休眠在第一次插入表

2011-04-27 89 views

時，重複鍵'PRIMARY'的條目'1'當我第一次插入表時（在創建和刪除我的數據庫之後），我收到錯誤鍵'PRIMARY'的重複條目'1' 。這會導致回滾。如果我再次執行行插入確定。任何人都可以向我解釋爲什麼/我做錯了什麼？休眠在第一次插入表

我有一個用戶類（預填充在數據庫中），它有一個附加到它的任務列表。該數據庫擁有表的用戶，用戶的任務，任務

User.hbm包含

<id name="id" type="java.lang.Integer"> 
      <column name="id" /> 
      <generator class="increment" /> 
     </id> 
<list name="tasks" cascade="all" table="user_tasks" lazy="false"> 
      <key column="user_id"/> 
      <index column="id"/> 
      <many-to-many column="task_id" class="com.some.package.classes.Task"/> 
     </list>`

Task.hbm包含

<id name="id" type="java.lang.Integer"> 
     <column name="id" /> 
     <generator class="increment" /> 
    </id> 
<list name="users" cascade="all" table="user_tasks" lazy="false" 
    inverse="false"> 
     <key column="task_id"/> 
     <index column="id"/> 
     <many-to-many column="user_id" class="com.some.packageclasses.User"/> 
    </list>

只是好奇知道。爲什麼選擇使用XML配置而不是註釋？或者這是一個遺留項目？ – 2011-04-27 14:43:55

我對此很新。我用MyEclipse來生成休眠層。 – Chris 2011-04-27 15:19:57

Increment絕對不好，如果你有多個進程寫入相同的ta你一定會碰到碰撞。

所以用< generator class="identity"/>試試。

恐怕我已經嘗試了本機和身份認證，但都在第一次嘗試插入時產生相同的錯誤。 – Chris 2011-04-27 15:21:15

這已經有一段時間，因爲我用HBM文件，但它不應該是：

<id name="id"> 
     <column name="id" /> 
     <generator class="native" /> 
    </id>

？

我已經與mysql結合使用本機，並從未有過這個問題。我也會建議使用JPA註釋i.o. hbm文件。看[這裏]（http://docs.jboss.org/hibernate/stable/annotations/reference/en/html/entity.html#entity-mapping-entity）瞭解更多信息。 – 2011-04-27 15:23:57

我在轉儲和恢復MySQL數據庫後出現同樣的錯誤。重新啓動應用程序服務器（在我的情況下是Tomcat）解決了這個問題。
