JAVA 8 method reference, java method referenceWhat is method reference?
Simply put, it is a Lambda expression. In Java 8, we use Lambda expressions to create anonymous methods, but sometimes Our Lambda expressions may only call an existing method without doing anything else.
, when the program executes, the main method first enters the bottom of the stack memory, then the code from the top down to execute the loading method, etc. will be stacked one by one, also known as compression stack.3. Heap memory , loading instantiated objects executed in the stack memory, or some reference data types will open up a space in the heap memory and generate a 16-based address to the reference name.Attached: The specific implementation will be in line with the specific procedures

I. Preface:
In the previous blog, we used jotm to implement distributed transactions. This article uses atomikos.
The basic code is the same, that is, the configuration is slightly different.

2. configuration file: ApplicationContext. xml
For other code, see the previous blog.
One common sense before Java 8 is that if you want to define an anonymous inner class in a method and use local variables (including parameters) within that method, you need to use the final keyword modification. There are many interpretations and explanations of this mechanism on the Internet, but most of them are an abstract understanding. If you can analyze the bytecode, the problem is clear.
