ClassLoader.getSystemClassLoader().getResourceAsStream("jdbc.properties"); Times null pointer exception
tags: tomcat
When connecting to the database, I reported this 500, thinking that there was a problem with the server deployment, and then the java code soon created a new Test test connection database. I found that the line ClassLoader.getSystemClassLoader().getResourceAsStream("jdbc.properties") in jdbcUtils reported an error.
The solution is to change this line toFileInputStream inStream=new FileInputStream("druid.properties"); Just remember to put the configuration file under the project
