When something has a Runnable interface, it simply means that it has a run( ) method, but there’s nothing special about that?it doesn’t produce any innate threading abilities, like those of a class inherited from Thread. So to produce a thread from a Runnable object, you must create a separate Thread object as shown in this example, handing the Runnable object to the special Thread constructor. You can then call start( ) for that thread, which performs the usual initialization and then calls run( ).
如：raorao写的ToSendMailOfGoalAction.java中的：
ToSendMailOfThread toSendMailOfThread = new ToSendMailOfThread(userInfoList,articleInfo,goalID,userNameOfWriteDiary);
Thread t = new Thread(toSendMailOfThread);
t.start();
