这是我springboot连接 MongoDB 配置

spring:
      data:
        mongodb:
          uri: mongodb://192.168.1.143:9085/test,mongodb://192.168.1.144:9085/test,mongodb://192.168.1.145:9085/test

## 连接MongoDB 集群是出现 ##

java.lang.IllegalArgumentException: The connection string contains an invalid host 'mongodb://39.97.113.214:9085'. Reserved characters such as ':' must be escaped according RFC 2396. Any IPv6 address literal must be enclosed in '\[' and '\]' according to RFC 2732.

看到RFC 2732 有点懵逼，这是啥玩意，百度一下，发现这是“Internet 官方协议标准”（STD 1），给出的解释是在文字中IPv6 地址定义的文本表示与 URL 不直接兼容。因为两者使用了 “：”和“.” 作为分隔符。他们要求要在URL中使用文字IPv6地址，文字地址应包含在“\[”和“\]”字符中，详细解释请看**[1999年12月发布的URL中的文字IPv6地址的格式备忘录][1999_12_URL_IPv6]**

配置文件修改如下

spring:
      data:
        mongodb:
          uri: mongodb://[192.168.1.143:9085]/test,[192.168.1.144:9085]/test,[192.168.1.145:9085]/test

MongoDB源码也给出了示例的：

**
 * Represents a <a href="http://www.mongodb.org/display/DOCS/Connections">Connection String</a>. The Connection String describes the
 * hosts to be used and options.
 *
 * The format of the Connection String is:
 * <pre>
 * mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database.collection][?options]]
 * </pre>
 * <ul>
 * <li>{@code mongodb://} is a required prefix to identify that this is a string in the standard connection format.</li>
 * <li>{@code username:password@} are optional. If given, the driver will attempt to login to a database after
 * connecting to a database server. For some authentication mechanisms, only the username is specified and the password is not,
 * in which case the ":" after the username is left off as well</li>
 * <li>{@code host1} is the only required part of the connection string. It identifies a server address to connect to.
 * Support for Unix domain sockets was added in 3.7. Note: The path must be urlencoded eg: {@code mongodb://%2Ftmp%2Fmongodb-27017.sock}
 * and the {@code jnr.unixsocket} library installed.
 * </li>
 * <li>{@code :portX} is optional and defaults to :27017 if not provided.</li>
 * <li>{@code /database} is the name of the database to login to and thus is only relevant if the
 * {@code username:password@} syntax is used. If not specified the "admin" database will be used by default.</li>
 * <li>{@code ?options} are connection options. Note that if {@code database} is absent there is still a {@code /}
 * required between the last host and the {@code ?} introducing the options. Options are name=value pairs and the pairs
 * are separated by "&". For backwards compatibility, ";" is accepted as a separator in addition to "&",
 * but should be considered as deprecated.</li>
 * </ul>
 * An alternative format, using the mongodb+srv protocol, is:
 * <pre>
 * mongodb+srv://[username:password@]host[/[database][?options]]
 * </pre>
