java - com.owlike.genson.JsonBindingException : Could not deserialize to type class javax. ws.rs.core.Response

Question

我有 Jersey 1.19 REST Web 服务，它返回自定义 @XmlRootElement 响应对象并且运行良好。但是，当我稍后执行应该断言 javax.ws.rs.core.Response 的测试时，我收到异常:

javax.ws.rs.WebApplicationException: com.owlike.genson.JsonBindingException: Could not deserialize to type class javax.ws.rs.core.Response
    at com.owlike.genson.ext.jaxrs.GensonJsonConverter.readFrom(GensonJsonConverter.java:127)
    at com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:634)

响应类型:

@XmlRootElement
public class MyResponse {
    public String message;
}

返回 MyResponse 的端点:

@GET
@Path("/info")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public MyResponse getInfo(){
    return new MyResponse();
}

我的 pom.xml 片段包含相关库:

    <scope>compile</scope>

</dependency>

如何解决这个问题？

Answer 1

这是客户端的问题。将预期类型从 Response 更改为 com.sun.jersey.api.client.ClientResponse:

protected ClientResponse executeGet(String path){
    WebResource resource = resource().path(path);
    Builder builder = resource.header("Content-Type", "application/json;charset=UTF-8");
    return builder.get(ClientResponse.class);
}
