org.springframework.beans.factory.BeanDefinitionStoreException异常

1、下面是我遇到的异常信息:

2017-03-25 18:01:11,322 [localhost-startStop-1][org.springframework.web.context.ContextLoader]-
[ERROR] Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException:
Invalid bean definition with name 'dataSource' defined in file
[C:\Users\Aaron\workspace\HT\target\classes\spring\applicationContext.xml]:
Could not resolve placeholder 'jdbc.driver' in string value "${jdbc.driver}";
nested exception is java.lang.IllegalArgumentException:
Could not resolve placeholder 'jdbc.driver' in string value "${jdbc.driver}"

2、查找错误

2.1 在 applicationContext.xml 里有如下配置:

  <bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource">
    <property name="driverClassName" value="${jdbc.driver}"/>

2.2 在 db-mysql.properties 里有如下配置:

  jdbc.driverClassName=com.mysql.jdbc.Driver,这里本应该配置为“jdbc.driver",但却配置成了”jdbc.driverClassName“

3、解决办法

  修改db-mysql.properties文件如下:

  jdbc.driver=com.mysql.jdbc.Driver
