HTTP狀態500而不是HTTP狀態的JAX-RS響應400

有時JAR-RS客戶端發送錯誤的語法請求主體。服務器應迴應HTTP status 400 (Bad Request)，但它迴應HTTP status 500 (Internal Server Error)。HTTP狀態500而不是HTTP狀態的JAX-RS響應400

代碼：

JAX-B模型類：

@XmlRootElement(namespace = "http://www.test.com/test") 
@XmlAccessorType(value = XmlAccessType.FIELD) 
public class TestModel { 

    @XmlElement 
    private String id; 
}

JAX-RS資源類：

@Path("test") 
public class TestResource { 

    @POST 
    @Consumes(MediaType.APPLICATION_JSON) 
    public void create(TestModel testModel) { 
     // some code 
    } 
}

CXF配置：

<jaxrs:server address="/rest" id="test" staticSubresourceResolution="true"> 
    <jaxrs:serviceBeans> 
     <ref bean="testResource" /> 
    </jaxrs:serviceBeans> 
    <jaxrs:providers> 
     <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider" /> 
    </jaxrs:providers> 
</jaxrs:server>

例子：

請求正文：

{"id2": "test"}

的id2是錯誤的，所以客戶應該得到一個HTTP status 400，但它得到HTTP status 500。

是否有配置傑克遜和/或CXF返回HTTP狀態400錯誤的語法要求身體無schema validation或bean validation的方法嗎？

問題是未映射到響應的異常（通過ExceptionMapper s）轉換爲一般服務器錯誤響應，因爲運行時不知道如何處理異常。

jackson-jaxrs-provider模塊有ExceptionMapper s來處理Jackson基本異常類JsonMappingException和JsonParseException。映射器分別爲JsonMappingExceptionMapper和JsonParseExceptionMapper。這些映射器將異常映射到400響應以及作爲響應主體的異常消息。如果你不喜歡這個響應體，你可以編寫自己的映射器。
