如何在Spring Boot应用程序中添加非标准化的sql函数？

import org.hibernate.dialect.function.StandardSQLFunction;
import org.hibernate.dialect.function.SQLFunctionTemplate;
import org.hibernate.dialect.function.VarArgsSQLFunction;
import org.hibernate.dialect.AbstractSQLDialect;

public class CustomDialect extends AbstractSQLDialect {
    
    public CustomDialect() {
        super();
        // 注册非标准化的SQL函数
        registerFunction("custom_function", new StandardSQLFunction("custom_function"));
    }
}

spring.jpa.database-platform=com.example.CustomDialect

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
    
    @Query(value = "SELECT * FROM users WHERE custom_function(name) = :value", nativeQuery = true)
    List<User> findByCustomFunction(@Param("value") String value);
}
