Mybatis-plus的两种分页插件的配置方式

第一种：

package com.paic.ocss.gateway.admin.config;

import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

import com.baomidou.mybatisplus.entity.GlobalConfiguration;

/**
 * mybatis的配置类

 * @author zhangkai940
 * @date 2018-11-22
 */
@Configuration
@MapperScan({"com.paic.ocss.gateway.dao.mapper","com.paic.ocss.gateway.admin.mapper"})
@Import(value = { com.paic.ocss.monitor.cat.mybatis.SpringCloudCatMybatisConfig.class })
public class MybatisConfig {

    @Bean
    public GlobalConfiguration globalConfiguration() {
        GlobalConfiguration global = new GlobalConfiguration();
        global.setDbType("mysql");
        return global;
    }

    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor page = new PaginationInterceptor();
        page.setDialectType("mysql");
        return page;
    }

}

第二种：

package com.paic.ocss.gateway.dao.config;

import com.baomidou.mybatisplus.entity.GlobalConfiguration;
import com.github.pagehelper.PageHelper;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

import java.util.Properties;

@Configuration
@MapperScan("com.paic.ocss.gateway.dao.mapper*")
@Import(value = { com.paic.ocss.monitor.cat.mybatis.SpringCloudCatMybatisConfig.class })
public class MybatisConfig {

    @Bean
    public GlobalConfiguration globalConfiguration() {
        GlobalConfiguration global = new GlobalConfiguration();
        global.setDbType("mysql");
        return global;
    }

    /**
     * 配置mybatis的分页插件pageHelper
     * @return
     */
    @Bean
    public PageHelper pageHelper(){
        PageHelper pageHelper = new PageHelper();
        Properties properties = new Properties();
        properties.setProperty("offsetAsPageNum","true");
        properties.setProperty("rowBoundsWithCount","true");
        properties.setProperty("reasonable","true");
        //配置mysql数据库的方言
        properties.setProperty("dialect","mysql");
        pageHelper.setProperties(properties);
        return pageHelper;
    }

}
