SpringCloud整合Dubbo3開發示例代碼

Spring Cloud和Dubbo是兩個在微服務架構中常用的技術。Spring Cloud提供了構建分佈式系統的各種工具，而Dubbo是一個高性能、輕量級的Java RPC框架。將它們結合起來可以創建一個強大的微服務架構。

以下是一個簡單的示例，展示如何使用Spring Cloud和Dubbo 3進行整合開發。

1.項目結構

lua
/demo-project  
    /provider  
        pom.xml  
        ProviderApplication.java  
        ProviderController.java  
        ProviderService.java  
    /consumer  
        pom.xml  
        ConsumerApplication.java  
        ConsumerController.java  
        ConsumerService.java  
    /common  
        pom.xml (包含provider和consumer的依賴)

2.provider

pom.xml:

xml
<dependencies>  
    <dependency>  
        <groupId>org.springframework.boot</groupId>  
        <artifactId>spring-boot-starter-web</artifactId>  
    </dependency>  
    <dependency>  
        <groupId>com.alibaba.dubbo</groupId>  
        <artifactId>dubbo</artifactId>  
        <version>3.0.0</version>  
    </dependency>  
</dependencies>

ProviderApplication.java:

java
import org.springframework.boot.SpringApplication;  
import org.springframework.boot.autoconfigure.SpringBootApplication;  
import org.springframework.context.annotation.Bean;  
import org.springframework.web.bind.annotation.RestController;  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.PathVariable;  
import org.springframework.web.bind.annotation.PostMapping;  
import org.springframework.web.bind.annotation.RequestBody;  
import org.springframework.web.bind.annotation.RequestParam;  
import org.springframework.web.bind.annotation.ResponseBody;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.*;  
import javax.servlet.*;  
import javax.servlet.*;  
import javax.servlet.*;  
import javax.servlet.*;
