模版工程搭建

用于记录基础功能的搭建-【持续更新】

基础工程创建

简单的过程不去记录，没有意义

• 最初的pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

</project>

• application.properties添加初始配置

#设置项目端口号 默认 8080
server.port=80
#设置项目访问前缀地址
server.servlet.context-path=/lulu

spring.application.name=lulu

logback配置

• 在application.properties中添加

#日志文件配置
logging.file.path=lulu-log
logging.file.name=${spring.application.name}

• 在resources文件夹中添加spring-logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true">
    <springProperty scope="context" name="APP_NAME" source="logging.file.name"/>
    <!-- 文件路径 -->
    <springProperty scope="context" name="FILE_PATH" source="logging.file.path"/>

    <!-- 日志文件输出 -->
    <appender name="FILE-LOG" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <!-- 文件路径 -->
        <file>${FILE_PATH}/${APP_NAME}-all.log</file>

</configuration>

解决跨域问题

• 新建config文件夹，添加CorsConfig配置

package com.tzcxyh.lulu.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.WebMvcConfigurer;
/**
 * @Description 全局跨域处理
 **/
@Configuration
public class CorsConfig implements WebMvcConfigurer {

    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.setAllowCredentials(true); // 允许cookies跨域
        //不同的springboot版本，2.4之后用这个
        corsConfiguration.addAllowedOriginPattern("*");
//        config.addAllowedOrigin("*");// #允许向该服务器提交请求的URI，*表示全部允许，在SpringMVC中，如果设成*，会自动转成当前请求头中的Origin
        corsConfiguration.addAllowedHeader("*");// #允许访问的头信息,*表示全部
        corsConfiguration.setMaxAge(18000L);// 预检请求的缓存时间（秒），即在这个时间段里，对于相同的跨域请求不会再预检了
        corsConfiguration.addAllowedMethod("OPTIONS");// 允许提交请求的方法类型，*表示全部允许
        corsConfiguration.addAllowedMethod("HEAD");
        corsConfiguration.addAllowedMethod("GET");
        corsConfiguration.addAllowedMethod("PUT");
        corsConfiguration.addAllowedMethod("POST");
        corsConfiguration.addAllowedMethod("DELETE");
        corsConfiguration.addAllowedMethod("PATCH");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }
}
