java - 获取HTTP状态415- Jersey 不支持的媒体类型

以下是我的POJO课

public class Credentials {
private int cred_id;
private String cred_user_name;
private String cred_password;
private String cred_token;

public Credentials(int cred_id, String cred_user_name,
        String cred_password, String cred_token) {
    this.cred_id = cred_id;
    this.cred_user_name = cred_user_name;
    this.cred_password = cred_password;
    this.cred_token = cred_token;
}

public int getCred_id() {
    return cred_id;
}

public void setCred_id(int cred_id) {
    this.cred_id = cred_id;
}

public String getCred_user_name() {
    return cred_user_name;
}

public void setCred_user_name(String cred_user_name) {
    this.cred_user_name = cred_user_name;
}

public String getCred_password() {
    return cred_password;
}

public void setCred_password(String cred_password) {
    this.cred_password = cred_password;
}

public String getCred_token() {
    return cred_token;
}

public void setCred_token(String cred_token) {
    this.cred_token = cred_token;
}

}

以下是我的资源班

public class ValidateUser {
@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public String validateUser(Credentials credentials) {
    System.out.println("Going to validate the user" + credentials);
    String username = credentials.getCred_user_name();
    String password = credentials.getCred_password();
    CredentialsAccessor ca = new CredentialsAccessor();
    long count = 0;
    count = ca.authenticateUser(username, password);
    if (count > 0) {
        JSONObject jObject = new JSONObject();
        try {
            jObject.put("valid", "true");
            return jObject.toString();
        } catch (JSONException e) {
            e.printStackTrace();
            return "{'valid':'error'}";
        }
    } else {
        JSONObject jObject = new JSONObject();
        try {
            jObject.put("valid", "false");
            return jObject.toString();
        } catch (JSONException e) {
            e.printStackTrace();
            return "{'valid':'error'}";
        }
    }
}

}

我确保在RESTClient中，我将内容类型指定为Content-Type:application / json

Please see the RESTClient

下面是我的web.xml

但是即使如此，我仍然收到错误信息“，获取HTTP状态415-不支持的媒体”

你能想象，我要去哪里错了？

最佳答案

我看到你有MOXy。但是MOXy只知道如何处理带有@XmlRootElement注释的类。这就是415的原因:泽西岛无法找到MessageBodyReader来处理该类型。

在@XmlRootElement类的顶部添加Credentials之后，您将遇到另一个错误，因为MOXy无法将JSON反序列化为您的Credentials。原因是没有默认的(无参数)构造函数。因此，加上这一点，我认为您应该很好。
