In general Java projects and now particularly hot data analysis projects, the use of database and database resource pool connection is a commonplace. Today it's a simple way to sort through the process: We look at the code in order of dispatch: Comment, we are from the spark data analysis to do demo expansion: First, suppose that the read-write

We know that there is a well-known design pattern for shared resources: resource pools (resource pool). This model is to solve the problem caused by the frequent allocation of resources ﹑ release. To solve the above problems, the
