3. 启动类

package com.test.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

4. 配置文件

application.yml

server:
  websocket:
    max-text-message-buffer-size: 9MB
    max-binary-message-buffer-size: 9MB
application:
  target-url: https://xxx # 全局配置逻辑配置
spring:
  resources:
    static-locations: file:D:\\\\demo\\static\\ #对应服务器内映射的实际路径
  mvc:
    static-path-pattern: /static/**         #对应服务通过url访问静态文件夹时的前缀
  servlet:
    multipart:
      enabled: true
      max-file-size: 100MB
      max-request-size: 100MB
  jpa:
    database: MYSQL
  profiles:
    active: dev

application-dev.yml

server:
  port: 8081
#  ssl: # 证书自行配置
#    key-store: classpath:keystore.p12
#    key-store-password: 123456
#    key-password: 123456
#    key-store-type: PKCS12
#    key-alias: tomcat
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/demo?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=Asia/Shanghai
    username: root
    password: xxx

application-prod.yml与上述基本一致，部分配置自行调整

5. 配置类

package com.test.demo.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Data
@Configuration
@ConfigurationProperties(prefix = "application", ignoreUnknownFields = false)
public class ApplicationProperties {
    private String targetUrl;

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