# 问题

back:springBoot

# Spring application context not configured for this file

出现这个意思是新建的Spring配置文件没有被加入到spring里面

p

# 将工程打包成jar包运行，就报java.io.FileNotFoundException: class path resource错误

原因是因为传入的参数是File，在IntelliJ IDEA里运行时，billingconfig-file.xml是个独立的文件，可以被File访问到， 但是将工程打包成jar包运行，billingconfig-file.xml被封装到jar包中了，不是一个独立文件了，此时肯定无法使用File访问到。
了解了原因，我们可以将传递unmarshaller.unmarshal()方法的参数从File变成InputStream就可以了

将unmarshaller.unmarshal(resourceFile.getFile());
// 修改为：
unmarshaller.unmarshal(resourceFile.getInputStream());

# Springboot读取application.properties中文乱码

解决方案:
1、在IDEA环境下：File -> Settings -> Editor -> File Encodings
将Properties Files (*.properties)下的Default encoding for properties files设置为UTF-8，将Transparent native-to-ascii conversion前的勾选上

注意：做了上面操作后，一定要重新创建 application.properties 才有效！(即重新录入中文信息)

# 实现了WebMvcConfigurer仍然没有执行addInterceptors,导致拦截器不生效

代码中有WebMvcConfigurationSupport的继承类，SpringBoot会做如果有WebMvcConfigurationSupport就不会加载WebMvcConfigurer

  • 可在WebMvcConfigurationSupport实现类中重写addInterceptors
  • 可调整该继承为实现WebMvcConfigurer
