英文:
Jacoco instrumentation using tcp server method
问题
以下是您要翻译的内容：
我正在尝试在远程服务器上对我的Java代码运行集成测试，因此每当我的测试命中我的代码服务器时，Jacoco都会记录它。
我对Jacoco还不太了解，到目前为止，我已经了解到有一种无需重新启动的TCP服务器方法。
1）我在我的/etc/profile中添加了以下行。
export JAVA_OPTS="-javaagent:/home/vansh/jacoco/lib/jacocoagent.jar=address=*,port=57026,destfile=/home/vansh/jacoco/jacoco.exec,output=tcpserver"
2）但是当我尝试使用以下命令进行转储时 -
java -jar jacococli.jar dump --address localhost --port 57026 --destfile /home/vansh/jacoco/jacoco-it.exec
错误：
[INFO] 正在连接到 localhost/127.0.0.1:57026。
[WARN] 拒绝连接 (Connection refused)。
[INFO] 正在连接到 localhost/127.0.0.1:57026。
Exception in thread "main" java.net.ConnectException: 拒绝连接 (Connection refused)

at java.base/java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:224)
at java.base/java.net.SocksSocketImpl.connect(SocksSocketImpl.java:403)
我检查了一下，端口57026上没有任何运行的内容，我的第一个javaagent命令是正确的吗？
英文:
I am trying to run integration tests on my java code from remote server, so whenever my tests hit my code server, jacoco records it.
I am new to jacoco, till now i have gather that there is tcp server method which doesnot require any restart.
- I have added below line in my /etc/profile.
export JAVA_OPTS="-javaagent:/home/vansh/jacoco/lib/jacocoagent.jar=address=*,port=57026,destfile=/home/vansh/jacoco/jacoco.exec,output=tcpserver"
2)but when i am trying to take dump using below command -
java -jar jacococli.jar dump --address localhost --port 57026 --destfile /home/vansh/jacoco/jacoco-it.exec
ERROR:
[INFO] Connecting to localhost/127.0.0.1:57026.
[WARN] Connection refused (Connection refused).

I checked that there is nothing run on port 57026, is my first command javaagent one is correct?

我在一年前做过同样的事情，在我的情况下，我运行一个TCP_Client的jar文件来收集dump，有多种方式（周期性地/带有和不带有重置先前覆盖的选项）。
我设置了JAVA_OPTS如下，
-javaagent: <jacoco_agent的文件路径>/jacocoagent.jar=output=tcpserver,address=*,port=6300
这是我TCP客户端的仓库链接 - 点击此处进入链接
将固定的参数设置到代码中或使用此仓库创建一个jar文件
如果你从这段代码中运行一个jar文件，
你可以通过传递“address”“port”“dump文件夹路径”“定期转储时间”“每次转储都重置选项”参数来运行这个jar文件。
示例：java -jar ExecutedDataDump.jar“127.0.0.1”“6300”“D:\server-dumplog\”“5”“noreset”
你将会在每5秒钟的时间间隔内得到带有时间戳的jacoco.exec文件，并且由于noreset选项，每个jacoco.exec文件都会获得累积报告
希望这对你有所帮助。
英文:
I have done same thing a year ago, In my case I run a TCP_Client jar for collecting the dump with many ways(periodically/with and without resetting previous coverage).
I set JAVA_OPTS as follows,
-javaagent:<file_Path_for_jacoco_agent>/jacocoagent.jar=output=tcpserver,address=*,port=6300
Here is my repo link of tcp client - enter link description here
set fixed arguments to the code or create a jar with this repo
If you are running a jar from this code,
You can run this jar with passing "address" "port" "dump-folder-path" "periodic-time-for-dumping" "resetting-option-with-every-dump" arguments.
example : java -jar ExecutedDataDump.jar "127.0.0.1" "6300" "D:\\server-dumplog\\" "5" "noreset"
You will get get jacoco.exec files with time stamp in every 5 secs time and due to noreset every jacoco.exec is get cumulative report
Hope this will helpful for you.
