Spring REST Jackson-StringBuilder未与JSON绑定

Question

我正在使用Spring MVC RESTful Web服务

组织。springframework。网状物客户ResourceAccessException:POST请求“http://”时发生I/O错误：服务器返回了URL:http://嵌套异常为java的http响应代码：415。伊奥。IOException:服务器返回了URL:HTTP:的HTTP响应代码：415//

原因：java。伊奥。IOException:服务器返回了URL:HTTP:的HTTP响应代码：415//

请注意：在我的项目中，Bean有5000多个属性，其中包含嵌套的、复杂的和所有类型的对象。实际上，我很难发现这个问题，因为在一个嵌套对象中有StringBuilder属性，但它与上面的异常不同。所以我不知道其他人是如何发现这些问题的，因为例外和实际问题是不同的。

请求头是：头：{Accept=[application/json，application/*json]，Content Type=[application/json；charset=UTF-8]。我在客户端和服务器上都得到了相同的请求头。

请求正文：{“id”：“1”，“name”：“Shas”，“sb”：null}

如果有人有解决方案，请分享。

客户端：

final String uri = "http://localhost:8282/WS/rest/add";
RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<ClientHttpRequestInterceptor>();
interceptors.add(new LoggingRequestInterceptor());
restTemplate.setInterceptors(interceptors);
Person person = new Person();
person.setId("1");
person.setName("Siva");
restTemplate.postForObject(uri, person, Person.class);

服务器端：

@RequestMapping(value = "/add", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody Person addPerson(@RequestBody final Person person) {
        try {
            if (person != null) {
                System.out.println("Person ID : "+person.getId());
            } else {
                System.out.println("Request Obj is null at ws controller");
            }
        } catch(Exception e) {
            e.printStackTrace();
        }
        return person;
}

Person.java

public class Person implements Serializable {

    private static final long serialVersionUID = 1L;

    private String id = null;
    private String name = null;
    private StringBuilder sb = null;

    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public StringBuilder getSb() {
        return sb;
    }
    public void setSb(StringBuilder sb) {
        this.sb = sb;
    }
    public static long getSerialversionuid() {
        return serialVersionUID;
    }

}

你能提供你想要点击的API的Accept和Content-Type标题吗？
