最近,时光有点荒废。书也没怎么读,博客也不更新。反省一分钟…
前几天写 工具 的时候,需要调用一个dubbo服务,但之前是配置的简单的 Java 项目,所以这边简单记载一下这个过程。
- 首先新建一个Java的 maven 项目,以下是pom文件,dubbo要基于Spring搞事的。
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.xxxx</groupId> <artifactId>dubbo-test-check</artifactId> <version>1.0-SNAPSHOT</version> <properties> <org.springframework.version>3.2.14.RELEASE</org.springframework.version> </properties> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>cn.xxxx.test.DubboTest</mainClass> </manifest> </archive> <classesDirectory> </classesDirectory> </configuration> </plugin> <plugin> <artifactId>maven-assembly-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> <configuration> <descriptorRefs> <!-- 将依赖一起打包到 JAR --> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive> <manifest> <mainClass>cn.xxxx.test.DubboTest</mainClass> </manifest> </archive> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.5</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.7</version> </dependency> <dependency> <groupId>dom4j</groupId> <artifactId>dom4j</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.4.10</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.5</version> </dependency> <dependency> <groupId>com.101tec</groupId> <artifactId>zkclient</artifactId> <version>0.4</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.2.14.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework.version}</version> </dependency> </dependencies> </project>
- Dubbo配置相关,
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <dubbo:application name="webank_check" /> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry address="zookeeper://192.168.0.1:2181?backup=192.168.0.2:2181,192.168.0.3:2181"/> <dubbo:reference id="xxxxxApi" interface="com.xxxx.webank_api.xxxxxApi" version="1.0.0" check="false" timeout="10000" group="product"/> <bean id="weBankTicket" class="cn.xxxx.test.WeBankTicket"> <property name="xxxxx" ref="xxxxxApi"/> </bean> </beans>
- 主要的DubboTest类
public class DubboTest { public static void main(String[] args) { try { DubboTest dubboTest = new DubboTest(); ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml"); WeBankTicket weBankTicket = (WeBankTicket) ac.getBean("weBankTicket"); String ticket = weBankTicket.getTicket(APP_ID); ... ... } catch (Exception e) { e.printStackTrace(); } } }
- 操作类
public class WeBankTicket { xxxxxApi xxxxx; public void setxxxxx(xxxxxApi xxxxx) { this.xxxxx = xxxxx; } public xxxxxApi getxxxxx() { return xxxxx; } public String getTicket(String appId) { WeBankWeChatTicketReq weBankWeChatTicketReq = new WeBankWeChatTicketReq(); weBankWeChatTicketReq.setAppId(appId); if (null == weBankWeChatTicket) { System.out.println("======================"); } WeBankWeChatTicketResp weBankWeChatTicketResp = xxxxx.getSignTicket(weBankWeChatTicketReq); return xxxxx.getSignTicket(); } }
因为是一个消费服务,主要是从zookeeper中拿到接口调用就行。没开始注解,所以bean配置麻烦了点。算是一个小工具吧。如果有本地小工具调用生产dubbo的时候,可以这么做。
