在使用Spring配置定时任务时遇到异常，详细分析错误原因并给出解决方案。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

Spring 配置了一个定时器

<task:scheduled-tasks scheduler="task">

         <!--定时查询微信支付失败订单-->

         <task:scheduledref="purchase" method="wxDealPayResultTask" cron="0 00/2 * * ?" /><!--0 0 0/2 * * ? -->

         </task:scheduled-tasks>

 

在启动项目时，debug模式的时候报下面的错误，但是不影响功能正常使用，goolge了一下，在stackflow上发先了一个同样的问题，有人回答是这样：

There is noerror. Only a stack trace at debug level where Spring is trying to locate theright constructor for the login success handler (the default has 2 constructorsand only one will match the String provided as an argument, i.e. "/admin/login").You can ignore it or you can switch it off (debug logging at that level is notoften very helpful, and you probably wouldn't want it on in production).希望能给大家帮助

开发过程中发生了无法反序列化的问题,经过排查,是使用objectMapper进行反序列化转换的时候需要加一个支持反序列化的有参构造,方法体中什么也不用加,直接就是一个String类型的入参即可。每次错误都记录下来,做一个更好的回顾。

是前后端联调接口时，前端将数据封装好json给我时 序列化了两次， 导致后台我这边接收到后反序列化失败~

项目debug|no String-argument constructor/factory method to deserialize from String val
weixin_48118167的博客

400按照以往的经验，是前端的错误，一般来说就是前端发了莫名其妙的东西，后端没法解析，但是这次我觉得不是前端的问题，但是到底哪里出错了呢？1.由于是Jason字符串没法正常反序列化，可能是我的@PostMapping映射地址写错了，也许是映射到其他controller了上面了，但是经由检查，发现并未写错，因此这个可能性排除。不好说，不过检查了一下，发现没有问题（后来我试了一下，如果是注释错误，那么应该报500的错误，即服务器内部错误，而不是400）看了一下，没有问题，符合设计，那么问题就应该出在后端了。..
python requests发送post请求到java springboot报错no String-argument constructor/factory method to deserializ

spring 的参数解析器无法将传送过来的字符串解析为java对象，是因为python的json.dumps方法将json数据多包了一层。就是去掉json.dumps，直接传输data对象过去就行了。最近在学习python。

报错：None of the constructors found with defaultConstructorFinder on type AppService can be invoked with the available services and parameters.原因：在依赖注入（DI）或服务定位器中，特别是在某些框架或库（如 Spring、ASP.NET Core、或其他支持依赖注入的框架）中，表示框架无法找到合适的构造函数来实例化。导致因素：1、重复注入。

这个问题太坑了 花费了半天时间在定位排查 最后发现是自己对json的不理解导致的 网上查了有很多不同的回答 估计是各种情况都会报这个吧 后续再深入研究 出现问题的原因是：json格式不对 要么是int类型加上了双引号 要么是给数组加上了双引号 总之出现这个问题的时候先对json进行格式化 或者放到postman里面 就知道格式哪里不对了 修改格式后问题就解决了 坑死自己了 在做MD5加密的时候 还...
