Eclipse发现@Override的错误

Eclipse（from）发现@Override的错误

public class Class1 implements Comparable<Class1> {
...
@Override
public int compareTo(Class1 o) {

public类Class1实现了可比较的{
...
@凌驾
公共国际比较（1 o类）{

copmareTo（）具有标记：

Multiple markers at this line
    - The method compareTo(Class1 ) of type Class1 must override a superclass method
    - implements java.lang.Comparable<com.funshion.base.mc.entity.McImp>.compareTo

此行有多个标记
-Class1类型的方法compareTo（Class1）必须重写超类方法
-实现java.lang.Comparable.compareTo

第一条信息是错误的

由于@Override注释随Java 6一起到达。
