Druid是一个数据库连接池实现，用于提供高性能的数据库连接。Druid提供了合并数据库连接池、SQL监控、StatFilter插件等功能。

每次看到程序中报了这样的一大篇长幅的bug内容，是不是内心有一丢丢犯怵的赶脚！！哈哈，这些其实都不是太大的问题，关键是我们要抓住关键点，从这些一大堆的内容中找出关键点，那就是Caused by: org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'slaveDataSource'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial。

大致的意识是说：

由以下原因引起：org.springframework.jdbc.datasource.lockup。DataSourceLookupFailureException：无法查找名为“slaveDataSource”的JNDI数据源；嵌套异常是javax.naming。NoInitialContextException：需要在环境或系统属性中指定类名，或将其作为小程序参数，或在应用程序资源文件java.naming.factory.initial中指定类名

其实最开始我也是一头雾水，最后实在没有办法，进行了Debug模式调试，逐句代码排除，最后找到原因了

这个地方是由于我粗心写错了，应该将参数值 masterDataSource 传递进来。

看到了吗，控制台已经不在报刚才我们那些一大堆的bug内容了，耶！我们成功了！

后续项目启动过程中遇到的问题比较简单，没有再次粘贴代码，看下框架启动成功了！！！

若有不严谨的地方，欢迎各位IT界的大咖评判指正！！
