我收到的POST有问题。我有以下端点:
@RequestMapping(value = "/payment", method = POST)
public void saveOrder(@RequestBody PaymentDto paymentDto) throws RequiredFieldException, IOException, MessagingException {
//do something
}
现在,当有人向我发送此网址的POST时,我会收到以下回复:
{"errorMessage":"Unsupported Media Type",
"errorId":"906f5dc8-0b79-4f91-9eaa-a252e8d5ac76",
"errorDetails":
{"message":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported",
"exception":"org.springframework.web.HttpMediaTypeNotSupportedException",
"errors":null
}}
我该如何解决?发送时我无法更改内容类型标题。它是从我无法控制的服务器发送的。

到目前为止,对我来说最好的替代方法是编写一个转换器。
我选择这种方式的要点是:
application/x-www-form-urlencoded
的POST调用我的服务。第一:编写一个对象
package xx.xx.xx;
import java.io.Serializable;
public class MyObject implements Serializable {
private static final long serialVersionUID = -7474838713815803531L;
private String name;
private String id;
...
getters
setters
...
}
第二:创建一个转换器以映射模型
package xx.xx.xx;
import java.io.IOException;
import java.util.Map;
import org.springframework.http.HttpInputMessage;
import org.springframework.http.HttpOutputMessage;
import org.springframework.http.converter.AbstractHttpMessageConverter;
import org.springframework.http.converter.FormHttpMessageConverter;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.http.converter.HttpMessageNotWritableException;
import com.fasterxml.jackson.databind.ObjectMapper;
import xx.xx.xx.MyObject;
public class MyObjectConverter extends AbstractHttpMessageConverter<MyObject> {
private static final FormHttpMessageConverter formHttpMessageConverter = new FormHttpMessageConverter();
private static final ObjectMapper mapper = new ObjectMapper();
@Override
protected boolean supports(Class<?> clazz) {
return (MyObject.class == clazz);
}
@Override
protected MyObject readInternal(Class<? extends MyObject> clazz, HttpInputMessage inputMessage) throws IOException, HttpMessageNotReadableException {
Map<String, String> vals = formHttpMessageConverter.read(null, inputMessage).toSingleValueMap();
return mapper.convertValue(vals, MyObject.class);
}
@Override
protected void writeInternal(MyObject myObject, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException {
}
}
第三:告诉Spring使用此转换器
package xx.xx.xx;
import java.nio.charset.Charset;
import java.util.Arrays;
import java.util.List;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class HppResponseConverterDTOConfig implements WebMvcConfigurer {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(converter());
}
private MyObjectConverter converter() {
MyObjectConverter converter = new MyObjectConverter();
MediaType mediaType = new MediaType("application", "x-www-form-urlencoded", Charset.forName("UTF-8"));
converter.setSupportedMediaTypes(Arrays.asList(mediaType));
return converter;
}
}
奖金:此配置/实现处理属性内的下划线字符,换句话说:您可以使用@JsonProperty
注释,因为上面的实现使用ObjectMapper
并且对象Mapper(我认为)与春天用Content-type: application/json
序列化普通POST。
第四,最后:使用此实现:
package xx.xx.xx;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/my-object-controller")
public class MyObjectController {
@PostMapping(value = "/something", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public void doSomething(@RequestBody MyObject myObject) {
doSomethingWithMyObject(myObject);
}
}
我希望这会有所帮助:)

实际上,有助于将@RequestBody
更改为@ModelAttribute
。所以我的代码看起来像那样:
@RequestMapping(value = "/payment", method = POST)
public void saveOrder(@ModelAttribute PaymentDto paymentDto) throws RequiredFieldException, IOException, MessagingException {
//do something
}

如果Content Type是application / json或application / xml使用@RequestBody注释,如果是application / x-www-form-urlencoded则使用@ModelAttribute
