【Java Web】【7】SSM spring+struts+mybatis整合（四）SSM中action，dao，service，serviceimpl

1.    POJO，也就是bean或者model，你们怎么称乎都可以

package com.shdl.hterp.beans;
import org.apache.ibatis.type.Alias;
import com.shdl.hterp.common.Page;
@Alias("companyBean")
public class CompanyBean extends Page {
	private String companyid;	// 主键ID
	private String companyname;	// 公司名称
	private String companycode;	// 纳税人识别号
	private String companyaddress;	// 企业经营地址
	private String companyaccount;	// 开户行以及账号
	private String companytel;	// 联系电话
	private String companyremark;	// 备注
	private String companytype;	// 公司类型
	private String companyorderno;	// 排序字段
	private String deletetime; // 删除时间 
	public String getCompanyid() {
		return companyid;
	}
	public void setCompanyid(String companyid) {
		this.companyid = companyid;
	}
	public String getCompanyname() {
		return companyname;
	}
	public void setCompanyname(String companyname) {
		this.companyname = companyname;
	}
	public String getCompanycode() {
		return companycode;
	}
	public void setCompanycode(String companycode) {
		this.companycode = companycode;
	}
	public String getCompanyaddress() {
		return companyaddress;
	}
	public void setCompanyaddress(String companyaddress) {
		this.companyaddress = companyaddress;
	}
	public String getCompanyaccount() {
		return companyaccount;
	}
	public void setCompanyaccount(String companyaccount) {
		this.companyaccount = companyaccount;
	}
	public String getCompanytel() {
		return companytel;
	}
	public void setCompanytel(String companytel) {
		this.companytel = companytel;
	}
	public String getCompanyremark() {
		return companyremark;
	}
	public void setCompanyremark(String companyremark) {
		this.companyremark = companyremark;
	}
	public String getCompanytype() {
		return companytype;
	}
	public void setCompanytype(String companytype) {
		this.companytype = companytype;
	}
	public String getCompanyorderno() {
		return companyorderno;
	}
	public void setCompanyorderno(String companyorderno) {
		this.companyorderno = companyorderno;
	}
	public String getDeletetime() {
		return deletetime;
	}
	public void setDeletetime(String deletetime) {
		this.deletetime = deletetime;
	}
}

2.    action

package com.shdl.hterp.business.company;

import java.io.File;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import com.shdl.hterp.beans.CarBean;

}

PS：查询数据库的时候：companyService.getXXXXX，中的get方法与mybatis-company.xml的标签id都要一一对应

3.    Service

package com.shdl.hterp.business.company;

import java.util.List;

import com.shdl.hterp.beans.CompanyBean;
import com.shdl.hterp.business.base.BaseService;

/**
 * 【车辆基本信息维护】业务接口
 * @author CodeMaker
 * @createTime 2017-6-22 15:18:31
 */
public interface CompanyService extends BaseService<CompanyBean> {
	
	/**
	 * 查询查询项目公司
	 * @return
	 * @throws Exception
	 */
	public List<CompanyBean> getProduct() throws Exception;
	
}

4.    ServiceImpl

package com.shdl.hterp.business.company;


import java.util.List;

import com.shdl.hterp.beans.CompanyBean;
import com.shdl.hterp.business.base.BaseDao;
import com.shdl.hterp.business.base.BaseServiceImpl;

/**
 * 【车辆基本信息维护】业务实现类
 * @author CodeMaker
 * @createTime 2017-6-22 15:18:31
 */
public class CompanyServiceImpl extends BaseServiceImpl<CompanyBean> implements CompanyService{
	// 属性定义
	private CompanyDao companyDao;

	public CompanyDao getCompanyDao() {
		return companyDao;
	}

	public void setCompanyDao(CompanyDao companyDao) {
		this.companyDao = companyDao;
	}

	@Override
	public BaseDao<CompanyBean> getBaseDao() {
		return companyDao;
	}
	
	@Override
	public List<CompanyBean> getProduct() throws Exception {
		return companyDao.getProduct();
	}
	
}

5.    Dao

package com.shdl.hterp.business.company;


import java.util.List;

import com.shdl.hterp.beans.CompanyBean;
import com.shdl.hterp.business.base.BaseDao;


public interface CompanyDao extends BaseDao<CompanyBean>{
	
	/**
	 * 查询项目公司
	 * @return
	 * @throws Exception
	 */
	public List<CompanyBean> getProduct() throws Exception;
	
	
	
}

PS：所有的action，dao，service，serviceImpl都是继承自公共Base方法，其实也不用写公共方法，直接写也可以，后续项目多的话，就不用一个一个写，继承也可以
