    </build>

三、文字配置描述
1堡牡、Spring配置
SpringMVC是Spring家族的一部分抒抬，天然支持Spring，所以配置Spring一句話晤柄，配置一個監(jiān)聽器即可

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

2擦剑、SpringMVC配置
web.xml

   <!-- mvc配置文件，說明是位于resources目錄下的sprign-config.xml
      如果不通過這樣的配置芥颈，默認(rèn)是讀取WEB-INF目錄下的servlet名稱對應(yīng)的xml文件惠勒。
如：本例中DispatcherServlet的名稱定義為web，則需要讀取web-servlet.xml作為SpringMVC的配置文件
    --> 
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-config.xml</param-value>
    </context-param>
    <servlet>
        <servlet-name>web</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value></param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>web</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3爬坑、spring-config.xml配置

<!-- 加載屬性文件-->
<context:property-placeholder location="classpath:config.properties" />
 <!-- 加載其他配置文件纠屋，本項(xiàng)目將mvc和mybatis分為兩個文件配置，
   這種方式只是為了讓配置文件更加清晰-->
  <import resource="classpath:spring/spring-mvc.xml"/>
  <import resource="classpath:spring/spring-mybatis.xml"/>

4盾计、spring-mvc.xml 位于resources.spring目錄下

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


    <context:component-scan base-package="net.begincode"/>
    
    <!-- jackson解析解析對象到j(luò)son-->
    <bean id="objectMapper" class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
        <property name="indentOutput" value="false"/>
        <property name="simpleDateFormat" value="yyyy-MM-dd"/>
    </bean>
    <!-- 用jackson處理responseBody注解 -->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                <property name="objectMapper" ref="objectMapper"/>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

    <!-- 資源文件位置售担，jsp文件和favico.ico文件 -->
    <mvc:resources mapping="/" location="/WEB-INF/jsp/"/>
    <mvc:resources mapping="/favicon.ico" location="/"/>  

    <!-- jsp view支持 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

5赁遗、spring-mybatis.xml 位于resource.spring目錄下

<?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: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/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">
    <!-- 注解的事務(wù)支持 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
     <!-- 數(shù)據(jù)源采用阿里的druid數(shù)據(jù)源 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <!-- 基本屬性 url、user族铆、password -->
        <property name="url" value="${jdbc_url}" />
        <property name="username" value="${jdbc_user}" />
        <property name="password" value="${jdbc_password}" />
        <!-- 配置初始化大小岩四、最小、最大 -->
        <property name="initialSize" value="1" />
        <property name="minIdle" value="1" />
        <property name="maxActive" value="20" />

        <!-- 配置獲取連接等待超時的時間 -->
        <property name="maxWait" value="60000" />

        <!-- 配置間隔多久才進(jìn)行一次檢測骑素，檢測需要關(guān)閉的空閑連接炫乓，單位是毫秒 -->
        <property name="timeBetweenEvictionRunsMillis" value="60000" />

        <!-- 配置一個連接在池中最小生存的時間刚夺，單位是毫秒 -->
        <property name="minEvictableIdleTimeMillis" value="300000" />

        <property name="validationQuery" value="SELECT 'x'" />
        <property name="testWhileIdle" value="true" />
        <property name="testOnBorrow" value="false" />
        <property name="testOnReturn" value="false" />

        <!-- 打開PSCache献丑，并且指定每個連接上PSCache的大小 -->
        <property name="poolPreparedStatements" value="true" />
        <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />

        <!-- 配置監(jiān)控統(tǒng)計(jì)攔截的filters -->
        <property name="filters" value="stat" />
    </bean>

   
    <!-- 事務(wù)配置 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>


    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        <property name="configLocation" value="classpath:spring/mybatis.xml"/>
    </bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="net.begincode.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>


</beans>

6、mybatis.xml 上一個配置中用到了mybatis侠姑，需要對他進(jìn)行一些基礎(chǔ)參數(shù)的設(shè)置创橄，就在這文件中配置如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <settings>
        <!-- Globally enables or disables any caches configured in any mapper under this configuration -->
        <setting name="cacheEnabled" value="true"/>
        <!-- Sets the number of seconds the driver will wait for a response from the database -->
        <setting name="defaultStatementTimeout" value="3000"/>
        <!-- Enables automatic mapping from classic database column names A_COLUMN to camel case classic Java property names aColumn -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- Allows JDBC support for generated keys. A compatible driver is required.
        This setting forces generated keys to be used if set to true,
         as some drivers deny compatibility but still work -->
        <setting name="useGeneratedKeys" value="true"/>
    </settings>

</configuration>
