Tomcat启动报StackOverflowError

近期工程部署到Tomcat时，出现以下异常：

红色部分是主要问题，经查询，其中 [org.bouncycastle.asn1.ASN1Boolean->org.bouncycastle.asn1.DERBoolean->org.bouncycastle.asn1.ASN1Boolean ] 形成了环状继承关系，导致出现StackOverflowError，主要原因是Maven依赖引入了2个包，分别具有不同的继承关系，去除其中一个不需要的依赖即可

解决方法：

（1）在工程中找到ASN1Boolean和DERBoolean，发现有2个依赖包含着2个类，并且继承关系相反；

（2）2个依赖中有一个是间接依赖，将这个依赖排除在外即可，如下：

<dependency>
            <groupId> </groupId>
            <artifactId> </artifactId>
            <version> </version>
            <exclusions>
                <exclusion>
                    <groupId> </groupId>
                    <artifactId> </artifactId>
                </exclusion>
            </exclusions>
        </dependency>
