Spring 03 整合Junit+Web+SSH

2017-06-16 16:59 253 查看
3 整合Junit

 导入jar包

基本 :4+1

测试:spring-test…jar

1.让Junit通知spring加载配置文件

2.让spring容器自动进行注入

 修改测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class TestApp {

@Autowired  //与junit整合,不需要在spring xml配置扫描
private AccountService accountService;

@Test
public void demo01(){
//      String xmlPath = "applicationContext.xml";
//      ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);
//      AccountService accountService =  (AccountService) applicationContext.getBean("accountService");
accountService.transfer("jack", "rose", 1000);
}

}


4 整合web

0.导入jar包

spring-web.xml



1.tomcat启动加载配置文件

servlet –> init(ServletConfig) –>
<load-on-startup>
2

filter –> init(FilterConfig) –> web.xml注册过滤器自动调用初始化

listener –> ServletContextListener –> servletContext对象监听【】

spring提供监听器 ContextLoaderListener –> web.xml
<listener><listener-class>....


如果只配置监听器,默认加载xml位置:/WEB-INF/applicationContext.xml



2.确定配置文件位置,通过系统初始化参数

ServletContext 初始化参数 web.xml

<context-param>
<param-name>contextConfigLocation
<param-value>classpath:applicationContext.xml

<!-- 确定配置文件位置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<!-- 配置spring 监听器,加载xml配置文件 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


3.从servletContext作用域 获得spring容器 (了解)

// 从application作用域(ServletContext)获得spring容器
//方式1: 手动从作用域获取
ApplicationContext applicationContext =
(ApplicationContext) this.getServletContext().getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
//方式2:通过工具获取
ApplicationContext apppApplicationContext2 =
WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());


5 SSH整合

5.1 jar整合

5.2 spring整合hibernate:有hibernate.cfg.xml

5.2.1 创建表

create table t_user(

id int primary key auto_increment,

username varchar(50),

password varchar(32),

age int

);

5.2.2 PO 类



 javabean

public class User {
private Integer id;
private String username;
private String password;
private Integer age;


 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>


5.2.3 dao层

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

public class UserDaoImpl implements UserDao {

//需要spring注入模板
private HibernateTemplate hibernateTemplate;
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}

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

}


5.2.4 service层

public class UserServiceImpl implements UserService {

private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@Override
public void register(User user) {
userDao.save(user);
}

}


5.2.5 hibernate.cfg.xml

<session-factory>
<!-- 1基本4项 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///ee19_spring_day03</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">1234</property>

<!-- 2 配置方言 -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

<!-- 3 sql语句 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>

<!-- 4 自动生成表(一般没用) -->
<property name="hibernate.hbm2ddl.auto">update</property>

<!-- 5本地线程绑定 -->
<property name="hibernate.current_session_context_class">thread</property>

<!-- 导入映射文件 -->
<mapping resource="com/itheima/domain/User.hbm.xml"/>

</session-factory>


5.2.6 applicationContext.xml

5.2.6.1 添加命名空间

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">[/code] 
5.2.6.2 加载hibernate配置文件

<!-- 1 加载hibenrate.cfg.xml 获得SessionFactory
* configLocation确定配置文件位置
-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
</bean>

<!-- 2创建模板
* 底层使用session,session 有sessionFactory获得
-->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>


5.2.6.3 dao和service

<!-- 3 dao -->
<bean id="userDao" class="com.itheima.dao.impl.UserDaoImpl">
<property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean>

<!-- 4 service -->
<bean id="userService" class="com.itheima.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>


5.2.6.4 事务管理

<!-- 5 事务管理 -->
<!-- 5.1 事务管理器 :HibernateTransactionManager -->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" >
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 5.2 事务详情 ,给ABC进行具体事务设置 -->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="register"/>
</tx:attributes>
</tx:advice>
<!-- 5.3 AOP编程,ABCD 筛选 ABC  -->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.itheima.service..*.*(..))"/>
</aop:config>


5.2.7 测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class TestApp {

@Autowired
private UserService userService;

@Test
public void demo01(){
User user = new User();
user.setUsername("jack");
user.setPassword("1234");
user.setAge(18);

userService.register(user);
}
}


5.3 spring整合hibernate:没有hibernate.cfg.xml 【掌握】

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

 修改dao层,继承HibernateDaoSupport

5.3.1 修改spring,配置SessionFactory

<!-- 1.1加载properties文件 -->
<!-- 1.2 配置数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql:///ee19_spring_day03"></property>
<property name="user" value="root"></property>
<property name="password" value="1234"></property>
</bean>

<!-- 1.3配置 LocalSessionFactoryBean,获得SessionFactory
* configLocation确定配置文件位置
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
1)dataSource 数据源
2)hibernateProperties hibernate其他配置项
3) 导入映射文件
mappingLocations ,确定映射文件位置,需要“classpath:” ,支持通配符
<property name="mappingLocations" value="classpath:com/itheima/domain/User.hbm.xml"></property>
<property name="mappingLocations" value="classpath:com/itheima/domain/*.hbm.xml"></property>
mappingResources ,加载执行映射文件,从src下开始 。不支持通配符*
<property name="mappingResources" value="com/itheima/domain/User.hbm.xml"></property>
mappingDirectoryLocations ,加载指定目录下的,所有配置文件
<property name="mappingDirectoryLocations" value="classpath:com/itheima/domain/"></property>
mappingJarLocations , 从jar包中获得映射文件
-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
</props>
</property>
<property name="mappingLocations" value="classpath:com/itheima/domain/*.hbm.xml"></property>
</bean>


5.3.2 修改dao,使用HibernateDaoSupport

 继承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);
}

}


 spring 删除模板,给dao注入SessionFactory

<!-- 3 dao -->
<bean id="userDao" class="com.itheima.dao.impl.UserDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>




5.4 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

5.4.1 action类

 通用

public class UserAction extends ActionSupport implements ModelDriven<User> {

//1 封装数据
private User user = new User();

@Override
public User getModel() {
return user;
}

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


 功能

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


5.4.2 spring配置

<!-- 6 配置action -->
<bean id="userAction" class="com.itheima.web.action.UserAction" scope="prototype">
<property name="userService" ref="userService"></property>
</bean>


5.4.3 struts配置

<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="{1}">
<result name="success">/messag.jsp</result>
</action>
</package>
</struts>


5.4.4 jsp表单

<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>


5.4.5 配置web.xml

<!-- 1 确定spring xml位置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.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>


5.5 struts整合spring:struts创建action 【】

 删除spring action配置

 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



struts-plugins.xml ,struts整合spring

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


struts的action将由spring创建

总结,之后action由spring创建,并按照名称自动注入

6 要求
