Spring Data JPA OrderBy不起作用[小写字母] [大写字母]类型参数

Question

嗨〜我在使用Spring Data JPA时遇到了麻烦。这个麻烦github网址：https://github.com/moregorenine/toyproject/tree/jpa_self_join_save/tree-structure-ztree

开发环境spring-boot-starter-parent：2.0.6.RELEASE + JPA + H2 spring data jpa参考：https://docs.spring.io/spring-data/jpa/docs/current/reference/html/

一切正常。除了一个。

不工作参数类型：[小写字母] [大写字母] ... ex）tId

如果将{tId}更改为{tempId}是好工作！但我想用{tId}

Z tree service.Java

good work! no problem exmaple!!!

(O) zTrees = zTreeRepository.findAllByOrderById();
(O) zTrees = zTreeRepository.findAllByOrderByName();
(O) zTrees = zTreeRepository.findAllByOrderByIsParent();

don't work! only this type exmaple!!! why~

(X) zTrees = zTreeRepository.findAllByOrderByTId();

tId类型参数可以创建，从弹簧数据JPA插入。但'OrderBy'方法不支持[小写字母] [大写字母]类型参数吗？

Z tree.Java

package com.github.moregorenine.ztree.domain;

import java.util.HashSet;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Transient;
import javax.validation.constraints.NotBlank;

@Entity
public class ZTree {
    @Id
    @GeneratedValue
    private Long id; // 본인 id
    private String tId; // Ztree 내장 id
    @Transient
    private String parentTId; // Ztree 내장 pId
    @Transient
    private Long level; // lvl : 같은 그룹내 계층
    @NotBlank(message = "Name을 작성해주세요.")
    private String name;
    private String isParent;
    private String url; // 메뉴에 연결할 url
    private String useYn; // 메뉴 사용여부
    @ManyToOne(cascade={CascadeType.ALL})
    @JoinColumn(name="pId")
    private ZTree parent;
    @OneToMany(mappedBy="parent", cascade={CascadeType.ALL})
    private Set<ZTree> children = new HashSet<ZTree>();
}

Z tree service.Java

@Service
public class ZTreeService {

    @Autowired
    private ZTreeRepository zTreeRepository;

    public List<ZTree> getAllZTrees() {
        List<ZTree> zTrees = new ArrayList<>();
        zTrees = zTreeRepository.findAllByOrderByTId();
        return zTrees;
    }
}
