在SpringBoot3环境下导入黑马点评后端项目

创建空项目。
在设置中配置Maven。参考：IDEA配置Maven教程（超详细版~)_idea maven配置教程-CSDN博客
将资料中提供的项目源码放入创建的空项目路径下。
导入项目模块。

更改项目配置。src/main/resources/application.yml 注：原文件为application.yaml，我习惯.yml文件，所以这里是application.yml。

更改Mysql数据库驱动类名。

spring:
  datasource:
#    driver-class-name: com.mysql.jdbc.Driver
    driver-class-name: com.mysql.cj.jdbc.Driver

更改Mysql数据库密码。

spring:
  datasource:
    password: 1234567

更改Redis主机IP。

#spring:
#  redis:
#    host: 192.168.150.101
spring:
  data:
    redis:
      host: Redis服务主机IP
# 注：多了一级data

更改Redis主机密码。

spring:
  data:
    redis:
      password: 服务密码

application.yml：

server:
  port: 8081
spring:
  application:
    name: hmdp
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/hmdp?useSSL=false&serverTimezone=UTC
    username: root
    password: Mysql密码
  jackson:
    default-property-inclusion: non_null # JSON处理时忽略非空字段
  data:
    redis:
      host: 提供Redis服务的主机IP
      port: 6379
      password: Redis密码
      lettuce:
        pool:
          max-active: 10
          max-idle: 10
          min-idle: 1
          time-between-eviction-runs: 10s
mybatis-plus:
  type-aliases-package: com.hmdp.entity # 别名扫描包
logging:
  level:
    com.hmdp: debug

更改Maven 项目的核心配置文件pom.xml。
