当前测试显示返回的两个对象相同,但是断言失败。有什么可以比较的吗?

 @Test
    public void test_search() throws Exception {
        TestObject testObject= createTestObject();

        ModelAndView expectedReturn = new ModelAndView("example/test", "testForm", testObject);
        expectedReturn.addObject("testForm", testObject);



        ModelAndView actualReturn = testController.search(testObject);

        assertEquals("Model and View objects do not match", expectedReturn, actualReturn);
    }

我建议您编写一个真正的Spring MVC测试。

例如就像我用弹簧靴做的一样

@AutoConfigureMockMvc
@SpringBootTest(classes = {YourSpringBootApplication.class})
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
@RunWith(SpringRunner.class)
public class RestControllerTest  {

       @Autowired
       private MockMvc mvc;

       @org.junit.Test
       public void test_search() throws Exception {
           TestObject testObject= createTestObject();

           mvc.perform(MockMvcRequestBuilders
            .get("/yourRestEndpointUri"))
            .andExpect(model().size(1))
            .andExpect(model().attribute("testObject", testObject))
            .andExpect(status().isOk());

       }

}

重要的是使用org.springframework.test.web.servlet.result.ModelResultMatchers.model()方法检查模型属性(在示例中为静态导入)
