Spring RestTemplate 415不支持的媒体类型

我正在尝试使用Spring Restful webservice。

我在两次日食中创建了两个项目。在一个项目中,我编写了RestClient程序,在另一个项目中,我编写了webservice,并在tomcat上查看了web服务。我试图将java bean作为客户端和服务器之间的json通信传递。

但是我得到了以下异常。

org.springframework.web.client.HttpClientErrorException: 415 Unsupported Media Type

我在很多方面尝试过,但没有成功。以下是我的代码段。

客户端方法:

private static void postTrack() {
        try {
            final String uri = "http://localhost:8181/RestWS/test";

            Track track = new Track();
            track.setTitle("Singer");
            track.setSinger("Shas");

            RestTemplate restTemplate = new RestTemplate();

            Track responseTrack = restTemplate.postForObject(uri, track, Track.class);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

服务方式:

@RequestMapping(value = "/test", method = RequestMethod.POST, headers = "Accept=application/json")
    public @ResponseBody Track testMethod(@RequestBody Track track) {
        System.out.println(" Inside Test Method : ");
        System.out.println(" In GreetingController.greeting() "+track.getSinger());
        return track;
    }

跟踪课程:

public class Track {

    String title;
    String singer;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getSinger() {
        return singer;
    }

    public void setSinger(String singer) {
        this.singer = singer;
    }

    @Override
    public String toString() {
        return "Track [title=" + title + ", singer=" + singer + "]";
    }
}

我也试过

restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

并且

MultiValueMap<String, String> header = new LinkedMultiValueMap<String, String>(); 
header.add("Content-Type", "application/json");           
HttpEntity<Object> httpEntity = new HttpEntity<Object>(track, header); 
ResponseEntity<Track> response = restTemplate.exchange(uri, HttpMethod.POST, httpEntity, Track.class);

答案 0 :(得分:2)

最后它的工作方式如下:

在servlet xml中添加了以下行。

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
    <property name="messageConverters"> 
        <list> 
            <ref bean="jsonConverter" /> 
        </list> 
    </property> 
</bean> 

<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> 
    <property name="supportedMediaTypes" value="application/json" /> 
</bean>

添加添加的jackson-core-2.5.0&amp; jackson-annotations-2.5.0罐子在类路径中。
