When writing to use Java, there will inevitably be some template code to write, otherwise get/set,tostring, hashcode, close resources, define constructors and so on. The code will look very redundant and very long. Lombok project can be we get rid of these things, through a series of annotations, Lombok can help us to automatically generate these functions.Lombok website Address: https://projectlombok.org/R
