一.配置springboot webmvc

1.springboot webmvc配置方式

   通過繼承 extends WebMvcConfigurerAdapter

@Configuration
public class SpringMvcConfig extends  WebMvcConfigurerAdapter {

   通過 implements WebMvcConfigurer 

@Configuration
public class SpringMvcConfig implements WebMvcConfigurer {
 

  使用@EnableWebMvc 禁用預設配置 所有配置自己重寫

@Configuration
@EnableWebMvc
public class SpringMvcConfig extends  WebMvcConfigurerAdapter {

2.springboot為springmvc提供了預設的配置 主要包括檢視解析器、靜態資源處理、型別轉化器與格式化器、HTTP 訊息轉換器、靜態主頁的支援等。

3.EnableWebMvc註解問題

上面提到在使用 WebMvcConfigurer 擴充套件 Spring MVC 元件時，
類上不能加 @EnableWebMvc 註解，原因是在加上該註解後，Spring MVC 的自動配置會失效，
所有的東西都需要我們自動配置。
