什么是 <hbm2ddl/> hibernate3-maven-plugin-3.0的配置選項？

Question

我似乎找不到有關hbm2ddl的配置選項的任何文檔。 這是我的pom.xml中的內容：

<plugin>
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema -->
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>hibernate3-maven-plugin</artifactId>
    <version>3.0</version>

    <configuration>
        <hibernatetool>
            <annotationconfiguration
                    propertyfile="src/main/resources/hibernate.cfg.xml" />
            <hbm2ddl update="true" create="true" drop="true" export="false"
                     outputfilename="shemaDiff.ddl" format="true"
                     console="false"/>
        </hibernatetool>
    </configuration>
</plugin>

如果我跑步

mvn hibernate3:hbm2ddl

它構建成功，但是我檢查時數據庫為空。

.script文件如下所示：

SET DATABASE UNIQUE NAME HSQLDB3AAEB9E84A
SET DATABASE GC 0
SET DATABASE DEFAULT RESULT MEMORY ROWS 0
SET DATABASE EVENT LOG LEVEL 0
SET DATABASE SQL NAMES FALSE
SET DATABASE SQL REFERENCES FALSE
SET DATABASE SQL SIZE TRUE
SET DATABASE SQL TYPES FALSE
SET DATABASE SQL TDC DELETE TRUE
SET DATABASE SQL TDC UPDATE TRUE
SET DATABASE SQL TRANSLATE TTI TYPES TRUE
SET DATABASE SQL CONCAT NULLS TRUE
SET DATABASE SQL NULLS FIRST TRUE
SET DATABASE SQL UNIQUE NULLS TRUE
SET DATABASE SQL CONVERT TRUNCATE TRUE
SET DATABASE SQL AVG SCALE 0
SET DATABASE SQL DOUBLE NAN TRUE
SET DATABASE SQL LONGVAR IS LOB FALSE
SET DATABASE TRANSACTION CONTROL LOCKS
SET DATABASE DEFAULT ISOLATION LEVEL READ COMMITTED
SET DATABASE TRANSACTION ROLLBACK ON CONFLICT TRUE
SET DATABASE TEXT TABLE DEFAULTS ''
SET FILES WRITE DELAY 500 MILLIS
SET FILES BACKUP INCREMENT TRUE
SET FILES CACHE SIZE 10000
SET FILES CACHE ROWS 50000
SET FILES SCALE 8
SET FILES LOB SCALE 32
SET FILES DEFRAG 0
SET FILES NIO TRUE
SET FILES NIO SIZE 256
SET FILES LOG TRUE
SET FILES LOG SIZE 50
CREATE USER SA PASSWORD DIGEST 'd41d8cd98f00b204e9800998ecf8427e'
ALTER USER SA SET LOCAL TRUE
CREATE SCHEMA PUBLIC AUTHORIZATION DBA
ALTER SEQUENCE SYSTEM_LOBS.LOB_ID RESTART WITH 1
SET DATABASE DEFAULT INITIAL SCHEMA PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.YES_OR_NO TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.TIME_STAMP TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.CARDINAL_NUMBER TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.CHARACTER_DATA TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.SQL_IDENTIFIER TO PUBLIC
GRANT DBA TO SA
SET SCHEMA SYSTEM_LOBS
INSERT INTO BLOCKS VALUES(0,2147483647,0)

有趣的是，如果我設置console =“ true”，它將打印正確的sql表設置：

create table ACCOUNT (
    ACCOUNT_ID integer generated by default as identity (start with 1),
    ...
);

create table ... etc.

如果我降級到2.2版，則該插件如下所示：

<plugin>
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema -->
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>hibernate3-maven-plugin</artifactId>
    <version>2.2</version>
</plugin>

並（不進行任何更改）運行mvn hibernate3：hbm2ddl，然后從帶注釋的類中正確創建數據庫表，並且.script文件反映了這一點：

SET DATABASE UNIQUE NAME HSQLDB3AAEB9E84A
SET DATABASE GC 0
SET DATABASE DEFAULT RESULT MEMORY ROWS 0
SET DATABASE EVENT LOG LEVEL 0
SET DATABASE SQL NAMES FALSE
SET DATABASE SQL REFERENCES FALSE
SET DATABASE SQL SIZE TRUE
SET DATABASE SQL TYPES FALSE
SET DATABASE SQL TDC DELETE TRUE
SET DATABASE SQL TDC UPDATE TRUE
SET DATABASE SQL TRANSLATE TTI TYPES TRUE
SET DATABASE SQL CONCAT NULLS TRUE
SET DATABASE SQL NULLS FIRST TRUE
SET DATABASE SQL UNIQUE NULLS TRUE
SET DATABASE SQL CONVERT TRUNCATE TRUE
SET DATABASE SQL AVG SCALE 0
SET DATABASE SQL DOUBLE NAN TRUE
SET DATABASE SQL LONGVAR IS LOB FALSE
SET DATABASE TRANSACTION CONTROL LOCKS
SET DATABASE DEFAULT ISOLATION LEVEL READ COMMITTED
SET DATABASE TRANSACTION ROLLBACK ON CONFLICT TRUE
SET DATABASE TEXT TABLE DEFAULTS ''
SET FILES WRITE DELAY 500 MILLIS
SET FILES BACKUP INCREMENT TRUE
SET FILES CACHE SIZE 10000
SET FILES CACHE ROWS 50000
SET FILES SCALE 8
SET FILES LOB SCALE 32
SET FILES DEFRAG 0
SET FILES NIO TRUE
SET FILES NIO SIZE 256
SET FILES LOG TRUE
SET FILES LOG SIZE 50
CREATE USER SA PASSWORD DIGEST 'd41d8cd98f00b204e9800998ecf8427e'
ALTER USER SA SET LOCAL TRUE
CREATE SCHEMA PUBLIC AUTHORIZATION DBA
SET SCHEMA PUBLIC
CREATE MEMORY TABLE PUBLIC.ACCOUNT(ACCOUNT_ID INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH 1) NOT NULL PRIMARY KEY, ...)
ALTER TABLE PUBLIC.ACCOUNT ALTER COLUMN ACCOUNT_ID RESTART WITH 1
...
ALTER SEQUENCE SYSTEM_LOBS.LOB_ID RESTART WITH 1
SET DATABASE DEFAULT INITIAL SCHEMA PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.YES_OR_NO TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.TIME_STAMP TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.CARDINAL_NUMBER TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.CHARACTER_DATA TO PUBLIC
GRANT USAGE ON DOMAIN INFORMATION_SCHEMA.SQL_IDENTIFIER TO PUBLIC
GRANT DBA TO SA
SET SCHEMA SYSTEM_LOBS
INSERT INTO BLOCKS VALUES(0,2147483647,0)

有誰知道hbm2ddl的配置是什么，以便使用hibernate3-maven-plugin-3.0正確創建表？

Answer 1

我仍然沒有找到文檔，但是我設法通過hibernate3-maven-plugin-3.0來獲取hbm2ddl來構建表。

插件的外觀如下所示：

<plugin>
    <!-- Run "mvn hibernate3:hbm2ddl" to generate schema -->
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>hibernate3-maven-plugin</artifactId>
    <version>3.0</version>

    <configuration>
        <hibernatetool>
            <classpath>
                <path location="${project.build.directory}/classes" />
            </classpath>

            <annotationconfiguration
                    propertyfile="src/main/resources/hibernate.cfg.xml" />
            <hbm2ddl update="true" create="true" drop="true" export="false"
                     outputfilename="schemaDiff.ddl" format="true"
                     console="true"/>
        </hibernatetool>
    </configuration>

</plugin>

希望這對某人有幫助！
