启动SpringBoot报错Input length = 1问题及解决
启动SpringBoot报错Input length = 1问题
报错信息
maven-resources-plugin:3.2.0:resources (default-resources) on project jcy_interface_services: Input length = 1 -> [Help 1]
错误原因
maven,resource目录下配置文件的编码格式未设置。默认为GBK编码格式,需要在idea中设置编码为UTF-8。
解决办法
1.Settings---->File Encodings----> 凡是设计编码格式的选项全部修改为UTF-8
2.重启idea
3.重点注意:将原来配置文件中的注释删除,重新写上注释,否者还会出现乱码,无法运行。
解决一些Springboot启动报错问题
常见的两个原因
1、控制台信息如下
Connected to the target VM, address: ‘127.0.0.1:50617’, transport: ‘socket’
Disconnected from the target VM, address: ‘127.0.0.1:50617’, transport: ‘socket’
Process finished with exit code 0
原因是某个 .xml文件 被注释 释放即可,!
2、报错信息如下

1、首先得去看配置文件application.yml,pom.xml,程序入口类。这三个
2、把@EnableEurekaServer注解和关于eureka的配置都去掉 如果可以跑起来 就去引入jaxb-api;
注:从java9开始,模块化的概念使JAXB默认没有加载;jaxb-api是存在jdk中的,只是默认没有加载而已,我们需要手动引入。要问这个jaxb-api是什么作用 大家可以去百度一下
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
