java.lang.IllegalStateException: 找不到@SpringBootConfiguration，需要使用@ContextConfiguration 或@SpringBootTest(classes=...)

Question

嘿，在创建测试用例时，我已经开始使用 spring boot 测试框架学习 spring-boot junit 测试，我面临以下问题。

如何解决这个问题。

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test
    at org.springframework.util.Assert.state(Assert.java:70)
    at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.getOrFindConfigurationClasses(SpringBootTestContextBootstrapper.java:202)

    at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildDefaultMergedContextConfiguration(AbstractTestContextBootstrapper.java:323)

这是我的 RentalCarSystemApplicationTests.java

package com.test.project.rentalcarsystem;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RentalCarSystemApplicationTests {

       @Test
       public void contextLoads()
       {

       }
}

这是我的 TestWebApp.java

package com.test.project.rentalcarsystem;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.springframework.web.context.WebApplicationContext;
import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

public class TestWebApp extends RentalCarSystemApplicationTests {
    @Autowired
    private WebApplicationContext webApplicationContext;

    private MockMvc mockMvc;

@Before
public void setup() {
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test
public void testEmployee() throws Exception {
    mockMvc.perform(get("/car")).andExpect(status().isOk())
            .andExpect(content().contentType("application/json;charset=UTF-8"))
            .andExpect(jsonPath("$.setMilleage").value("24")).andExpect(jsonPath("$.setModelname").value("BMW"))
            .andExpect(jsonPath("$.setSeating_capacity").value("5")).andExpect(jsonPath("$.setType").value("SUV"))
            .andExpect(jsonPath("$.setCost").value("3000")).andExpect(jsonPath("$.setEmail").value("demo@gmail.com"))
            .andExpect(jsonPath("$.setNumber").value("9845658789")).andExpect(jsonPath("$.setPincode").value(560036));

}
}

Answer 1

从错误日志中它提示使用classes 属性为@SpringBootTest 所以

将@SpringBootTest 更改为@SpringBootTest(classes = Application.class)

给出类的完全分类名称，如下所示。

@SpringBootTest(classes=com.package.path.class)
