来个大佬看看,这个错误第二次了,第一次的时候我发现了是jar包的版本太低,导入版本的Jar包,问题解决了,现在又出现了这个问题,求大佬帮忙

2个回答

还是jar包问题,可能是多个版本冲突、版本低、缺包;具体要看配置才知道

qq_43764144
qq_43764144 我之前导入的3.2的,我前面的3.2的没有删除,后面直接导入4.2的这样的会冲突么。我前面的编写的手动代理没有问题,但是就是编写这个半动态代理就错了

这个大多是因为静态初始化导致的问题,你可以查查你的代码中读取相关配置文件的时候,读取的路劲是不是正确的

weixin_37486553
燕双嘤嘤 回复qq_43764144: 这个不就是初始化的时候,要创建bean,如果配置文件中的bean配置映射读取失败就会有这个问题,可能是配置文件找不到,也可能是找到了配置文件,但是里面的配置有错误,路劲指定的不对

源码阅读(19):Java中主要的Map结构——HashMap容器(下1)
HashMap容器从字面的理解就是,基于Hash算法构造的Map容器。从数据结构的知识体系来说,HashMap容器是散列表在Java中的具体表达(并非线性表结构)。具体来说就是,利用K-V键值对中键对象的某个属性(默认使用该对象的“内存起始位置”这一属性)作为计算依据进行哈希计算(调用hashCode方法),然后再以计算后的返回值为依据,将当前K-V键值对在符合HashMap容器构造原则的基础上,放置到HashMap容器的某个位置上,且这个位置和之前添加的K-V键值对的存储位置完全独立,不一定构成连续的存储

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,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
