GitHub Actions中TestContainers集成测试加载ApplicationContext失败，本地正常

在GitHub Actions流水线运行测试时，出现IllegalState Failed to load ApplicationContext错误，但本地IntelliJ使用Maven执行测试完全正常，仅流水线中两个Repository测试类报错。

CI流水线配置

排查原因与解决办法

核心原因分析

ClassroomRepositoryTest缺少数据源配置：该测试类仅禁用了默认测试数据库，但未通过@DynamicPropertySource注入TestContainers的MySQL连接信息，导致Spring无法找到有效数据源，加载ApplicationContext失败。本地环境可能存在隐式配置，流水线环境无此条件。
GitHub Actions Runner资源限制：Runner的CPU/内存有限，MySQL容器启动或初始化超时，导致无法建立连接。
Maven Surefire插件兼容性：当前使用的3.1.2版本可能与TestContainers、JUnit5存在兼容性问题。

解决步骤

给ClassroomRepositoryTest补充数据源配置
添加和UserRepositoryTest一致的@DynamicPropertySource方法，注入容器连接属性：

@DynamicPropertySource
static void dynamicProperties(DynamicPropertyRegistry registry) {
    registry.add("spring.datasource.url", mySQLContainer::getJdbcUrl);
    registry.add("spring.datasource.username", mySQLContainer::getUsername);
    registry.add("spring.datasource.password", mySQLContainer::getPassword);
}

确保容器完全初始化
添加@BeforeAll方法，等待MySQL容器启动并可用：

@BeforeAll
static void setupContainer() {
    mySQLContainer.start();
    // 验证数据库连接
    try (Connection conn = DriverManager.getConnection(
            mySQLContainer.getJdbcUrl(),
            mySQLContainer.getUsername(),
            mySQLContainer.getPassword()
    )) {
        // 连接成功则继续
    } catch (SQLException e) {
        throw new RuntimeException("测试容器连接失败", e);
    }
}

升级Maven Surefire插件
在pom.xml中更新插件版本至最新稳定版（如3.2.5）：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.2.5</version>
        </plugin>
    </plugins>
</build>

增强流水线Docker环境
在CI配置中显式初始化Docker服务，确保容器运行环境正常：
```
- name: Setup Docker
  uses: docker/setup-buildx-action@v3
```
获取详细错误日志
修改测试步骤，添加-e参数输出完整堆栈，定位具体错误：
```
- name: Unit tests
  run: mvn -B test -e --file pom.xml
```
