  • Reproducibility: always

Reproducing the bug

Description

When there is a lot of commodity data in the database, this problem will appear in multi thread search of commodities

Code

threadExecutors.execute(new Runnable() { @Override public void run() { /** **/ list = SqliteProductManager.getInstance().findProducts(ALL_PRODUCT_TYPE, queryText); } catch (Exception e) { e.printStackTrace(); } } });

`public List findProducts(ProductQueryParams queryParams){
long startTime = System.currentTimeMillis();
QueryBuilder query = productModelBox.query();

    boolean isSearch = queryParams.seachText != null && queryParams.seachText.length() > 0;
    if(isSearch){
        String seachText = queryParams.seachText.toUpperCase();
        long longVal = -1;
        try {
            longVal = Long.parseLong(seachText);
        } catch (Exception e) {
            longVal = -1;
        }
        query.contains(ProductModel_.goodsNameFullEn,seachText)
                .or().contains(ProductModel_.goodsNameEn,seachText)
                .or().contains(ProductModel_.goodsDesc,seachText)

        ;
        if(longVal  > 0 ){
            query.or().startsWith(ProductModel_.barCode,seachText);
            query.or().equal(ProductModel_.goodsId,longVal);
        }else{
            query.or().contains(ProductModel_.barCode,seachText);
        }

    }
    List<ProductModel> list = new ArrayList<>();
    String txt = "商品搜索 ";
    try {
        list = query.order(ProductModel_.goodsSn).build().find();
    }catch (Exception e){
        e.printStackTrace();
        txt += " 异常 ："+e.getMessage();
    }finally {
        XLog.i(txt+"  Thread name  : "+Thread.currentThread().getName());
    }

    return list;
