二、pom.xml
创建maven工程,加入如下配置到pom.xml中

<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</configuration>
</plugin>

</project>

三、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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/jdbc
http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
">
<import resource="applicationContext-tx.xml"></import>
<!-- Enable the use of matrix variables -->
<mvc:annotation-driven enable-matrix-variables="true">
<!--mvc:async-support task-executor="" default-timeout=""> 异步执行的配置
<mvc:callable-interceptors>
<bean></bean>
</mvc:callable-interceptors>
<mvc:deferred-result-interceptors>
<bean></bean>
</mvc:deferred-result-interceptors>
</mvc:async-support-->
</mvc:annotation-driven>
<!-- 启动注解 -->
<context:annotation-config></context:annotation-config>
<!-- 配置自动扫描根目录 -->
<context:component-scan base-package="lxy.study">
<!-- 这个是表示要排除掉扫描annotation注解的所有Controller -->
<!--ontext:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" /-->
</context:component-scan>
<!-- mvc中提供了默认的servlet来处理静态资源,即当所有的mapping都匹配不上的时候,
最后匹配到SimpleUrlHandlerMapping,这里主要是用于ModelAndView转发的时候,处理html/CSS等资源用 -->
<mvc:default-servlet-handler/>
</beans>

四、配置dataSource

<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/jdbc
http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
">
<import resource="applicationContext-dataSource.xml"></import>
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置自动事务管理 -->
<tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

 

五、配置事务管理

<?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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:jdbc="http://www.springframework.org/schema/jdbc"
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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/jdbc
http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
">
<import resource="applicationContext-dataSource.xml"></import>
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置自动事务管理 -->
<tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

 

六、mybatis-config的配置

<?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>
<!-- 定义Mybatis的运行时行为 -->
<settings>
<!-- 自动映射配置:
NONE:取消自动映射
PARTIAL:对对象本身进行映射,不对嵌套进行映射,默认值
FULL:对嵌套进行映射
-->
<setting name="autoMappingBehavior" value="PARTIAL"/>
<!-- 开启延迟加载,默认是false -->
<setting name="lazyLoadingEnabled" value="true"/>
<!-- 默认的延迟加载是:层级延迟加载,如果开启aggressiveLazyLoading,
则会完全使用延迟加载,需要什么加载什么,默认为false -->
<setting name="aggressiveLazyLoading" value="true"/>
</settings>
<typeHandlers>
<!-- 同样可以通过配置包路径,扫描指定包下面的所有handler类 -->
<package name="com.lxy.study.core.typehandlers"/>
</typeHandlers>
<plugins>
<plugin interceptor="lxy.study.core.plugins.PagePlugin">
<property name="dialect" value="mysql"></property>
<property name="pageSqlId" value=".*ByPage"></property>
</plugin>
</plugins>
<!-- mapper映射器的引入包含多种方法
1. 通过mapper的resource属性导入xml的mapping配置文件 (推荐使用)
2. 通过mapper的class属性导入java类型的Interface接口
3. 通过mapper的url属性导入xml的mapping配置文件
4. 通过package标签,配置扫描的包路径,使mybatis自动装载包下面的所有mapper对象(@Mapper标注的)
需要注意的是,这里的方式可以混合使用,但是,同一个mapper不能在多种不同的方式中被包含,不然会有异常抛出 -->
<mappers>
<mapper resource="mappings/CountryMapping.xml"/>
</mappers>
</configuration>
