Two 、 Text

          And the specific call , In fact, it is in this sentence that . The purpose is to generate the corresponding file according to the table name you enter . Is terby's humanized convenience easy to use .

strategy.setInclude(scanner(" Table name , Multiple English comma splits ").split(","));

        So I hope my friends who have used it , Can you give me some support , Easy to use things should be analyzed for everyone It's right to be happy together .

        Then comes the experiment , Is it useful , It depends on me to perform it and show you . I'll add a new one here sys_questions Take table as an example .

        I run it directly MyGenerator Medium main The main function . Then input sys_questions Back carriage return . You can see , The following screenshots , Those files have been generated directly .

          If you don't believe it, you can check it under the corresponding folder , I won't show you screenshots here , After all, the content output of the console after execution is obvious . I have told you the corresponding generated file and its location . In fact, it has been proved to be generated .

        There is another thing , Although it is generated , In fact, some automatically generated file codes need to be manually modified , It's not perfect , There's a flaw , But you can also not change , I am one of those people with typical obsessive-compulsive disorder , So I will change this to my code style .

         For example, the generated entity class , The native one is created for us in this format by default . This is definitely not what we want , It is also an irresponsible way of writing , We need not only to modify @ApiModel Of value And describtion All have to be modified so that developers can understand it at a glance .

         Because this is the mapping of the corresponding database field table , So the best name is , First of all , Can you consider what this table is for , Second, bring the entity name , that will do .

         such as ：value = Problem feedback information entity .description=" Tracking user problem feedback information entity ", In this way, you know what you mean , One can know at a glance that this watch is dry , It is also conducive to subsequent maintenance personnel to understand or rewrite .

         Secondly , That is, the primitive entity class does not have @TableName Annotated , We'd better add , Specify the mapping database table name . such as ： This is how I specify it here .

@TableName("user_questions")

Screenshot of database table ：

          So you just add the corresponding table name you need to map to the annotation . Everyone should understand this , There is no need for me to introduce the detailed use of this annotation ？

 ... ...

        All right. , The above is all about this issue , Have you learned to give up ？ If it helps you , Please don't forget to give bug bacteria [ Three companies support ] yo .
