Handlebar series

Preface

In the use of FindBugs When , Found applicable Idea Of FindBugs Already in 2016 Maintenance was stopped in , No longer compatible IDEA2020,

So we have this issue , Contains how to install spotBugs, And how to use spotBugs.

---

Tips ： The following is the main body of this article

One 、SpotBugs What is it? ？

website ：SpotBugs Is a use of static analysis to find Java Wrong tool in code ,SpotBugs need JRE（ or JDK）1.8.0 Or later to run . however , It can be analyzed from 1.0 To 1.9 Any of the Java Version compiled program .

Static analysis ： Check Java Bytecode （.class file ） Is there a mistake .

Two 、SpotBugs The download

1. Online installation （ The three step ）

Click on install install

2. Website download

Landing official website （ The official website will automatically match the corresponding version , The premise is to start idea）

Extraction code ：9xwt
use Install Plugin from Disk Install local package , And then restart .

3、 ... and 、 Use SpotBugs

Common configuration SpotBugS

spotbugs It mainly includes 10 Categories: bug
1.Bad practice（90 More than ） Bad practice , Violate common sense or necessary code conventions , Like rewriting equals But I didn't rewrite it hashcode.
2.Correctness （150 More than ） The code here may cause errors at run time , Not in line with expectations , For example, null pointer error .
3.Experimental（9 Kind of ）spotbugs Not applicable here , Probably the matching pattern doesn't apply here .
