Java The following three annotation methods are supported ：

1、Java What are the types of comments —— Single-line comments

In double slashes “//” identification , Only one line can be annotated , It's used where there's little information to annotate . open Eclipse, stay Java Use single line comments in the code .

2、Java What are the types of comments —— Multiline comment

Included in “/*” and “*/” Between , Can annotate a lot of lines . For better readability , Generally, the first and last lines do not write comments ( It's also more beautiful ).

Be careful ： Multiple line comments can nest single line comments , But you can't nest multiline comments and document comments .

3、Java What are the types of comments —— Documentation Comments

Included in “/**” and “*/” Between , You can also annotate multiple lines of content , It is generally used in class 、 Methods and variables , To describe its function . After comment , The mouse over the class and variable will automatically display the content of our comments .

Be careful ： Document comments can nest single line comments , You cannot nest multiline comments and document comments , Generally, the first and last lines don't write comments .

The key is coming. and xml Comments cannot be used Only use

<!--  -->

 

  If you change to other comments, they will appear

resultMap Red explosion
