OFBiz 12.4 数据库转变成Mysql

使用OFBiz12.4的版本做数据库迁移，主要下面的步骤

1.修改entityengine.xml(framework/entiry/config/)

1)修改数据库连接,将derby的连接信息改成mysql

<delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false">
        <!-- 
        <group-map group-name="org.ofbiz" datasource-name="localderby"/>
        <group-map group-name="org.ofbiz.olap" datasource-name="localderbyolap"/>
        <group-map group-name="org.ofbiz.tenant" datasource-name="localderbytenant"/> -->
        <group-map group-name="org.ofbiz" datasource-name="localmysql"/>
        <group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
        <group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>
        <!-- <group-map group-name="org.ofbiz" datasource-name="localpostnew"/>
        <group-map group-name="org.ofbiz.olap" datasource-name="localpostolap"/>
        <group-map group-name="org.ofbiz.tenant" datasource-name="localposttenant"/> -->
</delegator>

2)分别修改这三个数据库的连接信息

localmysql数据库,字符，连接数据库url,用户名密码

<datasource name="localmysql"
            helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
            field-type-name="mysql"
            check-on-start="true"
            add-missing-on-start="true"
            check-pks-on-start="false"
            use-foreign-keys="true"
            join-style="ansi-no-parenthesis"
            alias-view-columns="false"
            drop-fk-use-foreign-key-keyword="true"
            table-type="InnoDB"
            character-set="utf8"
            collate="utf8_general_ci">
        <read-data reader-name="tenant"/>
        <read-data reader-name="seed"/>
        <read-data reader-name="seed-initial"/>
        <read-data reader-name="demo"/>
        <read-data reader-name="ext"/>
        <inline-jdbc
                jdbc-driver="com.mysql.jdbc.Driver"
                jdbc-uri="jdbc:mysql://localhost:3306/ofbiz?autoReconnect=true"
                jdbc-username="ofbiz"
                jdbc-password="ofbiz"
                isolation-level="ReadCommitted"
                pool-minsize="2"
                pool-maxsize="250"
                time-between-eviction-runs-millis="600000"/>
    </datasource>

localmysqlolap数据库的相关信息

<datasource name="localmysqlolap"
            helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
            field-type-name="mysql"
            check-on-start="true"
            add-missing-on-start="true"
            check-pks-on-start="false"
            use-foreign-keys="true"
            join-style="ansi-no-parenthesis"
            alias-view-columns="false"
            drop-fk-use-foreign-key-keyword="true"
            table-type="InnoDB"
            character-set="utf8"
            collate="utf8_general_ci">
        <read-data reader-name="tenant"/>
        <read-data reader-name="seed"/>
        <read-data reader-name="seed-initial"/>
        <read-data reader-name="demo"/>
        <read-data reader-name="ext"/>
        <inline-jdbc
                jdbc-driver="com.mysql.jdbc.Driver"
                jdbc-uri="jdbc:mysql://localhost:3306/ofbizolap?autoReconnect=true"
                jdbc-username="ofbiz"
                jdbc-password="ofbiz"
                isolation-level="ReadCommitted"
                pool-minsize="2"
                pool-maxsize="250"
                time-between-eviction-runs-millis="600000"/>
    </datasource>

localmysqltenant相关信息

<datasource name="localmysqltenant"
            helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
            field-type-name="mysql"
            check-on-start="true"
            add-missing-on-start="true"
            check-pks-on-start="false"
            use-foreign-keys="true"
            join-style="ansi-no-parenthesis"
            alias-view-columns="false"
            drop-fk-use-foreign-key-keyword="true"
            table-type="InnoDB"
            character-set="utf8"
            collate="utf8_general_ci">
        <read-data reader-name="tenant"/>
        <read-data reader-name="seed"/>
        <read-data reader-name="seed-initial"/>
        <read-data reader-name="demo"/>
        <read-data reader-name="ext"/>
        <inline-jdbc
                jdbc-driver="com.mysql.jdbc.Driver"
                jdbc-uri="jdbc:mysql://localhost:3306/ofbiztenant?autoReconnect=true"
                jdbc-username="ofbiz"
                jdbc-password="ofbiz"
                isolation-level="ReadCommitted"
                pool-minsize="2"
                pool-maxsize="250"
                time-between-eviction-runs-millis="600000"/>
    </datasource>

2.将mysql.jar放在framework/base/lib/下面

3.登录mysql，创建三个数据库，名字分别是：localmysql，localmysqlolap和localmysqltenant

4.创建用户ofbiz，密码ofbiz(这个和上面配置一样就可以)，并赋予用户权限。

5.使用antload-demostart重新建表
