java - 获取NoSuchMethodError : org. hamcrest.core.StringContains.containsStringIgnoringCase

标签 java maven pom.xml junit5 hamcrest

我在 JUnit 5 集成测试中遇到问题，即我的项目无法识别 Hamcrest 2.1 版本中的 containsStringIgnoringCase 方法。

集成测试:

  @Test
  void nutritionixSearchInstantTest() throws Exception {

    ResultActions resultActions =
        mockMvc
            .perform(
                MockMvcRequestBuilders.get("/nutritionix/productDetails?query=grilled")
                    .contentType(MediaType.APPLICATION_JSON))
            .andDo(print())
            .andExpect(MockMvcResultMatchers.status().isOk())
            .andExpect(MockMvcResultMatchers.jsonPath("$", hasSize(40)))
            .andExpect(
                MockMvcResultMatchers.jsonPath(
                    "$[*].food_name", Every.everyItem(containsStringIgnoringCase("grilled"))))
            .andExpect(MockMvcResultMatchers.jsonPath("$[0].food_name", containsString("grilled")));
  }

行:

.andExpect(MockMvcResultMatchers.jsonPath("$[*].food_name", Every.everyItem(containsStringIgnoringCase("grilled"))))

产生错误:

我试图从打包中排除 JUnit 和 Hamcrest 依赖

spring-boot-starter-test

并添加我自己的 Hamcrest 版本，但 java 编译器在正确识别此方法时仍然存在问题。

此外，我在 IntelliJ 中尝试了每种可能的静态导入，例如:

import static org.hamcrest.Matchers.containsStringIgnoringCase;
import static org.hamcrest.CoreMatchers.containsStringIgnoringCase;
import static org.hamcrest.core.StringContains.containsStringIgnoringCase;

并且只有第一个 IntelliJ 才能识别“这种方法，没有红色下划线，但尽管如此，我无法以积极的结果进行测试。

测试类中的完整导入列表如下:

import static org.hamcrest.CoreMatchers.containsString;
import static org.hamcrest.Matchers.containsStringIgnoringCase;
import static org.hamcrest.Matchers.hasSize;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import org.hamcrest.core.Every;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
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.http.MediaType;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

Hamcrest tutorial

考虑到上面的教程，我试图在我的 pom 中组合依赖项的顺序，但这并没有带来理想的效果。

非常感谢您对我还能做什么的建议。

最佳答案

我找到了解决方案:

在命令行中输入命令后:

mvn 依赖项:tree -Dscope=test

我意识到 hamcrest-core 包和旧版本 1.3 有问题。 

[INFO] +- org.hamcrest:hamcrest-library:jar:2.1:test
[INFO] |  \- org.hamcrest:hamcrest-core:jar:1.3:test

下面的依赖解决了一个问题。

<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest-core</artifactId>
    <version>2.1</version>
    <scope>test</scope>
</dependency>
