ps:idea打开之后，发现test类报错：Cannot resolve symbol 'SpringJUnit4ClassRunner'，注解全部爆红.

**test类部分截图**：

import com.fasterxml.jackson.databind.ObjectMapper;
    import org.junit.Before;
    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.MediaType;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    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.result.MockMvcResultMatchers;
    import org.springframework.test.web.servlet.setup.MockMvcBuilders;
    import org.springframework.web.context.WebApplicationContext;
    import tk.mybatis.springboot.BussnessApplication;
    
    import java.util.List;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    //@SpringApplicationConfiguration(classes = BussnessApplication.class)
    //@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
    @SpringBootTest(classes = BussnessApplication.class,webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
    
    //@WebAppConfiguration
    public class test{
    	@Autowired
    	private UserMapper userMapper;
    	@Autowired
        private WebApplicationContext context;

解决方法：

去掉<scope>test</scope>.
