springboot在多线程中注入对象

springboot多线程，线程类无法实现自动注入需要的bean，可以通过工具类获取需要的bean

@Component
public class ApplicationContextProvider implements ApplicationContextAware {
/**
* 上下文对象实例
*/
private static ApplicationContext applicationContext;

@SuppressWarnings("static-access")
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}

/**
* 获取applicationContext
*
* @return
*/
public static ApplicationContext getApplicationContext() {
return applicationContext;
}

/**
* 通过name获取 Bean.
*
* @param name
* @return
*/
public static Object getBean(String name) {
return getApplicationContext().getBean(name);
}

/**
* 通过class获取Bean.
*
* @param clazz
* @param <T>
* @return
*/
public static <T> T getBean(Class<T> clazz) {
return getApplicationContext().getBean(clazz);
}

/**
* 通过name,以及Clazz返回指定的Bean
*
* @param name
* @param clazz
* @param <T>
* @return
*/
public static <T> T getBean(String name, Class<T> clazz) {
return getApplicationContext().getBean(name, clazz);
}

}

public class MyThread implements Runnable {

public UserService userService;

public MyThread (){
this.userService= (UserService ) ApplicationContextProvider.getBean("userService");

//或者

//this.userService= ApplicationContextProvider.getBean(UserService .class);
}

@Override
public void run() {

}

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService= userService;
}
}
