jacoco之单元测试覆盖率

maven项目

在pom文件中增加jacoco插件

<properties>
    <maven.compiler.source>8</maven.compiler.source>
    <maven.compiler.target>8</maven.compiler.target>
    <jacoco.version>0.8.5</jacoco.version>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>${jacoco.version}</version>
            <configuration>
                <excludes>
                    <exclude>**/*Test.java</exclude>
                </excludes>
            </configuration>
            <executions>
                <execution>
                    <id>prepare-agent</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>report</id>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

其中，exclude表示过滤掉指定文件的单测覆盖率统计
