1. QuorumPeer.run() 核心流程执行流程进行选举（选举过程与结果）

 @Override
    public void run() {
   
        setName("QuorumPeer" + "[myid=" + getId() + "]" +
                cnxnFactory.getLocalAddress());

        LOG.debug("Starting quorum peer");
        try {
   
            jmxQuorumBean = new QuorumBean(this);
            MBeanRegistry.getInstance().register(jmxQuorumBean, null);
            for(QuorumServer s: getView().values()){
   
                ZKMBeanInfo p;
                if (getId() == s.id) {
   
                    p = jmxLocalPeerBean = new LocalPeerBean(this);
                    try {
   
                        MBeanRegistry.getInstance().register(p, jmxQuorumBean);
                    } catch (Exception e) {
   
                        LOG.warn("Failed to register with JMX", e);
                        jmxLocalPeerBean = null;
                    }
                } else {
   
                    p = new RemotePeerBean(s);
                    try {
   
                        MBeanRegistry.
