#### **Nacos依赖** ####

<dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>

application.properties

spring.application.name=service-user
    spring.cloud.nacos.discovery.server-addr=xxxxxx:8848

#### Sentinel依赖 ####

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

配置文件：

feign.sentinel.enabled=true
    spring.cloud.sentinel.transport.dashboard=localhost:8080

#### **Feign依赖** ####

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>

`ApiApplication.java`

加注解==@EnableFeignClients==

`UserClient.java`

加注解

@FeignClient(name = "service-user")

#### **负载均衡依赖** ####

<dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-loadbalancer</artifactId>
      </dependency>

#### **配置中心依赖** ####

<dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
    </dependency>
    
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bootstrap</artifactId>
    </dependency>

需要将**application.properties**修改为\*\*bootstrap.properties\*\*

如果需要通过nacos动态修改并获取配置中的参数，需要在controller层上面加上\*\*@RefreshScope\*\*注解

#### **网关依赖** ####

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>

`application.properties`

spring.cloud.gateway.discovery.locator.enabled=true

#### 关于SpringCloud的依赖版本 ####

导入以上的依赖之后

<dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${
        spring-cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>${
        spring-cloud-alibaba-version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
      </dependencyManagement>

注：spring-boot的版本应该改为2.6.3

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.6.3</version>
            <relativePath/> 
      </parent>

结合以上的信息pom中的依赖为：

// 版本信息
        <properties>
            <java.version>11</java.version>
            <spring-cloud.version>2021.0.1</spring-cloud.version>
            <spring-cloud-alibaba-version>2021.0.1.0</spring-cloud-alibaba-version>
        </properties>
        
        <dependencies>
        // 网关依赖
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-gateway</artifactId>
            </dependency>
        // 负载均衡依赖
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-loadbalancer</artifactId>
            </dependency>
        // nacos依赖
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            </dependency>
        // bootstrap配置文件依赖
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-bootstrap</artifactId>
            </dependency>
        // openfeign依赖
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-openfeign</artifactId>
            </dependency>
        // 配置中心依赖  
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            </dependency>
        </dependencies>
        
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>${
        spring-cloud.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <dependency>
                    <groupId>com.alibaba.cloud</groupId>
                    <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                    <version>${
        spring-cloud-alibaba-version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>

注：这里面的注释导入pom中需要给注上，不然会报错，然后如果刷新之后显示报红没有引用，直接关闭idea,然后重启就可以了。
