錯誤 Java Jersey com.sun.jersey.spi.inject.Errors$ErrorMessagesException at com.sun.jersey.spi.inject.Errors.processErrorMessages(Errors.java:170)

Question

我在java類中有兩個方法，它們被定義為包含以下方法的球衣資源

@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();
    }
}

這是 dto 類：

@XmlRootElement 公共類 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;
}
}

我收到以下異常。 我不確定我做錯了什么。

    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.

下面的實現有什么問題。 我還有其他端點也實現了我同樣工作正常。

Answer 1

@Post 注釋不正確可能是您從其他一些庫中導入它們 Jerysey @POST 注釋不同並確保您正在導入 javax.ws.rs.POST。 將@Post 更改為@POST，例如：

   @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();
    }
}

Answer 2

您能否檢查構建路徑中是否存在以下依賴項

jersey-multipart.jar
mimepull.jar

如果沒有，請嘗試將它們添加到類路徑。

其他可能的原因可能是，相同的 @Path 注釋 - @Path("/endPoint") with uri as "/endpoint" 可能被定義兩次。

希望這可以幫助你。
