  • IntelliJ IDEA 2017版 spring-boot2.0.2 搭建 JPA springboot DataSource JPA sort排序方法使用方式, 添加关联表的 order by

    1、sort可以直接添加在命名格式的字段中

    1 List<BomMain> findAllByDeleted(Integer deleted, Sort sort);
    View Code

    2、可以作为pageable的一个参数使用

    1 Page<Originals> selectBomSeriesList(Pageable pageable);
    View Code

    向sort传参的方式

    1、装入Pageable使用

    1 Sort sort = new Sort(Sort.Direction.ASC, "serieName");
    2 
    3         Pageable pageable = PageRequest.of(0, 10, sort);
    4 
    5         Page<Originals> list = bomSeriesRepository.selectBomSeriesList(pageable);
    6 
    7         System.out.println(list.getTotalPages());
    View Code

    2、自行使用

    1 Sort sort = new Sort(Sort.Direction.ASC, "sequence");
    2 
    3         List<BomMain> bomMainList = bomMainRepository.findAllByDeleted(1, sort);
    4 
    5         log.info("列表" + gson.toJson(bomMainList));
    View Code

    3、多个条件表关联使用

     1   List<Sort.Order> listOrder = new ArrayList<>();
     2 
     3         listOrder.add(new Sort.Order(Sort.Direction.ASC, "bomMain.sequence"));
     4 
     5         listOrder.add(new Sort.Order(Sort.Direction.ASC, "sequence"));
     6 
     7         Sort sort = Sort.by(listOrder);
     8 
     9         List<BomSub> bomSubList = bomSubRepository.findAllByDeletedAndBomMainMainId(1, "1", sort);
    10 
    11         log.info("列表" + gson.toJson(bomSubList));
    View Code

    生成SQL

     1 SELECT
     2     bomsub0_.subId AS subId1_9_,
     3     bomsub0_.mainId AS mainId8_9_,
     4     bomsub0_.deleted AS deleted2_9_,
     5     bomsub0_.engName AS engName3_9_,
     6     bomsub0_.fullName AS fullName4_9_,
     7     bomsub0_.isOnShelf AS isOnShel5_9_,
     8     bomsub0_.sequence AS sequence6_9_,
     9     bomsub0_.subName AS subName7_9_ 
    10 FROM
    11     bomsub bomsub0_
    12     LEFT OUTER JOIN bommain bommain1_ ON bomsub0_.mainId = bommain1_.mainId 
    13 WHERE
    14     bomsub0_.deleted =? 
    15     AND bommain1_.mainId =? 
    16 ORDER BY
    17     bommain1_.sequence ASC,
    18     bomsub0_.sequence ASC
