杰克逊 + Jersey 返回根名称为“List”的列表

Question

我目前正在尝试创建一个使用 Jackson 和 Jersey 序列化 POJO 对象的系统，这里是我的资源：

@Path("/OrganicasFuncao")

public class OrganicasFuncaoResource {

public OrganicasFuncaoResource() {
    // TODO Auto-generated constructor stub
}

@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("/getAllOrganicasFuncao")

public List<OrganicaFuncaoMobileEntity> getOrganicasFuncao(){

     List<OrganicaFuncaoMobileEntity> organicas; organicas= new ArrayList<OrganicaFuncaoMobileEntity>();

    //dummy data
    organicas.add(fillOrganicaFuncao(111,123,"Função Assim","2010-12-23"));
    organicas.add(fillOrganicaFuncao(113,124,"Função Assada","2000-05-21"));
    organicas.add(fillOrganicaFuncao(113,125,"Função Meio termo","2002-12-23"));
    organicas.add(fillOrganicaFuncao(112,126,"Função Mal Passada","2011-06-14"));
    organicas.add(fillOrganicaFuncao(112,127,"Função Bem Passada","2006-02-01"));
    organicas.add(fillOrganicaFuncao(111,128,"Função Crua","2003-04-07"));
    organicas.add(fillOrganicaFuncao(113,127,"Função Queimadinha","2006-02-01"));
    organicas.add(fillOrganicaFuncao(113,128,"Função Tostada","2003-04-07"));


    return organicas;
}

private OrganicaFuncaoMobileEntity fillOrganicaFuncao(int id, int idOrg, String designacao, String dataAlteracao){

    OrganicaFuncaoMobileEntity orgFunc= new OrganicaFuncaoMobileEntity();
    orgFunc.setDataAlteracao(dataAlteracao);
    orgFunc.setDesignacao(designacao);
    orgFunc.setId(id);
    orgFunc.setIdOrganica(idOrg);

    return orgFunc;
}

}

这返回：

{ “列表” ： [ { "designacao" : "Função Assim", “id有机”：123， "dataAlteracao" : "2010-12-23", “ID”：111 }, { "designacao" : "Função Assada", “id有机”：124， "dataAlteracao" : "2000-05-21", “ID”：113 }, { "designacao" : "Função Meio termo", “id有机”：125， "dataAlteracao" : "2002-12-23", “ID”：113 }, { "designacao" : "Função Mal Passada", “id有机”：126， "dataAlteracao" : "2011-06-14", “ID”：112 }, { "designacao" : "Função Bem Passada", “id有机”：127， "dataAlteracao" : "2006-02-01", “ID”：112 }, { "designacao" : "Função Crua", “id有机”：128， "dataAlteracao" : "2003-04-07", “ID”：111 }, { "designacao" : "Função Queimadinha", “id有机”：127， "dataAlteracao" : "2006-02-01", “ID”：113 }, { "designacao" : "Função Tostada", “id有机”：128， "dataAlteracao" : "2003-04-07", “ID”：113 }] 我如何

用我自己的一些名称更改“列表”名称？我尝试使用几个注释，如 @jsonTypeName 或 @jsonTypeInfo，但这不起作用......

添加 Jackson 的依赖项。 Jackson 是 Jersey 支持的一个很好的 JSON 序列化器/反序列化器。它不需要对序列化/反序列化类进行任何注释，只需将它们定义为“结构”：

public class Person {
    public String name;
    public int age;
}

如果您让字段为 public，则不需要 getter 和 setter。您需要的依赖项可以在这里找到： http://mvnrepository.com/ search.html?query=com.fasterxml.jackson.core。无需额外配置，Jersey 会检测它是否在类路径上。

您遇到的问题可能是由 Jerseys 默认 OOTB JSON 序列化/反序列化引起的。
