解决：Jersey搭建webService报错：com.sun.jersey.spi.inject.Er

1、在对应的POST GET方法中用了错误的参数

@Produces(MediaType.APPLICATION_JSON)
public String doPost( @FormParam("appid") String appid,@FormParam("sig") String sig,@FormParam("format") String format,@FormParam("data") String data){
    return gpsDataDoMain(appid,sig,format,data);
}
@GET
@Produces(MediaType.APPLICATION_JSON)
public String doGet(@QueryParam("appid") String appid,@QueryParam("sig") String sig,@QueryParam("format") String format,@FormParam("data") String data){    //<--错误
    return gpsDataDoMain(appid,data);

?2、在同一个包里有多个类@Path重复

@Path("/VendorList")
public class SerTest {
    private static String gpsDataDoMain(String appid,String sig,String format,String data){
        return "abc";
    }  
...

@Path("/VendorList") 
public class VendorList {
//static Logger logger = Logger.getLogger(VendorList.class);
private static String getVendorListDoMain(String appid,String keyWord,String erpSer){  
...
