ssh基本整合(配置版本）

本篇文章，和大家分享一下如何使用ssh框架做基本的整合（配置式）

1.首先第一步我们需要部分jar包，我这里用的是idea工具，所以只需要引入对应的pom节点。

96             <version>11.2.0.1.0</version>
97         </dependency>

所需maven节点

2.配置web.xml文件，既然叫ssh整合，那么spring的配置和struts2的配置也就必不可少了。

首先是spring配置，我们需要配置两点：

<!--Spring配置
    1.上下文  识别applicationContext.xml
    2.监听器 在Tomcat容器启动的时候，帮我创建Spring容器，并且放入application中
-->

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

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

然后是struts2的配置

<!--Struts2配置  核心过滤器 -->
  <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

注意：因为配置文件规定的顺序，所以spring的 listener配置要配置在struts2的filter后面。

3.接下来我们关注实体层

我这里以部门类为例

  private Integer deptno;        
  private String deptname;
  //set，get方法省略

然后配置其hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="cn.ssh.entity">
    <class name="Dept" table="Dept" schema="y2166">
        <id name="deptno" column="DEPTNO">
            <generator class="native"></generator>
        </id>
        <property name="deptname" column="DEPTNAME"></property>
    </class>
</hibernate-mapping>

4.DAO层比较简单两个文件

IDeptDAO

public interface IDeptDAO {
    public int addDept(Dept dept);
}

DeptDAOImpl

public class DeptDAOImpl implements IDeptDAO {
    SessionFactory sessionFactory;
    //set，get方法省略
   public int addDept(Dept dept) {
        Session session = sessionFactory.getCurrentSession();
        Serializable count = session.save(dept);
        return (Integer)count;
    }
}

5.service层

IDeptService

public interface IDeptService {
    public int addDept(Dept dept);
}

DeptServiceImpl

   private IDeptDAO dao;
   //set，get方法省略
   @Transactional
   public int addDept(Dept dept) {
        return dao.addDept(dept);
   }

6.action层

  public class DeptAction implements Action{
    private Dept dept;
    //set，get方法省略    
    private IDeptService service;
    //set，get方法省略    
    public String execute() throws Exception {
        service.addDept(dept);
        return SUCCESS;
    }
  }

7.配置文件

首先jdbc.properties文件，此文件专门用于配置连接数据库的属性

jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.username=y2166
jdbc.password=y2166

然后就是最主要的applicationContext.xml文件

此文件内容较多

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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.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
">
    <!--1.数据源  c3p0-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="driverClass" value="${jdbc.driverClassName}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--2.识别到jdbc.properties-->
    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

    <!--3.形成SessionFactory-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="hibernateProperties">
            <props>
                <!--方言-->
                <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
                <!--是否打印sql-->
                <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">org.springframework.orm.hibernate5.SpringSessionContext</prop>
            </props>
        </property>
        <!--关联小配置-->
        <property name="mappingDirectoryLocations" value="classpath:cn/ssh/entity"></property>
    </bean>

    <!--4.dao-->
    <bean id="deptDao" class="cn.ssh.dao.DeptDAOImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <!--5.service-->
    <bean id="deptService" class="cn.ssh.service.DeptServiceImpl">
        <property name="dao" ref="deptDao"></property>
    </bean>

    <!--6.action-->
    <bean id="deptAction" class="cn.ssh.action.DeptAction">
        <property name="service" ref="deptService"></property>
    </bean>

    <!--7.事务管理器-->
    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

    <!--8.事务真实配置-->
    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

以及最后的struts2文件

<?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>
   <!--修改这个文件的时候，可以自动重新部署-->
    <constant name="struts.devMode" value="true" />
    <package name="default" namespace="/" extends="struts-default">
        <action name="add" class="deptAction">
            <result>/jsp/index.jsp</result>
        </action>
    </package>
</struts>

8.jsp界面

<form method="post" action="/add">
      部门名称： <input name="dept.deptname"/>
       <input type="submit" value="添加"/>
</form>

9.最终效果

点击添加后

数据库

以上就是使用ssh简单的使用
