(十六) 构建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:

<span style=”font-size: 16px;”><?xml version=”1.0″?>
<project
xsi:schemaLocation=”http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/m…d”
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&lt;/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/m…d”
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&lt;/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></span>

  1. 定义实体entity,因为接口中的对象要使用

<span style=”font-size: 16px;”>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;
}

}</span>
<span style=”font-size: 16px;”>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;
}

}</span>

  1. 定义接口类,此类会在dubbo生产者和dubbo消费者之间被引用

<span style=”font-size: 16px;”>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);

}</span>
