java.lang.NoSuchMethodError:javax.ws.rs.ext.MessageBodyWriter.isWriteable

我按照这里的指南来发送POST请求。使用下面的代码，我得到了错误

java.lang.NoSuchMethodError:javax.ws.rs.ext.MessageBodyWriter.isWriteable

，这似乎是我正在使用的库的问题

public Object getResponse(Object responseClass) {
    Client client = Client.create();

    WebResource webResource = client.resource(getUrl());
    ClientResponse response = webResource
            .type(MediaType.APPLICATION_JSON)
            .entity(responseClass)
            .post(ClientResponse.class);

    if (response.getStatus() != 201)
        return null;

    return response.getEntity(responseClass.getClass());
}

我不确定我是否缺少依赖关系或什么

我的pom.xml包括

类路径中似乎有不同的javax.ws.rs.ext.MessageBodyWriter类。一个来自jsr311-api-0.8.jar，另一个来自jersey-core-1.17.jar。因此，请仔细管理依赖关系

顺便说一下，如果您使用诸如（在目录/JAR中查找类）和（反编译JAR）之类的工具，您可以轻松解决此类问题

以下是我的JFind输出：

ClassName = javax/ws/rs/ext/MessageBodyWriter.class
JarName = C:\Users\lhuang\.m2\repository\com\sun\jersey\jersey-core\1.17\jersey-core-1.17.jar
----------------
ClassName = javax/ws/rs/ext/MessageBodyWriter.class
JarName = C:\Users\lhuang\.m2\repository\javax\ws\rs\jsr311-api\0.8\jsr311-api-0.8.jar
----------------

@MinhKieu也许你可以重命名一个人的包以避免冲突。jarjar是一个用于此的工具。
