代码清洗大战：”abstract” classes should not have “public” constructors

Sonarqube给出了一个修饰符的使用建议，不得不说，sonarqube扫描的还是很全面的，真的是面面俱到，不放过任何一个细节！

————sonarqube 提示开始———–

Since abstract classes can’t be instantiated, there’s no point in their having public or internal constructors. If there is basic initialization logic that should run when an extending class instance is created, you can by all means put it in a constructor, but make that constructor private or protected.

Noncompliant Code Example

abstract class Base{    public Base() // Noncompliant, should be private or protected    {      //...    }}

Compliant Solution

abstract class Base{    protected Base()    {      //...    }}
