一.项目结构

e2-parent：父工程，打包方式pom，管理jar包的版本号。

    |           项目中所有工程都应该继承父工程。

    |--e2-common：通用的工具类通用的pojo。打包方式jar

    |--e2-manager：服务层工程。聚合工程。Pom工程

        |--e2-manager-dao：打包方式jar

        |--e2-manager-pojo：打包方式jar

        |--e2-manager-interface：打包方式jar(服务层与表现层分离,需要通过interface沟通,所以单独打成jar以便依赖)

        |--e2-manager-service：打包方式：war(服务层与表现层分离,需要打成war)

    |--e2-manager-web：表现层工程。打包方式war

二.创建e2-parent父工程,打包方式pom，管理jar包的版本号

POM文件

					<path>/</path>
					<port>8080</port>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

五.创建e2-manager-pojo,Module工程,打包方式jar

POM文件

<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>
    <groupId>com.e2mall</groupId>
    <artifactId>e2-manager</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>e2-manager-pojo</artifactId>
</project>

六.创建e2-manager-dao,Module工程,打包方式jar

POM文件(依赖pojo以及mybatis相关jar)

<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">

	<dependencies>
		<!-- 依赖实体 -->
		<dependency>

			<artifactId>druid</artifactId>
		</dependency>
	</dependencies>

	<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
	<build>
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
		</resources>
	</build>
</project>

七.创建e2-manager-interface,Module工程,打包方式jar

POM文件(依赖实体jar)

<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">

			<version>0.0.1-SNAPSHOT</version>
		</dependency>
	</dependencies>
</project>

八.创建e2-manager-service,Module工程,打包方式war(服务层和表现层分离,需要提供war包聚合)

创建完项目会报错,没有web.xml文件,可以右键生成

POM文件(依赖interface层,依赖dao层,依赖dubbo资源调度和治理中心的管理工具)

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

九.创建e2-manager-web,继承e2-parent,表现层工程。打包方式war工程(表现层和服务层分离)

创建项目完会报错,没有web.xml文件,右键生成

POM文件(依赖接口工程,表现层与服务层沟通)

十.整合完毕,测试Dubbo表现层调用服务层代码

interface层

public interface IItemService {

    /**
     * 根据ID获取item
     * 
     * @param itemId
     * @return
     */
    TbItem findItemById(Long itemId);

}

service层

@Service
public class ItemServiceImpl implements IItemService {
    @Autowired
    private TbItemMapper itemMapper;

    @Override
    public TbItem findItemById(Long itemId) {
	return itemMapper.selectByPrimaryKey(itemId);
    }

}

web层

@Controller
public class ItemController {

    @Autowired
    private IItemService itemService;

    @RequestMapping(value = "/item/{itemId}")
    @ResponseBody
    public TbItem getItemById(@PathVariable Long itemId) {
	TbItem tbItem = itemService.findItemById(itemId);
	return tbItem;
    }
}

由于服务层与表现层分离成了两个war包,所以需要通过dubbo框架在服务层发布服务,表现层消费服务,

使用Zookeeper注册中心进行服务地址的注册和查找

Zookeeper的安装与自启动

①在服务层发布服务

引入dubbo约束

</beans>

十一.Dubbo监控中心部署

①将dubbo监控中心war包放在zookeeper所在服务器的tomcat

ps:注意dubbo-admin-2.5.4在jdk1.8版本访问会404

dubbo-admin-2.5.4(支持jdk1.8)

②这样可以直接进行注册中心监控(账号:root 密码:root)

③:如果dubbo-admin-2.5.4没有部署在zookeeper所在服务器,那就需要改配置文件指向zookeeper服务器

进入dubbo-admin-2.5.4/WEB-INF/dubbo.properties,修改为zookeeper注册中心服务器地址
