在前面的章节中,我们着手介绍了dubbo的相关知识,在这个基础之上,我们可以考虑将dubbo服务应用于我们的分布式系统了,从今天开始,我们会详细介绍如何将dubbo和spring集成并应用于我们的分布式系统。

 

1. 创建ant-bookmark-facade项目(dubbo服务接口),其中pom.xml文件定义如下:

<?xml version="1.0"?>
<project
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.sml.sz</groupId>
<artifactId>ant-project</artifactId>
<version>1.0.0</version>
</parent>
<artifactId>ant-member-facade</artifactId>
<packaging>jar</packaging>
<name>ant-member-facade</name>
<url>http://maven.apache.org</url>
<description>ant的收藏模块Dubbo服务接口包,提供相关的Dubbo服务入口</description>
 
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<!-- ant framework begin -->
<!--  系统核心框架包 -->
<dependency>
<groupId>com.sml.sz</groupId>
<artifactId>ant-framework</artifactId>
</dependency>
<!-- ant framework end -->
</dependencies>
</project>
<?xml version="1.0"?>
<project
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.sml.sz</groupId>
<artifactId>ant-project</artifactId>
<version>1.0.0</version>
</parent>
<artifactId>ant-member-facade</artifactId>
<packaging>jar</packaging>
<name>ant-member-facade</name>
<url>http://maven.apache.org</url>
<description>ant的会员模块Dubbo服务接口包,提供相关的Dubbo服务入口</description>
 
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<!-- ant framework begin -->
<!--  系统核心框架包 -->
<dependency>
<groupId>com.sml.sz</groupId>
<artifactId>ant-framework</artifactId>
</dependency>
<!-- ant framework end -->
</dependencies>
</project>

2. 定义实体entity,因为接口中的对象要使用

package com.sml.sz.bookmark.entity;

import org.hibernate.validator.constraints.Length;

import com.sml.sz.common.persistence.DataEntity;

/**
 * 我的收藏链接管理Entity
 * 
 * @author ant
 * @version 2016-01-30
 */
public class Bookmark extends DataEntity<Bookmark> {

	private static final long serialVersionUID = 1L;
	private String tagId;
	private BookmarkTag bookmarkTag; // 业务主表ID 父类
	private String bookmarkname; // 名称
	private String bookmarkurl; // 名称

	public Bookmark() {
		super();
	}

	public Bookmark(String id) {
		super(id);
	}

	public Bookmark(BookmarkTag bookmarkTag) {
		this.tagId = bookmarkTag.getId();
		this.bookmarkTag = bookmarkTag;
	}

	@Length(min = 1, max = 64, message = "业务主表ID长度必须介于 1 和 64 之间")
	public String getTagId() {
		return tagId;
	}

	public void setTagId(String tagId) {
		this.tagId = tagId;
	}

	@Length(min = 1, max = 100, message = "名称长度必须介于 1 和 100 之间")
	public String getBookmarkname() {
		return bookmarkname;
	}

	public void setBookmarkname(String bookmarkname) {
		this.bookmarkname = bookmarkname;
	}

	@Length(min = 1, max = 100, message = "名称长度必须介于 1 和 100 之间")
	public String getBookmarkurl() {
		return bookmarkurl;
	}

	public void setBookmarkurl(String bookmarkurl) {
		this.bookmarkurl = bookmarkurl;
	}

	public BookmarkTag getBookmarkTag() {
		return bookmarkTag;
	}

	public void setBookmarkTag(BookmarkTag bookmarkTag) {
		this.bookmarkTag = bookmarkTag;
	}

}
package com.sml.sz.bookmark.entity;

import java.util.List;

import org.hibernate.validator.constraints.Length;

import com.google.common.collect.Lists;
import com.sml.sz.common.persistence.DataEntity;

/**
 * 我的收藏链接管理Entity
 * @author ant
 * @version 2016-01-30
 */
public class BookmarkTag extends DataEntity<BookmarkTag> {
	
	private static final long serialVersionUID = 1L;
	private String bookmarktagname;		// 标签名称
	private List<Bookmark> bookmarkList = Lists.newArrayList();		// 子表列表
	
	public BookmarkTag() {
		super();
	}

	public BookmarkTag(String id){
		super(id);
	}

	@Length(min=1, max=64, message="标签名称长度必须介于 1 和 64 之间")
	public String getBookmarktagname() {
		return bookmarktagname;
	}

	public void setBookmarktagname(String bookmarktagname) {
		this.bookmarktagname = bookmarktagname;
	}
	
	public List<Bookmark> getBookmarkList() {
		return bookmarkList;
	}

	public void setBookmarkList(List<Bookmark> bookmarkList) {
		this.bookmarkList = bookmarkList;
	}
}

  

3. 定义接口类,此类会在dubbo生产者和dubbo消费者之间被引用

package com.sml.sz.bookmark.service;

import java.util.List;

import com.sml.sz.bookmark.entity.BookmarkTag;
import com.sml.sz.common.persistence.Page;

/**
 * 我的收藏链接管理Service
 * 
 * @author ant
 * @version 2016-01-30
 */
public interface BookmarkTagFacade {
	public BookmarkTag get(String id);

	public List<BookmarkTag> findList(BookmarkTag bookmarkTag);

	public Page<BookmarkTag> findPage(Page<BookmarkTag> page, BookmarkTag bookmarkTag);

	public void save(BookmarkTag bookmarkTag);

	public void delete(BookmarkTag bookmarkTag);
}
