idea中spring boot项目，使用MyBatisPlus分页配置导致# SQL: SELECT id,username,password FROM user LIMIT ? LIMIT ?

1、错误出现的Java文件：mybatis-plus配置类

/**
 * https://mp.baomidou.com/guide/page.html
 * MyBatisPlus分页插件配置类
 */
@Configuration
public class MybatisPlusConfig {
    
    
    // 旧版
    /*@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(500);
        // 开启 count 的 join 优化,只针对部分 left join
        paginationInterceptor.setCountSqlParser(new JsqlParserCountOptimize(true));
        return paginationInterceptor;
    }*/

    // 最新版
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
    
    
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
//        ### SQL: SELECT  id,username,password  FROM user LIMIT ? LIMIT ?
//        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.H2));
        PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();
        paginationInnerInterceptor.setOverflow(true);
        //修改后的一条语句
        paginationInnerInterceptor.setDbType(DbType.MYSQL);
        interceptor.addInnerInterceptor(paginationInnerInterceptor);
        return interceptor;
    }
}

2、错误原因：DbType.H2换成DbType.MYSQL

因为我用的数据库是MySQL，而我最开始配置（官网cv）为H2了，就导致SQL语句解析错误

@Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
    
    
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
//        ### SQL: SELECT  id,username,password  FROM user LIMIT ? LIMIT ?
//        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.H2));
        PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor();
        paginationInnerInterceptor.setOverflow(true);
        //修改后的一条语句
        paginationInnerInterceptor.setDbType(DbType.MYSQL);
        interceptor.addInnerInterceptor(paginationInnerInterceptor);
        return interceptor;
    }

3、解决办法

见第二点，修改相关DbType
