我正在APIGetway顶部部署的Spring引导应用程序作为Lambda-获取错误
Class not found: com.myapp.app.LambdaHandler: java.lang.ClassNotFoundException
java.lang.ClassNotFoundException: com.myapp.app.LambdaHandler. Current classpath: file:/var/task/
当创建Jar文件时，我看到有3个文件夹-BOOT-INF、META-INF、org.
我的包在BOOT_INF中->类->com.>myapp->应用程序->LambdaHandler
使用-serverless.yml进行部署
从命令提示符CLI进行部署-无服务器部署
StreamLambdaHandler.java
public class StreamLambdaHandler implements RequestStreamHandler {
private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
try {
handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
} catch (Exception e) {
// if we fail here. We re-throw the exception to force another cold start
e.printStackTrace();
throw new RuntimeException("Could not initialize Spring Boot Application", e);
}
}
@Override
public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
throws IOException {
handler.proxyStream(inputStream, outputStream, context);
}
}
Application.java
@SpringBootApplication
@Configuration
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {
/**
* Create required HandlerMapping, to avoid several default HandlerMapping instances being created
*/
@Bean
public HandlerMapping handlerMapping() {
return new RequestMappingHandlerMapping();
}
/**
* Create required HandlerAdapter, to avoid several default HandlerAdapter instances being created
*/
@Bean
public HandlerAdapter handlerAdapter() {
return new RequestMappingHandlerAdapter();
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
我的控制器-
@RestController
@EnableWebMvc
@Profile("lambda")
@RequestMapping("/app/v2")
public class ClientInformation {
@Value("${clientDetails.userName}")
private String userName;
@Value("${clientDetails.userId}")
private int userId;
@Value("${clientDetails.userAddress}")
private String userAddress;
@GetMapping("/")
public Map<String, Object> getDetails() {
Map<String, Object> rtn = new HashMap<>();
rtn.put("message", "App is working fine !!!");
return rtn;
}
@GetMapping("/information")
public Map<String, Object> getInformation() {
Map<String, Object> rtn = new HashMap<>();
rtn.put("name", userName);
rtn.put("id", userId);
return rtn;
}
@GetMapping("/ping")
public Map<String, Object> getD() {
Map<String, Object> rtn = new HashMap<>();
rtn.put("name", "Ping is happening !!!");
rtn.put("status", "200");
return rtn;
}
}
无服务器.yml-
service: myapplication-api
provider:
name: aws
runtime: java11
memorySize: 512
timeout: 15
profile: default
stage: production
package:
artifact: target/myapp-api-0.0.1-SNAPSHOT-exec.jar

pom.xml
我能知道我做错了什么吗-

</project>您需要配置serverless.yml以指定StreamLambdaHandler的完整包作为handler属性。
例如，如果类在com.myapp包中。您需要指定com.myapp.StreamLambdaHandler
您当前正在指定com.myapp.app.LambdaHandler，而这是一个不存在的类。
在Springboot中，我们有所有的@Controller、@Service、annotation。因此，Lamba不够聪明，无法理解这一点。除非我们做一些破解。但这对于亚马逊网络服务来说是不可取的。我们能做什么-
我们可以使用Spring cloud函数。这是链接-
