A picture will give you a thorough understanding of how spring solves circular dependency!!

In the high concurrency scenario, the author has developed it , Simple to offer 、 Stable 、 Extensible delayed message queuing framework , It has precise timing task and delay queue processing function . Since the open source for more than half a year , It has successfully provided precise timing scheduling scheme for more than ten small and medium-sized enterprises , It has withstood the test of production environment . In order to benefit more children's shoes , Now give the open source framework address :

PS: Welcome to Star Source code , It's fine too pr Your blazing code .

Write it at the front

lately , Looking at Spring Source code , notice Spring When solving the source code of the circular dependency problem , Have to say , The source code is too bad . image Spring This top-level project source code , There is this kind of xxx Code for . After watching it several times, I nodded big , I believe many friends will feel the same way as me . What shall I do? ? Or step down the heart , Slowly gnaw the source code . Final , I will Spring How to solve the source code of circular dependency is summarized in the following flow chart , such , According to the flow chart, it is much clearer to read the source code !!

The illustration Spring Cyclic dependence

Spring The source code for solving the problem of circular dependency is really bad , It's just a meal if + else Nested operations for . For the time being, I still don't give the source code to my friends . I will Spring The source code for solving the circular dependency problem is summarized in the following flowchart , It looks much clearer , Combined with the flow chart Spring Source code , Yield twice the result with half the effort .

Not much said , Upper figure :

To tell the truth , see Spring Source code , summary , drawing . It took me nearly 3 Hours . Let's take a look at this picture Spring Source code , I believe it will not let you down . If it helps you , Please give me a compliment 、 Let's watch and forward .

Okay , That's all for today , I'm glacier , See you next time ~~
