java.lang.NoSuchMethodError: javax.ws.rs.ext.MessageBodyWriter.isWriteable
提问by Webnet
I followed the guide here http://docs.neo4j.org/chunked/milestone/server-java-rest-client-example.htmlon how to send a POST request. Using the below code I get the error java.lang.NoSuchMethodError: javax.ws.rs.ext.MessageBodyWriter.isWriteablewhich appears to be an issue with the library I'm using.
我按照这里的指南http://docs.neo4j.org/chunked/milestone/server-java-rest-client-example.html关于如何发送 POST 请求。使用下面的代码我得到错误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());
}
I am unsure if I'm missing a dependency or what...
我不确定我是否缺少依赖项或什么......

It seems that you have different javax.ws.rs.ext.MessageBodyWriter classes in your classpath. One is from jsr311-api-0.8.jar and the other one is from jersey-core-1.17.jar. So please manage the dependencies carefully.
您的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。所以请仔细管理依赖项。
By the way, if you use tools, like JFind(find a class in a directory/JAR) and jd-gui(decompile a JAR), you can resolve this kind of issues easily.
顺便说一句，如果您使用JFind（在目录/JAR 中查找类）和jd-gui（反编译JAR）之类的工具，则可以轻松解决此类问题。
The following is my JFind output:
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.17\jersey-core-1.17.jar
----------------
ClassName = javax/ws/rs/ext/MessageBodyWriter.class
JarName = C:\Users\lhuang\.m2\repository\javax\ws\rs\jsr311-api##代码##.8\jsr311-api-0.8.jar
----------------
