用maven工程搭建SSM项目模板-阿里云开发者社区

1 创建maven工程

不带骨架的java工程

2.创建子模块

itcast-ssm-web

itcast-ssm-domain

itcast-ssm-service

itcast-ssm-dao

itcast-ssm-utils

其中创建itcast-ssm-web时注意我们选择一个web工程

3.在父工程下的pom.xml添加依赖

            </plugins>
        </pluginManagement>
    </build>
</project>

4.在itcast-ssm-web下的main目录下面创建java和resources两个包，在resourcesl里面编写整合ssm配置文件

5.配置文件整合applicationContext.xml，spring-mvc.xml，web.xml

配置文件里面的内容就在这个图中applicationcontext.xml是spring的配置文件

spring整合mybatis就是用spring来控制SqlSessionFactory的管理

6.编写domain,dao,service,和controller里面的代码，例如查询所有

domain中的product类

package com.domain;
import com.utils.DateUtils;
import org.springframework.format.annotation.DateTimeFormat;
import java.util.Date;
/**
 * 产品信息
 */
public class Product {
    private String id; // 主键
    private String productNum; // 编号 唯一
    private String productName; // 名称
    private String cityName; // 出发城市
    @DateTimeFormat(pattern="yyyy-MM-dd HH:mm")
    private Date departureTime; // 出发时间
//    这个是为了格式化数据 方便展示
    private String departureTimeStr;
    private double productPrice; // 产品价格
    private String productDesc; // 产品描述
    private Integer productStatus; // 状态 0 关闭 1 开启
//    这个也是为了格式化数据，方便展示
    private String productStatusStr;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getProductNum() {
        return productNum;
    }
    public void setProductNum(String productNum) {
        this.productNum = productNum;
    }
    public String getProductName() {
        return productName;
    }
    public void setProductName(String productName) {
        this.productName = productName;
    }
    public String getCityName() {
        return cityName;
    }
    public void setCityName(String cityName) {
        this.cityName = cityName;
    }
    public Date getDepartureTime() {
        return departureTime;
    }
    public void setDepartureTime(Date departureTime) {
        this.departureTime = departureTime;
    }
    public String getDepartureTimeStr() {
        if(departureTime!=null){
            departureTimeStr= DateUtils.date2String(departureTime,"yyyy-MM-dd HH:mm:ss");
        }
        return departureTimeStr;
    }
    public void setDepartureTimeStr(String departureTimeStr) {
        this.departureTimeStr = departureTimeStr;
    }
    public double getProductPrice() {
        return productPrice;
    }
    public void setProductPrice(double productPrice) {
        this.productPrice = productPrice;
    }
    public String getProductDesc() {
        return productDesc;
    }
    public void setProductDesc(String productDesc) {
        this.productDesc = productDesc;
    }
    public Integer getProductStatus() {
        return productStatus;
    }
    public void setProductStatus(Integer productStatus) {
        this.productStatus = productStatus;
    }
    public String getProductStatusStr() {
//        显示状态信息
        if (productStatus != null) {
            // 状态 0 关闭 1 开启
            if(productStatus==0)
                productStatusStr="关闭";
            if(productStatus==1)
                productStatusStr="开启";
        }
        return productStatusStr;
    }
    public void setProductStatusStr(String productStatusStr) {
        this.productStatusStr = productStatusStr;
    }
}

dao里面的

package com.dao;
import com.domain.Product;
import org.apache.ibatis.annotations.Select;
import java.util.List;
public interface IProductDao {
//    查询所有
    @Select("select * from product")
    List<Product> findAll() throws Exception;
    //    @Insert("insert into product(productNum,productName,cityName,departureTime,productPrice,productDesc,productStatus)
//    values(#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})")
//    void save(Product product);
}

service

package com.service;
import com.domain.Product;
import java.util.List;
public interface IProductService {
     public List<Product> findAll() throws Exception;
}
实现类
package com.service.impl;
import com.domain.Product;
import com.dao.IProductDao;
import com.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
//事务
@Transactional
public class ProductServiceImpl implements IProductService {
    //自动按照类型注入
    @Autowired
    private IProductDao productDao;
    public List<Product> findAll() throws Exception {
//        List<Product> list = productDao.findAll();
        return productDao.findAll();
    }
}

controller

package com.controller;
import com.domain.Product;
import com.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
//控制器
@Controller
@RequestMapping("/product")
public class ProductController {
//    引入serviced
    @Autowired
    private IProductService productService;
    //查询全部产品
    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception {
        //创建一个ModelAndView对象
        ModelAndView mv = new ModelAndView();
        List<Product> products = productService.findAll();
        mv.addObject("productList", products);
        mv.setViewName("product-list");
//        mv.setViewName("test");
        return mv;
    }
}
