想问下 为什么在3.x内比较的时候要忽略id属性, 这是出于什么原因考虑的? 在2.x内最新版也是没有忽略id属性的

主要是`AbstractConfig#equals`方法没有看`parameters`的参数
https://github.com/apache/dubbo/blob/3.0/dubbo-common/src/main/java/org/apache/dubbo/config/context/AbstractConfigManager.java#L161-L167
```java
if (!(config instanceof ReferenceConfigBase || config instanceof ServiceConfigBase)) {
for (AbstractConfig value : configsMap.values()) {
if (value.equals(config)) {
return (T) value;
}
}
}
```
[AbstractConfig#equals](https://github.com/apache/dubbo/blob/3.0/dubbo-common/src/main/java/org/apache/dubbo/config/AbstractConfig.java#L959-L983) 方法列表没有`getParameters()`
```java
public boolean equals(Object obj) {
if (obj == null || obj.getClass() != this.getClass()) {
return false;
}
if (obj == this) {
return true;
}
for (Method method : getAttributedMethods()) {
// ignore compare 'id' value
if ("getId".equals(method.getName())) {
continue;
}
try {
Object value1 = method.invoke(this);
Object value2 = method.invoke(obj);
if (!Objects.equals(value1, value2)) {
return false;
}
} catch (Exception e) {
throw new IllegalStateException("compare config instances failed", e);
}
}
return true;
}
```
[MethodUtils.isGetter](https://github.com/apache/dubbo/blob/3.0/dubbo-common/src/main/java/org/apache/dubbo/common/utils/MethodUtils.java#L77)判断返回类型是Map的方法不是get

因为 id 在大部分是时候是自动生成的，而 equal 比较的时候是比较的属性
