在服务器上执行webApplication时如何获取JaCoCo工具代码覆盖率

本文介绍了在服务器上执行webApplication时如何获取JaCoCo工具代码覆盖率的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当我在实时应用程序上执行某些场景时(即，当应用程序在服务器上运行时)，我想获取代码覆盖率报告(或跟踪应用程序的控制器流)，因此我引用了官方的 Jacoco文档并作为休闲

I want to get a code coverage report (or tracking controller flow of an application) when I execute the some scenario on live application i.e. while application running in server, so I have refereed the official Jacoco documentation and did as fallows

第一步，我试图将jacoco代理绑定到运行端口的应用程序

As a first step, I tried to bind the jacoco agent to the application running port

export MAVEN_OPTS=-javaagent:/home/user/.m2/repository/org/jacoco/org.jacoco.agent/0.7.4.201502262128/org.jacoco.agent-0.7.4.201502262128-runtime.jar=includes=*,output=tcpserver,port=6300,address=*,dumponexit=true

那时候我已经启动了服务器并执行了一些测试方案，那时我还要求jacoco通过执行以下命令来获取转储

then I have started the server and executed some test scenarios by that time I have also requested jacoco to get the dump by executing following command

 mvn jacoco:dump

当我首先执行上述命令时，它显示为java.net.BindException: Address already in use，然后显示为休止符

when I executed the above command first it showed like java.net.BindException: Address already in use then it printed as fallows

[INFO] Connecting to localhost/127.0.0.1:6300

当我要求通过执行以下命令来生成jacoco报告后，当我停止服务器 jacoco.exec 到那里的已知位置时，

When I stopped the server jacoco.exec has been generated to a known location there after I have requested to generate a jacoco report by executing the following command

mvn jacoco:report

最后我得到了报告，但是当我打开index.html页面时，它显示了0%覆盖率.

Finally I got the report but when I open the index.html page it showed 0% coverage.

您可以通过以下示例Spring MVC项目来重现我的难题

you can reproduce my difficulty with following sample Spring MVC project

请从 https://github.com/mkyong/spring4下载Spring MVC项目-来自Github的-mvc-ajax-example

在我的情况下，我正在使用WildFly 8.x服务器运行项目并将以下依赖项添加到下载的项目pom.xml

In my case I am using WildFly 8.x server to run the project and add the following dependencies to downloaded projects pom.xml

 maven-surefire-plugin of 2.19.1 version
 jacoco-maven-plugin of 0.7.4.201502262128 version
 junit of 4.12 version

然后使用以下命令清理并构建项目.

Then clean and build the project by using following commands.

mvn clean install

完成后，从项目的目标文件夹中获取.war文件，并将其保存在wildfly serverwildfly-9.0.0.CR2/standalone/deployments/文件夹中

once it is done get the .war file from target folder of the project and keep inside the wildfly serverwildfly-9.0.0.CR2/standalone/deployments/ folder

一旦部署了.war，请转到/wildfly-9.0.0.CR2/bin/文件夹并执行/运行./standalone.sh文件，或者根据平台的不同，您可以运行.dat/.sh文件

Once the .war is deployed go to /wildfly-9.0.0.CR2/bin/ folder and execute/run the ./standalone.sh file or depending on platform you can run the.dat/.sh file

一旦部署项目并启动服务器，请执行以下命令

once project is deployed and server is started execute the following command

mvn jacoco:dump

它显示为聆听/已连接到localhost/127.0.0.1:6300

it displayed like listening/connected to localhost/127.0.0.1:6300

然后执行一些测试方案并执行以下maven命令

Then execute some test scenarios and execute following maven command

mvn jaococ:report

最终将以0％的覆盖率生成报告！.

Finally report will be generated with 0% coverage!.
