The difference between a timer and a quartz is three points:1. Different origins: The timer is provided directly by the JDK, the invocation is simple and rude, and no additional jar support is required. Quartz is not a JDK, it needs to introduce the appropriate jar package2. Ability difference: mainly in the control of time. A timer can be easily handled at a specific time, such as every Sunday morning at eight to remind the function of doing something needs to be quartz, so quartz control of ti

When a certain condition is reached, let the server send a message to the user, the number is more than one.
Basic idea: Linux timed scan, if you meet the conditions of the user, then send a text message.
But in order to prevent the interruption to the user, the request only during the daytime 8:00-20:00 send text messages, how to get to the daily time interval?
