分佈式服務-DUBBOX(五):集成服務生產者

一、demo-base中pom.xml引入dubbo以及zookeeper相關

<!--dubbo-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.8.4</version>
    <exclusions>
        <exclusion>
            <artifactId>spring</artifactId>
            <groupId>org.springframework</groupId>
        </exclusion>
    </exclusions>
</dependency>

<!--zookeeper-->
<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.6</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.101tec/zkclient -->
<dependency>
    <groupId>com.101tec</groupId>
    <artifactId>zkclient</artifactId>
    <version>0.7</version>
</dependency>

 

二、建立module:demo-provider

1）工程結構以下

2）pom.xml

<?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">
    <parent>
        <artifactId>demo</artifactId>
        <groupId>com.company</groupId>
        <version>1.0.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo-provider</artifactId>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>com.company</groupId>
            <artifactId>demo-service</artifactId>
            <version>1.0.0</version>
        </dependency>

        <dependency>
            <groupId>com.company</groupId>
            <artifactId>demo-api</artifactId>
            <version>1.0.0</version>
        </dependency>
    </dependencies>

</project>

3）UserApiImpl.java

package com.company.provider.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.company.api.dto.UserDTO;
import com.company.api.iapi.UserApi;
import com.company.data.model.User;
import com.company.service.UserService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;

/**
 * Created by wsyi on 2016/11/29.
 */
@Service
public class UserApiImpl implements UserApi {
    private static final Logger LOGGER = LoggerFactory.getLogger(UserApiImpl.class);

    @Autowired
    private UserService userService;

    @Override
    public UserDTO qryById(Long id) {
        UserDTO userDTO = new UserDTO();
        User user = userService.qryUserById(id);
        BeanUtils.copyProperties(user,userDTO);
        return userDTO;
    }
}

注意：@Service爲com.alibaba.dubbo.config.annotation.Service，非Spring中註解Service。

4）spring-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        ">

        <!--掃描spring註解中bean對象-->
        <context:component-scan base-package="com.company"/>

        <!--spring最多加載一個context:property-placeholder-->
        <context:property-placeholder location="classpath*:jdbc.properties"/>

        <!--將其餘配置文件-->
        <import resource="classpath*:spring-mybatis.xml"/>

</beans>

5）spring-provider.xml:

<?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">

    <!--掃描dubbo註解類-->
    <dubbo:annotation package="com.company.provider.impl" />
</beans>

6）dubbo.properties

7）web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:META-INF/spring/spring-*.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

 

三、demo-provider運行

1）啓動zookeeper、dubbo-admin服務。

2）將demo-provider部署到tomcat上，啓動服務。

3）dubbo-admin服務
