springcloud2.x整合mybatis3+shardingsphere4.1.0&4.1.1 主从分离+服务治理

懒得按以前格式写了，纯粘代码

几点注意：
1、冲突问题，官网的配置未解决curator问题；（P.S. 最新版5.0.0α也没有处理好spring cloud 2.x+的问题，会造成no value bound，详见issue#8299

https://github.com/apache/shardingsphere/issues/8299

2、配置问题，官网的配置文档还停留在4.0.0的配置，看源码，配置的读取代码为

@Generated
    public void setOrchestration(Map<String, YamlCenterRepositoryConfiguration> orchestration) {
        this.orchestration = orchestration;
    }

可以看到接受的配置为Map<String, YamlCenterRepositoryConfiguration> orchestration，
所以配置应该是spring.shardingsphere.orchestration.名称.属性，而不是旧的spring.shardingsphere.orchestration.registry.xxx,这点具体可以看github的example
另：nacos居然只能做config center，配置为registry_center会报错，没有该枚举类型。有点尴尬，这样我还要额外再引入zk，那我何不一次性zk搞定呢。

spring.shardingsphere.orchestration.<String>.orchestration-type=registry_center,config_center
spring.shardingsphere.orchestration.<String>.instance-type=zookeeper
spring.shardingsphere.orchestration.<String>.server-lists=localhost:2181
spring.shardingsphere.orchestration.<String>.namespace=sharding-test
spring.shardingsphere.orchestration.<String>.props.overwrite=false

3、shardingsphere-ui运行的问题，官网提供的ui下载包有点问题，解压出来缺少jar，主要是缺胳膊少腿，如图，需要自己把jar包补充进去

具体代码如下（非生产代码，抽空额外做了个测试DEMO）
