接受来自Ruby的字符串和XML数据
接受来自Ruby的字符串和XML数据
提问于 2018-09-05 17:11:28
我想创建REST服务器，它接受来自Ruby代码的XML请求和纯文本到不同的控制器中。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);
}
}
}如您所见，在某些方法中，我接收XML，而在其他方法中，我接收key=value&.....形式的字符串
如何将Spring配置为同时接受这两种类型？另外，我是否应该将Rest控制器拆分成不同的文件？
编辑：
示例XML请求：
<?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>示例XML响应：
<?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>通知请求示例：
uniqueid=23434&type=sale&status=33示例通知响应:它应该只返回HTTP status OK。
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")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
