watch

  • 查看session中的属性

    1. watch *.ApplyInstanceController list '{params[0].request.session.session.attributes.systemUser}' -n 1 -x 3

  • 查看httpServletRequest paramter

    1. watch *.x x 'params[0].request.parameters.paramHashValues.publishCode' -n 4 -x 3

  • 查看ArrayList的第几个数据

    1. watch *.QueryServiceImpl queryIpInfoByGroup '{params[0].get(1)}' -n 3 -x 3

  • 查看目标对象的变量(这里使用的是ognl表达式)

    1. watch *.QueryServiceImpl handle '{target,target.profile}' -n 1 -x 3

  • 查看执行的sql (mysql) 测试坏境不频繁可以使用。 太频繁的获取不到 ```bash watch com.mysql.jdbc.ConnectionImpl execSQL ‘{params[0].originSql}’ -n 5 -x 3 —mysql 驱动

watch org.apache.ibatis.executor.statement.PreparedStatementHandler query ‘{params[0]}’ -n 5 -x 1 ‘params[0].wrapper.asSql().contains(“sql的内容”)’

  1. <a name="GExbS"></a>
  2. ### monitor
  4. - 查看某一个用户的执行频繁
  5. ```bash
  6. monitor *.MyMessageClientListener handleTag "params[0].fourth.{?#this.nick=='vavaxinxin'}" -c 5

ognl

  • 查看静态字段(private,public)

    1. ognl '@io.github.bootmybatis.service.QueryServiceImpl@ddss'

    trace

  • ognl 条件过滤

    1. trace com.raycloud.operation.ons.Tmc.MyMessageClientListener handleRefundCreate -n 5 'params[0].fourth.id=="2525634019"'

    stace

  • 查看堆栈

    vmtool 查看实例数量 or 调用实例方法
