mybatis延迟加载

配置完成后可能会报错Cannot enable lazy loading because CGLIB is not available. Add CGLIB to your classpath

是由于缺少jar包   cglig-2.2.jar  asm-2.2.3.jar

 

配置过程

mybatis-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>

<!-- 懒加载配置lazyLoadingEnabled：true使用延迟加载，false禁用延迟加载。默认为true
aggressiveLazyLoading：true启用时，当延迟加载开启时访问对象中一个懒对象属性时，将完全加载这个对象的所有懒对象属性-->

<setting name="lazyLoadingEnabled" value="true"/>
<setting name="aggressiveLazyLoading" value="false"/>
</settings>
</configuration>

 

spring-mybatis.xml

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/jbt/mapper/*.xml"></property>
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>

配置完成
