3. ページングプラグインインターセプターの設定

package xiaoxu.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**

 */
@Configuration
public class MybatisPlusConfig {
    
    

        @Bean
        public MybatisPlusInterceptor    mybatisPlusInterceptor(){
    
    
            MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
            mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
            return mybatisPlusInterceptor;
        }
}
