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。二.springboot webmvc配置讲解
