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。
