Question

我正在使用Netbeans的 RESTful Web服务开发Web服务。服务类包含以下方法：

public String jpost(Object requestEntity) throws ClientErrorException {
        return webTarget.path("jpost").request(javax.ws.rs.core.MediaType.APPLICATION_JSON).post(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.APPLICATION_JSON), String.class);
    }

为了测试这种方法，我使用 Netbeans＆＃39; RESTful Java Client 生成测试方法。结果是：

jpost

当我呼叫Exception in thread "main" javax.ws.rs.NotAcceptableException: HTTP 406 Not Acceptable at org.glassfish.jersey.client.JerseyInvocation.convertToException(JerseyInvocation.java:923) at org.glassfish.jersey.client.JerseyInvocation.translate(JerseyInvocation.java:770) at org.glassfish.jersey.client.JerseyInvocation.access$500(JerseyInvocation.java:90) at org.glassfish.jersey.client.JerseyInvocation$2.call(JerseyInvocation.java:671) at org.glassfish.jersey.internal.Errors.process(Errors.java:315) at org.glassfish.jersey.internal.Errors.process(Errors.java:297) at org.glassfish.jersey.internal.Errors.process(Errors.java:228) at org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:422) at org.glassfish.jersey.client.JerseyInvocation.invoke(JerseyInvocation.java:667) at org.glassfish.jersey.client.JerseyInvocation$Builder.method(JerseyInvocation.java:423) at org.glassfish.jersey.client.JerseyInvocation$Builder.post(JerseyInvocation.java:326) at myserver.test5.jpost(test5.java:36) at myserver.MyServerTest.main(MyServerTest.java:32)时出现以下错误：

有什么问题？

您的服务仅生成text/plain个回复。

HTTP代码406表示服务器无法提供客户端可接受的内容类型。因此，客户端在Accepts标头中指定了错误的内容类型，或者根本没有发送Accepts。

要指定接受的类型，请使用request(...)参数。

public String jpost(Object requestEntity) throws ClientErrorException 
{
    return webTarget.path("jpost")
            .request(javax.ws.rs.core.MediaType.TEXT_PLAIN)
            .post(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.APPLICATION_JSON), String.class);
}

Netbeans的＆＃39; RESTful Java客户端：javax.ws.rs.NotAcceptableException：HTTP 406不可接受
