java - HQL 检查字段是否包含字符串列表中的任何字符串

Question

我如何编写 HQL 来检查字段是否包含字符串列表中的任何字符串。我试过这个:

StringBuffer queryString = new StringBuffer("from Property p where status is true");
    if(!searchDto.getLocationTokens().isEmpty()) {
        queryString.append(" and p.city in (:locationTokens) or p.state in (:locationTokens) or p.zipcode in (:locationTokens)");
        for(String locationToken : searchDto.getLocationTokens()) {
            queryString.append(" or p.address LIKE "+locationToken+"%");
        }
    }

Query query = sessionFactory.getCurrentSession().createQuery(queryString.toString());
    if(!searchDto.getLocationTokens().isEmpty())
        query.setParameterList("locationTokens", searchDto.getLocationTokens());

    List<Property> properties = query.list();

但它会抛出异常。

在上面的代码中，for-each 循环部分是造成问题的地方。

感谢任何帮助。

Answer 1

在 HQL 中，您不能将 % 与命名参数一起使用。

应该是，

for(int i = 0; i < searchDto.getLocationTokens().size(); i++ )  { 
    queryString.append(" or p.address LIKE :addressFilterToken" + i);
}

然后，您可以将值传递给命名参数，

for(int i = 0; i < searchDto.getLocationTokens().size(); i++ )  {
     query.setParameter("addressFilterToken" + i, 
                "%" + searchDto.getLocationTokens().get(i) + "%");
}
