maven搭建spring mvc+spring jdbc項目

上一篇說了maven創建web項目，接下來學習框架配置，由於之前用過SSH，spring mvc+hibernate，相比較來說，個人感覺SSH太過笨重，struts2可能不會退出歷史，但是肯定越來越多的程序猿更喜歡更輕量級的spring mvc。而hibernate作爲單表操作時候優勢大大滴，而多表操作的時候就略顯蛋疼了，雖然也支持sql查詢，還是覺得不如直接用jdbc算了，看項目需要選擇吧，此例子採用spring jdbc，以前沒用過，作爲學習，記錄一下。

框架就是各種蛋疼的配置文件一起堆吧，不多說，上文件。

1、項目結構圖

2、web.xml

<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>Archetype Created Web Application</display-name>

  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>
  <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:*applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!-- 編碼轉換器 -->
  <filter>
    <filter-name>setCharacter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>setCharacter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

3、applicationCotext.xml

這裏只是最基本的配置，根據需求可能有些更復雜的配置，以後用到再問度娘就可以。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:property-placeholder location="classpath:jdbc.properties" />

    <!-- 掃描類包，將標註Spring註解的類自動轉化Bean，同時完成Bean的注入 -->
    <context:component-scan base-package="com.mos" />
    <!--<context:component-scan base-package="com.mos.action" />

    <!-- 啓動Spring MVC的註解功能，完成請求和註解POJO的映射 -->
    <mvc:annotation-driven />

    <!-- 配置數據源 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
        <property name="driverClass" value="${jdbc.driverClassName}"></property>

        <!--初始化時獲取的連接數，取值應在minPoolSize與maxPoolSize之間。Default: 3 -->
        <property name="initialPoolSize" value="10"></property>
        <!--最大空閒時間,60秒內未使用則連接被丟棄。若爲0則永不丟棄。Default: 0 -->
        <property name="maxIdleTime" value="60"></property>
        <!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。Default: 3 -->
        <property name="acquireIncrement" value="5"></property>

        <property name="maxStatements" value="0"></property>
        <!--每60秒檢查所有連接池中的空閒連接。Default: 0 -->
        <property name="idleConnectionTestPeriod" value="60"></property>
        <!--定義在從數據庫獲取新連接失敗後重復嘗試的次數。Default: 30 -->
        <property name="acquireRetryAttempts" value="30"></property>
        <!--獲取連接失敗將會引起所有等待連接池來獲取連接的線程拋出異常。但是數據源仍有效 保留，並在下次調用getConnection()的時候繼續嘗試獲取連接。如果設爲true，那麼在嘗試

        <property name="breakAfterAcquireFailure" value="true"></property>
        <!--因性能消耗大請只在需要的時候使用它。如果設爲true那麼在每個connection提交的 時候都將校驗其有效性。建議使用idleConnectionTestPeriod或automaticTestTable

        <property name="testConnectionOnCheckout" value="false"></property>
    </bean>

    <!-- 配置Jdbc模板 -->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <bean id="sQLPageHandle" class="com.mos.base.sql.MysqlSQLPageHandleImpl" />

    <!-- 定義事務管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 使用cglib代理，不再使用接口方式 -->
    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

    <!-- 配置視圖解析器，將ModelAndView及字符串解析爲具體的頁面 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:viewClass="org.springframework.web.servlet.view.JstlView"
          p:prefix="/WEB-INF/view/"
          p:suffix=".jsp" />

</beans>

4、jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mos
jdbc.username=root
jdbc.password=root

5、最重要的pom

此處spring用的4.1.2，和spring3裏面的jdbcTemplate會有差別，3裏面的一些方法已經廢棄了（下一篇會說BaseDao）
