如何在javax.json.bind.JsonbException (Helidon )上返回自定义响应

Question

当json有效负载无效时，我试图返回一个自定义http响应(400个错误请求)，而不是http 500服务器错误。

问题是，当我在javax.json.bind.JsonbException中使用ExceptionMapper<T>作为异常类型时，它无法捕获它，但我可以捕获更通用的javax.ws.rs.ProcessingException。

很明显，javax.ws.rs.ProcessingException是由javax.json.bind.JsonbException引起的，因为堆栈跟踪显示：

但我想知道有没有办法抓住javax.json.bind.JsonbException

我使用的是Helidon 2.4.2。

复制：

1. 创建Helidon 链接的快速启动
2. 在问候语资源上添加post方法

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    public void add(MyClass cal){
        System.out.println(cal.getDate());
    }

public class MyClass {
    private String name;
    private Date date;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public MyClass(String name, Date date) {
        this.name = name;
        this.date = date;
    }

    public MyClass() {
    }
    
}

3.发送带有无效json日期的post请求。有效工资：

{
    "name": "testg",
    "date": "2022-03-31T10:37:23.005Z[UTC]"
}

无效(日期)有效载荷：

{
    "name": "testg",
    "date": "2022-03-31T10:37:23.005Z[UTC]XXXXXXXX"
}

Answer 1

我也遇到过类似的麻烦，而且这个解决方案是按照以前的解决方案(泽西:当给出无效的请求体时，返回400错误而不是500)来实现的。

import java.time.format.DateTimeParseException;
import javax.json.bind.JsonbException;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
import org.apache.johnzon.mapper.MapperException;
import static javax.ws.rs.core.MediaType.APPLICATION_JSON_TYPE;
@Provider
public class InvalidDataMapper implements ExceptionMapper<JsonbException>         {
@Override
public Response toResponse(JsonbException arg0) {
    if (arg0.getCause() instanceof MapperException) {
        MapperException exception = (MapperException) arg0.getCause();
        ErrorMessage errorMessage = null;
        if (exception.getCause() instanceof DateTimeParseException) {
            errorMessage = new ErrorMessage(CustomCodesAndMessages.CODE_ERROR_FORMAT_DATE, exception.getMessage());
        }
        if (exception.getCause() instanceof NumberFormatException) {
            errorMessage = new ErrorMessage(CustomCodesAndMessages.CODE_ERROR_FORMATO_NUMERIC, exception.getMessage());
        }
        return Response.status(Response.Status.BAD_REQUEST).type(APPLICATION_JSON_TYPE).entity(errorMessage).build();
    }
    return Response.status(Response.Status.BAD_REQUEST).build();
  }
}

而ErrorMessage是

package fif.tech.utiles;
import java.util.Objects;
import org.apache.cxf.jaxrs.ext.Nullable;
import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class ErrorMessage {
private final int code;
private final String message;
private final String details;
public ErrorMessage(String message) {
    this(500, message);
}
public ErrorMessage(int code, String message) {
    this(code, message, null);
}
@JsonCreator
public ErrorMessage(@JsonProperty("code") int code,     @JsonProperty("message") String message,
                    @Nullable @JsonProperty("details") String details) {
    this.code = code;
    this.message = message;
    this.details = details;
}
@JsonProperty("code")
public Integer getCode() {
    return code;
}

@JsonProperty("message")
public String getMessage() {
    return message;
}

@JsonProperty("details")
@Nullable
public String getDetails() {
    return details;
}

@Override
public boolean equals(final Object obj) {
    if (this == obj) {
        return true;
    }
    if ((obj == null) || (getClass() != obj.getClass())) {
        return false;
    }

    final ErrorMessage other = (ErrorMessage) obj;
    return Objects.equals(code, other.code)
            && Objects.equals(message, other.message)
            && Objects.equals(details, other.details);
}

@Override
public int hashCode() {
    return Objects.hash(code, message, details);
}

@Override
public String toString() {
    return "ErrorMessage{code=" + code + ", message='" + message + "', details='" + details + "'}";
 }
}

现在我试图捕捉产生异常的详细字段，但我认为这是一个足够的解决方案。
