非spring的 jar 包里创建一个bean，但是不自动引入（代码库）

场景：sdk 里获取spring 的bean

 

1、先新建一个类

package com.yonyou.yht.bean;

import com.yonyou.iuap.yms.session.YmsSessionMangager;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class YmsSessionMangagerYhtApp implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @Override
    public synchronized void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        YmsSessionMangagerYhtApp.applicationContext = applicationContext;
    }

    public static YmsSessionMangager getYmsSessionMangagerBean() {
        if (applicationContext == null) {
            return null;
        }
        return applicationContext.getBean(YmsSessionMangager.class);
    }
}

 

2、SDK里调用的时候

private static Map<String, String> getSession2RemoteStorage(String token) {
   try {
      YmsSessionMangager bean = YmsSessionMangagerYhtApp.getYmsSessionMangagerBean();
      if (bean == null) {
         return null;
      }
      return bean.getSession2RemoteStorage(token);
   } catch (Exception e) {
      logger.error("UserCenter saveSession2Storage error, [msg = {}]", e.getMessage(), e);
      return null;
   }
}

 

3、项目里调用的时候，需要注入这个bean

@Bean("ymsSessionMangagerYhtApp")
public YmsSessionMangagerYhtApp ymsSessionMangagerYhtApp() {
    return new YmsSessionMangagerYhtApp();
}
