一、引入jar包

  hamcrest-all-1.3.jar
  junit-4.11.jar
  spring-test-4.1.6.RELEASE.jar

二、测试代码

package com.dcits.cms.test;

import com.alibaba.fastjson.JSONObject;
import com.dcits.base.model.ResultObject;
import com.dcits.cms.model.ExchangeEarnings;
import com.dcits.cms.service.ExchangeEarningsNewService;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultHandlers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import java.util.HashMap;
import java.util.Map;
