- 方法详细资料
  - getRootPath
```
String getRootPath(EndpointId endpointId)
```
    Resolve the root path for the specified endpointId.
    参数:
    endpointId - the id of an endpoint
    返回:
    the path of the endpoint or null if this mapper doesn't support the given endpoint ID
  - useEndpointId
```
@Deprecated
static PathMapper useEndpointId()
```
    已过时。
    since 2.1.0 in favor of getRootPath(List, EndpointId) with a null list
    Returns an PathMapper that uses the endpoint ID as the path.
    返回:
    an PathMapper that uses the lowercase endpoint ID as the path
  - getRootPath
```
static String getRootPath(List<PathMapper> pathMappers,
                          EndpointId endpointId)
```
    Resolve the root path for the specified endpointId from the given path mappers. If no mapper matches then the ID itself is returned.
    参数:
    pathMappers - the path mappers (may be null)
    endpointId - the id of an endpoint
    返回:
    the path of the endpoint
