我写信给你，是因为我在Spring Boot中创建了一个带有相关测试的简单控制器类，但是当我开始测试时，出现了错误： “预期状态：<200>但原为：<404>”
如果您需要完整的堆栈跟踪，则为：

我的控制器类是：
package com.xantrix.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/api")
public class SalutiRestController
{
@GetMapping(value = "/test")
public String getGreetings()
{
return "Saluti, sono il tuo primo web services";
}
}
我使用JUnit4运行的测试是：
package com.xantrix.webapp;
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.jsonPath;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import com.xantrix.controller.SalutiRestController;
@RunWith(SpringRunner.class)
@WebMvcTest(SalutiRestController.class)
public class TestRestController
{
@Autowired
private MockMvc mvc;
@Test
public void testGreetingsController()
throws Exception
{
mvc.perform(get("/api/test")
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(jsonPath("$")
.value("Saluti, sono il tuo primo web services"))
.andDo(print());
}
}
