以下是错误分析:

自定义的封装类如下:

public class ResultData {
    private boolean result=false;
    private String message;
    private T data;
}

发布webservice的类的方法如下:

 public ResultData startProcessInstance(ProcessInstanceStartRequest request){
        ProcessInstanceResponse data=new ProcessInstanceResponse();
       //此处简略书写
        ResultData resultData=new ResultData();
        resultData.setResult(result);
        resultData.setMessage(message);
        resultData.setData(data);
        return resultData;

    }

错误原因:因为setData的方法的入参用的是泛型T,无法解析ProcessInstanceResponse类。

解决:在自定义类ResultData添加:@XmlSeeAlso({A.class, B.class})

//ProcessInstanceResponse和PageResponse是用到的要解析的类,可以继续添加其他的解析类
@Data
@XmlSeeAlso({ProcessInstanceResponse.class, PageResponse.class})
public class ResultData {
    private boolean result=false;
    private String message;
    private T data;
}
