SSM框架的注解配置文件的优劣取舍

探索SSM理论的前提，应该是在对框架基础的运作方式有一定了解，以下是个人Android后台项目,用SSM框架快速搭建，以下是代码，主要 观察结构。

代码结构：

model实体类

Idao抽象接口

Iservice抽象接口

daomapping数据库具体操作的配置文件

service服务类

controller控制器类

Article.java

package com.linuxidc.model; import java.util.Date; public class Article { private Integer id; private String title; private String author; private Date date; private Integer zan; private Integer pinglun; private Integer fenxiang; private String tag1; private String tag2; private String content; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title == null ? null : title.trim(); } public String getAuthor() { return author; } public void setAuthor(String author) { this.author = author == null ? null : author.trim(); } public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } public Integer getZan() { return zan; } public void setZan(Integer zan) { this.zan = zan; } public Integer getPinglun() { return pinglun; } public void setPinglun(Integer pinglun) { this.pinglun = pinglun; } public Integer getFenxiang() { return fenxiang; } public void setFenxiang(Integer fenxiang) { this.fenxiang = fenxiang; } public String getTag1() { return tag1; } public void setTag1(String tag1) { this.tag1 = tag1 == null ? null : tag1.trim(); } public String getTag2() { return tag2; } public void setTag2(String tag2) { this.tag2 = tag2 == null ? null : tag2.trim(); } public String getContent() { return content; } public void setContent(String content) { this.content = content == null ? null : content.trim(); } }

ArticleMapper.java

package com.linuxidc.dao; import java.util.List; import com.linuxidc.model.Article; public interface ArticleMapper { int deleteByPrimaryKey(Integer id); int insert(Article record); int insertSelective(Article record); Article selectByPrimaryKey(Integer id); int updateByPrimaryKeySelective(Article record); int updateByPrimaryKeyWithBLOBs(Article record); int updateByPrimaryKey(Article record); List<Article> getAll(); List<Article> getTitleList(String tag); }
