SpringBoot 获取bean的公共类

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/***

@Component
public class SpringConfig implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if (SpringConfig.applicationContext == null) {
            SpringConfig.applicationContext = applicationContext;
        }
    }

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String name) {
        return applicationContext.getBean(name);
    }

    public static  T getBean(Class clazz) {
        return applicationContext.getBean(clazz);
    }

    public static  T getBean(String name, Class clazz) {
        return applicationContext.getBean(name, clazz);
    }
}

使用如下：

UserManagerClient userManagerClient = SpringConfig.getBean(UserManagerClient.class);
