jenkins checkstyle：local variable hides a field

源代码：

1 2 3 4 5 6 7 8

//应用上下文 private static ApplicationContext applicationContext; public static void setApplicationContextValue(ApplicationContext applicationContext){     SpringContextUtil.applicationContext = applicationContext; } public static ApplicationContext getApplicationContext(){     return applicationContext; }

Jenkins上的checkstyle提示setApplicationContextValue()方法“hides a field”

该错误提示一般出现在变量的setter方法上，原因是：

It means you've got two different variables with the same name - myBoard. One of them is a field in your class. Another one is a local variable, that is, one that you've declared inside a method.

It's a bad idea to have two variables with the same name. It can make your code very confusing and difficult to maintain.

意思就是两个变量设置了相同的名称，一个是类变量，一个是方法内局部变量，解决方法：

1 2 3

public static void setApplicationContextValue(ApplicationContext applicationContext1){     SpringContextUtil.applicationContext = applicationContext1; }

将方法内形参名称改一下，与类变量区分开，比如applicationContext1。
