SpringBoot扩展自定义配置

一.在默认SpringMVC配置基础上扩展自定义配置

1）、创建一个配置类，继承WebMvcConfigurerAdapter

2）、添加@Configuration注解

3）、例如自定义一个视图解析：

@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {
    //打开成功页
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        registry.addViewController("/zhq").setViewName("success");
    }
   //打开主页
   @Bean
    public WebMvcConfigurerAdapter  toIndex(){
        WebMvcConfigurerAdapter  adpter=new WebMvcConfigurerAdapter(){
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
            }
        };
        return adpter;
    }

说明：其中WebMvcConfigurerAdapter中定义了扩展自定义配置的接口,要添加配置重写方法就像了

public abstract class WebMvcConfigurerAdapter implements WebMvcConfigurer {
    public WebMvcConfigurerAdapter() {
    }

    public void configurePathMatch(PathMatchConfigurer configurer) {
    }

    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    }

    public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
    }

    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    }

    public void addFormatters(FormatterRegistry registry) {
    }

    public void addInterceptors(InterceptorRegistry registry) {
    }

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
    }

    public void addCorsMappings(CorsRegistry registry) {
    }

    public void addViewControllers(ViewControllerRegistry registry) {
    }

    public void configureViewResolvers(ViewResolverRegistry registry) {
    }

    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
    }

    public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers) {
    }

    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
...

二.全盘接管SpringMVC配置

1）、只需要再添加@EnableWebMvc即可,然后自定义需要添加的组件

@EnableWebMvc
@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        registry.addViewController("/zhq").setViewName("success");
    }
...
