java.lang.IllegalStateException：找不到@SpringBootConfiguration，您需要在测试中使用@ContextConfiguration

Question

我们应该在src下单独创建test文件夹还是test文件夹？

我的测试班位置是：server/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

我正在为类ManualTriggerController编写Junit，它的路径是:server/src/main/java/com/cellpointmobile/mconsole/controller/ManualTriggerController.java

我的主类，即 Application.java 位于以下位置： server/src/main/java/com/cellpointmobile/mconsole/app/Application.java

你能告诉我我做错了什么吗？

Answer 1

正如你所说， 我的测试班地点是：server/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

应该是， server/src/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

还要确保您的测试类ManualTriggerControllerTest 已使用@SpringBootTest 进行注释，或者您也可以使用@ContextConfiguration 但@SpringBootTest 更简单，因为您无需担心其他任何事情，因为它负责上下文加载、配置让您的测试运行。

您的ManualTriggerControllerTest 应如下所示，

@RunWith(SpringRunner.class)
@SpringBootTest
public class ManualTriggerControllerTest{
/* your code */
}

我希望这会有所帮助！

按照已经使用的包，测试运行成功。

在 src/main/java 里面

package com.an.csv.mvc;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController("/myclass")
public class TestControllerEx {

 @GetMapping
  public ResponseEntity control(){
    return new ResponseEntity("success",HttpStatus.OK);
  }
}

Spring Boot 主类：

package com.an.csv;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class})
public class CSVBatchApplication {

  public static void main(String[] args) {
    SpringApplication.run(CSVBatchApplication.class, args);
  }
}

在src/test/java下

import org.junit.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 com.an.csv.CSVBatchApplication;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = CSVBatchApplication.class)
@AutoConfigureMockMvc
public class ControllerIntegrationTest {

  @Autowired private MockMvc mockMvc;

  @Test
  public void testController() throws Exception {
    mockMvc
        .perform(get("/myclass"))
        .andExpect(status().isOk());
  }
}
