搜索(查询)抛出NullPointerException [英] search(query) throws NullPointerException

问题描述

    public List<DHProductLookupModel> findProductbyCCsapProductId(final String code)
{
    final String queryString = "SELECT {p:" + DHProductLookupModel.SAPPRODUCTID + "}" + "FROM{" + DHProductLookupModel._TYPECODE
            + " AS p}" + "WHERE" + "{p:" + DHProductLookupModel.SAPPRODUCTID + "}=?code ";
    final FlexibleSearchQuery query = new FlexibleSearchQuery(queryString);
    query.addQueryParameter("code", code);
    return flexibleSearchService.<DHProductLookupModel> search(query).getResult();
}

search(query)抛出Null Pointer Exception，如何处理呢?

search(query) throws Null Pointer Exception, how to handle this?

输出:

Caused by: java.lang.NullPointerException
    at de.hybris.platform.servicelayer.search.impl.DefaultFlexibleSearchService.getJaloResult(DefaultFlexibleSearchService.java:396) ~[coreserver.jar:?]

    at com.cancom.core.productlookup.service.impl.CCProductLookupServiceImpl.getProductforCCmanufacturerProductId(CCProductLookupServiceImpl.java:37) ~[classes/:?]

谢谢！

推荐答案

从

 final String queryString = "SELECT {p:" + DHProductLookupModel.SAPPRODUCTID + "}" + "FROM{" + DHProductLookupModel._TYPECODE
        + " AS p}" + "WHERE" + "{p:" + DHProductLookupModel.SAPPRODUCTID + "}=?code ";

到

 final String queryString = "SELECT {p:" + DHProductLookupModel.PK + "}" + "FROM{" + DHProductLookupModel._TYPECODE
        + " AS p}" + "WHERE" + "{p:" + DHProductLookupModel.SAPPRODUCTID + "}=?code ";

您应该在搜索结果中发送DHProductLookupModel.PK.

You should send DHProductLookupModel.PK in search result.
