搭建SpringMVC+MyBatis开发框架四

在src/main下面新建一个resouces文件夹，我们继续配置一些资源

1.新增applicationContext.xml：



<?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:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.0.xsd
        http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd 
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd 
        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd">

    <description>Spring公共配置</description>
    
    <!-- 开启定时任务 -->
    <task:annotation-driven/>

    <!-- MyBatis配置 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 显式指定Mapper文件位置 -->
        <property name="mapperLocations" value="classpath*:/mybatis/*Mapper.xml" />
        <!-- mybatis配置文件路径 -->
        <property name="configLocation" value="classpath:/mybatis/config.xml"/>    
    </bean>
    
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
       <constructor-arg index="0" ref="sqlSessionFactory" />
       <!-- 这个执行器会批量执行更新语句, 还有SIMPLE 和 REUSE -->
       <constructor-arg index="1" value="BATCH" />
    </bean>

    <!-- 扫描basePackage接口 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 映射器接口文件的包路径， -->
        <property name="basePackage" value="net.quickcodes.dao" />
    </bean>

    <!-- 使用annotation定义事务 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />

    <!-- 数据源配置, 使用Tomcat JDBC连接池 -->
    <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
        <!-- Connection Info -->
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />

        <!-- Connection Pooling Info -->
        <property name="maxActive" value="${jdbc.pool.maxActive}" />
        <property name="maxIdle" value="${jdbc.pool.maxIdle}" />
        <property name="minIdle" value="0" />
        <property name="defaultAutoCommit" value="false" />
    </bean>

    <!-- production环境 -->
    <beans profile="production">
        <context:property-placeholder ignore-unresolvable="true" file-encoding="utf-8" 
        location="classpath:config.properties,classpath:jdbc.properties" />
    </beans>

</beans>

2.新增jdbc.properties,这个文件用来配置Mysql数据库的jdbc连接信息：

在resouces文件夹上有鼠标右键选择“New”>"Other":



选择"Properties File",点击"Next"按钮：



文件名输入jdbc.properties:



输入如下配置内容，这是连接MySQL数据库的url，用户名和密码，请根据你自己的实际情况配置值：



jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://127.0.0.1:3306/lesson-1?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&allowMultiQueries=true
jdbc.username=root
jdbc.password=123456

#connection pool settings
# maxIdle是最大的空闲连接数，这里取值为20，表示即使没有数据库连接时依然可以保持20个空闲的连接，它们不会被清除，随时处于待命状态
jdbc.pool.maxIdle=20
# maxActive是最大激活连接数，这里取值为190，表示同时最多有190个数据库连接
jdbc.pool.maxActive=190

3.同样方法新建一个config.properties文件，这个配置文件暂时不配置内容，以后有用途。

4.新增一个logback.xml配置文件：



<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

   <!-- 时间滚动输出 level为 DEBUG 日志 -->
    <appender name="file-debug" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>DEBUG</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY </onMismatch>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>/export/data/logs/debug.%d{yyyy-MM-dd}.log</FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
 
    <!-- 时间滚动输出 level为 INFO 日志 -->
    <appender name="file-info" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY </onMismatch>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>/export/data/logs/info.%d{yyyy-MM-dd}.log</FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    
    <!-- 时间滚动输出 level为 INFO 日志 -->
    <appender name="file-error" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY </onMismatch>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>/export/data/logs/error.%d{yyyy-MM-dd}.log</FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    
    <!-- 很多人使用Mybatis的时候，控制台不能输出SQL语句，造成调试困难。只需要让DAO层的日志级别调整为DEBUG就可以了 -->
    <logger name="net.quickcodes.dao" level="DEBUG" />

    <!-- 指定项目可输出的最低级别日志 -->
    <root level="INFO">
        <appender-ref ref="console" />
        <appender-ref ref="file-debug" />
        <appender-ref ref="file-info" />
        <appender-ref ref="file-error" />
    </root>
</configuration>

5.在resources文件夹下建立一个mybatis的文件夹，添加一个config.xml:

<?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>
        <setting name="cacheEnabled" value="true" />
    </settings>

</configuration>
