Spring Boot 中使用WebMvcConfigurer

package com.lt.mify.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class DefaultView implements WebMvcConfigurer {
  /**
  *視圖跳轉，初始化頁面跳轉
  * 如http://127.0.0.0.1:8080默認調到login.html頁面
  */
   @Override
 public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("login/login.html");
        registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
    }

    /**
     * 跨域支持
     */
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowCredentials(true)
                .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
                .maxAge(3600);
    }


}
