(Ljava/lang/String；)Ljava/lang/Integer； @65: areturn

IDEA中启动tomcat报错如下，导致项目启动失败：

根据(Ljava/lang/String;)Ljava/lang/Integer; @65: areturn排查报错原因

类型引用有问题

public static Integer getIndex(String week){
        String[] weekDays = { "周日", "周一", "周二", "周三", "周四", "周五", "周六" };//格式
        Integer index = 0;
        for(int i = 0 ;i
            if(week.equals(weekDays[i])){
                if(i == 0){//周日
                    return index = 7;
                }
                return index = i;
            }
        }
        return 0;
    }

把Integet改为int就可以了

public static int getIndex(String week){
        String[] weekDays = { "周日", "周一", "周二", "周三", "周四", "周五", "周六" };//格式
        int index = 0;
        for(int i = 0 ;i
            if(week.equals(weekDays[i])){
                if(i == 0){//周日
                    return index = 7;
                }
                return index = i;
            }
        }
        return 0;
    }
