java - AWS lambda + spring boot = 不连接组件

Question

我正在尝试在我的 AWS lambda 应用程序中使用 spring-boot 来调用 SOAP Web 服务。但看起来它没有 Autowiring 我的 SOAP 组件。 这是我的代码:

@SpringBootApplication(scanBasePackages={"com.fenix"})
@EnableAutoConfiguration
@ComponentScan
public class Aplicacao extends SpringBootServletInitializer {

public static void main(String[] args) {
    SpringApplication.run(Aplicacao.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder springApplicationBuilder) {
    return springApplicationBuilder.sources(Aplicacao.class);
}
}

@Configuration
public class Beans {

@Bean
public Jaxb2Marshaller marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.tranzaxis.schemas", "org.radixware.schemas", "org.xmlsoap.schemas", "com.compassplus.schemas");
    return marshaller;
}

@Bean
public TranClient tranClient(Jaxb2Marshaller marshaller) {
    TranClient client = new TranClient();
    client.setDefaultUri("http://rhel72.tx:12301?wsdl");
    client.setMarshaller(marshaller);
    client.setUnmarshaller(marshaller);
    return client;
}

@Bean(name = "Tran")
public TranClient getTranClient() {
    return tranClient(marshaller());
}
}



public class PostMovimentacao extends Handler implements Service {

@Autowired
@Qualifier("Tran")
private TranClient tranClient;

@Inject
private PessoaCompassBO pessoaCompassBO;

private CompassConfig compassConfig;

private static final Logger LOGGER = Logger.getLogger(PostMovimentacao.class);

@Override
protected ResponseEntity execute(ApiRequest request, Context context) throws HttpException {
    MovimentacaoRequest movimentacaoRequest = new MovimentacaoRequest();
    movimentacaoRequest.setOrigem(669L);
    movimentacaoRequest.setDestino(657L);
    movimentacaoRequest.setValor(BigDecimal.valueOf(1L));

    TranInvoke invoke = tranClient.movimentacaoFinanceira(movimentacaoRequest, compassConfig);  -->NullPointer here
    return ResponseEntity.of(Optional.of(invoke), Optional.empty(), HttpStatus.SC_OK);
}

@Override
public void setup() {
    try {
        compassConfig = CompassConfig.build();
    } catch (InvalidConfigException e) {
        LOGGER.error("Compass config error", e);
    }
}
}

这是我的 pom.xml:

有人已经使用过这个配置吗？我添加了 spring-boot，因为它是进行 SOAP 调用的唯一方法。如果我尝试仅使用 WSDL 中的代码进行调用，当它尝试连接到服务器时，我收到一条错误消息，指出请求为空。使用 spring-boot，它不需要先连接，它只需发送请求即可正常工作。

欢迎任何帮助。

非常感谢。

显然，Spring Boot 应用程序上下文没有在您的代码中初始化...如果您确实想在 Lambda 函数中使用 Spring Boot，您可以尝试以下操作:

pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.RELEASE</version>
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-core</artifactId>
        <version>1.11.181</version>
    </dependency>
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-lambda-java-core</artifactId>
        <version>1.1.0</version>
    </dependency>
    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-lambda</artifactId>
        <version>1.11.181</version>
    </dependency>
</dependencies>

服务示例:

@Component
public class MyService {

    public void doSomething() {
        System.out.println("Service is doing something");
    }

}

一些 Bean 示例:

@Component
public class MyBean {

    @Autowired
    private MyService service;

    public void executeService() {
       service.doSomething();
    }

}

Lambda 处理程序示例:

@SpringBootApplication
public class LambdaHandler implements RequestHandler<Request, Response> {

    private ApplicationContext getApplicationContext(String [] args) {
        return new SpringApplicationBuilder(LambdaHandler.class)
                .web(false)
                .run(args);
    }

    public Response handleRequest(Request input, Context context) {
        ApplicationContext ctx = getApplicationContext(new String[]{});
        MyBean bean = ctx.getBean(MyBean.class);

        bean.executeService();

        return new Response();
    }
}
