一.配置springboot webmvc

1.springboot webmvc配置方式

通过继承 extends WebMvcConfigurerAdapter

@Configuration
    public class SpringMvcConfig extends  WebMvcConfigurerAdapter {

通过 implements WebMvcConfigurer

@Configuration
    public class SpringMvcConfig implements WebMvcConfigurer {

使用@EnableWebMvc 禁用默认配置 所有配置自己重写

@Configuration
    @EnableWebMvc
    public class SpringMvcConfig extends  WebMvcConfigurerAdapter {

2.springboot为springmvc提供了默认的配置 主要包括视图解析器、静态资源处理、类型转化器与格式化器、HTTP 消息转换器、静态主页的支持等。

3.EnableWebMvc注解问题

上面提到在使用 WebMvcConfigurer 扩展 Spring MVC 组件时，
    类上不能加 @EnableWebMvc 注解，原因是在加上该注解后，Spring MVC 的自动配置会失效，
    所有的东西都需要我们自动配置。
