maven整合ssh

一.SSH框架整合过程回顾

1.导入jar包

2.搭建struts环境

• 创建action,创建struts.xml配置文件,配置action
• 配置struts2的过滤器

3.搭建hibernate环境

• 搭建实体类
• 配置实体类和数据库表映射关系
• 创建hibernate核心配置文件
  • 引入映射配置文件

4.搭建spring环境

• 创建spring核心配置文件
• 让spring配置文件在服务器启动时候加载
  • 配置监听器(web.xml)
    
  • 指定spring配置文件位置(web.xml)
    

5.struts2和spring整合

• 把action在spring配置(action多实例的)
  
• 在struts.xml中action标签class属性里面写bean的id值
  

6.spring和hibernate整合

• 把hibernate核心配置文件中数据库配置,在spring里面配置
  
• 把hibernate的sessionFactory在spring配置
  

7.在dao里面使用hibernateTemplate

            </plugin>
            
        </plugins>
    </build>

1.搭建struts2环境

• 创建struts2配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
    "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>

    <package name="default" extends="struts-default" namespace="/">
        
        </action>
    </package>

</struts>

• 在web.xml中配置struts2核心过滤器

  
   <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
  

2.搭建spring环境

• 创建spring配置文件

applicationContext.xml

<?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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
    

• 在web.xml中配置监听器

   <context-param>
    <param-name>contextConfigLocation</param-name>
    <!-- 这里如果bean.xml在包it.playmker下，那么就应该写为：it/playmaker/bean.xml -->
    <param-value>classpath:applicationContext.xml</param-value>
	</context-param>
  <!-- 配置Spring的监听器 默认加载WEB-INF/applicationContext.xml-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3.搭建hiberanate环境

• 创建hibernate核心配置文件
  hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- DTD是约束,可以在核心包里面找 -->
<!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>

			<!-- 输出底层sql语句 -->
			<property name="hibernate.show_sql">true</property>
			<!-- 输出底层格式化语句 -->
			<property name="hibernate.format_sql">true</property>
		       <!-- hibernate帮创建表 需要配置之后
		       update:如果已经有表 更新 如果没有 创建 -->
		        <property name="hibernate.hbm2ddl.auto">update</property>
			
			<!-- 配置数据库方言 
			     在mysql里面实现分页 关键字 limit,只能使用mysql
			   在oracle数据库 实现分页 rownum
			   让hibernate框架识别不同数据库的自己特有的语句 -->
			<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
			
          </session-factory>
</hibernate-configuration>

4.先struts跟spring框架整合

• 整合关键点:action对象创建,交给spring创建

(1)创建action类

CustomerAction.java

public class CustomerAction extends ActionSupport {


}

(2)将action对象配置到spring配置文件中

applicationContext.xml

<!-- 配置action对象 -->
	<bean id="customerAction" class="it.playmaker.action.CustomerAction" scope="prototype">
	          <property name="customerService" ref="customerService"></property>
	</bean>

(3)在struts.xml中在action节点中class属性配置为spring工厂中的action对象bean的id

struts.xml

<package name="default" extends="struts-default" namespace="/">
        <action name="customerAction_*" class="customerAction" method="{1}">
          
        </action>
    </package>

5.spring跟hibernate整合

• 整合关键点:数据源dataSource交给spring,sessionFactory对象创建交给spring创建,事务管理

(1).配置dataSource

applicationContext.xml

 <!-- 加载属性文件 -->
    <context:property-placeholder location="classpath:db.properties"/>
    
   <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
                 <!-- 注入属性值 -->
                   <property name="driverClass" value="${jdbc.driverClass}"></property>
                    <property name="jdbcUrl" value="${jdbc.url}"></property>
                     <property name="user" value="${jdbc.username}"></property>
                      <property name="password" value="${jdbc.password}"></property>
         </bean>

db.properties

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/javaweb
jdbc.username=root
jdbc.password=T471912619

(2).配置sessionFactory

applicationContext.xml

  <!-- 配置Hibernate的SessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 注入连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置Hibernate属性 -->
          <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
    </bean>

(3).事务管理

• 配置事务管理器:PlatFormTransactionManager:接口
• jdbc:DataSourceTransactionManager
• Hibernate:HibernateTransactionManager

 <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
	    <property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	
	<!-- xml管理事务 -->
     <tx:advice id="txAdvice">
            <tx:attributes>
                <!-- 匹配业务类中方法名 -->
                 <tx:method name="save*"/>
                  <tx:method name="update*"/>
                   <tx:method name="delete*"/>
                    <tx:method name="find*" read-only="true"/>
                    <tx:method name="*"/>
            </tx:attributes>     
     </tx:advice>
     
     <!-- 配置aop -->
     <aop:config>
        <!-- 配置切点:具体哪些方法要增强(真正被增强的方法) -->
        <aop:pointcut expression="execution(* it.playmaker.service.*.*(..))" id="cut"/>
         <!-- 配置切面:将增强逻辑作用到切点(通知+切入点)-->
         <aop:advisor advice-ref="txAdvice" pointcut-ref="cut"/>
     </aop:config>
     
     <!-- 1.开启注解驱动 2.在service类或者方法上使用注解@Transactional-->
     <tx:annotation-driven transaction-manager="transactionManager" />

6.测试

(1).在地址栏输入action请求http://localhost:8080/ssh01/customerAction_findOne.action

• action-service-dao 完成客户查询

(2).具体实现

• 创建客户实体类,映射文件,将映射文件引入hibernate核心配置

Customer.java

public class Customer {
         private String custId;
         private String custName;
         private String address;
		
		public String getCustId() {
			return custId;
		}
		public void setCustId(String custId) {
			this.custId = custId;
		}
		public String getCustName() {
			return custName;
		}
		public void setCustName(String custName) {
			this.custName = custName;
		}
		public String getAddress() {
			return address;
		}
		public void setAddress(String address) {
			this.address = address;
		}
         
}

Customer.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 引入Hibernate映射文件约束 -->
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

    <!-- class指定POJO类和数据库表之间的对应 -->
    <class name="it.playmaker.domain.Customer" table="t_customer" >

       <!-- id指定数据库中表的主键,以及主键生成策略 -->
       <id name="custId" type="java.lang.String" >
       <column name="id" length="32"></column>
           <generator class="uuid" />
       </id>

       <!-- property指定表字段和POJO中的属性的对应 -->
       <property name="custName" column="custName" type="java.lang.String">
       </property>

       <property name="address" column="address" type="java.lang.String">
       </property>

    </class>

</hibernate-mapping>

hibernate.cfg.xml

			<!-- 第三部分:把映射文件放到核心配置文件中 必须的 -->
            <mapping resource="it/playmaker/domain/Customer.hbm.xml"/>

• 创建action,service,dao 并且完成注入,并在类添加属性生成set方法

public class CustomerAction extends ActionSupport {

	private CustomerService customerService;

	private String custId;
	
	public void setCustomerService(CustomerService customerService) {
		this.customerService = customerService;
	}
	
   public void setCustId(String custId) {
		this.custId = custId;
	}
  

public String findOne() throws Exception{
	   Customer customer =customerService.findOne(custId);
	   ActionContext.getContext().getValueStack().push(customer);//存入值栈中
	   
	   return SUCCESS;
   }
}

public interface CustomerService {

	Customer findOne(String custId);

}

public class CustomerServiceImpl implements CustomerService {
           private CustomerDao customerDao;

		public void setCustomerDao(CustomerDao customerDao) {
			this.customerDao = customerDao;
		}

		@Override
		public Customer findOne(String custId) {
			
			return customerDao.findOne(custId);
		}
         
}

public interface CustomerDao {

	Customer findOne(String custId);





}

public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {

	public Customer findOne(String custId) {
		
		return this.getHibernateTemplate().get(Customer.class,custId);
	}

}

• 在spring配置文件完成注入

applicationContext

     <!-- 先注入dao -->
     <bean id="customerDao" class="it.playmaker.dao.impl.CustomerDaoImpl">
              <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>
     
     <!-- 再注入service -->
     <bean id="customerService" class="it.playmaker.service.impl.CustomerServiceImpl">
             <property name="customerDao" ref="customerDao"></property>
     </bean>
    <!-- 配置action对象 -->
	<bean id="customerAction" class="it.playmaker.action.CustomerAction" scope="prototype">
	          <property name="customerService" ref="customerService"></property>
	</bean>

• 在struts.xml中配置action

<package name="default" extends="struts-default" namespace="/">
        <action name="customerAction_*" class="customerAction" method="{1}">
            <result name="success">/index.jsp</result>
          <allowed-methods>findOne</allowed-methods> <!--在struts2高版本不写这行,即使通配符匹配到方法也无法访问,一直报错-->
        </action>
    </package>

<%@ 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">
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
        <s:property value="custName"/>
</body>
</html>

访问http://localhost:8080/maven_ssh/customerAction_findOne.action?custId=1

成功！！！！！！！

三.总结

• 页面提交参数,服务端action接收参数-参
• 调用业务层方法->dao方法->DB-调
• 将返回的数据存入值栈-存
• 配置结果视-转
