Mybatis generator overwrites the XML file

Mybatis generator is generated by append by default. Therefore, if you want to regenerate the code, delete the original file first.

Solution:

1: create a custom patch class.

Overwritexmlplugin. Java

Package COM. my. common. generator; import Java. util. list; import Org. mybatis. generator. API. generatedxmlfile; import Org. mybatis. generator. API. introspectedtable; import Org. mybatis. generator. API. pluginadapter;/*** @ author wulm * @ date 7:39:45 on May 25 * @ version 1.0.0 */public class overwritexmlplugin extends pluginadapter {@ override public Boolean sqlmapgenerated (generatedxmlfile sqlmap, introspectedtable extends) {sqlmap. setmergeable (false); return Super. sqlmapgenerated (sqlmap, introspectedtable) ;}@ override public Boolean validate (list <string> warnings) {return true ;}}

View code

Note: The principle is to rewrite the sqlmapgenerated method. Set sqlmap. setmergeable (false );. Ismergeable is true by default, so it is set to false here.

 

2: add

<! -- Overwrite the XML file -->
<Plugin
Type = "com. My. Common. generator. myplugins. overwritexmlplugin"/>

 

When you execute the statement again, the original XML will be overwritten.

 

 

In addition, if you want to override the original Java file, it is recommended to use Java code to generate code, please refer to the official website: http://mbg.cndocs.ml/running/runningWithJava.html (use xml configuration file to run mbg from Java), the code inside the settings

Boolean overwrite = true;
