安全性 - 数组直接存储

2022-01-17 00:00:00 sonarqube java findbugs

我什至提到:声纳违规:安全 - 阵列直接存储

我的代码是--->

    public final void setSelectedObjectsList(final ScheduleDTO[] selectedObjectsList) 
               //      Security - Array is stored directly    
               //The user-supplied array 'selectedObjectsList' is stored directly.      
{
            if (selectedObjectsList != null) {
                this.selectedObjectsList = selectedObjectsList.clone();
            } else {
                this.selectedObjectsList = null;
            }
        }

这已经在处理防御副本了，不知道为什么声纳就在函数参数处对我大喊大叫.

This is already taking care of defensive copy wonder why sonar is yelling at me right at function parameter.

这不是重复的声纳违规:安全 - 数组直接存储

再次感谢您的帮助和时间.

Again, Thank-you for your hyelp and time.

推荐答案

不确定 Sonar 的想法，但使用 clone() 进行防御性浅拷贝应该适用于数组，就像 Arrays.copyOf 和 System.arrayCopy().

Not sure what Sonar is thinking but defensive shallow copying with clone() should work fine for arrays, as would Arrays.copyOf and System.arrayCopy().

另一方面，由于您已经将数组称为列表:selectedObjectsList，您也可以将其设为实际列表并进行一些重构:

On the other hand, since you are already calling the array a list: selectedObjectsList, you could also make it an actual list and refactor a bit:

public final void setSelectedSchedules(List<ScheduleDTO> selectedSchedules) { this.selectedSchedules = selectedSchedules != null ? new ArrayList<ScheduleDTO>(selectedSchedules) : null; }
