異常：AbstractMethodError：javax.ws.rs.core.Response.getStatusInfo（）Ljavax/ws/rs/core/Response $ StatusType;

Question

當試圖用球衣1.18請求後，我得到以下異常：

Exception in thread "main" java.lang.AbstractMethodError: javax.ws.rs.core.Response.getStatusInfo()Ljavax/ws/rs/core/Response$StatusType; 
at javax.ws.rs.WebApplicationException.computeExceptionMessage(WebApplicationException.java:205)

at jtmt.shell.commands.Main.<init>(Main.java:42) 
at jtmt.shell.commands.Main.main(Main.java:64) 

的代碼產生是這樣的：

Trace trc = Trace.fromTracerouteResult(trace); 
    WebResource wr = _c.resource(URL); 
    WebResource.Builder wrb = wr.cookie(new Cookie("user", USER)); 
    wrb = wrb.cookie(new Cookie("auth", AUTH)); 
    wrb.post(trc); 
    return true; 

的entiry Trace看起來是這樣的：

@XmlRootElement 
public class Trace { 
    private Map<Integer,List<String>> addressesPerHop; 
    private String source; 
    private String traget; 

    /* getters and setters */ 
} 

我在編譯和執行時包含以下jar：

commons-cli-1.2.jar 
jersey-server-1.18.jar 
asm-3.1.jar 
jersey-servlet-1.18.jar 
jersey-client-1.18.jar 
jersey-core-1.18.jar 

任何想法whats missing？

簡答：您的Jersey版本太舊了。 javax.ws.rs.core.Response.getStatusInfo（）方法是2.0 JAX-RS規範的一部分。請參閱：https://jax-rs-spec.java.net/nonav/2.0-SNAPSHOT/apidocs/javax/ws/rs/core/Response.html#getStatusInfo()。

Jersey 2.0似乎是第一個支持JAX-RS 2.0的版本。
