SpringBoot单元测试@ConfigurationProperties?

Question

从yml配置文件中读取数据。
不想使用@SpringBootTest这么重的测试方式，还有没有其他代价比较小的方式，完成单测。

Answer 1

已找到解决方案。

@ExtendWith(SpringExtension.class)
@EnableConfigurationProperties(CourseConfig.class)
@PropertySource(value = "classpath:application.yml", factory = YamlPropertySourceFactory.class)
class CourseConfigTest { }

这种即可，不过默认PropertySource只能解析properties这种配置文件。

import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.core.env.PropertiesPropertySource;
import org.springframework.core.env.PropertySource;
import org.springframework.core.io.support.EncodedResource;
import org.springframework.core.io.support.PropertySourceFactory;

import java.io.IOException;
import java.util.Properties;

public class YamlPropertySourceFactory implements PropertySourceFactory {

    @Override
    public PropertySource<?> createPropertySource(String name, EncodedResource encodedResource) throws IOException {
        YamlPropertiesFactoryBean factory = new YamlPropertiesFactoryBean();
        factory.setResources(encodedResource.getResource());

        Properties properties = factory.getObject();

        return new PropertiesPropertySource(encodedResource.getResource().getFilename(), properties);
    }
}
