1.Mybatis

1.1、dp.properties

資料庫資訊

db.url=jdbc:mysql://localhost:3306/smbms?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
db.driver=com.mysql.cj.jdbc.Driver
db.user=root
db.pwd=123123

1.2、mybatis.xml(mybatis核心配置檔案)

<?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">
<!--configration核心配置檔案-->
<configuration>
<!--引入外部檔案-->
  <properties resource="db.properties"/>
<!--配置Pojo別名-->
  <settings>
    <!--標準的日誌工廠實現-->
    <setting name="logImpl" value="STDOUT_LOGGING"/>
    <!--是否開啟駝峰命名規則（camel case）對映-->
    <setting name="mapUnderscoreToCamelCase" value="true"/>
    <!--顯式地開啟全域性快取-->
    <setting name="cacheEnabled" value="true"/>
  </settings>
  <typeAliases>
    <package name="com.sy.pojo"/>
  </typeAliases>
<!--可以配置多個環境，初學階段一個環境即可-->
  <environments default="development">
    <environment id="development">
      <transactionManager type="JDBC"/>
      <dataSource type="POOLED">
        <property name="driver" value="${db.driver}"/>
        <property name="url" value="${db.url}"/>
        <property name="username" value="${db.user}"/>
        <property name="password" value="${db.pwd}"/>
      </dataSource>
    </environment>
  </environments>
  <mappers>
    <mapper class="com.sy.dao.user.UserMapper"/>
  </mappers>
</configuration>
​
 

1.3、mapper.xml(介面類Mapper)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--configration核心配置檔案-->
<mapper namespace="com.sy.dao.user.UserMapper">
​
​
</mapper>

2.Spring

2.1、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:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    https://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/aop
    https://www.springframework.org/schema/aop/spring-aop.xsd">
  <import resource="spring-dao.xml"/>
​
​
  <bean id="userMapper" class="com.sy.mapper.UserMapperImpl">
    <property name="sqlSession" ref="sqlSession"/>
  </bean>
</beans>
 

2.2、spring-dao.xml(spring整合mybatis)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    https://www.springframework.org/schema/beans/spring-beans.xsd">
​
  <!--DataSource:使用spring的資料來源替換Mybatis的配置檔案
    直接使用Spring提供的JDBC
  -->
  <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/smbms?useUnicode=true&amp;characterEncoding=utf8&amp;serverTimezone=GMT%2B8&amp;useSSL=false"/>
    <property name="username" value="root"/>
    <property name="password" value="123123"/>
  </bean>
​
  <!--sqlSessionFactory-->
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="datasource"/>
    <!--繫結Mybatis配置檔案-->
    <property name="configLocation" value="classpath:mybatis-config.xml"/>
    <!--     <property name="mapperLocations" value="classpath:com/sy/mapper/*.xml"/>-->
  </bean>
  <!--相當於mybatis的sqlsession-->
  <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <!--只能使用構造器注入sqlSessionFactory，因為沒有set方法-->
    <constructor-arg index="0" ref="sqlSessionFactory"/>
  </bean>
​
</beans>

2.3、帶事務管理的spring-dao.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:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    https://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/tx
    https://www.springframework.org/schema/tx/spring-tx.xsd
    http://www.springframework.org/schema/aop
    https://www.springframework.org/schema/aop/spring-aop.xsd">
​
  <!--DataSource:使用spring的資料來源替換Mybatis的配置檔案
    直接使用Spring提供的JDBC
  -->
  <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/smbms?useUnicode=true&amp;characterEncoding=utf8&amp;serverTimezone=GMT%2B8&amp;useSSL=false"/>
    <property name="username" value="root"/>
    <property name="password" value="123123"/>
  </bean>
​
  <!--sqlSessionFactory-->
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="datasource"/>
    <!--繫結Mybatis配置檔案-->
    <property name="configLocation" value="classpath:mybatis-config.xml"/>
    <!--     <property name="mapperLocations" value="classpath:com/sy/mapper/*.xml"/>-->
  </bean>
  <!--相當於mybatis的sqlsession-->
  <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <!--只能使用構造器注入sqlSessionFactory，因為沒有set方法-->
    <constructor-arg index="0" ref="sqlSessionFactory"/>
  </bean>
​
  <!--配置宣告式事務-->
  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="datasource"/>
  </bean>
  <!--結合AOP實現事務的織入-->
  <!--配置事務通知-->
  <tx:advice id="txAdvice" transaction-manager="transactionManager">
    <!--給哪些方法配置事務-->
    <!--配置事務的傳播特性：new propagation-->
    <tx:attributes>
      <tx:method name="*" propagation="REQUIRED"/>
    </tx:attributes>
  </tx:advice>
  <!--配置事務的切入-->
  <aop:config>
    <aop:pointcut id="txPoint" expression="execution(* com.sy.mapper.*.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
  </aop:config>
</beans>

2.3、spring自動裝配

<?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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    https://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    https://www.springframework.org/schema/context/spring-context.xsd">
​
  <context:annotation-config/>
​
</beans>

3.其他配置

3.1、log4j.properties

log4j.rootLogger=debug, stdout, R
​
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
​
log4j.appender.stdout.layout.ConversionPattern=-%p-%d{yyyy/MM/dd HH:mm:ss,SSS}-%L-%m%n
​
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=./log/sy.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
​
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=-%p-%d{yyyy/MM/dd HH:mm:ss,SSS}-%L-%m%n
​
log4j.logger.com.codefutures=DEBUG

3.2、解決Maven靜態資源過濾問題

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

3.3、解決使用Maven專案時發行版本不支援的問題

<properties>
    <!-- 專案編碼 -->
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <!-- 本地編譯JDK版本 -->
    <maven.compiler.source>14</maven.compiler.source>
    <!-- 專案部署JDK版本 -->
    <maven.compiler.target>14</maven.compiler.target>
</properties>
