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

我在http://docs.neo4j.org/chunked/milestone/server-java-rest-client-example.html上遵循了有关如何发送POST请求的指南.使用以下代码,我得到错误java.lang.NoSuchMethodError：javax.ws.rs.ext.MessageBodyWriter.isWriteable,这似乎与我使用的库有关.

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());
}

我不确定是否缺少依赖项或什么…

最佳答案

看来您的类路径中有不同的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,请仔细管理依赖项.

顺便说一句,如果您使用JFind(在目录/ JAR中找到一个类)和jd-gui(反编译JAR)之类的工具,则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
----------------
