Another possibility is to force Spring to create a new prototype instance when every call on prototype’s method. To achieve this, you need to modify the prototype bean and set itsproxy mode. You can do this by
Spring MVC框架简化了V和C之间的数据交互过程 Spring Boot: boot : 启动 支持Spring Boot框架的项目内置了很多配置,这些配置都是大部分框架的常规配置,当我们使用这些框架时,就免去了那些繁琐的配置。除了这些配置之外,还包含了一些约定:例如static文件夹存放静态资源等。回到...
