Question

当我发送一个对象而不是一个数组时，我得到一个ProcessingException。即使使用javax.ws.rs.ext.ExceptionMapper＆lt;我也无法捕获ProcessingException。例外＆gt;

我正在使用球衣2.25

@POST
@Path("/post")
@Consumes(MediaType.APPLICATION_JSON)
public Response testInJSON(Test[] test) {

    String result = "Test message : " + test[0].getTest();  
    return Response.status(Response.Status.ACCEPTED).entity(result).build();

}

的pom.xml

public class Test implements Serializable{
    private static final long serialVersionUID = 1L;
    private String test;
    public String getTest() {
        return test;
    }
    public void setTest(String test) {
        this.test = test;
    }
}

更新：这似乎是一个框架错误。吉拉已经开业了。 https://java.net/jira/browse/JERSEY-3222

ProcessingException处理由ResponseErrorMapper覆盖，而不是ExceptionMapper：

public class MyExceptionMapper implements ExceptionMapper<Throwable>, ResponseErrorMapper {
    ...

要使其正常运行，您需要在应用程序配置中设置“ PROCESSING_RESPONSE_ERRORS_ENABLED”属性：

val config = ResourceConfig()
config.register(new MyExceptionMapper(...))
config.setProperties(new LinkedHashMap<String, Object>() {{
    put(org.glassfish.jersey.server.ServerProperties.PROCESSING_RESPONSE_ERRORS_ENABLED, true);
}});

发送对象而不是数组时，我无法捕获ProcessingException
