如何根据T的属性对List <T>进行排序？

public class T {
    private String attribute;

    public T(String attribute) {
        this.attribute = attribute;
    }

    public String getAttribute() {
        return attribute;
    }

    public void setAttribute(String attribute) {
        this.attribute = attribute;
    }
}

List<T> list = new ArrayList<>();
list.add(new T("value3"));
list.add(new T("value1"));
list.add(new T("value2"));

Collections.sort(list, new Comparator<T>() {
    @Override
    public int compare(T o1, T o2) {
        return o1.getAttribute().compareTo(o2.getAttribute());
    }
});
