mybatis-plus分页查询

做分页查询要有两步：
第一步，设置MyBatisPlus配置类

package com.gsoft.demo.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.*;

/**
 * MyBatisPlus配置类
 * @author Administrator
 */
@Configuration
public class MyBatisPlusConfig {

    /**
     * MyBatisPlus拦截器（用于分页）
     */
    @Bean
    public MybatisPlusInterceptor paginationInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        //添加MySQL的分页拦截器
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.SQLITE));
        return interceptor;
    }
}

第二步：在service层里进行分页

    @Override
    public Page getListByPage(int current, int size) {
        Page<SwaggerEntity> entityPage = new Page<>(current, size);
        QueryWrapper<SwaggerEntity> wrapper = new QueryWrapper<>();
        Page<SwaggerEntity> swaggerEntityPage = swaggerMapper.selectPage(entityPage, wrapper);
        return swaggerEntityPage;
    }
