SSH整合

 

SSH环境整合

 

版本与环境

Spring      版本：spring-framework-4.3.4.RELEASE

Hibernate 版本：hibernate-release-5.2.4.Final

Struts2     版本：struts-2.3.34

Mysql       版本：Mysql 8.0

Tomcat     版本：apache-tomcat-7.0.88

导入Jar包：下载Jar包 小贴士：左侧下载链接内的Jar全部导入即可，如要添加功能，视况而定。

具体框架具体功能在实践中自然而然的就领悟到了，无须学习框架没有任何基础前死记硬背，先把流程打通，再具体分析，事半功倍。

web.xml

web.xml具体内容简单明了讲解一下：

1      <context-param>
2         <param-name>contextConfigLocation</param-name>
3         <param-value>
4                     classpath*:applicationContext.xml
5         </param-value>
6     </context-param>
7     <listener>
8         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
9     </listener>

这是加载Spring配置文件的监听器，web服务一开启容器开始创建加载。classpath*:applicationContext.xml 配置文件路径

 1       <filter>
 2         <filter-name>openSession</filter-name>
 3         <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
 4         <init-param>
 5             <param-name>sessionFactoryBean</param-name>
 6             <param-value>sessionFactory</param-value>
 7         </init-param>
 8         <init-param>
 9             <param-name>singleSession</param-name>
10             <param-value>true</param-value>
11         </init-param>
12         <init-param>
13             <param-name>flushMode</param-name>
14             <param-value>AUTO</param-value>
15         </init-param>        
16     </filter>
OpenSessionInViewFilter过滤器：控制session的创建与销毁，涉及懒加载等知识点，与此类相似的还有OpenSessionInViewInterceptor.class(从名字可以看出是加在拦截器上的)，具体用法Google或者Baidu吧。
1       <listener>
2         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
3     </listener>
IntrospectorCleanupListener监听器：管理内存的对象，回收没用的垃圾对象，大概此意。
1     <filter-mapping>
2         <filter-name>openSession</filter-name>
3         <url-pattern>/*</url-pattern>
4     </filter-mapping>
5   
6     <filter-mapping>
7         <filter-name>struts2</filter-name>
8         <url-pattern>/*</url-pattern>
9     </filter-mapping>

这个就很简单了，不做解释了。注意：struts2的过滤器要放在openSession下面！否则，自己体验一下，你就知道了。

  • 配置applicationContext.xml(记得放在src下,与web.xml配置的一致即可，免得计算机没读取到文件，你气的把电脑砸了)

95     </bean>
96 </beans>
applicationContext.xml

也是简单的讲解一下：

 1     <context:property-placeholder
 2         location="classpath:jdbc.properties" />
 3     <bean id="dataSource"
 4         class="com.mchange.v2.c3p0.ComboPooledDataSource">
 5         <property name="driverClass" value="${driverClass}"></property>
 6         <property name="jdbcUrl" value="${jdbcUrl}"></property>
 7         <property name="user" value="${user}"></property>
 8         <property name="password" value="${password}"></property>
 9         <property name="initialPoolSize" value="${initialPoolSize}"></property>
10         <property name="minPoolSize" value="${minPoolSize}"></property>
11         <property name="maxPoolSize" value="${maxPoolSize}"></property>
12     </bean>
location="classpath:jdbc.properties" 这是引用的外部属性文件，不要着急马上给你贴代码.
这是配置一个连接池的bean，用的是c3p0，你也可以用其他的，看你喜欢。
    <!-- 配置session工厂 -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <!-- 需要去了解学习 -->
                <prop key="javax.persistence.validation.mode">none</prop>
            </props>
        </property>
        <property name="mappingLocations">
            <value>classpath:/com/zhangpn/entity/Book.hbm.xml</value>
        </property>
    </bean>
classpath:/com/zhangpn/entity/Book.hbm.xml这里是hibernate映射文件，先从基础的XML配置方式入门，再学习注解，会学习的更加扎实吧，个人观点。
其他的不想介绍了，先粘贴上，把代码保证正确，运行通了，再捣鼓原理。
driverClass=com.mysql.cj.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/zhangpn?serverTimezone\=GMT&useSSL\=false
user=root
password=zhangpn
initialPoolSize=5
minPoolSize=5
maxPoolSize=10

放在src下，也不一定总之，要与你的配置相一致，还记得location="classpath:jdbc.properties这句话吗？在上面的配置里！找不到复制粘贴搜索一下，你就懂喽！

23         </action>
24     </package>
25 
26 </struts>
struts.xml

里面的代码相信你是理解的，先别急着修改，先复制粘贴

 

接下来就是写代码了，先别写先把结构弄出来：

按照这个结构建立包和文件

 

 接下来就是见证奇迹的时刻了，运行部署！

输入信息
