    导入依赖，因为测试mybatis的相关配置是否成功，所以要导入两个测试相关的依赖，spring-test ，前端页面没用jsp了，用的是freemarker模板语言，所以要导依赖,

     注意当你要使用mybatis-plus的时候，低版本（2.3.6；1.3.2）的mybatis的两个依赖会冲突

    改成（3.5.7和2.0.3）

    测试：

    • @RunWith注解的作用

      @RunWith就是一个运行器

      @RunWith(JUnit4.class)就是指用JUnit4来运行

      @RunWith(SpringJUnit4ClassRunner.class),让测试运行于Spring测试环境

      @RunWith(Suite.class)的话就是一套测试集合，
       

      1. package com.pro.service;
      2.  
      3. import junit.framework.TestCase;
      4. import org.junit.Test;
      5. import org.junit.runner.RunWith;
      6. import org.springframework.beans.factory.annotation.Autowired;
      7. import org.springframework.test.context.ContextConfiguration;
      8. import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
      9.  
      10. //测试的注解RunWith
      11. @RunWith(SpringJUnit4ClassRunner.class)
      12. @ContextConfiguration(locations = {"classpath:applicationContext.xml"})
      13. public class TestServiceTest extends TestCase {
      14.  
      15.     //因为我们是测试springMvc，所以需要通过注入的方式，故不能直接使用Junit来测试，
      16.     @Autowired
      17.     private TestService testService;
      18.  
      19.     @Test
      20.     public void save(){
      21.         com.pro.domain.Test t = new com.pro.domain.Test();
      22.         t.setContent("测试xxxxx");
      23.         testService.save(t);
      24.     }
      25. }
