我使用hibernate/jpa註釋來自動創建/執行DDL腳本。休眠SQL DDL腳本錯誤150，無法使外鍵約束
我所有的表格都在創建，除了所有表格上的一個表「UserAccount」和外鍵「contraints」。
當檢查了Apache Tomact登錄我發現了幾個錯誤類似的錯誤：
錯誤輸出：
重度：不成功：創建表USER_ACCOUNT（user_ID的BIGINT NOT NULL AUTO_INCREMENT，有效位，ADDRESS_1 VARCHAR（255） ，address_2 varchar（255），email varchar（255），first_name varchar（255），last_name varchar（255），phone_contact_1 varchar（255），phone_contact_2 varchar（255），user_type varchar（255），Registeration_Code_fk bigint not null，primary key（user_id）） 2012年6月11日下午6:42:42 org.hibernate.tool.hbm2ddl.SchemaExport創建
嚴重：你的SQL語法有錯誤;請檢查與您的MySQL服務器版本相對應的手冊，以便在第1行'_name varchar（255），last_name varchar（255），phone_contact_1 varchar（255），phone_'附近使用正確的語法。 Jun 11，2012 6:42： 42 PM org.hibernate.tool.hbm2ddl.SchemaExport創建
重度：不成功：ALTER TABLE Indust_Of_Interest添加索引FKBCDB75CAF90F35D9（USER_ID），加約束FKBCDB75CAF90F35D9外鍵（USER_ID）引用USER_ACCOUNT（USER_ID） 2012年6月11日6： 42:42 PM org.hibernate.tool.hbm2ddl.SchemaExport創建
重度：無法創建表 'yourmarketnet＃SQL-584_86c'（錯誤：150）
等等......
1）我的第一個問題是讓hibernate生成正確的SQL DDL語法（這個錯誤很奇怪，因爲Hibernate給出正確的SQL方言應該很容易生成正確的SQL DLL）？我的第二個問題是關於外鍵錯誤（errno：150），我在手工創建DDL之前看到過這個錯誤/錯誤，但是我怎麼能通過Hibernate修復它？
