Spring Boot 加载应用上下文失败

Question

有一个 springboot 应用程序，它使用 file-inbound-adapter 从源目录读取文件。为其编写 junit 测试用例。 Junit 测试用例在我的本地 Eclipse 中成功执行。但是从部署在另一台机器上的竹子/詹金斯运行它时遇到问题。

在执行 spring boot junit 测试用例时无法加载应用程序上下文。 'filesInChannel.adapter.source' 原因：java.lang.IllegalArgumentException：源目录 [/filepath] 不存在。

这是什么原因造成的。对此有何建议/建议？是因为竹子部署机器的一些权限问题吗？

已经为测试用例编写了单独的配置。但不确定为什么它指向原始 xml 以在执行测试用例时加载应用程序上下文。

错误：

   java.lang.IllegalStateException: Failed to load ApplicationContext
    Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'filesInChannel.adapter': Cannot resolve reference to bean 'filesInChannel.adapter.source' while setting bean property 'source'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'filesInChannel.adapter.source': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Source directory [/filepath] does not exist.

    Caused by: java.lang.IllegalArgumentException: Source directory [/filepath] does not exist.

file-process.xml 源代码：

<file:inbound-channel-adapter id="filesInChannel"
        directory="/filepath/" auto-startup="false" scanner="recursiveScanner" auto-create-directory="true">
                <integration:poller id="poller" max-messages-per-poll="${max.messages.per.poll}" fixed-rate="${message.read.frequency}" task-executor="pollingExecutor">
            <integration:transactional transaction-manager="transactionManager" />
        </integration:poller>       
    </file:inbound-channel-adapter>

测试用例：

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = TestConfig.class)
public class FileApplicationTests {

    @Test
    public void contextLoads() {
    }

}

测试配置：

@Configuration
@ImportResource({ "classpath:test-file-process.xml" })
public class TestConfig {

}

test-file-process.xml源码：

<file:inbound-channel-adapter id="filesInChannel"
        directory="file:${java.io.tmpdir}/filepath/" auto-startup="false" scanner="recursiveScanner" auto-create-directory="true">
                <integration:poller id="poller" max-messages-per-poll="${max.messages.per.poll}" fixed-rate="${message.read.frequency}" task-executor="pollingExecutor">
            <integration:transactional transaction-manager="transactionManager" />
        </integration:poller>
    </file:inbound-channel-adapter>

Answer 1

我认为<file:inbound-channel-adapter> 的问题实际上创建了几个bean，其中一个是FileReadingMessageSource，条件如下：

Assert.isTrue(this.directory.exists(),
            "Source directory [" + this.directory + "] does not exist.");

就在其afterPropertiesSet() 中，独立于auto-startup="false"。

恐怕这个 bean 并没有被覆盖，只是因为它的 id 是自动生成的。

这就是另一个配置没有帮助的原因。

我建议你看看 profiles 支持：https://docs.spring.io/spring/docs/current/spring-framework-reference/core.html#beans-definition-profiles

然后将 <file:inbound-channel-adapter> 包装成类似这样的东西：

<beans:beans profile="!test">
</beans:beans>
