可以在Java定义自己配置的springmvc:
MyMvcConfig.java
package com.gong.springbootcurd.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.config.annotation.ViewControllerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; //@EnableWebMvc 接管springmvc @Configuration public class MyMvcConfig implements WebMvcConfigurer{ @Override public void addViewControllers(ViewControllerRegistry registry) { //浏览器发送gong请求会跳转到/templates/success.html页面 registry.addViewController("gong").setViewName("success"); } //所有的WebMvcConfigurer会一起起作用 //将组件注册到容器中 @Bean public WebMvcConfigurer webMvcConfigurer() { WebMvcConfigurer webMvcConfigurer = new WebMvcConfigurer(){ public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/").setViewName("index"); registry.addViewController("/index.html").setViewName("index"); } }; return webMvcConfigurer; } }
关键有三点:
(1)实现WebMvcConfigurer。
(2)用Configuration标识配置类。
(3)如果是public WebMvcConfigurer webMvcConfigurer() {...},则需要用@Bean标识。
