我需要将请求发送到服务并将响应解析为jaxb对象。这是服务呼叫代码:
ProviderResponse response = restTemplate.postForObject(
URL,
request,
ProviderResponse.class
);
request
和response
是JAXB对象。这是弹簧配置:<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
<bean class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller" ref="jaxbMarshaller"/>
<property name="unmarshaller" ref="jaxbMarshaller"/>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>com.service.data.ProviderRequest</value>
<value>com.service.data.ProviderResponse</value>
</list>
</property>
</bean>
运行此代码时,出现异常:
org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [class com.service.data.ProviderResponse] and content type [application/octet-stream]
我试图这样做:
String responseStr = restTemplate.postForObject(
URL,
request,
String.class
);
ProviderResponse response = stringToJaxb(responseStr, ProviderResponse.class);
而且效果很好,但我认为这不是一个好的解决方案。
也许可以通过spring config来解决?
UPD
ProviderResponse类:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"header",
"body"
})
@XmlRootElement(name = "providerResponse")
public class ProviderResponse {
@XmlElement(required = true)
protected String header;
@XmlElement(required = true)
protected ProviderResponse.Body body;
public String getHeader() {
return header;
}
public void setHeader(String value) {
this.header = value;
}
public ProviderResponse.Body getBody() {
return body;
}
public void setBody(ProviderResponse.Body value) {
this.body = value;
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"code",
"serviceStatus"
})
public static class Body {
@XmlElement(required = true)
protected String code;
protected String serviceStatus;
public String getCode() {
return code;
}
public void setCode(String value) {
this.code = value;
}
public String getServiceStatus() {
return serviceStatus;
}
public void setServiceStatus(String value) {
this.serviceStatus = value;
}
}
}
最佳答案
对于RestTemplate,它不使用在应用程序上下文中配置的转换器。您必须创建一个HttpMessageConverters列表,并在RestTemplate构造函数中提供它,如下所示
MarshallingHttpMessageConverter marshallingConverter = new MarshallingHttpMessageConverter();
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setClassesToBeBound(ProviderRequest.class ,ProviderResponse.class);
marshallingConverter.setMarshaller(marshaller);
marshallingConverter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_OCTET_STREAM , MediaType.APPLICATION_XML , MediaType.TEXT_XML));
RestTemplate restTemplate = new RestTemplate(Collections.singletonList(converter));
