See the pagehelper - spring - boot, use rise very convenient, for more PageHelper can click https: / / github com/pagehelper/Mybatis - PageHelper.
When spring boot is integrated with mybatis and needs to be paginated, we first add maven support
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>5.1.2</version>
</dependency>
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-autoconfigure</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper-spring-boot-starter</artifactId>
<version>1.2.3</version>
</dependency>
Approach 1: We add application. yml(yml that spring needs to read)
pagehelper:
helperDialect: mysql
reasonable: true
supportMethodsArguments: true
params: count=countSql
Then restart it.
The configuration file is eventually read by java and injected into spring bean, so our method 2 is to configure its bean class, which is easy to modify by hot loading. Of course, method 1 is easier.
Option 2: Create a new PageHeleperConfig under the annotations covering package
import com.github.pagehelper.PageHelper;
import java.util.Properties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**

*/
@Configuration
public class PageHelperConfig {
@Bean
public PageHelper getPageHelper(){
PageHelper pageHelper=new PageHelper();
Properties properties=new Properties();
properties.setProperty("helperDialect","mysql");
properties.setProperty("reasonable","true");
properties.setProperty("supportMethodsArguments","true");
properties.setProperty("params","count=countSql");
pageHelper.setProperties(properties);
return pageHelper;
}
}
Basic knowledge of pageHelper is:
import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;
Page<T> tPage= PageHelper.startPage(page,limit);
The next sentence of the query to page. You only need to use List < T > receive
