PMD規則之JavaBean Rules

·  BeanMembersShouldSerialize: If a class is a bean, or is referenced by a bean directly or indirectly it needs to be serializable. Member variables need to be marked as transient, static, or have accessor methods in the class. Marking variables as transient is the safest and easiest modification. Accessor methods should follow the Java naming conventions, i.e.if you have a variable foo, you should provide getFoo and setFoo methods.

翻譯  Bean成員應該是可序列化的：如果類是一個Java bean，或者被一個bean直接或間接地引用，它就需要序列化。類的成員變數需要被標記為transient,static,或具備存取方法。將變數標記為transient是最安全和最簡單的改動方法。存取方法應該遵循java命名規範，例如：如果有一個變數foo,應該提供getFoo()和setFoo()方法。

·  MissingSerialVersionUID: Classes that are serializable should provide a serialVersionUID field.

翻譯  缺少序列化版本ID：可序列化的類應該提供serialVersionUID域
