發(fā)布時(shí)間：2020-11-06 16:53:59 來(lái)源：億速云 閱讀：162 作者：Leah 欄目：開(kāi)發(fā)技術(shù)

使用MyBatis如何實(shí)現(xiàn)整合SpringMVC？針對(duì)這個(gè)問(wèn)題，這篇文章詳細(xì)介紹了相對(duì)應(yīng)的分析和解答，希望可以幫助更多想解決這個(gè)問(wèn)題的小伙伴找到更簡(jiǎn)單易行的方法。

1、添加spring相關(guān)jar包

2、配置ehcache jar包。

3、添加ehcache mybatis 適配器jar包（在mybatis官網(wǎng)）

4、添加spring mybatis 適配器jar包（在mybatis）官網(wǎng)

5、pom.xml

6、applicationContext.xml

  <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

</beans>

7、mybatis-config.xml

<&#63;xml version="1.0" encoding="UTF-8" &#63;>
<!DOCTYPE configuration
 PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
  <settings>
    <setting name="mapUnderscoreToCamelCase" value="true" />
    <setting name="jdbcTypeForNull" value="NULL" />

    <!--顯式的指定每個(gè)我們需要更改的配置的值，即使他是默認(rèn)的。防止版本更新帶來(lái)的問(wèn)題 -->
    <setting name="cacheEnabled" value="true" />
    <setting name="lazyLoadingEnabled" value="true" />
    <setting name="aggressiveLazyLoading" value="false" />
  </settings>

  <databaseIdProvider type="DB_VENDOR">
    <property name="MySQL" value="mysql" />
    <property name="Oracle" value="oracle" />
    <property name="SQL Server" value="sqlserver" />
  </databaseIdProvider>

</configuration>

注意：此處mybatis配置文件中沒(méi)有配置數(shù)據(jù)源，數(shù)據(jù)源由spring負(fù)責(zé)。

此外還需要ehcache.xml配置文件,Mapper.xml文件。
