    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) 抛出空指针异常，如何处理？

输出：

Caused by: java.lang.NullPointerException

谢谢！

将您的灵活搜索查询从

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

至

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

您应该发送DHProductLookupModel.PK搜索结果。

在您的情况下，您可以使用灵活搜索服务的getModelsByExample而不是编写查询。

你的方法会像

 public List<DHProductLookupModel> findProductbyCCsapProductId(final String code)
 {
     DHProductLookupModel dhProductLookupModel = new DHProductLookupModel();
     dhProductLookupModel.setSapProductID(code);
     return getFlexibleSearchService().getModelsByExample(dhProductLookupModel);
 }

在这里找到示例

感谢大家！我发现了问题。那是在我的春天。我只需要放：

 <context:component-scan base-package="myPackage"/>

为了安全起见，我还使用 DHProductLookupModel.PK 更改了查询。现在它的工作！
