hibernate＆spring，無效標識符

我一直堅持在春天的mvc環境中使用hibernate orm來處理數據庫。hibernate＆spring，無效標識符

我有一些表;但我不會告訴你我的表（如果你想，我會編輯這篇文章）

問題是，當hibernate運行時，它會生成sql - 我可以通過配置「hbm2_ddl auto」來看到sql - 但sql有無效的標識符。

select newsreplie0_.news_article# as news6_3_4_, newsreplie0_.reply# as reply1_4_, 
newsreplie0_.reply# as reply1_4_3_, newsreplie0_.account_account# as account5_4_3_, 
newsreplie0_.content as content4_3_, newsreplie0_.dt as dt4_3_, 
newsreplie0_.news_article# as news6_4_3_, newsreplie0_.reply_at as reply4_4_3_, 
account1_.account# as account1_0_0_, account1_.email as email0_0_, 
account1_.passwd as passwd0_0_, accountpro2_.account# as account1_1_1_, 
accountpro2_.nickname as nickname1_1_, accountsec3_.account# as account1_2_2_, 
accountsec3_.activate_key as activate2_2_2_, accountsec3_.activated as activated2_2_, 
accountsec3_.enabled as enabled2_2_, accountsec3_.login_failed as login5_2_2_ 
from news_reply newsreplie0_ 
left outer join 
cookingstep.account account1_ on newsreplie0_.account_account#=account1_.account# 
left outer join 
cookingstep.account_profile accountpro2_ on account1_.account#=accountpro2_.account# 
left outer join 
cookingstep.account_security accountsec3_ on account1_.account#=accountsec3_.account# 
where newsreplie0_.news_article#=9 
{FAILED after 4 msec}

上述語句是由hibernate生成的一個sql語句。錯誤是：

java.sql.SQLSyntaxErrorException: 
ORA-00904: "NEWSREPLIE0_"."ACCOUNT_ACCOUNT#": Invalid Identifier

在該異常消息中，有一個名爲「ACCOUNT_ACCOUNT＃」的列。它應該是「ACCOUNT＃」，而不是「ACCOUNT_」。

那麼，如何刪除這個詞？

編輯：

謝謝大家的回覆。我曾問過類似的問題。我檢查了那篇文章，似乎問題是@JoinColumn註釋缺失。現在它解決了。

這是我的實體。

在NewsReply.java，沒有JoinColumn註解點foreing鍵列名。

謝謝。

你可以發佈你的ORM映射類嗎？ –

什麼是hibernate.hbm2ddl.auto設置爲？驗證，更新，創建，craete-drop？發佈您的實體類的帳戶。駱駝案件可能會欺騙你。 – kkflf

針對ORM映射類的更新文章。和hbm2ddl.auto屬性設置爲驗證 – PLAYMAKER

@ManyToOne 
@JoinColumn(name="account#", referencedColumnName="account#") 
public Account getAccount() { 
    return account; 
}

這是問題，你告訴Hibernate表有什麼是不允許的account#技術名稱。

你可以做的是強制Hibernate通過定義

@ManyToOne 
@JoinColumn(name="`account#`", referencedColumnName="`account#`") 
public Account getAccount() { 
    return account; 
}

使用該＃但是，這是不好的風格，你必須這樣做對所屬方太。

爲什麼不讓hibernate爲您創建實體？他更精確！
