springboot启动访问页面报错

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported

15个回答

method=RequestMethod.POST,只能post请求,get request not supported

查看你的controller中是不是指定了只能post访问接口,@PostMapping 。浏览器访问的页面的时候用的get所以不支持。要改成@GetMapping或者@RequestMapping

没有源码,怎么帮助呢。猜测get请求,controller里面没有get请求的方法。

你可以试试重新启动计算机。

连不上zookeeper,zookeeper荡掉了

springboot JPA的DAO报错NullPointerException
初次尝试搭建一个springboot框架,目前进行到JPA操作数据库这一步,但是继承了JpaRepository的UserDAO接口总是报空指针错误。 这是UserDAO: ``` @Repository public interface UserDAO extends JpaRepository<User,Long> { } ``` 这是测试类: ``` @Service public class Tes { @Autowired public UserDAO user; public void t() { User u = new User(); u.setAccount("ff"); u.setName("asufhua"); u.setPassword("123456"); u.setQx(1); user.save(u); } } ``` 这是Controller,在跳转首页之前,会调用Tes类往数据库里插一条记录: ``` @Controller public class HelloController { @RequestMapping("/") public String index() { new Tes().t(); return "index"; } } ``` 现在我每次进入首页,就会提示user.save处的空指针错误,好像这个DAO没有注入成功一样。 到现在折腾一下午了,我只能初步认定**这个DAO没有注入成功**,所以会NULL。 之前我找到的一个解决办法:把DAO和测试类放在同一个目录下就可以成功,可为什么分开放就不行? 我现在的目录结构是启动类在顶层,然后下面有dao/domain/web/service等多个子包。像这样分开放,会提示“expected at least 1 bean which qualifies as autowire candidate.” 于是我尝试在启动类加上路径扫描@MapperScan("xx.xx.dao"),就不报找不到bean的错,可以运行起来。 但是跑起来后,涉及到dao的操作又会报空指针错误。 我感觉spring怎么这么乱呢?启动类为什么不会扫描下面的子包?为什么注入后又是NULL? 哪位大侠帮帮我?

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

Python十大装B语法
Python 是一种代表简单思想的语言,其语法相对简单,很容易上手。不过,如果就此小视 Python 语法的精妙和深邃,那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点,并附上详细的实例代码。如能在实战中融会贯通、灵活使用,必将使代码更为精炼、高效,同时也会极大提升代码B格,使之看上去更老练,读起来更优雅。 1. for - else 什么?不是 if 和 else 才
