构建springmvc+mybatis+dubbo分布式平台-dubbo服务接口定义

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);
}
