我有一个Company实体，每次我添加一个公司，我都会出错，我用PostgreSQL做我的数据库，我用双引号来Mappascalcase中的表的列。
公司实体：

@Entity
@XmlRootElement
public class Company {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name="\"Id\"")
    private Long id;
    @Column(name="\"Name\"")
    private String name;
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

公司端点：

@Stateless
@Path("/companies")
public class CompanyEndpoint {
    @PersistenceContext(unitName = "primary")
    private EntityManager em;

    @POST
    @Consumes("application/json")
    public Response create(Company entity) {
        em.persist(entity);
        return Response.created(
                UriBuilder.fromResource(CompanyEndpoint.class)
                        .path(String.valueOf(entity.getId())).build()).build();
    }

    @DELETE
    @Path("/{id:[0-9][0-9]*}")
    public Response deleteById(@PathParam("id") Long id) {
        Company entity = em.find(Company.class, id);
        if (entity == null) {
            return Response.status(Status.NOT_FOUND).build();
        }
        em.remove(entity);
        return Response.noContent().build();
    }

    @GET
    @Path("/{id:[0-9][0-9]*}")
    @Produces("application/json")
    public Response findById(@PathParam("id") Long id) {
        TypedQuery<Company> findByIdQuery = em
                .createQuery(
                        "SELECT DISTINCT c FROM Company c WHERE c.id = :entityId ORDER BY c.id",
                        Company.class);
        findByIdQuery.setParameter("entityId", id);
        Company entity;
        try {
            entity = findByIdQuery.getSingleResult();
        } catch (NoResultException nre) {
            entity = null;
        }
        if (entity == null) {
            return Response.status(Status.NOT_FOUND).build();
        }
        return Response.ok(entity).build();
    }

    @GET
    @Produces("application/json")
    public List<Company> listAll(@QueryParam("start") Integer startPosition,
            @QueryParam("max") Integer maxResult) {
        TypedQuery<Company> findAllQuery = em
                .createQuery("SELECT DISTINCT c FROM Company c ORDER BY c.id",
                        Company.class);
        if (startPosition != null) {
            findAllQuery.setFirstResult(startPosition);
        }
        if (maxResult != null) {
            findAllQuery.setMaxResults(maxResult);
        }
        final List<Company> results = findAllQuery.getResultList();
        return results;
    }

    @PUT
    @Path("/{id:[0-9][0-9]*}")
    @Consumes("application/json")
    public Response update(@PathParam("id") Long id, Company entity) {
        if (entity == null) {
            return Response.status(Status.BAD_REQUEST).build();
        }
        if (id == null) {
            return Response.status(Status.BAD_REQUEST).build();
        }
        if (!id.equals(entity.getId())) {
            return Response.status(Status.CONFLICT).entity(entity).build();
        }
        if (em.find(Company.class, id) == null) {
            return Response.status(Status.NOT_FOUND).build();
        }
        try {
            entity = em.merge(entity);
        } catch (OptimisticLockException e) {
            return Response.status(Response.Status.CONFLICT)
                    .entity(e.getEntity()).build();
        }

        return Response.noContent().build();
    }
}

我最后看到的是org.postgresql.util.PSQLException: The column name "Id" was not found in this ResultSet.
有人能解释一下我的代码中有什么错误吗？提前谢谢你。

我想你的程序会查找一个名为“Id”的列，而不是“Id”。你应该这样修改你的注解。

@Column(name="Id")
private Long id;

我会说西班牙语，这个答案我用谷歌翻译：它给我标上了同样的错误，但是是用java，原因是通过rs发送了一个不在select查询中的值，例如（"SELECT DISTINCT c FROM Company c ORDER BY c.id ", Company.class);）。可能id在列中拼写错误，因为当想要将该数据传递给另一个元素时找不到它，所以它标上了错误。
这是我代码：

String sql = "select p.nombre_paciente, p.apellido_paciente, p.nacimiento_paciente, p.edad_paciente, p.cedula_paciente, p.profesion_paciente,p.dlaboral_paciente,p.dparticular_paciente,p.tlaboral_paciente,p.tparticular_paciente,c.idcivil,c.tipo,**p.id_paciente** from paciente p inner join civil c on p.idcivil = c.idcivil where upper(nombre_paciente) like '%" + nombre.toUpperCase() + "%'"
                    + " order by id_paciente offset " + offset + " limit " + utiles.Utiles.REGISTROS_PAGINA;
    System.out.println("--->" + sql);
    try (PreparedStatement ps = Conexion.getConn().prepareStatement(sql)) {
        ResultSet rs = ps.executeQuery();
        String tabla = "";
        while (rs.next()) {
            tabla += "<tr>"
            + "<td>" + rs.getInt("id_paciente") + "</td>"
            + "<td>" + rs.getString("nombre_paciente") + "</td>"
            + "<td>" + rs.getString("apellido_paciente") + "</td>"
            + "<td>" + rs.getDate("nacimiento_paciente") + "</td>"
            + "<td>" + rs.getInt("edad_paciente") + "</td>"
            + "<td>" + rs.getString("cedula_paciente") + "</td>"
            + "<td>" + rs.getString("profesion_paciente") + "</td>"
            + "<td>" + rs.getString("dlaboral_paciente") + "</td>"
            + "<td>" + rs.getString("dparticular_paciente") + "</td>"
            + "<td>" + rs.getString("tlaboral_paciente") + "</td>"
            + "<td>" + rs.getString("tparticular_paciente") + "</td>"
            + "<td>" + rs.getInt("idcivil") + "</td>"
            + "<td>" + rs.getString("tipo") + "</td>"
            + "</tr>";

用粗体标记的内容不存在，当实现它时，错误消失了。Ps .：我知道你发了很多短信
