1.创建自定义TypeBuilder
```
package com.xxx.dubbo.TreeBuilder;
public class TreeBuilder implements TypeBuilder , Prioritized {
@Override
public boolean accept(Type type, Class<?> clazz) {
if (clazz == null) {
return false;
}
return Tree.class.isAssignableFrom(clazz);
}
@Override
public int getPriority() {
return -1;
}
@Override
public TypeDefinition build(Type type, Class<?> clazz, Map<Class<?>, TypeDefinition> typeCache) {
// balabala...
}
}
```
2. `META-INF`下创建`dubbo/internal/org.apache.dubbo.metadata.definition.builder.TypeBuilder`文件
```
tree=com.xxx.dubbo.TreeBuilder
```
