java - PostgreSQL 的 JPA 查询

Question

我有以下查询，该查询在通过 Postgres 运行时有效-

select * from my_schema.my_table where (jsonb_1 @> '"789"' or jsonb_2 @> '"789"') and (status != 'BAD_STATUS');

它检查 jsonb_1(字符串列表)中是否存在 "789" 值，例如:["456", "789"] 或 jsonb_2 中的 "789" (字符串列表)示例:["123", "456"] 并且状态不是 BAD_STATUS。我试图在 Spring Data JPA(版本 1.5.6.RELEASE)中表示相同的查询，并尝试了以下两个但出现异常。

查询1:

@Query(value = "select * from my_schema.my_table where (jsonb_1 @> :jsonbValue or jsonb_2 @> :jsonbValue) and (status != :badStatus)", nativeQuery = true)
List<MyEntity> findAllByJsonbValueAndStatusNot(@Param("jsonbValue") String jsonbValue, @Param("badStatus") String badStatus);

异常(exception):

查询2:

@Query(value = "select * from my_schema.my_table where (jsonb_1 @> ?1 or jsonb_2 @> ?1) and (status != ?2)", nativeQuery = true)
List<MyEntity> findAllByJsonbValueAndStatusNot(String jsonbValue, String badStatus);

Answer 1

似乎是一个类型转换问题。试试这个

@Query(value = "select * from my_schema.my_table where (jsonb_1 @> :jsonbValue\:\:jsonb or jsonb_2 @> :jsonbValue\:\:jsonb) and (status != :badStatus)", nativeQuery = true)

或替代语法

@Query(value = "select * from my_schema.my_table where (jsonb_1 @> cast(:jsonbValue as jsonb) or jsonb_2 @> cast(:jsonbValue as jsonb)) and (status != :badStatus)", nativeQuery = true)
