Question

以下是我的POJO课程

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;
}

}

以下是我的资源类

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

但即使这样我也会收到错误＆＃39; 获取HTTP状态415 - 不支持的媒体＆＃39;

你能成像吗，我哪里出错？

Answer 1

我看到你有MOXy。但是MOXy只知道如何处理用@XmlRootElement注释的类。这就是415的原因：泽西岛找不到MessageBodyReader来处理这种类型。

在@XmlRootElement类之上添加Credentials后，您将收到另一个错误，因为MOXy无法将JSON实际反序列化为Credentials。原因是没有默认（no-arg）构造函数。所以补充说，我认为你应该做得好。

获取HTTP状态415 - 使用Jersey不支持的媒体类型
