1、创建普通maven项目

• 右键点击父项目

• New/Module…

• 创建普通maven项目

• 填写项目信息，点击Finish按钮

2、修改pom.xml文件如下

根据项目的需要，把不需要的依赖注释即可：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>
</project>

3、创建配置文件application.properties

# 应用名称
spring.application.name=server-zg6-es

# 应用服务 WEB 访问端口
server.port=8103


#下面这些内容是为了让MyBatis映射
#指定Mybatis的Mapper文件
mybatis.mapper-locations=classpath:mappers/*xml
#指定Mybatis的实体目录
mybatis.type-aliases-package=com.shenmazg6.pojo

# 数据库驱动：
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
# 数据源名称
spring.datasource.name=defaultDataSource
# 数据库连接地址
spring.datasource.url=jdbc:mysql://localhost:3306/db_shop_2005a?autoReconnect= true&useUnicode= true&characterEncoding=utf8&serverTimezone=Asia/Shanghai

# 数据库用户名&密码：
spring.datasource.username=root
spring.datasource.password=123456

# SQL调试日志
logging.level.com.shenmazg6.mapper=debug

# 逻辑删除配置
mybatis-plus.global-config.db-config.logic-delete-field=deleted
mybatis-plus.global-config.db-config.logic-not-delete-value=0
mybatis-plus.global-config.db-config.logic-delete-value=1

# Nacos帮助文档: https://nacos.io/zh-cn/docs/concepts.html
# Nacos认证信息
spring.cloud.nacos.discovery.username=nacos
spring.cloud.nacos.discovery.password=1912@a
# Nacos 服务发现与注册配置，其中子属性 server-addr 指定 Nacos 服务器主机和端口
spring.cloud.nacos.discovery.server-addr=8.142.83.78:8848
# 注册到 nacos 的指定 namespace，默认为 public
spring.cloud.nacos.discovery.namespace=public
spring.cloud.nacos.discovery.group=zhouhaijun

4、创建启动类

package com.shenmazong2005.es;

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

@SpringBootApplication
public class ElasticSearchApplication {

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

5、创建资源目录

• static目录

• templates目录

6、创建测试类

package com.shenmazong2005.es;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class TestEsApplication {

    @Test
    void testCreateIndex() {
        System.out.println("testCreateIndex...");
    }

}

6、启动项目即可
