jdb和arthas联合调试代码

jdb -connect com.sun.jdi.SocketAttach:hostname=192.168.3.102,port=5005   或  jdb -attach 192.168.3.102:5005 
利用arthas中的jad找到想要debug的类然后反编译
[arthas@31407]$ jad com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect
比如部分代码如下
                 public void before(HttpServletRequest request, Object obj) throws WiseException {
/* 52*/         logger.info("[#requestUrl#]:{}\t[#requestJson#]:{}", (Object)request.getRequestURI(), (Object)JSONObject.fromObject((Object)obj).toString());
/* 53*/         String requestUri = request.getRequestURI();
/* 54*/         String contextPath = request.getContextPath();
/* 55*/         String url = requestUri.substring(contextPath.length());
/* 56*/         if (url.startsWith("/open/user/loginByLoginName") || url.startsWith("/open/user/loginByTicket") || url.startsWith("/open/user/loginByWorkCode") || url.startsWith("/login/user/logoutForCas") || url.startsWith("/common/getBase64") || url.startsWith("/focusmart/getCasUrl") || url.startsWith("/focusmart/casRedirect") || url.startsWith("/bi/") || url.startsWith("/open/deviceGoodsPr/getDeviceGoodsPrByDeviceCode") || url.startsWith("/open/getDeviceStatus") || url.startsWith("/open/getDeviceRateOfUtilization") || url.startsWith("/open/getDevceListForPage") || url.startsWith("/open/esl/getStoreGoodsByCode") || url.startsWith("/open/esl/getCustomizeStoreGoodsBySku") || url.startsWith("/coupon/getCouponInfoByStockIdH5") || url.startsWith("/coupon/sendCoupon")) {
/* 73*/             return;
                }
/* 75*/         Object baseDTO = null;
在full-class-path的第line-number行设置断点
stop at full-class-path:line-number
例如： stop at com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect:52 
执行后当代码调用到此处会停到此处
next 单步走
locals 打印全部局部变量
print <expr> 打印变量/表达式的值
例如： print requestUri 可以看到变量值
requestUri = "/market-portal-center/signal/listCreatedSignals"
已完成的步骤: "线程=http-nio-8080-exec-4", com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect.before(), 行=55 bci=38
执行locals得到所有变量
http-nio-8080-exec-4[1] locals
方法参数:
request = instance of org.apache.catalina.connector.RequestFacade(id=105279)
obj = instance of com.hanshow.wise.common.jo.BaseQUERY(id=106352)
本地变量:
requestUri = "/market-portal-center/signal/listCreatedSignals"
contextPath = "/market-portal-center"
cont 从断点处一直执行(如果没有下一个断点会执行完)
clear 显示所有断点
clear full-class-path:line-number 清除断点
> clear
断点集:
        断点com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect:52
> clear com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect:52
已删除: 断点com.hanshow.wise.portal.center.aspect.CenterLoginValidateAspect:52
