1. Clover传参
a. jobflow传到子graph(GraphParameters):
设值: 用全局GraphParameters传递，在ExecuteGraph中的output mapping中传参 $out.1.BATCH_SIZE='10'
取值：初始值为配置文件workspace.prm中设置的值， getParamValue("BATCH_SIZE")或者${BATCH_SIZE}
b. 同一个graph(Dictionary):
使用dictionary：dictionary.customer = "John Smith"; myCustomerID = isInteger(dictionary.customer);
使用dictionary：SetJobOutput, GetJobInput
2. Clover控件属性
a. ExecuteJobflow
Stop processing on fail: false -- 子jobflow出错时继续执行
Number of executors: ${NUMBER_OF_ITERATIONS} -- 子jobflow并行数量
b. DBInputTable, DBOutputTable
Batch size: -- ${BATCH_SIZE}, 批量处理数据库请求
Commit: -- 100 (default) | 1-MAX_INT, Defines after how many records (without an error) commit is performed.
If set to MAX_INT, commit is never performed
Max error count: -- 0 (default) | 1-N | -1, By default, no error is allowed. If set to -1, all errors are allowed.
Action on error: -- COMMIT (default) | ROLLBACK, By default, when the number of errors exceeds Max error count, correct records
are committed into database.If set to ROLLBACK, no commit of the current batch is performed.
DBInputTable和DBExecute前面连接控件时，应传入Query URL: port:$0.sql:discrete(可先用Reformat拼接好sql再传入), 不能直接在SQL Query写sql操作语句
