在AWS Lambda中运行时，Spring Boot应用程序会引发MultipartException

我刚刚尝试使用以下文章在AWS Lambda上运行Spring Boot应用程序：https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot

基本请求运行正常，但是发送文件似乎会引起问题。在本地运行应用程序可以正常运行：

@RestController
@EnableWebMvc
public class PingController {
    @RequestMapping(path = "/ping", method = RequestMethod.GET)
    public Map<String, String> ping() {
        Map<String, String> pong = new HashMap<>();
        pong.put("pong", "Hello, World!");
        return pong;
    }

    @RequestMapping(path = "/ping", method = RequestMethod.POST)
    public Map<String, Long> ping(@RequestParam("file") MultipartFile file) {
        Map<String, Long> pong = new HashMap<>();
        pong.put("filesize", file.getSize());
        return pong;
    }
}

/ ping上的GET按预期返回有效消息：

{
    "pong": "Hello, World!"
}

将POST发送到包含图像的/ ping会导致以下异常：

{
    "timestamp": 1540237302941,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "org.springframework.web.multipart.MultipartException",
    "message": "Could not parse multipart servlet request; nested exception is java.lang.IllegalArgumentException: File path not allowed: /image.jpeg",
    "path": "/ping"
}

在application.properties文件中添加以下行无济于事：

spring.http.multipart.location=/tmp/

指定资源是否存在甚至都没有关系。到/ ping2的POST（不存在）会导致相同的异常。

CloudWatch的Stacktrace：

之前有人遇到过错误吗？我还需要配置其他内容吗？

答案 0 :(得分：1)

这是Amazon库中的错误，已于几天前修复。 here提供了更多信息。只需确保使用1.2版或更高版本即可：

<dependency>
    <groupId>com.amazonaws.serverless</groupId>
    <artifactId>aws-serverless-java-container-spring</artifactId>
    <version>1.2</version>
</dependency>
