这个问题很难解释,所以请看一下这个项目:https://github.com/darzz/boot_bug 这是最小化的设置,可以重现错误。
描述: 应用程序堆栈是Spring Boot with Spring Data和Spring Batch。 src / main / resources / queries 下有 testNamedQuery.hbm.xml 文件。
从 应用程序 类运行时,批处理作业成功完成,日志中没有例外。但是,当从 ApplicationNotWorking 类运行时,这是完全复制的,只是放入测试源根目录,批处理作业将失败:

所以看起来像,在运行测试时,* .hbm.xml文件未加载! 经过研究和调试,我想,我可能已经找到了原因 - 持久性单元根url被设置为测试目标/测试类,但映射文件在/ target / classes中。
可能的原因在我看来可能类似于此处所描述的http://blog.carbonfive.com/2007/05/17/using-classpath-vs-classpath-when-loading-spring-resources/
但是我不知道如何在Spring Boot中解决这个问题,而不是为了测试目的而创建persistence.xml配置。不想将* .hbm.xml文件从main / resources复制到test / resources。
有没有人有想法?

@Autowired
private ResourceLoader rl;
@Bean
public LocalSessionFactoryBean sessionFactory() throws IOException {
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setMappingLocations(loadResources());
return sessionFactoryBean;
}
public Resource[] loadResources() {
Resource[] resources = null;
try {
resources = ResourcePatternUtils.getResourcePatternResolver(rl)
.getResources("classpath:/hibernate/*.hbm.xml");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return resources;
}

如果我正确理解了这个问题,你想运行Spring Boot Test,它应该从类路径中获取* .hbm文件。
你在哪里保存* .hbm文件?
您必须确保所有* .hbm文件都保存在src / main / resources下。因此,当您运行测试类时,它将调用从src引用* .hbm文件的实际类/主/资源。
如果上述解决方案没有帮助,那么您需要共享项目文件结构。

I looked into the git project. It seems you need to change the ApplicationNotWorking.java since it is a test class hence should be something as below:
//src/test/java
package bug;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.stackoverflow.springboot.BatchProcessing;
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class )
public class ApplicationNotWorking {
//Inject required bean which you want to test.
@Autowired
private BatchProcessing bProcess;
//If above @Autowired BatchProcessing do not work then you can object
//directly to kick off the test. BatchProcessing bProcess = new
//BatchProcessing();
//This way you can test each method
@Test
public void testBatchProcessing(){
System.out.println("***BatchProcessing: " + bProcess.batchProcess());
}
}
