MybatiPlus 分页插件PaginationInnerInterceptor

config类引入插件

//Spring boot方式
@Configuration
@MapperScan("com.baomidou.cloud.service.*.mapper*")
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();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}

使用测试

    PageResult<ContactMember> pageResult = new PageResult<>();
    long current = param.getCurrent() == null ? 1 : param.getCurrent();
    long size = param.getSize() == null ? 10 : param.getSize();
 
    Page<ContactMember> page = new Page<>(current, size);
    IPage<ContactMember> contactMemberIPage = contactMemberMapper.selectPage(page, param);
