流水线部署中，单元测试覆盖率是一项考量的基本指标.本文介绍，在springboot3项目中，如何集成jacoco插件，以便在流水线SonarQube 中展示单元测试覆盖率报告.

主要注意的问题：

1.在引用依赖的时候，jmokit的依赖要先于junit的依赖。

<!-- jmockit --><dependency><groupId>mockit</groupId><artifactId>jmockit</artifactId><version>${jmockit.version}</version><scope>test</scope></dependency><!-- junit 5--><dependency><groupId>org.junit.platform</groupId><artifactId>junit-platform-launcher</artifactId><scope>test</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-engine</artifactId><scope>test</scope></dependency><dependency><groupId>org.junit.vintage</groupId><artifactId>junit-vintage-engine</artifactId><scope>test</scope></dependency>

2.surefire-maven-plugin，需要指定jmockit jar以及生成jacoco.exec位置，便于生成测试报告.

<plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><image><builder>paketobuildpacks/builder-jammy-base:latest</builder></image><excludes><exclude><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></exclude></excludes></configuration></plugin><!-- 配置Jacoco Maven插件 --><plugin><groupId>org.jacoco</groupId><artifactId>jacoco-maven-plugin</artifactId><version>${jacoco.version}</version><configuration><!-- jacoco生成报告时，排除和统计的文件 --><excludes><exclude>**/dto/**</exclude><exclude>**/domain/**</exclude></excludes><includes><include>**/service/**</include><include>**/util/**</include></includes></configuration><executions><execution><goals><goal>prepare-agent</goal></goals></execution><execution><id>report</id><phase>test</phase><goals><goal>report</goal></goals></execution></executions></plugin><!-- 配置Surefire插件 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-surefire-plugin</artifactId><version>3.0.0-M7</version> <!-- 使用支持Spring Boot 3的Surefire版本 --><configuration><argLine><!-- jdk 9 及以后，需要指定 jmockit-->-javaagent:${settings.localRepository}/org/jmockit/jmockit/${jmockit.version}/jmockit-${jmockit.version}.jar<!-- 指定jacoco.exec的位置,用于生成jacoco报告 -->-javaagent:${settings.localRepository}/org/jacoco/org.jacoco.agent/${jacoco.version}/org.jacoco.agent-${jacoco.version}-runtime.jar=destfile=${project.basedir}/target/jacoco.exec</argLine></configuration></plugin>

更过，demo可以自行下载。
