java - 错误 Java Jersey com.sun.jersey.spi.inject.Errors$ErrorMessagesException 在 com.sun.jersey.spi.inject.Errors.processErrorMessages(Errors.java :170)

Question

我在java类中有两个方法，它们被定义为包含以下方法的 Jersey 资源

@Path("base_endpoint")
public class ComplaintSupportResource{

    @Post
    @Path("/endPoint")
    @Consumes({MediaType.APPLICATION_JSON})
    @Produces({MediaType.APPLICATION_JSON})
    public Response complaintRegister(ComplaintDTO caliamtDTO) {
        ComplaintResponseDTO response =complaintService.registerComplaint(caliamtDTO);
        return Response.ok(response).build();
    }
}

这是 dto 类:

@XmlRootElement公共(public)类 ComplaintDTO {

private String memberName;
private String email;
private String mobileNO;
private String complaintId;
private String claimNo;
private String complaintDetails;
private String policyNo;



public String getComplaintId() {
    return complaintId;
}
public void setComplaintId(String complaintId) {
    this.complaintId = complaintId;
}
public String getClaimNo() {
    return claimNo;
}
public void setClaimNo(String claimNo) {
    this.claimNo = claimNo;
}
public String getComplaintDetails() {
    return complaintDetails;
}
public void setComplaintDetails(String complaintDetails) {
    this.complaintDetails = complaintDetails;
}
public String getPolicyNo() {
    return policyNo;
}
public void setPolicyNo(String policyNo) {
    this.policyNo = policyNo;
}
public String getMemberName() {
    return memberName;
}
public void setMemberName(String memberName) {
    this.memberName = memberName;
}
public String getEmail() {
    return email;
}
public void setEmail(String email) {
    this.email = email;
}
public String getMobileNO() {
    return mobileNO;
}
public void setMobileNO(String mobileNO) {
    this.mobileNO = mobileNO;
}
}

我收到以下异常。我不确定我做错了什么。

    SEVERE: A sub-resource locator, public javax.ws.rs.core.Response com.xxx.xxx.xxxComplaintSupportResource.complaintRegister(com.xxx.xxx.xxx.ComplaintDTO), can not have an entity parameter. Try to move the parameter to the corresponding resource method.

下面的实现有什么问题。我还实现了其他端点，它们工作正常。

Answer 1

@Post 注释不正确，可能是您从其他库导入，它们 Jerysey @POST 注释是不同的，并确保您正在导入 javax.ws.rs.POST。将@Post 更改为@POST，如下所示:

   @Path("base_endpoint")
   public class ComplaintSupportResource{

    **@POST**
    @Path("/endPoint")
    @Consumes({MediaType.APPLICATION_JSON})
    @Produces({MediaType.APPLICATION_JSON})
    public Response complaintRegister(ComplaintDTO caliamtDTO) {
        ComplaintResponseDTO response =complaintService.registerComplaint(caliamtDTO);
        return Response.ok(response).build();
    }
}
