背景
自从mybatis-plus某版本3.4/3.5更新之后，原先的分页插件paginationInterceptor无法正常使用，这里给出最新的solution。

paginationInterceptor 变更为 paginationInnerInterceptor

验证

旧版配置

import com.baomidou.mybatisplus.extension.plugins.pagination.optimize.JsqlParserCountOptimize;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;

@EnableTransactionManagement
@Configuration
@MapperScan("com.egag.cert.mapper")
public class MybatisPlusConfig {
	  /**
     * 分页插件(old) 
     * @authorzhengkai.blog.csdn.net
     */
      @Bean
      public PaginationInterceptor paginationInterceptor() {
          PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
          // 设置请求的页面大于最大页后操作， true调回到首页，false 继续请求  默认false
          // paginationInterceptor.setOverflow(false);
          // 设置最大单页限制数量，默认 500 条，-1 不受限制
          paginationInterceptor.setLimit(1000);
          // 开启 count 的 join 优化,只针对部分 left join
          paginationInterceptor.setCountSqlParser(new JsqlParserCountOptimize(true));
          return paginationInterceptor;
      }
}

新版java配置

package com.software.dev.config;


import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import java.util.Collections;

@EnableTransactionManagement
@Configuration
@MapperScan("com.software.dev.mapper")
public class MybatisPlusConfig {
    /**
     * 分页插件 3.5.X
     * @author zhengkai.blog.csdn.net
     */
    @Bean
    public PaginationInnerInterceptor paginationInnerInterceptor() {
        PaginationInnerInterceptor paginationInterceptor = new PaginationInnerInterceptor();
        // 设置最大单页限制数量，默认 500 条，-1 不受限制
        paginationInterceptor.setMaxLimit(-1L);
        paginationInterceptor.setDbType(DbType.MYSQL);
        // 开启 count 的 join 优化,只针对部分 left join
        paginationInterceptor.setOptimizeJoin(true);
        return paginationInterceptor;
    }
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
        mybatisPlusInterceptor.setInterceptors(Collections.singletonList(paginationInnerInterceptor()));
        return mybatisPlusInterceptor;
    }
}
