Cannot use SOFARegistry after upgrading sofa-boot 3.2.1

[HuangSheng]

升级sofa-boot到3.2.1版本后，SOFARegistry无法使用，只能使用zk做注册中心。检查代码发现是SofaRpcAutoConfiguration 这个类在做注入注册中心处理器实现时添加了 @ConditionalOnMissingBean 注解，导致只注入了local、mesh和zk的处理器，其它注册中心的处理器没有注入。不知为何要做这个配置？如果要使用新版本的话需要如何修改？

After upgrading sofa-boot to version 3.2.1, SOFARegistry cannot be used, and only zk can be used as the registration center. Checking the code found that the SofaRpcAutoConfiguration class added the @ConditionalOnMissingBean annotation when it was injected into the registry processor implementation, resulting in only the processors of local, mesh, and zk being injected, and the processors of other registration centers were not injected. I do not know why to do this configuration? How do I modify it if I want to use the new version?
