接受Ruby中的字符串和XML数据

Question

我想创建REST服务器，它接受XML请求和从Ruby代码到不同控制器的纯文本。我试图实现这一点：

@SpringBootApplication
public class Application extends SpringBootServletInitializer implements WebMvcConfigurer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    ..............

    @Override
    public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.removeIf(converter -> converter instanceof MappingJackson2XmlHttpMessageConverter);
        converters.removeIf(converter -> converter instanceof MappingJackson2HttpMessageConverter);
        converters.add(new MappingJackson2XmlHttpMessageConverter(
                ((XmlMapper) createObjectMapper(Jackson2ObjectMapperBuilder.xml()))
                        .enable(ToXmlGenerator.Feature.WRITE_XML_DECLARATION)));
        converters.add(new MappingJackson2HttpMessageConverter(createObjectMapper(Jackson2ObjectMapperBuilder.json())));
    }

    private ObjectMapper createObjectMapper(Jackson2ObjectMapperBuilder builder) {
        builder.indentOutput(true);
        builder.modules(new JaxbAnnotationModule());
        builder.serializationInclusion(JsonInclude.Include.NON_NULL);
        builder.defaultUseWrapper(false);
        return builder.build();
    }    
}

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        //MyRequestBodyHttpMessageConverter converter = new MyRequestBodyHttpMessageConverter();
        FormHttpMessageConverter converter = new FormHttpMessageConverter();
        //MediaType utf8FormEncoded = new MediaType("application","x-www-form-urlencoded", Charset.forName("UTF-8"));
        //MediaType mediaType = MediaType.APPLICATION_FORM_URLENCODED; maybe UTF-8 is not needed
        converter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_FORM_URLENCODED));
        //converter.setSupportedMediaTypes(Arrays.asList(utf8FormEncoded));
        converters.add(converter);
        MappingJackson2HttpMessageConverter conv1 = new MappingJackson2HttpMessageConverter();
        conv1.getObjectMapper().registerModule(new JaxbAnnotationModule());
        converters.add(conv1);

        MappingJackson2XmlHttpMessageConverter conv = new MappingJackson2XmlHttpMessageConverter();
        // required by jaxb annotations
        conv.getObjectMapper().registerModule(new JaxbAnnotationModule());
        converters.add(conv);
    }
}

检查XML格式是否正确：

@ControllerAdvice
public class RestExceptionHandler extends ResponseEntityExceptionHandler {

    @Override
    protected ResponseEntity<Object> handleHttpMessageNotReadable(HttpMessageNotReadableException ex,
                                                                  HttpHeaders headers, HttpStatus status, WebRequest request) {
        PaymentTransaction response;
        if (ex.getMessage().contains("Required request body")) {
            response = new PaymentTransaction(PaymentTransaction.Response.failed_response, 350,
                    "Invalid XML message: No XML data received", "XML request parsing failed!");
        } else {
            response = new PaymentTransaction(PaymentTransaction.Response.failed_response, 351,
                    "Invalid XML message format", null);
        }
        return ResponseEntity.badRequest().body(response);
    }
}

控制器类：

@RestController()
public class HomeController {

    @Autowired
    public HomeController(Map<String, MessageProcessor> processors, Map<String, ReconcileProcessor> reconcileProcessors,
            @Qualifier("defaultProcessor") MessageProcessor defaultProcessor,
            AuthenticationService authenticationService, ClientRepository repository,
            @Value("${request.limit}") int requestLimit) {
        // Here I receive XML 
    }

    @GetMapping(value = "/v1/*")
    public String message() {
        return "REST server";
    }

    @PostMapping(value = "/v1/{token}", consumes = { MediaType.APPLICATION_XML_VALUE,
            MediaType.APPLICATION_JSON_VALUE }, produces = { MediaType.APPLICATION_XML_VALUE,
                    MediaType.APPLICATION_JSON_VALUE })
    public PaymentResponse handleMessage(@PathVariable("token") String token,
            @RequestBody PaymentTransaction transaction, HttpServletRequest request) throws Exception {
        // Here I receive XML 
    }

    @PostMapping(value = "/v1/notification")
    public ResponseEntity<String> handleNotifications(@RequestBody Map<String, String> keyValuePairs) {
         // Here I receive key and value in request body
    }

    @PostMapping(value = "/v1/summary/by_date/{token}", consumes = { MediaType.APPLICATION_XML_VALUE,
            MediaType.APPLICATION_JSON_VALUE }, produces = { MediaType.APPLICATION_XML_VALUE,
                    MediaType.APPLICATION_JSON_VALUE })
    public PaymentResponses handleReconcile(@PathVariable("token") String token, @RequestBody Reconcile reconcile,
            HttpServletRequest request) throws Exception {
         // Here I receive XML 
    }

    @ResponseStatus(value = HttpStatus.UNAUTHORIZED)
    public static class UnauthorizedException extends RuntimeException {
        UnauthorizedException(String message) {
            super(message);
        }
    }
}

<?xml version="1.0" encoding="UTF-8"?>
<payment_transaction>
  <transaction_type>authorize</transaction_type>
  <transaction_id>2aeke4geaclv7ml80</transaction_id>
  <amount>1000</amount>
  <currency>USD</currency>
  <card_number>22</card_number>
  <shipping_address>
    <first_name>Name</first_name>    
  </shipping_address>
</payment_transaction>

<?xml version="1.0" encoding="UTF-8"?>
<payment_response>
    <transaction_type>authorize</transaction_type>
    <status>approved</status>
    <unique_id>5f7edd36689f03324f3ef531beacfaae</unique_id>
    <transaction_id>asdsdlddea4sdaasdsdsa4dadasda</transaction_id>
    <code>500</code>
    <amount>101</amount>
    <currency>EUR</currency>
</payment_response>

uniqueid=23434&type=sale&status=33

我使用：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
        <relativePath />
    </parent>

Java版本：“10.0.2”2018-07-17和Wildfly 13。

关于我使用的XML生成：

@XmlRootElement(name = "payment_transaction")
public class PaymentTransaction {

    public enum Response {
        failed_response, successful_response
    }

    @XmlElement(name = "transaction_type")
    public String transactionType;
    @XmlElement(name = "transaction_id")
    public String transactionId;
    @XmlElement(name = "usage")

Answer 1

在WildFly上作为WAR应用程序部署时，Sun.Reflect包中包含的Spring Boot应用程序可能需要一些高级JDK反射API来进行代理。为此，您的应用程序需要在其manifest.mf文件中将jdk.unsupported作为依赖项列出（请参见WildFly wiki）。

源码-所以我首先应用了这个。

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>3.2.2</version>
    <configuration>
        <packagingExcludes>WEB-INF/web.xml</packagingExcludes>
        <archive>
            <manifestEntries>
                <Dependencies>jdk.unsupported</Dependencies>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>

接下来，我修复了日志记录：我将这里接受的答案的第一个注释应用于日志记录，并从这里向src/main/resources添加了一个基本的logback.xml。

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclude-subsystems>
            <subsystem name="logging" />
        </exclude-subsystems>
    </deployment>
</jboss-deployment-structure>

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclude-subsystems>
            <subsystem name="logging" />
        </exclude-subsystems>
        <dependencies>
            <module name="org.reactivestreams"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

您必须将该文件放到src/main/webapp/WEB-INF目录中。

如果您需要使用与application/x-www-form-urlencoded不同的支持内容类型，您可以通过将适当的MessageConverter注册到您的内容类型来完成。

在您的情况下，由于请求正文中有querystring，FormHttpMessageConverter将是“正确的”，您必须将内容类型指定为MY_OTHER_CONTENT_TYPE常量：

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    FormHttpMessageConverter converter = new FormHttpMessageConverter();
    MediaType utf8FormEncoded = new MediaType("application","x-www-form-urlencoded", Charset.forName("UTF-8"));
converter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_FORM_URLENCODED, MY_OTHER_CONTENT_TYPE));
    converters.add(converter);
    super.configureMessageConverters(converters);
}
