Java 在spring引导中动态加载测试属性文件和服务属性文件

为spring引导服务类编写junit。我的问题是，在junit期间，我有两个属性文件（一个用于应用程序，另一个用于测试），我想加载测试属性文件，在应用程序期间，我想加载应用程序属性文件。但它总是加载我的应用程序服务属性文件

Service.java

Test-service.properties

我需要在junit期间加载test-service.properties文件，并且需要在应用程序运行期间加载service.properties文件

Use the PropertySourcesPlaceholderConfigurer in order to mention the property for service and override with test configuration when you run the test through Junit

Something like this

    `
import org.apache.commons.lang3.ArrayUtils;
import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import java.io.IOException;

@Configuration
public class PropertyTestConfiguration {
    @Bean
    public PropertyPlaceholderConfigurer propertyPlaceholderConfigurer() throws IOException {
        final PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        ppc.setLocations(ArrayUtils.addAll(
                        new PathMatchingResourcePatternResolver().getResources("classpath*:application.properties"),
                        new PathMatchingResourcePatternResolver().getResources("classpath*:test.properties")
                )
        );
        return ppc;
    }

}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class PropertyTests {
    @Value("${elastic.index}")
    String index;
    @Configuration
    @Import({PropertyTestConfiguration.class})
    static class ContextConfiguration {
    }
}

`

您的测试属性文件应该位于测试文件夹中（参考资料中）

如果以application.properties（application-{profile}.properties）命名的属性文件和用于测试application-test.properties的属性文件，spring引导加载属性层次结构将是：booting application.properties，然后加载application-test.properties文件，spring从应用程序测试属性中重写应用程序属性中的值。 （）

如果您想告诉spring它应该在哪里搜索用于测试的属性文件，您可以使用以下内容：

@TestPropertySource({"classpath:/application.properties",classpath:/application-test.properties"})
@ActiveProfiles(profiles = "test")

但在应用程序服务类中，我们提到了propertysource和@value for private变量。我是否需要在服务类中添加一些东西，比如在服务中删除propertysource注释class@karthick如果我的回答对你有帮助，请随意投票）
