There is app on spring+jaxb+jpa

So, I have rest - controllers and jaxv Elements:

@AllArgsConstructor

@NoArgsConstructor

@XmlRootElement(name = "root")

@Getter

public class UserWrapper {

    @XmlElementWrapper(name = "Users")

    @XmlElement(name = "User")

    private List<User> Users;



    @XmlElement(name="UserError")

    private UserError error;

}





@Getter

@Setter

@XmlRootElement(name="User")

@NoArgsConstructor

public class User{

  @XmlElement

  private String name;

  @XmlElement

  private String surname;

}

There are User entity and Wrapper for contain List of Users.

Response from my controller is:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<root>

    <Users>

        <User>

            <Name>AAA</Name>

            <Surname>AAA</Surname>

        </User>

        <User>

            <Name>BBB</Name>

            <Surname>BBB</Surname>

        </User>

    </Users>

</root>

How to make response without tag ?

Rest controller is:

@RequestMapping(value = "/users", method = RequestMethod.GET)

    public @ResponseBody UsersWrapper findByParams(

            @RequestParam(value = "id") String id) throws Exception {

        RiskMetricError error = null;

        List<User> users = userService.find(id);



        return (new UsersWrapper(users, error));

    }

P.S.
I need to make response xml like this:

        <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

        <Users>

            <User>

                <Name>AAA</Name>

                <Surname>AAA</Surname>

            </User>

            <User>

                <Name>BBB</Name>

                <Surname>BBB</Surname>

            </User>

        </Users>

Comparing the two xmls (actual vs desired) you do not want to have the users content within the <root>. You can do this:

@XmlRootElement(name = "Users")

@NoArgsConstructor

@AllArgsConstructor

@XmlAccessorType(XmlAccessType.FIELD)

public class Users {



    @XmlElement(name = "User")

    private List<User> users;

}

Then User will be:

@Getter

@Setter

@NoArgsConstructor

@AllArgsConstructor

@XmlAccessorType(XmlAccessType.FIELD)

public class User {



    @XmlElement(name = "Name")

    private String name;

    @XmlElement(name = "Surname")

    private String surname;

}

A small spring boot application to try it out:

@RestController

public class UsersEndpoint {



    @GetMapping("/users")

    public Users getUsers() {

        List<User> users = new ArrayList<>();

        users.add(new User("name1", "surname1"));

        users.add(new User("name2", "surname2"));



        return new Users(users);

    }

}

Will return this:

<Users>

    <User>

        <Name>name1</Name>

        <Surname>surname1</Surname>

    </User>

    <User>

        <Name>name2</Name>

        <Surname>surname2</Surname>

    </User>

</Users>

Update to reply to comment (elaborate on the answer):

Your POJOs and your xml structure should match. The annotations help "smooth" differences. You had <root></root> because your root class UserWrapper had this annotation: @XmlRootElement(name = "root"). If in the name you had "blah" the external tags (<root></root>) would be <blah></blah>. Additionally above your list of users you had this annotation: @XmlElementWrapper(name = "Users"). This created an extra wrapper element outside your list elements with the provided name.

So what I did is properly name the root element and remove the extra wrapper element creation.
