ADF是oracle提供的一套企业开发的解决方案,本文将实现在ADF中跟踪SQL执行时间
ADF是oracle提供的一套企业开发的解决方案。最近做性能测试， 需要获取当前页面有多少SQL 查询，花费多少时间。首先想到的就是常用的log4jdbc 结果 ADF 不支持封装的驱动。后尝试在Orace DB 层面上拦截，比较复杂还要设置数据库连接的sesson属性，也要修改以后代码。
ADF 的ViewObjectImp 提供复写SQL调用的方法，但需要修改已有代码，最后还是修改ADF源码来达到不修改已有代码而获取到SQL执行时间。
先用改好的adfm.jar 覆盖已有的， 配置虚拟机启动参数 -DSQLTruckerToFile=D:\log.txt -DenableSQLTracker=true
重启就可以看到SQL 执行时间了
