Enabling lazy loading did not achieve the desired effect

[youngledo]

Using the example code of this project, I enabled lazy loading, but found that it still loaded when starting.

My understanding is that when lazy loading is enabled, the following code will not execute without being called:

Here is my simplified code based on the example:

package sample.mybatis.xml;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SampleXmlApplication {

  public static void main(String[] args) {
    SpringApplication springApplication = new SpringApplication(SampleXmlApplication.class);
    springApplication.run(args);
  }

}

Other code has not been actively triggered or called:

However, it seems to work when I use '@ MapperScan':

I seem to understand that the mybatis.configuration.lazy-loading-enabled is not used to control the lazy loading of Mapper, but to control the lazy loading of SQL scripts, right?

Hello @youngledo ,

Yes, in MyBatis, lazy loading means lazily executing nested SELECTs.
https://mybatis.org/mybatis-3/sqlmap-xml.html#nested-select-for-association

[youngledo]

OK, but I have a question, why does the configuration not provide lazy loading of Bean, but through "@ MapperScan?

mybatis.lazy-initialization=true is invalid.

[harawata]

• Lazy loading is a feature of MyBatis (we call it "the core").
• Lazy initialization is a feature of Spring.

These two are completely different and unrelated.
And @MapperScan is an annotation provided by MyBatis Spring.
