我使用Spring 4.0.5和MyBatis 3.2.7与maven。我在WEB-INF/myBatis文件夹下有我的myBatis-config.xml文件。在尝试创建sqlSessionFactory bean时,我得到了FileNotFoundError。
这是我的豆子:
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="myBatis/myBatis-config.xml" />
<property name="mapperLocations" value="classpath*:com/attinad/mappers/*.xml" />
</bean>

我试过把/classpath*:WEB-INF/myBatis/myBatis-config.xml作为值。但它没有帮助。
请帮助我找到解决方案,因为我花了几个小时调试这个
请找到myBatis-config.xml文件。
<?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="cacheEnabled" value="true" />
<setting name="lazyLoadingEnabled" value="true" />
<setting name="multipleResultSetsEnabled" value="true" />
<setting name="useColumnLabel" value="true" />
<setting name="useGeneratedKeys" value="false" />
<setting name="defaultExecutorType" value="SIMPLE" />
<setting name="defaultStatementTimeout" value="100" />
<setting name="safeRowBoundsEnabled" value="false" />
<setting name="mapUnderscoreToCamelCase" value="false" />
<setting name="localCacheScope" value="SESSION" />
<setting name="jdbcTypeForNull" value="OTHER" />
<setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString" />
</settings>
<typeAliases><typeAlias type="classpath*:com.attinad.model.Employee" alias="Emp"/></typeAliases>
</configuration>
我的Mapper文件EmployeeMapper.xml文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.attinad.dao.EmployeeMapperInterface">
<select id="getEmployeeWithId" parameterType="Long" resultType="Emp">
select * from
employees where
id=#{empId}
</select>
</mapper>
你有两个选择。
-
将
myBatis-config.xml
放在WEB-INF/classes
文件夹中,并输入classpath:myBatis-config.xml
-
由于您正在使用maven
src/main/resources
已经在classpath
中,因此您可以将文件放在src/main/resources
下并使用classpath:myBatis-config.xml
我的配置是:
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="WEB-INFmybatisConf.xml" />
</bean>
和
<bean id="sqlMapClient" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg ref="sqlSessionFactory" />
</bean>
