搭建互联网架构学习--005--框架初步拆分ssm单一框架
经过前边的准备步骤，服务器基本搭建完毕，接下来就开始一步步搭建框架了。
拆分单一结构：拆分的目的是为下一步引入dubbo做准备的。
把下边这个单一maven框架进行拆分
这个就是一个简单的maven项目，对应的表是：我们的表建在192.168.75.3上的mysql的enterprise表
拆分成如下的几个工程，其实很多公司都是这么做的，我们以前的项目也是这样的，我们一般把common、pojo、Dao、service、controller、web（或者把controller和web放在一块），其中parent是个pom工程，定义jar包版本等；facade是接口，service是接口实现，这俩是jar包工程，web-service是controller是个war包工程。
（对于他这个命名，很费解）
为了保持和课程的一致性，把到此步骤每个工程的代码贴出来吧：
一：xxxx-parent 父工程
pom工程，就是一pom.xml

二：xxxx-facade 接口层
实体类 Enterprise.java：
package com.xxxx.mybatis.domain;
import java.io.Serializable;
public class Enterprise implements Serializable{
/**
*

private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private String address;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name == null ? null : name.trim();
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address == null ? null : address.trim();
}
}
Mapper:
package com.xxxx.mybatis.IDao;

Service:

public interface IEnterpriseService {
public Enterprise getEnterpriseById(int enterpriseId);
}
pom:
