Question

我遇到了这个问题，在网上搜索了2天后，你才是我最后的希望：p

我使用JPA条件api构建我的查询。一切正常，除非我想在混音中添加一些sql函数。

这是我用sql函数做的事情： Expression makePoint = criteriaBuilder.function("ST_MakePoint", Geometry.class, criteriaBuilder.parameter(double.class, "lat"), criteriaBuilder.parameter(double.class, "lng")); Expression distanceSphere = criteriaBuilder.function("ST_Distance_Sphere", double.class, place.get("coordinates"), makePoint); expression = criteriaBuilder.and(expression, criteriaBuilder.lessThanOrEqualTo(distanceSphere, radius)); criteriaQuery.select(root).where(expression);

声明工作正常，但是当我设置参数时： session.createQuery(criteriaQuery).setParameter("lat",lat)

我有这个错误：

我甚至尝试使用以下参数设置参数： double lat = 12.56; double lat = Double.parseDouble("12.552");

什么都没有用:(

Answer 1

从

更改类型

criteriaBuilder.parameter（ double.class ，“lat”），

到

criteriaBuilder.parameter（ Double.class ，“lat”），

应该适合你。进一步阅读refer。同时运行以下示例以了解您看到的异常。

    SELECT
      * 
    FROM 
      tblRules t1 
    LEFT JOIN 
      t1.vcTableName t2 
    ON 
      t1.biTableID=t2.biTestID 
    WHERE 
      t1.biRuleID=1;

具有双参数的JPA Criteria api函数
