获取spring中所有的bean名称

  前置条件：所在bean实现

ApplicationContextAware接口 配置一个

private Set
    
      beanNames=new HashSet<>(500); 容器 实现过程：
    

@Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    for(String beanName:applicationContext.getBeanDefinitionNames()){
      beanNames.add(beanName);   } }

@GetMapping("obtain.bean.names") public R obtainBeanNames(){
    return R.success(beanNames); } 获取：{
  {url}}/obtain.bean.names
