在集成测试期间,我使用spring-boot-maven-plugin启动我的spring应用程序:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<id>start-spring-boot</id>
<phase>pre-integration-test</phase>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>stop-spring-boot</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
现在,我想将JaCoCo代理添加到执行中,但是由于代理或jvmarguments无法将其添加到配置中。开始时,我总是看到:
[INFO] --- spring-boot-maven-plugin:2.2.4.RELEASE:start (start-spring-boot) @ tosca-ui ---
[INFO] Attaching agents: []
如何将JaCoCo与spring-boot-maven-plugin一起使用?
默认情况下,Spring Boot Maven插件会创建一个fork,必须明确指定代理配置。可以通过在Spring Boot Maven插件中设置<agents><agent>...</agent></agents>
配置属性来完成,但该方法不适用于Jacoco,因为没有惯用的方法来找出代理jar文件的确切路径。
相反,您可以将Jacoco设置的argLine
变量传递给Spring Boot Maven插件JVM参数:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>${argLine}</jvmArguments>
</configuration>
<executions>
<execution>
<id>start-spring-boot</id>
<phase>pre-integration-test</phase>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>stop-spring-boot</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
由于必须配置许多Maven插件才能使其正常运行,为避免混淆,这里是完整的pom.xml

有了这个,执行mvn clean verify
后,您就可以在target/site/jacoco/index.html
中找到Jacoco报告。
您可以在jacoco-spring-boot-maven-plugin-sample处找到完整的示例项目
