[Java] 在SoapUI里使用equals()方法时报java.lang.StackOverflowError

开始这样使用的时候一直报java.lang.StackOverflowError

        public boolean equals(Object o) {
            if(this == o)
                return true;
            if(o == null || getClass() != o.getClass())
                return false;
            HoldingInfo that = (HoldingInfo)o;
            return Objects.equals(performanceId, that.performanceId) && Objects.equals(name, that.name) && Objects.equals(weight, that.weight);
        }

        public int hashCode(){
            return Objects.hash(performanceId,name,weight);
        }

修改后就好了，上面这种写法当执行equal检查时，它将一次又一次的被它自己调用，直到堆栈溢出

        public boolean equals(Object o) {
            if(this.is(o))
                return true;
            if(o == null || getClass() != o.getClass())
                return false;
            HoldingInfo that = (HoldingInfo)o;
            return Objects.equals(performanceId, that.performanceId) && Objects.equals(name, that.name) && Objects.equals(weight, that.weight);
        }

        public int hashCode(){
            return Objects.hash(performanceId,name,weight);
        }
