  </dependencies>

二、建立三層架構目錄

在main目錄下建立java和resources目錄

三層架構存放在java目錄下

  • Controller

  • Service

  • Mapper

resources目錄存放配置及xml

  • application.xml

  • jdbcConfig.properties

  • log4j.properties

  • springmvc.xml

mapper的xml（編寫sql使用）

2.1. 編寫web.xml

在webapp目錄（沒有自行建立）下建立web.xml，配置攔截器

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
<!-- 配置Spring的監聽器 預設只加載WEB-INF下的applicationContext.xml檔案  -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
<!-- 設定配置檔案的路徑 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
<!-- 配置前端控制器  -->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--  載入配置檔案  -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
<!--  伺服器啟動時建立   -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
<!-- 設定字串編碼 -->
  <filter>
    <filter-name>characterEncodingFilter</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>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

三、編寫配置類

  • application.xml

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

<!--  開啟註解掃描 只掃描spring和mybatis  -->
    <context:component-scan base-package="com.hopu" >
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

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

<!--    spring 整合 mybatis-->
<!-- 1.配置連線池 C3P0 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>
<!--  2.配置SqlSessionFactory工廠  -->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--   注入資料來源     -->
         <property name="dataSource" ref="dataSource" />
<!--    實體類起別名    -->
        <property name="typeAliasesPackage" value="com.hopu.domain"></property>
<!--   指定mapper介面所對應的xml-->
        <property name="mapperLocations" value="classpath:com/hopu/mapper"></property>

    </bean>
<!--    3.配置介面AccountDao所在的包 對映掃描配置類 mvc配置 -->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--    介面所在的包    -->
        <property name="basePackage" value="com.hopu.mapper" />
<!--    掃描工廠並注入sqlSessionFactoryBeanName   -->
        <property name="sqlSessionFactoryBeanName" value="sessionFactory" />
    </bean>
<!-- 配置spring宣告式事務管理   -->
    <!--  配置事務管理器  -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--  傳入連線池物件      -->
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!--  配置事務通知  -->
    <tx:advice id="txadvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="ins*" />
            <tx:method name="up*" />
            <tx:method name="del*" />
            <!--  只讀的事務    -->
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <!-- 配置AOP增強   -->
    <aop:config>
        <aop:pointcut id="mypoint" expression="execution(* com.hopu.service.impl.*.*(..))"/>
        <aop:advisor advice-ref="txadvice" pointcut-ref="mypoint"></aop:advisor>
    </aop:config>
</beans>

3.1. 編寫jdbc.properties

1、oracle資料庫

jdbc.driver = oracle.jdbc.driver.OracleDriver
jdbc.url = jdbc:oracle:thin:@localhost:1521:XE/oracle
jdbc.username = wk123
jdbc.password = 123456

2、Mysql資料庫

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
jdbc.username = root
jdbc.password = 123

四、編寫mvc配置

<?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:mvc="http://www.springframework.org/schema/mvc"
       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/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!--  開始註解掃描，只掃描COntroller  -->
    <context:component-scan base-package="com.hopu">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

<!-- 配置檢視解析器   -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>


<!--  不攔截的靜態資源  -->
    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:resources mapping="/image/**" location="/image/" />
    <mvc:resources mapping="/css/**" location="/css/" />
    <mvc:resources mapping="/pages/**" location="/pages/" />
    <mvc:resources mapping="/jsp/**" location="/jsp/" />
    <mvc:resources mapping="/layui/**" location="/layui/" />

<!--  支援mvc註解  -->
    <mvc:annotation-driven  />

</beans>

五、編寫log4j

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory= CONSOLE ,    Debug,  LOGFILE,    info   warn error fatal
log4j.rootCategory=INFO,CONSOLE,

log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# RollingFileAppender 代表檔案 ConsoleAppender 代表控制檯
#日誌輸出到控制檯
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
#%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n 輸出內容 (%F:%L) 具體哪一行
log4j.appender.CONSOLE.layout.ConversionPattern=%-5p [%d{yyyy-MM-dd HH:mm:ss}] [%15.15t] ===> %m  (%F:%L) \n

#日誌輸出到檔案
#log4j.appender.LOGFILE=org.apache.log4j.FileAppender
#log4j.appender.LOGFILE.Encoding=UTF-8
#log4j.appender.LOGFILE.File=E:/A/log4j.log
#log4j.appender.LOGFILE.Append=true
#log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
#log4j.appender.LOGFILE.layout.ConversionPattern=%-5p [%d{yyyy-MM-dd HH:mm:ss}] [%15.15t] ===> %m

六、建立mapper的xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- mapper類名 -->
<mapper namespace="com.hopu.mapper.IAccount">

<!--  配置引用 減少重複程式碼 id=方法名  -->
    <sql id="findall">
        select * from account
    </sql>
<!-- 查詢所有 resultType=返回的引數型別 -->
    <select id="findAll" resultType="account"  >
        <include refid="findall"></include>
    </select>
<!-- 新增賬戶 parameterType=接受的類名 -->
    <insert id="SaveAccount" parameterType="account"  >
        insert into account(name,money) values (#{name},#{money})
    </insert>

</mapper>
