MULTIPART_FORM_DATA：找不到types为public javax.ws.rs.core.Response的参数的注入源

我正在使用基于泽西的宁静服务实施策略来build立一个服务，将用于上传文件。 我的服务类名称是：UploadFileService.java（请参阅下面的代码）

package com.jerser.service; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import javax.ws.rs.Consumes; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Response; import com.sun.jersey.core.header.FormDataContentDisposition; import com.sun.jersey.multipart.FormDataParam; @Path("/fileUpload") public class UploadFileService { @POST @Path("/upload") @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadFile( @FormDataParam("file") InputStream uploadedInputStream, @FormDataParam("file") FormDataContentDisposition fileDetail) { String uploadedFileLocation = "d://uploaded/" + fileDetail.getFileName(); // save it writeToFile(uploadedInputStream, uploadedFileLocation); String output = "File uploaded to : " + uploadedFileLocation; return Response.status(200).entity(output).build(); } // save uploaded file to new location private void writeToFile(InputStream uploadedInputStream, String uploadedFileLocation) { try { OutputStream out = new FileOutputStream(new File( uploadedFileLocation)); int read = 0; byte[] bytes = new byte[1024]; out = new FileOutputStream(new File(uploadedFileLocation)); while ((read = uploadedInputStream.read(bytes)) != -1) { out.write(bytes, 0, read); } out.flush(); out.close(); } catch (IOException e) { e.printStackTrace(); } } } 

这些是我在lib中的JAR文件：

 aopalliance-repackaged-2.4.0-b10.jar asm-debug-all-5.0.2.jar hk2-api-2.4.0-b10.jar hk2-locator-2.4.0-b10.jar hk2-utils-2.4.0-b10.jar javassist-3.18.1-GA.jar javax.annotation-api-1.2.jar javax.inject-2.4.0-b10.jar javax.servlet-api-3.0.1.jar javax.ws.rs-api-2.0.1.jar jaxb-api-2.2.7.jar jersey-client.jar jersey-common.jar jersey-container-servlet-core.jar jersey-container-servlet.jar jersey-core-1.11.jar jersey-guava-2.17.jar jersey-media-jaxb.jar jersey-multipart-1.18.jar jersey-server.jar org.osgi.core-4.2.0.jar osgi-resource-locator-1.0.1.jar persistence-api-1.0.jar validation-api-1.1.0.Final.jar 

当我试图启动我的tomcat服务器时出现以下错误：

 org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization. [[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response com.jerser.service.UploadFileService.uploadFile(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition) at index 0.; source='ResourceMethod{httpMethod=POST, consumedTypes=[multipart/form-data], producedTypes=[], suspended=false, suspendTimeout=0, suspendTimeoutUnit=MILLISECONDS, invocable=Invocable{handler=ClassBasedMethodHandler{handlerClass=class com.jerser.service.UploadFileService, handlerConstructors=[org.glassfish.jersey.server.model.HandlerConstructor@d3e2d4]}, definitionMethod=public javax.ws.rs.core.Response com.jerser.service.UploadFileService.uploadFile(java.io.InputStream,com.sun.jersey.core.header.FormDataContentDisposition), parameters=[Parameter [type=class java.io.InputStream, source=file, defaultValue=null], Parameter [type=class com.sun.jersey.core.header.FormDataContentDisposition, source=file, defaultValue=null]], responseType=class javax.ws.rs.core.Response}, nameBindings=[]}'] at org.glassfish.jersey.server.ApplicationHandler.initialize(ApplicationHandler.java:528) at org.glassfish.jersey.server.ApplicationHandler.access$500(ApplicationHandler.java:166) at org.glassfish.jersey.server.ApplicationHandler$3.run(ApplicationHandler.java:327) at org.glassfish.jersey.internal.Errors$2.call(Errors.java:289) at org.glassfish.jersey.internal.Errors$2.call(Errors.java:286) at org.glassfish.jersey.internal.Errors.process(Errors.java:315) at org.glassfish.jersey.internal.Errors.process(Errors.java:297) at org.glassfish.jersey.internal.Errors.processWithException(Errors.java:286) at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:324) at org.glassfish.jersey.servlet.WebComponent.<init>(WebComponent.java:338) at org.glassfish.jersey.servlet.ServletContainer.init(ServletContainer.java:171) at org.glassfish.jersey.servlet.ServletContainer.init(ServletContainer.java:363) at javax.servlet.GenericServlet.init(GenericServlet.java:160) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1176) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1102) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:1009) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4885) at org.apache.catalina.core.StandardContext$3.call(StandardContext.java:5212) at org.apache.catalina.core.StandardContext$3.call(StandardContext.java:5207) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) 

在互联网上，我发现有很多的例子说明如何使用RESTFul API上传MULTIPART文件。 但是同样的解决scheme。 我也无法运行这些代码。 我认为我在做JAR文件的错误。 任何人都可以帮助我吗？

Answer 1

摆脱jersey-multipart-1.18.jar 。 这是泽西岛1.x. 添加这两个

• 新泽西媒体多-2.17
• mimepull-1.9.3

对于Maven，你可以使用它

 <dependency> <groupId>org.glassfish.jersey.media</groupId> <artifactId>jersey-media-multipart</artifactId> <version>2.17</version> <!-- Make sure the Jersey matches the one you are currently using --> </dependency> 

然后你需要configuration/注册MultiPartFeature 。 如果您正在使用ResourceConfig进行configuration，则可以简单地执行

 register(MultiPartFeature.class); 

如果您使用的是web.xml，那么您可以将该类作为<init-param>到Jersey servlet中

 <init-param> <param-name>jersey.config.server.provider.classnames</param-name> <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value> </init-param> 

UPDATE

另外，一旦你摆脱了jersey-multipart-1.18.jar你将会为缺less的导入类编译错误。 大多数情况下，类名仍然是相同的，只是包已经改变，即

• org.glassfish.jersey.media.multipart.FormDataParam
• org.glassfish.jersey.media.multipart.FormDataContentDisposition

Answer 2

我也得到了同样的exception。我在web.xml中做了以下更改

 <init-param> <param-name>jersey.config.server.provider.classnames</param-name> <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.moxy.json.MoxyFeature;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value> </init-param> 

并把jersey2.7换成了2.9。我不知道这2的变化是怎么解决了这个问题的。
