spring boot 集成dubbo的示例演示
本demo使用spring boot 2.4.1版本集成 dubbo 2.7.15
1.创建maven项目及其子模块
父工程pom.xml
<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"> <modelVersion>4.0.0</modelVersion> <groupId>com.lee.demo.dubbo.demo</groupId> <artifactId>coupon-platform-normal-springboot</artifactId> <version>1.0-SNAPSHOT</version> <packaging>pom</packaging> <modules> <module>coupon-service-api</module> <module>coupon-service-provider</module> <module>user-service-api</module> <module>user-service-provider</module> <module>coupon-portal</module> </modules> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <spring-boot.version>2.4.1</spring-boot.version> <dubbo.version>2.7.15</dubbo.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>${spring-boot.version}</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>com.lee.demo.dubbo.demo.userapi</groupId> <artifactId>user-service-api</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>com.lee.demo.dubbo.demo.couponapi</groupId> <artifactId>coupon-service-api</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-dependencies-zookeeper</artifactId> <version>2.7.15</version> <type>pom</type> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-bom</artifactId> <version>${dubbo.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> </project>
2.其中coupon-service-api为接口
3.coupon-service-provider为接口实现类,注意,其启动类需要添加注解@EnableDubbo
pom.xml
<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.lee.demo.dubbo.demo</groupId> <artifactId>coupon-platform-normal-springboot</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>com.lee.demo.dubbo.demo.couponprovider</groupId> <artifactId>coupon-service-provider</artifactId> <name>coupon-service-provider</name> <description>coupon-service-provider</description> <properties> <java.version>1.8</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-dependencies-zookeeper</artifactId> <type>pom</type> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>com.lee.demo.dubbo.demo.couponapi</groupId> <artifactId>coupon-service-api</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.3.7.RELEASE</version> <configuration> <mainClass>com.lee.demo.dubbo.demo.CouponServiceProviderApplication</mainClass> </configuration> <executions> <execution> <id>repackage</id> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
配置文件
实现类添加注解@DubboService
4.coupon-portal为web访问层,配置如下
pom.xml
<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.lee.demo.dubbo.demo</groupId> <artifactId>coupon-platform-normal-springboot</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>com.lee.demo.dubbo.demo.portal</groupId> <artifactId>coupon-portal</artifactId> <name>coupon-portal</name> <description>coupon-portal</description> <properties> <java.version>1.8</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.lee.demo.dubbo.demo.userapi</groupId> <artifactId>user-service-api</artifactId> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-dependencies-zookeeper</artifactId> <type>pom</type> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.3.7.RELEASE</version> <configuration> <mainClass>com.lee.demo.dubbo.demo.CouponPortalApplication</mainClass> </configuration> <executions> <execution> <id>repackage</id> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
启动类
controller访问层,属性注入时,如果为RPC调用,则需要添加注解@DubboReference
5.依次启动接口提供者(springboot项目)
coupon-service-provider、user-service-provider以及web层coupon-portal
6.前端访问:127.0.0.1:8080/coupon
至此完成了springboot 2.4.1集成 dubbo 2.7.15
