使用MockMvc测试 Controller

使用MockMvc可以做到controller层的测试。如果直接得到controller，然后调用指定的方法是不会通过拦截器等外层组件的，使用mockMvc可以。

package com.lomi.mockMvc;

import cn.hutool.json.JSONUtil;
import com.lomi.controller.TestController;
import com.lomi.entity.Goods;
import com.lomi.service.GoodsService;

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.http.HttpHeaders;
import org.springframework.http.MediaType;

import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
