业务开发
只需按以下五个步骤就能完成一个模块的基本功能开发，也可以使用铭飞提供的在线代码生成器功能快速生成以下业务代码。下面将通过扩展通用模型basic,快速开发一个博客模块,模块名定义为mblog。
博文的表结构：
CREATE TABLE `mblog_article` (
`article_basic_id` int NOT NULL COMMENT 'basic表主键',
`article_content` text NULL COMMENT '博文内容',
PRIMARY KEY (`article_basic_id`) ,
CONSTRAINT `fk_article_basic_id` FOREIGN KEY (`article_basic_id`) REFERENCES `basic` (`BASIC_ID`) ON DELETE CASCADE ON UPDATE NO ACTION
)
COMMENT = '博文表，通过扩展basic实现';
第一步：实体
package net.mingsoft.mblog.entity;
import com.mingsoft.basic.entity.BasicEntity;
import java.util.Date;
import org.springframework.data.elasticsearch.annotations.Document;
/**
* 博客文章实体
* @author 铭飞团队
* @version
* 版本号：100<br/>
* 创建日期：2015-6-20 16:05:42<br/>
* 历史修订：<br/>
*/
@Document(indexName = "blogarticle")
public class ArticleEntity extends BasicEntity {
private static final long serialVersionUID = 1500537942802L;
/**
* 博客文章自增长ID
*/
private Integer articleBasicId;
/**
* 文章内容
*/
private String articleContent;
public ArticleEntity(){}
public ArticleEntity(Integer articleBasicId) {
this.articleBasicId = articleBasicId;
}
public ArticleEntity(String articleContent) {
this.articleContent = articleContent;
}
/**
* 设置博客文章自增长ID
*/
public void setArticleBasicId(Integer articleBasicId) {
this.articleBasicId = articleBasicId;
}
/**
* 获取博客文章自增长ID
*/
public Integer getArticleBasicId() {
return this.articleBasicId;
}
/**
* 设置文章内容
*/
public void setArticleContent(String articleContent) {
this.articleContent = articleContent;
}
/**
* 获取文章内容
*/
public String getArticleContent() {
return this.articleContent;
}
}
第二步：持久化
IArticleDao.java
package net.mingsoft.mblog.dao;
import com.mingsoft.base.dao.IBaseDao;
import com.mingsoft.util.*;
import java.util.*;
import org.springframework.stereotype.Component;
import net.mingsoft.mblog.entity.ArticleEntity;
/**

* @version
* 版本号：100<br/>
* 创建日期：2016-6-20 16:05:42<br/>
* 历史修订：<br/>
*/
@Component("blogArticleDao")
public interface IArticleDao extends IBaseDao {
}
IArticleDao.xml

底层代码重写
主要分视图代码重写、Java业务代码重写
视图代码重写只需要在当前开发项目中创建与底层视图文件路径、文件名一致的文件即可，例如：重写登录界面，只需要在当前项目创建/WEB-INF/manager/login.ftl文件，当项目发布的时候当前的login.ftl会覆盖底层提供的login.ftl；
后台业务代码的重写不像视图那样简单，需要在当前项目创建对应的类，如果类名出现相同，必须使用Spring注解定义bean名称，例如：@Controller("xxxx") @Service("xxxxxx")
