4-3 买家类目-service

DAO:ProductCategory。Service可以简化一些，叫CategoryService。

package com.imooc.sell.service;

import com.imooc.sell.dataobject.ProductCategory;

import java.util.List;

/**

 *  类目

 *  Created by zhongzh

 *  2018-05-26 23:53

 */

public interface CategoryService {

   ProductCategory findOne(Integer categoryId);//管理后台使用

   List<ProductCategory> findAll();//管理后台用的

   List<ProductCategory>  findByCategoryTypeInTest(List<Integer> categoryTypeList);

   //新增和更新都是save方法

    ProductCategory save(ProductCategory productCategory);

}

package com.imooc.sell.service.impl;

import com.imooc.sell.dataobject.ProductCategory;

import com.imooc.sell.repository.ProductCategoryRepository;

import com.imooc.sell.service.CategoryService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import java.util.List;

/**

 *  Created by zhongzh

 *  2018-05-27 0:02

 */

@Service //Service端要加一个注解

public class CategoryServiceImpl implements CategoryService {

    @Autowired

    private ProductCategoryRepository repository;//引入DAO

    @Override

    public ProductCategory findOne(Integer categoryId) {

        return repository.getOne(categoryId);

    }

    @Override

    public List<ProductCategory> findAll() {

        return repository.findAll();

    }

    @Override

    public List<ProductCategory> findByCategoryTypeInTest(List<Integer> categoryTypeList) {

        return repository.findByCategoryTypeIn(categoryTypeList);

    }

    @Override

    public ProductCategory save(ProductCategory productCategory) {

        return repository.save(productCategory);

    }

}

com.imooc.sell.service.impl.CategoryServiceImpl的四个方法都给它测试一下

测试类

package com.imooc.sell.service.impl;

import org.junit.Test;

import static org.junit.Assert.*;

public class CategoryServiceImplTest {

    @Test

    public void findOne() {

    }

    @Test

    public void findAll() {

    }

    @Test

    public void findByCategoryTypeInTest() {

    }

    @Test

    public void save() {

    }

}

增加注解

package com.imooc.sell.service.impl;

import com.imooc.sell.dataobject.ProductCategory;

import org.junit.Assert;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.*;

@RunWith(SpringRunner.class)

@SpringBootTest

public class CategoryServiceImplTest {

    @Autowired

    private CategoryServiceImpl categoryService;

    @Test

    public void findOne() {

        ProductCategory productCategory = categoryService.findOne(1);

        Assert.assertEquals(new Integer(1),productCategory.getCategoryId());

    }

    @Test

    public void findAll() {

    }

    @Test

    public void findByCategoryTypeInTest() {

    }

    @Test

    public void save() {

    }

}

com.imooc.sell.dataobject.ProductCategory要增加一个getCategoryId()方法才行

package com.imooc.sell.dataobject;

//import javax.persistence.Table;

import lombok.Data;

import lombok.Getter;

import lombok.Setter;

import lombok.ToString;

import org.hibernate.annotations.DynamicUpdate;

import org.hibernate.annotations.Proxy;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import java.util.Date;

/**

 * 类目

 * Created by zhongzh

 * 2018-05-20 9:31

 * s_product_category

 */

//@Table(name = "s_product_category")

@Entity//把数据库映射成对象

@Proxy(lazy = false)

@DynamicUpdate //

@Data//@Data包含生成getter、setter和toString()方法

//@Getter//如果只是需要Getter那就引入Getter

//@Setter//如果只是需要Setter那就引入Setter

//@ToString//如果只是需要ToString那就引入ToString

public class ProductCategory{

     /** 类目id. */

     @Id//Id是主键,自增类型的。

     //@GeneratedValue//相当于调用了native策略

     //@GeneratedValue(strategy = GenerationType.AUTO)

     @GeneratedValue(strategy = GenerationType.IDENTITY)

     private Integer categoryId;//字段名的命名方式也是一样的，把下划线改成为空。

     /** 类目名字. */

     private String categoryName;

     /** 类目编号. */

     private Integer categoryType;

     /** 创建时间. */

     private Date createTime;

     /** 修改时间. */

     private Date updateTime;

    //不要忘了Getter和Setter方法

    /*

    public Integer getCategoryId() {

        return categoryId;

    }

    public void setCategoryId(Integer categoryId) {

        this.categoryId = categoryId;

    }

    public String getCategoryName() {

        return categoryName;

    }

    public void setCategoryName(String categoryName) {

        this.categoryName = categoryName;

    }

    public Integer getCategoryType() {

        return categoryType;

    }

    public void setCategoryType(Integer categoryType) {

        this.categoryType = categoryType;

    }

    public Date getCreateTime() {

        return createTime;

    }

    public void setCreateTime(Date createTime) {

        this.createTime = createTime;

    }

    public Date getUpdateTime() {

        return updateTime;

    }

    public void setUpdateTime(Date updateTime) {

        this.updateTime = updateTime;

    }

    @Override

    public String toString() {

        return "ProductCategory{" +

                "categoryId=" + categoryId +

                ", categoryName='" + categoryName + '\'' +

                ", categoryType=" + categoryType +

                '}';

    }

    */

    public ProductCategory(String categoryName, Integer categoryType) {

        this.categoryName = categoryName;

        this.categoryType = categoryType;

    }

    public ProductCategory() {

        super();

    }

    public Integer getCategoryId() {

        return categoryId;

    }

}

package com.imooc.sell.service.impl;

import com.imooc.sell.dataobject.ProductCategory;

import org.junit.Assert;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import java.util.Arrays;

import java.util.List;

import static org.junit.Assert.*;

@RunWith(SpringRunner.class)

@SpringBootTest

public class CategoryServiceImplTest {

    @Autowired

    private CategoryServiceImpl categoryService;

    @Test

    public void findOne() {

        ProductCategory productCategory = categoryService.findOne(10);

        Assert.assertEquals(new Integer(1),productCategory.getCategoryId());

    }

    @Test

    public void findAll() {

        List<ProductCategory> productCategoryList = categoryService.findAll();

        Assert.assertNotEquals(0,((List) productCategoryList).size());//如果集合的总数不等于null，如果productCategoryList的size不等于0，至少是有内容的。

    }

    @Test

    public void findByCategoryTypeInTest() {

        List<ProductCategory> productCategoryList = categoryService.findByCategoryTypeInTest(Arrays.asList(1,2,4));

        Assert.assertNotEquals(0,productCategoryList.size());

    }

    @Test

    public void save() {

        ProductCategory productCategory = new ProductCategory("男生专享",10);

        ProductCategory result = categoryService.save(productCategory);

        Assert.assertNotNull(result);

    }

}

因为类目并没有给买家端提供专门的接口，所以类目相关Controller层不用再写了。而是商品，下一节开发商品相关的功能。
