Question

我是hibernate的新手，我使用Netbeans示例项目生成了POJO表单数据库。一切似乎都正常，但在hbn和java文件中没有外键名称，这是一个问题，因为我想从POJO文件开始生成模式DDL

我的hibernate.cfg.xml

r.Dial customer_number, 
  :method => 'POST', 
  :timeout => '30',
  :calledId => "YOUR_VERIFIED_NUMBER"

hibernate.reveng.xml中

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
    <property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
    <property name="hibernate.connection.url">jdbc:oracle:thin:@server1:1521:orcl</property>
    <property name="hibernate.connection.username">TABLE_OWN</property>
    <property name="hibernate.connection.password">password</property>
    <property name="hibernate.default_schema">TABLE_OWN</property>
  </session-factory>
</hibernate-configuration>

原始DDL

<hibernate-reverse-engineering>
  <schema-selection match-schema="TAB_OWN"/>
  <table-filter match-name="TABLE1"/>
  <table-filter match-name="TABLE2"/>
  <table-filter match-name="TABLE3"/>
</hibernate-reverse-engineering>

hibernate生成的hbm文件

CREATE TABLE BJADRE
(
   RE_ADID varchar(14) NOT NULL,
   RE_ADID_SEQ varchar(2) NOT NULL,
   RE_ADSTAT varchar(1) NOT NULL,
   RE_ADFROM varchar(6) NOT NULL,
   RE_ADOPNO decimal(22,0) NOT NULL,
   RE_JSNAME varchar(16) DEFAULT ' '  NOT NULL,
   RE_REOPNO decimal(22,0) DEFAULT 0  NOT NULL,
   RE_COMPL varchar(1) DEFAULT ' '  NOT NULL,
   RE_JOBNAME varchar(40) DEFAULT ' '  NOT NULL,
   RE_JSWS varchar(16) DEFAULT ' '  NOT NULL,
   PRIMARY KEY (RE_ADID,RE_ADID_SEQ,RE_ADSTAT,RE_ADFROM,RE_ADOPNO)
)
ENGINE INNODB COLLATE=latin1_general_cs;
--
ALTER TABLE BJADRE
ADD CONSTRAINT BJADRE_FRE01
FOREIGN KEY
(
  RE_ADID,
  RE_ADID_SEQ,
  RE_ADSTAT,
  RE_ADFROM,
  RE_ADOPNO
)
REFERENCES BJADOP
(
  OP_ADID,
  OP_ADID_SEQ,
  OP_ADSTAT,
  OP_ADFROM,
  OP_ADOPNO
) ON DELETE CASCADE
;

在hbn中没有引用外键名称BJADRE_FRE01 hibernate生成以下名为FK74D139DE74DBF99B的外键

来自DB的Hibernate hbm和POJO不会生成外键名称
