- 方法详细资料
  - getUrl
```
org.apache.dubbo.common.URL getUrl()
```
    Get the configurator url.
    
    返回:
    
    configurator url.
  - configure
```
org.apache.dubbo.common.URL configure(org.apache.dubbo.common.URL url)
```
    Configure the provider url.
    
    参数:
    
    url - - old provider url.
    
    返回:
    
    new provider url.
  - toConfigurators
```
static Optional<List<Configurator>> toConfigurators(List<org.apache.dubbo.common.URL> urls)
```
    Convert override urls to map for use when re-refer. Send all rules every time, the urls will be reassembled and calculated URL contract:
    
    override://0.0.0.0/...( or override://ip:port...?anyhost=true)¶1=value1... means global rules (all of the providers take effect)
    
    override://ip:port...?anyhost=false Special rules (only for a certain provider)
    
    override:// rule is not supported... ,needs to be calculated by registry itself
    
    override://0.0.0.0/ without parameters means clearing the override
    参数:
    
    urls - URL list to convert
    
    返回:
    
    converted configurator list
  - compareTo
```
default int compareTo(Configurator o)
```
    Sort by host, then by priority 1. the url with a specific host ip should have higher priority than 0.0.0.0 2. if two url has the same host, compare by priority value；
