在SpringBoot项目中遇到MongoDB连接超时的问题，日志显示尝试连接localhost而不是配置的IP地址。查阅官网资料后发现，SpringBoot默认配置会尝试连接localhost。为解决此问题，需要自定义MongoDB的连接配置文件。

springboot配置mongodb配置ip地址了连接超时，托日志发现一直链接的是localhost，去官网了解了一波，原来默认配置使用的是localhost请求mongodb，重写连接mongo配置文件

@Component
public class MongoClass {
    @Value("${host}")
    private String host;
    @Value("${port}")
    private String port;
    @Value("${userdatabase}")
    private String userdatabase;
    @Value("${usename}")
    private String usename;
    @Value("${password}")
    private String password;

    @Bean
    @ConditionalOnMissingBean(MongoClient.class)
    public MongoClient getMongodbClients() {
        List<ServerAddress> addresses = new ArrayList<ServerAddress>();
        String[] hosts = host.split(";");
        if (hosts == null || hosts.length < 1) {
            return null;
        }
        for (int i = 0; i < hosts.length; i++) {
            System.out.println("hosts==================" + hosts[i]);
            int portNum = Integer.parseInt(port);
            ServerAddress address = new ServerAddress(hosts[i], portNum);
            addresses.add(address);

        }
        MongoCredential credential = null;
        if (StringUtils.isNotEmpty(usename) && StringUtils.isNotEmpty(password)) {
            // credential = MongoCredential.createMongoCRCredential(usename, userdatabase, password.toCharArray());

            credential = MongoCredential.createCredential(usename, userdatabase, password.toCharArray());

            MongoClient client = new MongoClient(addresses, Arrays.asList(credential));
            return client;

        }
        MongoClient client = new MongoClient(addresses);

        return client;
    }

}
