spring容器中通过名称获得内容, getBean("userAction") -->
12 
13     <action name="userAction_*" class="userAction" method="{1}">
14 
15          <result name="success">/messag.jsp</result>
16 
17     </action>
18 
19     </package>
20 
21 </struts>
struts.xml

1.4.4   jsp表单

 1 <form action="${pageContext.request.contextPath}/userAction_register" method="post">
 2 
 3       用户名:<input type="text" name="username"/> <br/>
 4 
 5       密码:<input type="password" name="password"/> <br/>
 6 
 7       年龄:<input type="text" name="age"/> <br/>
 8 
 9       <input type="submit" />
10 
11    </form>
jsp 

1.4.5   配置web.xml

 1 <!-- 1 确定spring xml位置 -->
 2 
 3   <context-param>
 4 
 5     <param-name>contextConfigLocation</param-name>
 6 
 7     <param-value>classpath:applicationContext.xml</param-value>
 8 
 9   </context-param>
10 
11   <!-- 2 spring监听器 -->
12 
13   <listener>
14 
15     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
16 
17   </listener>
18 
19   <!-- 3 struts 前端控制器 -->
20 
21   <filter>

23     <filter-name>struts2</filter-name>
24 
25     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
26 
27   </filter>
28

30 
31     <filter-name>struts2</filter-name>
32 
33     <url-pattern>/*</url-pattern>
34 
35   </filter-mapping>
web.xml

 

1.5   struts整合spring:struts创建action 【】

l  删除spring action配置

l  struts <action class="全限定类名">

<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.itheima.web.action.UserAction" method="{1}">

         <result name="success">/messag.jsp</result>

    </action>

    </package>

 

要求:Action类中,必须提供service名称与 spring配置文件一致。(如果名称一样,将自动注入)

      

 

 

分析:

1. struts 配置文件

       default.properties  ,常量配置文件

       struts-default.xml ,默认核心配置文件

       struts-plugins.xml ,插件配置文件

       struts.xml,自定义核心配置文件

       常量的使用,后面配置项,将覆盖前面的。

2.default.properties  ,此配置文件中确定 按照【名称】自动注入

       /org/apache/struts2/default.properties

      

3. struts-plugins.xml ,struts整合spring

      

              <constant name="struts.objectFactory" value="spring" />

       struts的action将有spring创建

 

总结,之后action有spring创建,并按照名称自动注入
