航空后端部署1

1.新建项目

选择spring initializr

并装入lombok和spring web创建成功

2.向xml文件中添加依赖，以下是该项目添加的所有依赖

（1）版本号

<properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <spring-boot.version>2.3.7.RELEASE</spring-boot.version>
        <mybatis-plus.version>3.4.2</mybatis-plus.version>

3.加入跨域类实现前后端不同端口间的跨域

package com.zlw.hangkong.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;


@Configuration
public class GlobalWebMvcConfigurer implements WebMvcConfigurer {

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

    @Bean
    public CorsFilter corsFilter() {
        CorsConfiguration config = new CorsConfiguration();
        //允许所有域名进行跨域调用
        config.addAllowedOrigin("*");
        //允许跨越发送cookie
        config.setAllowCredentials(true);
        //放行全部原始头信息
        config.addAllowedHeader("*");
        //允许所有请求方法跨域调用
        config.addAllowedMethod("*");
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);
    }
}

4.一些请求报错格式文件的导入,（里面写了一些程序报错的和成功的方法）
