我正在准备一个OSGiR7、OpenAPI和jsonSchema的简短REST演示。一切正常，除了邮递员给出以下错误：

No message body writer has been found for class com.ovloop.masterdata.party.pojo.provider.Person, ContentType: application/json
我实现Restful服务的类编写如下。顺便说一句，我可以在这个类上运行swagger maven插件并获得相应的swagger规范

public class PersonRestImpl {

    @GET
    @Path("/person")
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(summary = "Get person with key", description = "Get person with key")
    public Person getPerson(@PathParam("person") Long personId) {
        Person person = new Person();
        person.setPersonId("3245234");
        person.setFirstName("Tom");
        person.setLastName("Petty");
        person.setAge(65);

        return person;
    }

    @GET
    @Path("/persons")
    @Operation(summary = "Get persons", description = "Get list of persons")
    public Response getPersons() {
        Person person = new Person();
        person.setPersonId("3245234");
        person.setFirstName("Tom");
        person.setLastName("Petty");
        person.setAge(65);

        List<Person> persons = new ArrayList<Person>();
        persons.add(person);

        Gson jsonConverter = new GsonBuilder().create();
        return Response.status(Status.ACCEPTED).entity(jsonConverter.toJson(persons)).build();
    }

    @DELETE
    @Path("/delete")
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(summary = "delete person", description = "delete person")
    public boolean deletePerson(@PathParam("person") long personId) {
        return true;
    }

    @POST
    @Path("/create")
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(summary = "Create Person", description = "Create Person")
    public Person postPerson(Person person) {
//      if (person.personId > 0) {
//          personDao.update(person);
//          return person;
//      } else {
//          long id = personDao.save(person);
//          person.personId = 1;
//          return person;
//      }

        return person;

    }
}
但是，如上所述，在运行这个简单的应用程序时，Postman在调用getPerson方法时给了我以下错误：

No message body writer has been found for class com.ovloop.masterdata.party.pojo.provider.Person, ContentType: application/json
但是，当我将响应类型从Person替换为response并手动生成JSON时，一切都很好：

@GET
    @Path("/person")
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(summary = "Get person with key", description = "Get person with key")
    public Response getPerson(@PathParam("person") Long personId) {
        Person person = new Person();
        person.setPersonId("3245234");
        person.setFirstName("Tom");
        person.setLastName("Petty");
        person.setAge(65);

        Gson jsonConverter = new GsonBuilder().create();
        return Response.status(Status.ACCEPTED).entity(jsonConverter.toJson(person)).build();
    }
不幸的是，这将Person数据类型排除在我生成的swagger规范之外，这是不好的

所以我的问题是如何在OSGi应用程序中为自定义POJO注册消息体编写器

提前感谢您的反馈

Paul提到了注册JacksonJsonProvider。我的印象是，将fasterxml的jackson提供程序作为必需的捆绑包添加就可以了。相反，我把它换成了org.apache.aries.jax.rs.jackson，这一切都成功了

你需要注册JacksonJsonProvider。我从未使用过OSGI。是否没有应用程序配置？你所拥有的只是资源类？ 
@GET
    @Path("/person")
    @Produces(MediaType.APPLICATION_JSON)
    @Operation(summary = "Get person with key", description = "Get person with key")
    public Response getPerson(@PathParam("person") Long personId) {
        Person person = new Person();
        person.setPersonId("3245234");
        person.setFirstName("Tom");
        person.setLastName("Petty");
        person.setAge(65);

        Gson jsonConverter = new GsonBuilder().create();
        return Response.status(Status.ACCEPTED).entity(jsonConverter.toJson(person)).build();
    }
