Jersey 2.x 开发 restful 服务中，文件上传报错：

WARNING: No injection source found for a parameter of type public void com.xcar.rest.resources.xcar_pic.PictureResource.put(java.lang.String,java.lang.String,java.lang.String) throws java.io.IOException at index 1.

代码如下：

@Path("/v1/pictures/")
public class PictureResource {

    @POST @Path("/{param}")
    @Consumes(MediaType.MULTIPART_FORM_DATA) //MediaType.APPLICATION_OCTET_STREAM,MediaType.APPLICATION_FORM_URLENCODED,
    public void put(@PathParam("param") String pic_name,
                    @FormDataParam("key1") String value1,
                    @FormDataParam("key2") String value2) throws IOException {

        System.out.println(pic_name);
        System.out.println(value1);
        System.out.println(value2);
    }
}

客户端截图如下：

pom 文件依赖如下：

        </dependency>   

明明引用了 jersey-media-multipart 模块，为什么还是报错呢？

原来少了一个步骤，如下：

public class MyRestApplication extends ResourceConfig {
    public MyRestApplication() {

     //服务类所在的包路径  
     packages("com.xcar.rest.resources");
     //注册JSON转换器  
     register(JacksonJsonProvider.class);
     //注册文件上传模块
     register(MultiPartFeature.class);
    }  
}  

注意：一定要在这里进行注册才可以注入成功的！！！！

搞定！
