- 分析原因
单纯代码测试中 这个问题不会出现 一旦部署到容器中 就会抛出上面的异常
因为 在 web.xml文件中 我们要在应用启动就加载 spring的配置文件 所以会在web.xml中 配置相关信息如下
<!--应用启动就加载配置文件-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring_cfg.xml</param-value>
</context-param>
这样 可以在加载时 就读取spring的配置文件 当读到 dataSource.properties时 我们很容易在spring中的配置文件中 进行如下的错误配置
<!--加载数据源配置文件 此处要解决路径问题 避免部署时出现问题-->
<context:property-placeholder location="dataSource.properties"/>
这时 io无法正确加载 dataSource.properties 归根到底就是路径问题
所以 如法炮制 在 dataSource.properties 前也加上 classpath*:
正确的方式为：
<!--加载数据源配置文件 此处要解决路径问题 避免部署时出现问题-->
<context:property-placeholder location="classpath:dataSource.properties"/>
