最近用到国密sm3算法,报错 java.lang.SecurityException: class “org.bouncycastle.crypto.digests.GeneralDigest

最近用到 国密sm3算法,报错 java.lang.SecurityException: class "org.bouncycastle.crypto.digests.GeneralDigest"'s signer information does not match signer information of other classes in the same package
    
一、原因
jar 包冲突


二、解决
*尝试方案一:
项目是maven项目,使用命令:dependency:tree -Dverbose -Dincludes=:bcprov-jdk
找出此bcprov-jdk14-136.jar包的依赖关系,如下所示:

mvn dependency:tree -Dverbose -Dincludes=:bcprov-jdk

[INFO] Verbose not supported since maven-dependency-plugin 3.0
。。。

提示不支持,继续尝试

*尝试方案二:
dependency:tree

手动查找 关键词bcprov-jdk

涉及到的jar,进行排除即可:
            <exclusions>
                <exclusion>
                    <groupId>org.bouncycastle</groupId>
                    <artifactId>bcprov-jdk14</artifactId>
                </exclusion>
            </exclusions>

三、排查问题用到的几个点:
    org/bouncycastle/crypto/digests/SM3Digest

  <!--<dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcprov-jdk15to18</artifactId>
            <version>1.68</version>
        </dependency>-->

        <!--<dependency>
            <groupId>org.bouncycastle</groupId>
            <artifactId>bcprov-jdk15on</artifactId>
            <version>1.60</version>
        </dependency>-->
