This article mainly shows you "how SpringBoot gets @ Service Bean classes in threads". The content is easy to understand and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how SpringBoot gets @ Service Bean classes in threads".

How to get the @ Service Bean class in a thread

This is suitable for Springboot projects without Spring configuration files, where it is much more convenient to get bean if you have a configuration file.

The following figure shows a Mybatis Mapper Bean that I declare with the @ Service annotation, which is usually used by the class under the Springboot scan configuration.

@ Autowired annotation dependency injection.

I need to use it in a thread now, but Springboot naturally can only scan its own things, the Runnable interface implemented by the thread.

We're starting to solve the problem now.

1. First, create a configuration class that inherits ApplicationContextAware to get ApplicationContext.

Use the getBean method inside to get the Bean class you want.

This way you can get the Bean class you want in the thread. It's quite a pit!

Get bean object in multithreading

Note: in multithreaded scenarios, bean objects cannot be obtained by using the default spring autoassembly, and the bean can be obtained directly from the context context.

Create a class

Implement the ApplicationContextAware interface

Package com.bond.match.utils;import org.springframework.beans.BeansException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.stereotype.Component;/** * Created with IntelliJ IDEA. * Date: 2018-1-11 0011 * Time: 13:20 * To change this template use File | Settings | File Templates. * / @ Componentpublic class ApplicationContextProvider implements ApplicationContextAware {private static ApplicationContext context; private ApplicationContextProvider () {} @ Override public void setApplicationContext (ApplicationContext applicationContext) throws BeansException {context = applicationContext;} public static T getBean (Class aClass) {return context.getBean (aClass);}} how to call in multithreading

.method () is the method name of the bean object

ApplicationContextProvider.getBean (AccountAssetService.class). Method () above is all the content of the article "how SpringBoot gets the @ Service Bean class in the thread". Thank you for reading!
