1. Create a project
2. Modify the encoding format to UTF-8
3. Check or configure the code auto-completion function
4. Check or configure automatic package import
5. Check or configure Maven, you can use domestic warehouse mirroring
6. IDEA recognizes the Maven project: In the Notifications view, it will prompt Load Maven Project, just click it.
7. Turn on hot deployment
a. Confirm that dependencies have been referenced in pom.xml
!-- dependencies 标签下检查是否引⼊spring-boot-devtools依赖，如果没有加⼊如下引⽤ -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>b. Check the following options in the corresponding column of Settings
8. Select YAML or Properties file
In the project, YAML and Properties files can be selected as configuration files (can exist at the same time), and the application.yml file is used here
# application.yml
# Spring 全局配置
spring:
application:
name: java_forum # 项目名称
output:
ansi:
enabled: ALWAYS # 控制台输出彩色日志
datasource:
url: jdbc:mysql://127.0.0.1:3306/java_forum?characterEncoding=utf8&useSSL=false # 数据库连接串
username: root # 数据库用户名
password: # 数据库密码
driver-class-name: com.mysql.jdbc.Driver # 数据库驱动类
mvc:
pathmatch:

# JSON序列化配置
jackson:
date-format: yyyy-MM-dd HH:mm:ss # 日期格式
default-property-inclusion: NON_NULL # 不为null时序列化
server:
port: 58080 # 修改Tomcat的默认端口号
# 日志配置
logging:
pattern:
date format: yyyy-MM-dd HH:mm:ss
level:
root: info # 默认日志级别
com.example.demo: debug # 指定包的日志级别
file:
path: D:\git_file\java_forum # 日志保存目录
# mybatis 相关配置，单独配置，顶格写
mybatis:
mapper-locations: classpath:mapper/**/*.xml # 指定 xxxMapper.xml的扫描路径
# 项目自定义相关配置
java-forum:
login:
url: sign-in.html # 未登录状况下强制跳转页面
index: # 首页配置节点
board-num: 9 # 首页中显示的版块个数9. Environmental testing
Create a controller package at the same level as JavaForumApplication.java, and create TestController.java under the controller package
// Controller注解，返回的对象⽤JSON形式表⽰
@RestController
// 指定测试根路径映射地址前缀
@RequestMapping("/test")
public class TestController {
@ApiOperation(("测试打印"))
@GetMapping("/hello")
public String hello(){
return "hello";
}
}10. Test Maven
Add the following configuration under the properties tag of the pom.xml file:
<?xml version="1.0" encoding="UTF-8"?>

11. In the Maven column, double-click the package to run the command
Use a browser to access: http://localhost:58080/test/hello , and the following results show that the operation is successful.
12. Push to the remote warehouse through Git
View the current status and list the files added after unmodification: git status
Add the modified file to the temporary storage area, run git status again, and the above file will turn green: git add .
Submit to the local warehouse: git commit -m 'remarks'
Push to remote warehouse: git push origin master
