JiaLiangoooo opened a new issue #1321:
URL: https://github.com/apache/dubbo-go/issues/1321
正在使用的版本是1.5.5rc1
目前正在尝试自定义loadbalance，但是balance里面会有一些自定义的参数.
```
type Compare func(invocation protocol.Invocation, invoker protocol.Invoker)
bool
func NewBalance(compare Compare) *Balance {
return &Balance{f: compare}
}
```
但是extension.SetLoadbalance支持的是`func () cluster.LoadBalance`
```
// SetLoadbalance sets the loadbalance extension with @name
// For example: random/round_robin/consistent_hash/least_active/...
func SetLoadbalance(name string, fcn func() cluster.LoadBalance) {
loadbalances[name] = fcn
}
// GetLoadbalance finds the loadbalance extension with @name
func GetLoadbalance(name string) cluster.LoadBalance {
if loadbalances[name] == nil {
panic("loadbalance for " + name + " is not existing, make sure
you have import the package.")
}
return loadbalances[name]()
}
```
所以有个疑问 为什么不使用`SetLoadbalance(name string, cluster.LoadBalance) `, 而使用`func
() cluster.LoadBalance` ?
