Introduction to the newman framework in the Java class library

Newman framework introduction Newman is a class library framework for Java programming language, which aims to provide developers with a convenient way to build and manage task scheduling systems.It provides a series of categories and methods to make task scheduling easier and efficient. Main features and functions: 1. Task scheduling management: The Newman framework provides a reliable task scheduling management mechanism that allows developers to create and configure different types of tasks and specify their scheduling rules.In this way, developers can easily create timing tasks, delayed tasks or cycle tasks. 2. Flexible configuration options: Newman allows users to flexibly configure the task through annotations or configuration files.Developers can use annotations to define the attributes of tasks, such as scheduling rules, task names, execution methods, etc.In addition, the configuration information can be stored in the configuration file for easy modification and management. 3. Multi -threaded support: The Newman framework is based on the Java multi -threaded mechanism, allowing tasks to perform in independent threads.This allows some complicated tasks to perform parallel and improve task execution efficiency. 4. Error processing mechanism: The Newman framework provides a strong set of error handling mechanisms to ensure the stability and reliability of task execution.Developers can define the error processor for handling abnormal conditions in the execution of tasks, and handle it accordingly as needed. Here are some examples of using the Newman framework: 1. Create a simple timing task: import com.newman.scheduler.Newman; import com.newman.scheduler.Scheduler; public class MyTask { @Newman(jobName = "myTask", cronExpression = "0 0/5 * * * ?") public void execute() { // Todo: The logic of task execution } } public class Main { public static void main(String[] args) { Scheduler scheduler = new Scheduler(); scheduler.schedule(MyTask.class); } } In the above example, we define a timing task called "MyTask" by annotating, and the scheduling rules are executed every 5 minutes.Then, we use the `Scheduler` class to create a task scheduler and call the` Schedule` method to start the task. 2. Create a delay task: import com.newman.scheduler.Newman; import com.newman.scheduler.Scheduler; public class MyTask { @Newman(jobName = "myTask", initialDelay = 5000) public void execute() { // Todo: The logic of task execution } } public class Main { public static void main(String[] args) { Scheduler scheduler = new Scheduler(); scheduler.scheduleDelay(MyTask.class); } } In the above example, we define a delayed task called "MyTask" by annotating, and the initial delay time is 5000 milliseconds (5 seconds).Then, we use the `Scheduler` class to create a task schedule and call the` scheduledlay` method to start the task. This is just a small portion of functional examples provided by the Newman framework. This framework also provides many other functions, such as cycle tasks, task status management, and task cancellation.Using the Newman framework, developers can easily build and manage task scheduling systems to improve development efficiency and application reliability.
