本文主要是介绍15.web开发-SpringMVC自动配置概览,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
Spring Boot provides auto-configuration for Spring MVC that works well with most applications.(大多场景我们都无需自定义配置)
The auto-configuration adds the following features on top of Spring’s defaults:
- Inclusion of
ContentNegotiatingViewResolver
andBeanNameViewResolver
beans.
- 内容协商视图解析器和BeanName视图解析器
- Support for serving static resources, including support for WebJars (covered later in this document)).
- 静态资源(包括webjars)
- Automatic registration of
Converter
,GenericConverter
, andFormatter
beans.
- 自动注册
Converter,GenericConverter,Formatter
- Support for
HttpMessageConverters
(covered later in this document).
- 支持
HttpMessageConverters
(后来我们配合内容协商理解原理)
- Automatic registration of
MessageCodesResolver
(covered later in this document).
- 自动注册
MessageCodesResolver
(国际化用)
- Static
index.html
support.
- 静态index.html 页支持
- Custom
Favicon
support (covered later in this document).
- 自定义
Favicon
- Automatic use of a
ConfigurableWebBindingInitializer
bean (covered later in this document).
- 自动使用
ConfigurableWebBindingInitializer
,(DataBinder负责将请求数据绑定到JavaBean上)
If you want to keep those Spring Boot MVC customizations and make more MVC customizations (interceptors, formatters, view controllers, and other features), you can add your own @Configuration
class of type WebMvcConfigurer
but without @EnableWebMvc
.
不用@EnableWebMvc注解。使用 @Configuration
+ WebMvcConfigurer
自定义规则
If you want to provide custom instances of RequestMappingHandlerMapping
, RequestMappingHandlerAdapter
, or ExceptionHandlerExceptionResolver
, and still keep the Spring Boot MVC customizations, you can declare a bean of type WebMvcRegistrations
and use it to provide custom instances of those components.
声明 WebMvcRegistrations
改变默认底层组件
If you want to take complete control of Spring MVC, you can add your own @Configuration
annotated with @EnableWebMvc
, or alternatively add your own @Configuration
-annotated DelegatingWebMvcConfiguration
as described in the Javadoc of @EnableWebMvc
.
使用 @EnableWebMvc+@Configuration+DelegatingWebMvcConfiguration 全面接管SpringMVC
