SpringBootTest注释无法解析为类型

Question

我的SpringBootTest注释无法解析为类型。这里有同样的问题，但似乎添加了依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>2.0.5.RELEASE</version>
    <scope>test</scope>
</dependency>

无法做到这一点。整个问题是我想使用@ContextConfiguration但它已被弃用，建议的做法是使用@SpringBootTest（classes = MyMainClass.class）

Answer 1

如果您使用父启动器，则不需要在测试依赖项中定义版本，这在加载时可能会发生冲突。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.5.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

所以完整的pom会是这样的..

<?xml version="1.0" encoding="UTF-8"?>
  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion>

    <groupId>com.kj</groupId>
    <artifactId>demo-multi-schema</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>demo</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>

    </properties>

Answer 2

尝试使用依赖项2.0.3。我现在正在使用这个版本。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>2.0.3.RELEASE</version>
    <!--<scope>test</scope>-->
</dependency>

Answer 3

我会尝试在Spring Test类中使用@RunWith注释和@Test，我有一个例子：

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 YourClassAppTest {

    @Test
    public void contextLoads() {
    }

}

希望它能解决问题
