基于springboot集成dubbo

使用quickstart方式构建springboot项目,创建一个dubbo服务提供者，消费者，以及api模块：


父pom：

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.lchtest.springboot.dubbo</groupId>
	<artifactId>springboot-dubbo-example</artifactId>
	<packaging>pom</packaging>
	<version>1.0-SNAPSHOT</version>

	<properties>
		<java.version>1.8</java.version>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<spring-boot.version>2.3.7.RELEASE</spring-boot.version>
		<wicket.version>1.3.2</wicket.version>
		<jetty.version>6.1.4</jetty.version>
	</properties>
	<modules>
		<module>springboot-dubbo-sample-api</module>
		<module>springboot-dubbo-sample-provider</module>
		<module>spring-boot-dubbo-sample-consumer</module>
	</modules>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
			<version>${spring-boot.version}</version>
		</dependency>

		<!-- springboot继承dubbo,只需要dubbo-spring-boot-starter和nacos-client  -->
		<dependency>
			<groupId>org.apache.dubbo</groupId>
			<!-- 第三方的包，不是spirng的包有前缀，spirng的包是以spring开头  -->
			<artifactId>dubbo-spring-boot-starter</artifactId>
			<version>2.7.7</version>
		</dependency>

		<dependency>
			<groupId>com.alibaba.nacos</groupId>
			<artifactId>nacos-client</artifactId>
			<version>1.2.1</version>
		</dependency>
	</dependencies>
</project>

API模块：

provider模块 添加

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>com.lchtest.springboot.dubbo</groupId>
        <artifactId>springboot-dubbo-example</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.lchtest.springboot.dubbo</groupId>
    <artifactId>springboot-dubbo-sample-provider</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-dubbo-sample-provider</name>
    <description>Demo project for Spring Boot</description>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>com.lchtest.springboot.dubbo</groupId>
            <artifactId>springboot-dubbo-sample-api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>

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

实现API模块的接口，使用@DubboService注解发布服务

配置文件如下：

# 应用名称
spring.application.name=springboot-dubbo-sample-provider
dubbo.protocol.name=dubbo
dubbo.scan.base-packages=com.lchtest.springboot.dubbo.springbootdubbosampleprovider.service
# -1 让系统生成端口号
dubbo.protocol.port=-1
# 注册中心地址，跟springcloud集成dubbo不同，这里是用dubbo的注册中心配置项
dubbo.registry.address=nacos://192.168.61.1:8848

服务消费者consumer模块，添加dubbo-spring-boot-starter， nacos-client，spring-boot-starter-web 的依赖，

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <groupId>com.lchtest.springboot.dubbo</groupId>
        <artifactId>springboot-dubbo-example</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.lchtest.springboot.dubbo</groupId>
    <artifactId>spring-boot-dubbo-sample-consumer</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>spring-boot-dubbo-sample-consumer</name>
    <dependencies>
        <dependency>
            <groupId>com.lchtest.springboot.dubbo</groupId>
            <artifactId>springboot-dubbo-sample-api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

        <!-- springboot集成dubbo,只需要dubbo-spring-boot-starter和nacos-client  -->
        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <!-- 第三方的包，不是spirng的包有前缀，spring的包是以spring开头  -->
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.7.7</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba.nacos</groupId>
            <artifactId>nacos-client</artifactId>
            <version>1.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
</project>

并调用provider模块发布的服务：

配置文件：

# 应用名称
spring.application.name=spring-boot-dubbo-sample-consumer
server.port=8888
# 注册中心地址，跟springcloud集成dubbo不同，这里是用dubbo的注册中心配置项
dubbo.registry.address=nacos://192.168.61.1:8848

然后启动nacos注册中心，provider模块和consumer模块，调用接口：
