Java MockMVC不是自动连接的，它是空的

我在测试类中注入MockMvc时遇到了一个问题。我尝试了一些选择，但没有一个有效

1选项：与此处基本相同，手动创建MockMvc

2选项：

    package com.application.controller;
    
    import org.junit.jupiter.api.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    import org.springframework.test.web.servlet.MockMvc;
    
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class DishControllerTest {

    @Autowired
    public MockMvc mockMvc;


    @Test
    void getDishes() throws Exception {
        this.mockMvc.perform(
                get("/"))
                .andDo(print())
                .andExpect(status().isOk());
    }

还尝试了使用@WebMvcTest注释而不是@AutoConfigureMockMvc的第二个选项

MockMVC始终为空。 堆栈跟踪：
