前言：记录下安装过程以便下次有需要无需百度！

PS：这里用的是 Jdk 17.0.4.1，并且用的是 undertow 容器

如果是 Jdk 1.8 升级到 jdk 17 的话 pom.xml 文件需要调整

<properties>
        <!--   jdk   -->
        <java.version>17</java.version>
        <!--   jaxb   -->
        <jaxb.version>2.4.0-b180830.0359</jaxb.version>
</properties>

<!--   jdk 9 or higher no javax jar   -->
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>${jaxb.version}</version>
</dependency>

1、修改 pom.xml 里面的 properties

spring boot 2.5.5 pom.xml 里面的 properties
PS：这里没有 dubbo 的问题在于 引用了 spring-cloud-starter-dubbo

<properties>
  <!--   spring-boot   -->
  <spring-boot.version>2.5.5</spring-boot.version>
  <!--   spring-cloud   -->
  <spring-cloud.version>2020.0.4</spring-cloud.version>
  <!--   spring-cloud-alibaba   -->
  <spring-cloud-alibaba.version>2021.1</spring-cloud-alibaba.version>
</properties>

spring boot 3.0.5 pom.xml 里面的 properties

<properties>
  <!--   spring-boot   -->
  <spring-boot.version>3.0.5</spring-boot.version>
  <!--   spring-cloud   -->
  <spring-cloud.version>2022.0.2</spring-cloud.version>
  <!--   spring-cloud-alibaba   -->
  <spring-cloud-alibaba.version>2022.0.0.0-RC1</spring-cloud-alibaba.version>
  <!--   dubbo   -->
  <dubbo.version>3.2.0</dubbo.version>
</properties>

2、包引用的替换

旧 dubbo 包的应用

<!-- dubbo -->
<dependency>
  <groupId>com.alibaba.cloud</groupId>
  <artifactId>spring-cloud-starter-dubbo</artifactId>
</dependency>

dubbo 3.0 的引用
PS：这里 dubbo 包之所有排除 fastjson2 是因为外面有单独的引用并且版本是不一样的

<!-- dubbo-spring-boot-starter -->
<dependency>
  <groupId>org.apache.dubbo</groupId>
  <artifactId>dubbo-spring-boot-starter</artifactId>
</dependency>

<!-- dubbo-registry-nacos -->
<dependency>
  <groupId>com.alibaba.nacos</groupId>
  <artifactId>nacos-client</artifactId>
</dependency>

<!-- duubo -->
<dependency>
  <groupId>org.apache.dubbo</groupId>
  <artifactId>dubbo</artifactId>
  <exclusions>
    <exclusion>
      <groupId>com.alibaba.fastjson2</groupId>
      <artifactId>fastjson2</artifactId>
    </exclusion>
  </exclusions>
</dependency>

3、dependencyManagement 新增

这里之所以多了个 snakeyaml是因为 redis 及其 nacos 里面引用的版本是 1.33，这个版本是有漏洞的，会提示 Provides transitive vulnerable dependency maven:org.yaml:snakeyaml:1.33

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-dependencies</artifactId>
      <version>${spring-cloud.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-dependencies</artifactId>
      <version>${spring-boot.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
    <dependency>
      <groupId>com.alibaba.cloud</groupId>
      <artifactId>spring-cloud-alibaba-dependencies</artifactId>
      <version>${spring-cloud-alibaba.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
    <dependency>
      <groupId>org.apache.dubbo</groupId>
      <artifactId>dubbo-bom</artifactId>
      <version>${dubbo.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
    <dependency>
      <groupId>org.yaml</groupId>
      <artifactId>snakeyaml</artifactId>
      <version>2.0</version>
    </dependency>
  </dependencies>
</dependencyManagement>

5、nacos 上 redis 和 undertow 配置变更

旧的 redis 和 undertow 配置

spring:
  redis:
    # Redis 数据库索引（默认0）
    database: 0
    # Redis 服务器地址
    host: localhost
    # Redis 服务器连接端口
    port: 6379
    # Redis 服务器连接密码
    password: ****

新的 redis 和 undertow 配置

server:
  undertow:
    threads:
      # 设置 undertow IO 线程数（一般是 CPU 个数）
      io: 4
      # IO 线程数 * 8
      worker: 32
    # 设置 undertow 每块 buffer 的空间大小
    buffer-size: 1024
    # 设置 undertow 是否分配的直接内存( NIO 直接分配的堆外内存)
    direct-buffers: true
spring:
  data:
    redis:
      # Redis 数据库索引（默认0）
      database: 0
      # Redis 服务器地址
      host: localhost
      # Redis 服务器连接端口
      port: 6379
      # Redis 服务器连接密码
      password: *****

6、nacos 上 dubbo 配置变化

dubbo 不需要在显示的配置订阅哪些服务了
如果不用 qos 不用的话，enable 设置为 false。
如果使用 qos 同一台多个服务需要配置端口
use-as-config-center、use-as-metadata-center 不生成配置文件

dubbo:
  application:
    metadata-type: local
    qos-enable: false
  scan:
    base-packages: com.**
  registry:
    address: nacos://localhost:8848
    use-as-config-center: false
    use-as-metadata-center: false
  protocol:
    name: dubbo
    port: -1
  consumer:
    timeout: 30000
    retries: 1
    check: false

7、启动类需要加上 @EnableDubbo
