运行时异常不可序列化

Question

SEVERE: Servlet.service() for servlet [Jersey Web Application] in context with path *** threw exception
[javax.ws.rs.ProcessingException: Error deserializing object from entity stream.] with root cause

当我抛出运行时异常时，在 Jax-rs 中抛出异常。

我有一个抛出运行时异常的普通函数。我想用异常映射器映射它，但由于一些奇怪的原因，上面的异常在我的运行时异常之前被抛出。有什么想法吗？

这是具有获取电话方法的类，但我的自定义例外：

import java.util.Base64;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;
import javax.persistence.Lob;
import javax.persistence.Transient;
import javax.ws.rs.ProcessingException;
import java.lang.StackTraceElement;

import com.server.messit.errorhandling.exceptions.DataNotFoundException;
import com.server.messit.errorhandling.exceptions.IncorrectValueException;
import com.server.messit.errorhandling.handler.ErrorChecker;

/**
 * @author Prasad
 *
 */
@Entity
@Inheritance(strategy=InheritanceType.JOINED)
public class User {
    @Id
    @Column(nullable = false, unique = true)
    private String phone;


    /**
     * @return the phone
     */
    public String getPhone() {
        return phone;
    }
    /**
     * @param phone the phone to set
     */
    public void setPhone(String phone) {
        if(!ErrorChecker.isValidPhoneNumber(phone)) {
            throw new DataNotFoundException("Incorrect Phone Number");
        } 
        this.phone = phone;
    }
}

这里是异常类：

public class DataNotFoundException extends RuntimeException {

    /**
     * 
     */
    private static final long serialVersionUID = -1422751876879336366L;

    public DataNotFoundException() {
        super();
    }

    public DataNotFoundException(String message) {
        super(message);
    }
}

这里是异常映射器类：

import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

import com.server.messit.errorhandling.handler.ErrorMessage;

/**
 * @author Prasad
 *
 */
@Provider
public class DataNotFoundExceptionMapper implements ExceptionMapper<DataNotFoundException>{

    @Override
    public Response toResponse(DataNotFoundException exception) {
        ErrorMessage errorMessage = new ErrorMessage(exception.getMessage(), 404, "Doc");
        return Response.status(Status.NOT_FOUND).entity(errorMessage).build();
    }

}

这里是抛出的异常：

javax.ws.rs.ProcessingException 异常在我的异常之前抛出，因此我无法将我的异常映射到自定义 json 响应。

Answer 1

我得到了答案。我不应该在我的数据模型类中抛出异常，即“用户”。 所以它给了我序列化错误。
