在我的申请中

`CategoryDao` is a `interface`, `Category` is a model `class` 

我的代码是

CategoryTestCase.java

package com.binod.onlineshopping.category.test;
import com.binod.onlineshopping.category.dao.CategoryDao;
import com.binod.onlineshopping.category.model.Category;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import static org.testng.AssertJUnit.assertEquals;

/**
 * Created by binod on 7/13/17.
 */
public class CategoryTestCase {

    private static AnnotationConfigApplicationContext context;
    private static CategoryDao categoryDao;
    private Category category;

    @BeforeClass
    public static void init() {

        context = new AnnotationConfigApplicationContext();
        context.refresh();
        categoryDao = (CategoryDao) context.getBean("categoryDao");
    }

    @Test
    public void addCategory(){
        category=new Category();
        category.setCname("Television");
        category.setCdescription("TV is the product");
        category.setImageUrl("c_Tv.png");
     assertEquals("sucessfully inserted..",true,categoryDao.addCategory(category)); …

我看到很多教程,有些人使用maven dependency这样的方式

 <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>

有些人用maven dependency这样的方式

 <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.3.RELEASE</version>
    </dependency>

maven <version>${spring.version}</version>和<version>4.3.3.RELEASE</version>maven 之间的主要区别是什么？
