< p > 通过getstatic命令可以方便的查看类的静态属性。使用方法为< code class = "docutils literal notranslate" > < span class = "pre" > getstatic< / span > < span class = "pre" > class_name< / span > < span class = "pre" > field_name< / span > < / code > < / p >
< p > 如果该静态属性是一个复杂对象, 还可以支持在该属性上通过ognl表示进行遍历, 过滤, 访问对象的内部属性等操作。< / p >
< p > 例如, 假设n是一个Map, Map的Key是一个Enum, 我们想过滤出Map中Key为某个Enum的值, 可以写如下命令< / p >
< div class = "highlight-default notranslate" > < div class = "highlight" > < pre > < span > < / span > $ getstatic com.alibaba.arthas.Test n ' entrySet().iterator.{? #this.key.name()==" STOP" }'
