Question

我遇到 nvarchar 类型的SQL Server问题，需要在Spring Boot Application中注册它。由于我正在调用现有的存储过程，因此我没有选择强制转换为查询。请建议我是否有其他方法来处理 nvarchar

我正在使用JPA存储库来调用存储过程

@Repository
public interface CustomRepo extends JpaRepository<ArchEntity, Long> {

   @Query(value = "{call dbo.storedproc(:objectType)}", nativeQuery = true)
   public List<Object> getData(@Param("objectType") String type);

}

属性

spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.datasource.initialize=false
spring.datasource.url=jdbc:sqlserver:**********
spring.datasource.username=*****
spring.datasource.password=*****

例外是

SQLServerDialect重写以在Spring Boot中注册nvarchar类型
