4：使用javacc插件编译目录下的.jj文件右击 - Compile with javacc

文件目录：/项目名称/framework/base/src/org/ofbiz/base/json/JSON.jj

/项目名称/framework/sql/src/org/ofbiz/sql/Parser.jj

5：修改数据库配置信息

打开/项目名称/framework/entity/config/entityengine.xml

以mysql为例，用户名密码自定义，在mysql新建3个数据库分别为ofbiz，ofbizolap，ofbiztenant

找到下面这段修改打开mysql段的注释（这里删除了mysql的上下两段注释的代码）

<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="localmysql"/><group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/><group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/></delegator><delegator name="default-no-eca" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" entity-eca-enabled="false" distributed-cache-clear-enabled="false"><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"/>
</delegator>
<delegator name="test" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main"><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"/>
</delegator>

此处设置数据库连接地址，用户名密码以及字符编码

<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"/><read-data reader-name="ext-test"/><read-data reader-name="ext-demo"/><inline-jdbcjdbc-driver="com.mysql.jdbc.Driver"jdbc-uri="jdbc:mysql://localhost:3306/ofbiz?autoReconnect=true"jdbc-username="用户名"jdbc-password="密码"isolation-level="ReadCommitted"pool-minsize="2"pool-maxsize="250"time-between-eviction-runs-millis="600000"/>
</datasource><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"/><read-data reader-name="ext-test"/><read-data reader-name="ext-demo"/><inline-jdbcjdbc-driver="com.mysql.jdbc.Driver"jdbc-uri="jdbc:mysql://localhost:3306/ofbizolap?autoReconnect=true"jdbc-username="用户名"jdbc-password="密码"isolation-level="ReadCommitted"pool-minsize="2"pool-maxsize="250"time-between-eviction-runs-millis="600000"/>
</datasource><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"/><read-data reader-name="ext-test"/><read-data reader-name="ext-demo"/><inline-jdbcjdbc-driver="com.mysql.jdbc.Driver"jdbc-uri="jdbc:mysql://localhost:3306/ofbiztenant?autoReconnect=true"jdbc-username="用户名"jdbc-password="密码"isolation-level="ReadCommitted"pool-minsize="2"pool-maxsize="250"time-between-eviction-runs-millis="600000"/>
</datasource>

5：添加数据库驱动以及JDBC驱动，下载地址百度

/项目名称/framework/entity/lib/jdbc/mysql-connector-java-5.1.41.jar

/项目名称/framework/entity/lib/jdbc/postgresql-9.1-903.jdbc4.jar

/工程名/framework/sql/src/org/ofbiz/sql/Parser.jj

6：初始化数据库中数据表以及初始化信息
打开-/项目名称/build.xml执行load-demo方法时间有点长，耐心等待

7： 启动程序

/ofbiz-release1307/framework/start/src/org/ofbiz/base/start/Start.java

8：效果展示 admin/ofbiz
