报错内容：

原因：  
1、view name名称和path请求方法名相同,就等于让自己转发给自己，陷入死循环  
如：

@RequestMapping("/test")
        public String hello() {
        
        	
    		logger.trace("trace日志信息");
    		logger.debug("debug日志信息");
    	    logger.info("info日志信息");
    	    logger.warn("warn日志信息");
    	    logger.error("error日志信息");
    	    return "test";
        }

解决方法：修改返回值

2、返回值为空，但方法上没有`@ResponseBody`,会造成**缺省转发**  
如：

@RequestMapping("/test")
        public void hello() {
        
        	
    		logger.trace("trace日志信息");
    		logger.debug("debug日志信息");
    	    logger.info("info日志信息");
    	    logger.warn("warn日志信息");
    	    logger.error("error日志信息");
        }

解决方法：方法上增加`@ResponseBody`

最近再学日志框架，写测试时候我报这个错误，错误原因为第二个。

> 其实我只是加上异步后，不报错了，但具体原因我还是不理解，如果有明白的，评论或者私信告诉我一下，为啥我浏览器打http://localhost:82/test请求hello（）方法和`@ResponseBody`,注解有关系，直接敲不应该就是同步，然后报错找不到请求地址吗，怎么加上注解后，就不报错第二种错误了？
