springboot-访问路径强制使用后缀

springboot 版本号：2.2.5.RELEASE

对一步：添加后缀匹配规则

/**
     * 设置匹配后缀请求规则
     * @param dispatcherServlet
     * @return
     */@Beanpublic ServletRegistrationBeanservletRegistrationBean(DispatcherServlet dispatcherServlet){
        ServletRegistrationBean<DispatcherServlet> servletServletRegistrationBean=newServletRegistrationBean(dispatcherServlet);
        servletServletRegistrationBean.addUrlMappings("*.do","*.action");return servletServletRegistrationBean;}

第二步：启用规格参数设置

spring:
  mvc:
    contentnegotiation:
      favor-path-extension:true
    pathmatch:
      use-suffix-pattern:true
      use-registered-suffix-pattern:true

以上两步完成后所有访问路径后面必须添加相应后缀规则才能正确访问
