找不到 SpringJUnit4ClassRunner 类

Question

我正在尝试使用 SpringJUnit4ClassRunner 创建一个单元测试，但是每次我执行测试时，它都说它无法使用 mvn install 找到 SpringJUnit4ClassRunner。

\src\test\java\com\jr\freedom\util\JsonParserUtilTest.java:11: cannot find symbol
[ERROR] symbol: class SpringJUnit4ClassRunner
[ERROR] -> [Help 1]

这是我的代码

@RunWith(SpringJUnit4ClassRunner.class)
public class JsonParserUtilTest {

    private String jsonUser = "{ \"username\":\"jono111\",\"emailAddress\":\"jon@google.com\", \"password\":\"12345678\",\"firstName\":\"jono\", \"surname\":\"richy\", \"country\":\"united kingdom\",\"bio\":\"Bio stuff goes here about the user. where he comes from etc etc. all is well. lets go go go\" }";

    @Test
    public void testToJsonObject() {

        User user = new User();
        user.setBio("bio mate");
        user.setCountry("uk");
        user.setEmailAddress("jonney@hello.com");
        user.setFirstName("jono");
        user.setPassword("passwordfdsadsa");
        user.setUsername("crazy8");
        JSONObject jsonUser =  JsonPojo.toJsonObject(user);
        assertNotNull(jsonUser);
        assertNotNull(jsonUser.keys());
        System.out.println(jsonUser);

    }

    @Test
    public void testToObject(){
        JSONObject jsonUser = JSONObject.fromObject(jsonUser);
    }

这是我的 POM 文件：

我正在使用 springSource 工具套件 IDE 来开发这个 spring mvc 应用程序，并且在 IDE 上它突出显示 SpringJUnit4ClassRunner 作为一个错误，说它无法解决，尽管我在我的 pom 文件中包含了所有必要的依赖项。

谢谢

Answer 1

我下载了您的代码并使其在本地运行，只要我包含相关的导入语句：

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.junit.runner.RunWith;
import org.junit.Test;
...

也许您在某处缺少导入。

Answer 2

仅供参考，将此添加到您的 pom.xml 中

 <dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-test</artifactId>
  <scope>test</scope>
</dependency>

Answer 3

我修复了这个

• 删除我的本地 maven repo (~/.m2/repository) 和
• 在 Eclipse 中强制进行新构建（Project->Clean...）

Answer 4

如果您使用的是 linux，请打开终端并执行以下命令。 不要忘记在“用户名”所在的地方添加用户

cd /home/you-user/.m2/repository/
sudo rm -r junit

Answer 5

我不得不将 spring-test jar 放在 Java Build Path 的“顶部”

Answer 6

转到 pom.xml 并确保您的文件包含此依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.1.7.RELEASE</version>
</dependency>

还要确保在此依赖项中没有“范围”节点：

<scope>test</scope>

Answer 7

也许你丢了包裹

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-test</artifactId>
  <version>5.1.7.RELEASE</version>
</dependency>
