Java Postgres中JSONB列的JPA查询

java hibernate postgresql jpa

Java Postgres中JSONB列的JPA查询,java,hibernate,postgresql,jpa,Java,Hibernate,Postgresql,Jpa,我正在尝试使用JPA为Postgres DB中的JSONB列创建一个查询。查询将非常类似于以下示例： 其中jdoc是表api中的JSONB列 到目前为止，执行这个查询很容易，也不是问题。然而，如果我试图参数化查询，我就卡住了 以下是我尝试过的几个问题： 1） 这不起作用，因为？在以下符号之间无法识别： String name= "Magnafone"; JPA.em().createNativeQuery("SELECT jdoc FROM api WHERE jdoc @> '{\"n

我正在尝试使用JPA为Postgres DB中的JSONB列创建一个查询。查询将非常类似于以下示例：

其中
jdoc
是表
api
中的JSONB列

到目前为止，执行这个查询很容易，也不是问题。然而，如果我试图参数化查询，我就卡住了

以下是我尝试过的几个问题：

1） 这不起作用，因为？在以下符号之间无法识别：

String name= "Magnafone";

JPA.em().createNativeQuery("SELECT jdoc FROM api
WHERE jdoc @> '{\"name\": ?}'", Record.class)
.setParameter(1, name)

我尝试过其他一些方法，这些方法让Postgres或JPA以某种方式呕吐，但在使用JPA的参数化时，没有成功获取JSON参数

仅供参考：这很有效（别担心，我没有使用它）：

另外：我正在使用
createNativeQuery
，因为JPA无法识别
@>
-运算符

谢谢

pozs将答案作为评论发布：

尝试“…WHERE jdoc@>cast（“{\”company\”：“| | | | to_json（cast（？as text））| | | |}”as json）”（或者在最后一次cast时使用jsonb，如果合适的话）

尝试
| |
方法，但它应该类似于
“{\'company\”：\“'| |？| \'\”}
。当然，使用
setParameter（1，company）
。也不起作用：/他抱怨“-符号。如果我尝试
“{\'company\”：'| |？|}“
错误表示输入字符串意外结束。如果您在每个尝试的选项下的问题中添加实际的错误消息（如果有完整的堆栈跟踪），这将非常有用。顺便说一句，在上面的任何示例中，您似乎都没有使用“”关闭字符串。这是您尝试的实际代码吗？抱歉，复制粘贴错误。我会修好的。不是我正在使用的代码。我将很快发布准确的错误消息。请尝试
“…WHERE jdoc@>cast（“{\”company\”：“| | | to_json（cast（？as text））| |}as json）”
（或
jsonb
在最后一次cast时，如果合适的话）。
