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

Question

当json有效负载无效时，我试图返回自定义http响应(400错误请求(，而不是http 500服务器错误
问题是，当我在ExceptionMapper<T>中使用javax.json.bind.JsonbException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：

但我想知道是否有办法赶上javax.json.bind.JsonbException？

我使用的是Helidon MP 2.4.2。

再现：

1. 创建Helidon MP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.发送一个json日期无效的post请求。有效支付：

{
"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

我也遇到过类似的问题，我得到了这个解决方案，遵循了之前的解决方案(Jersey：当给出无效的请求体时，返回400错误，而不是500错误(。

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();
}
}

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 + "'}";
}
}

现在我正试图获取产生异常的详细字段，但我认为这已经是一个足够的解决方案了。
