Spring Cloud Alibaba环境搭建

在搭建Spring Cloud Alibaba环境时，需要引入一些依赖。其中，需要导入以下依赖：

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<dependency>
    <groupId>com.jd</groupId>
    <artifactId>springcloudalibaba-common-service</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>

在代码中，可以创建一个`OrderNacosApplication`类来启动应用，并在该类中添加`@LoadBalanced`注解来启用默认的负载均衡器Ribbon。代码如下：

package com.pushihao;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
public class OrderNacosApplication {
    public static void main(String\[\] args) {
        SpringApplication.run(OrderNacosApplication.class, args);
    }

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) {
        return restTemplateBuilder.build();
    }
}

此外，还可以创建一个`OrderApplication`类来启动应用，并在该类中添加`@Bean`注解来创建`RestTemplate`实例。代码如下：

package com.pushihao;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
public class OrderApplication {
    public static void main(String\[\] args) {
        SpringApplication.run(OrderApplication.class, args);
    }

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        return builder.build();
    }
}

以上是搭建Spring Cloud Alibaba环境的一些基本配置和依赖引入。
