新建包cn.itbaizhan
将logetl项目中的common和util包下的类拷贝到cn.itbaizhan下
修改cn.itbaizhan.common.GlobalConstants类,添加一下内容:
xxxxxxxxxx
//定义的output collector的前缀
public static final String OUTPUT_COLLECTOR_KEY_PREFIX = "collector_";
//指定连接表配置为report
public static final String WAREHOUSE_OF_REPORT = "report";
//批量执行的key
public static final String JDBC_BATCH_NUMBER = "mysql.batch.number";
//默认批量大小
public static final String DEFAULT_JDBC_BATCH_NUMBER = "500";
// driver 名称
public static final String JDBC_DRIVER = "mysql.%s.driver";
//JDBC URL
public static final String JDBC_URL = "mysql.%s.url";
//username名称
public static final String JDBC_USERNAME = "mysql.%s.username";
//password名称
public static final String JDBC_PASSWORD = "mysql.%s.password";
将log4j.properties、output-collector.xml、query-mapping.xml、transformer-env.xml文件拷贝到resources目录下。
如果mysql安装的不在node1上修改transformer-env.xml的如下代码:
xxxxxxxxxx
<property>
<name>mysql.report.url</name>
<value>jdbc:mysql://node1:3306/result_db?useUnicode=true&characterEncoding=utf8</value>
</property>
如果mysql的密码不是123456,修改transformer-env.xml的如下代码:
xxxxxxxxxx
<property>
<name>mysql.report.password</name>
<value>123456</value>
</property>
