Question

我正在使用Spring MVC RESTful webservices＆amp;客户端是RestTemplate。通过使用jackson将json绑定到bean，一切正常，但是当我在bean中添加StringBuilder属性然后客户端获得异常

org.springframework.web.client.ResourceAccessException：POST请求的I / O错误＆＃34; http：//＆＃34;：服务器返回HTTP响应代码：415为URL：http：/ /嵌套异常是java.io.IOException：服务器返回HTTP响应代码：415为URL：http：//

引起：java.io.IOException：服务器返回HTTP响应代码：415为URL：http：//

请注意：在我的项目中，Bean拥有超过5000个具有嵌套，复杂和所有类型对象的属性   豆。我真的很难找到导致这个问题的原因   在一个嵌套对象中具有StringBuilder属性但它是不同的   从上面的例外。所以我不知道其他人是如何找到这种类型的   异常的问题与实际问题不同。

请求标头是：标头：{Accept = [application / json，application / * + json]，Content-Type = [application / json; charset = UTF-8]。一世   我在客户端和服务器上获得相同的请求标头。

请求正文： {＆＃34; id＆＃34;：＆＃34; 1＆＃34;，＆＃34; name＆＃34;：＆＃34; Shas＆＃34;，＆＃34; SB＆＃34;：空}

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;
    }

}

您是否可以提供您尝试访问的API的Accept和Content-Type标题？
