MybatiPlus 分頁插件PaginationInnerInterceptor

config類引入插件

//Spring boot方式
@Configuration
@MapperScan("com.baomidou.cloud.service.*.mapper*")
public class MybatisPlusConfig {
    //舊版
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        // 設置請求的頁面大於最大頁后操作， true調回到首頁，false 繼續請求  默認false
        // paginationInterceptor.setOverflow(false);
        // 設置最大單頁限制數量，默認 500 條，-1 不受限制
        // paginationInterceptor.setLimit(500);
        // 開啟 count 的 join 優化,只針對部分 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;
    }
}

使用測試

    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);
