根据Activiti的processInstanceId得到流程图，高亮当前执行中的流程。 与官方提供的不同，该类仅仅是在原图的基础上添加高亮。这样可以不需要考虑汉字乱码的问题。

win32编译openjdk7u60环境变量设置

编译jdk7u60过程中的注意点:

  1. 先看目录下的README-builds.html，不要太认真看个大概就行
  2. 下载最新的Microsoft DirectX SDK，安装时路径不要带括号
  3. 安装procps代替free.exe(检查可用内存是会用到，没有应该也可以就是多个警告而已)
  4. cygwin-make的版本问题，使用3.81 snapshot
  5. VS2010的cl命令显示的信息一直是中文的话，需要修改源码跳过版本号的检查 snapshot
  6. 语言问题，导致编译corba失败！而后面有需要用到这个工程！ snapshot
  7. PATH顺序问题，link.exe和find.exe snapshot
  8. 编译时间有点长！ snapshot java-version

简书Markdown

一些使用注意点：

  • 由于简书使用[GFW]的拓展版的Markdown；
    • 内容换行被解析为
      ，2+个换行才被解析为

      ；

    • 代码块使用```；
    • 链接URL。
  • 4个空格相当于一个Tab；
  • 嵌套元素：关于空格的使用各个解析器好像都不同，有些严格遵循规范，在简书中，直接使用一个空格也行。多个换行会被解析为新元素。
