I found a place code wrong in nacos-client:2.0.2(有

也就是在nacosConfigService类中getConfigInner方法中使用了LocalConfigInfoProcessor.getFailover方法； 而这个方法在配置刷新之后，server端反馈给client端，最后调用spring的刷新机制，spring最后又会调用nacos-client的getConfig方法，在这里本来不应该再去请求server端了，因为之前nacos-client端已经请求过server，得到变更的配置并且更新仔本地文件中，我认为这里的LocalConfigInfoProcessor.getFailover(worker.getAgentName(), dataId, group, tenant) getFailover是废弃方法，它根本拿不到本地文件的最新配置，导致又请求了nacos-server，没有必要多做这一次请求，所以我觉得这里应该调用getSnapshot方法来获取本地最新的content然后直接返回

`private String getConfigInner(String tenant, String dataId, String group, long timeoutMs) throws NacosException { group = blank2defaultGroup(group); ParamUtils.checkKeyParam(dataId, group); ConfigResponse cr = new ConfigResponse();

cr.setDataId(dataId);
cr.setTenant(tenant);
cr.setGroup(group);
************************************** **************************************
**// i think this can not use getFailover,it need use getSnapshot.

//Otherwise, the local config will not be used here, and the server will always be requested. //This will cause the client to request the server twice when refreshing the configuration. //And there is no savefailover,so I guess the code here is your careless mistake.**

**String content = LocalConfigInfoProcessor.getFailover(worker.getAgentName(), dataId, group, tenant);**

if (content != null) {
    LOGGER.warn("[{}] [get-config] get failover ok, dataId={}, group={}, tenant={}, config={}",
            worker.getAgentName(), dataId, group, tenant, ContentUtils.truncateContent(content));
    cr.setContent(content);
    String encryptedDataKey = LocalEncryptedDataKeyProcessor
            .getEncryptDataKeyFailover(agent.getName(), dataId, group, tenant);
    cr.setEncryptedDataKey(encryptedDataKey);
    configFilterChainManager.doFilter(null, cr);
    content = cr.getContent();
    return content;
}

try {
    ConfigResponse response = worker.getServerConfig(dataId, group, tenant, timeoutMs, false);
    cr.setContent(response.getContent());
    cr.setEncryptedDataKey(response.getEncryptedDataKey());
    configFilterChainManager.doFilter(null, cr);
    content = cr.getContent();
    
    return content;`
