单元测试中出现 Found multiple occurrences of org.json.JSONObject on the class path:

一、问题描述
在SpringBoot下使用Junit4进行单元测试，出现了Found multiple occurrences of org.json.JSONObject on the class path:
jar:file:/D:/apache-maven-3.3.9/maven-repository/org/json/json/20160810/json-20160810.jar!/org/json/JSONObject.class
jar:file:/D:/apache-maven-3.3.9/maven-repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class
二、 解决方案
在maven依赖中排除

 <!-- 单元测试-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>com.vaadin.external.google</groupId>
                    <artifactId>android-json</artifactId>
                </exclusion>
                
            </exclusions>
        </dependency>
