Answer 1

在您的问题中，mockMvc对象未初始化。在字段顶部添加@mock注释。

@Mock
MockMvc mockMvc;

通过添加，

@Before
public void setUp() throws Exception {
    MockitoAnnotations.initMocks(this);
    this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
}

之后，如果您在运行测试方法之前检查所有对象是否存在，将会非常好，方法是添加

@Test
public void testMock() {
    assertNotNull(mockMvc);
}
