给人的第一印象是Mapper层和Service层和controller之间的bean都没有被Spring容器管理起来。
但是排除之后发现是
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<property name="dataSource" ref="dataSource"/>
<property name="mapperLocations">
<array>
<value>classpath:com/watermelon/web/mapper/DictMapper.xml</value>
</array>
</property>
<property name="typeAliasesPackage" value="com.watermelon.web.model"/>
</bean>
上面那行mybatis-config.xml加入后错误。
最后发现是mybatis-config.xml配置错误。
<?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="logImpl" value="LOG4J"/>
<setting name="cacheEnabled" value="true"/>
<setting name="mapUnderscoreToCamelCase" value="true"/>
<setting name="aggressiveLazyLoading" value="false"/>
</settings> </configuration>
