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> 
  
  
 <dependency> 
 <groupId>com.sml.sz</groupId> 
 <artifactId>ant-framework</artifactId> 
 </dependency> 
  
 </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> 
  
  
 <dependency> 
 <groupId>com.sml.sz</groupId> 
 <artifactId>ant-framework</artifactId> 
 </dependency> 
  
 </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); 
 }

架构代码如下:
