Spring Boot 在 Windows 运行单元测试报错

方法一：

发现json-smart-2.3.jar引起了报错，使用 Maven Helper 插件在 pom 中搜索这个 jar , 把这个 jar 排除掉，重新导入一下 pom, 再次运行单元测试，发现问题解决

 如果解决不了请看方法二

方法二：

在第一和第二标注的行之间加入代码

<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
			<exclusions>
				<exclusion>
					<artifactId>json-path</artifactId>
					<groupId>com.jayway.jsonpath</groupId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>

 手动添加
