CXF - 沒有發現郵件正文閱讀器的類附件

我試圖用幾天時間在我的Web服務REST上使用Apache CXF和TomEE v7上的文件。儘管谷歌和測試解決方案一次又一次沒有爲我工作。CXF - 沒有發現郵件正文閱讀器的類附件

還有就是我的Maven依賴

<dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-core</artifactId> 
    <version>3.1.11</version> 
</dependency> 
<dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-bundle</artifactId> 
    <version>3.0.0-milestone2</version> 
</dependency> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
    <version>3.1.0</version> 
</dependency> 
<dependency> 
    <groupId>javax.ws.rs</groupId> 
    <artifactId>javax.ws.rs-api</artifactId> 
    <version>2.0.1</version> 
</dependency>

Java的端點

@POST 
@Consumes(MediaType.MULTIPART_FORM_DATA) 
public Response uploadImage(@Multipart(value = "file") Attachment attr) throws IOException { 

    { ... } 

    return Response.status(Response.Status.CREATED).entity("File succesfully uploaded").build(); 
}

HTML客戶

<form action="http://localhost:8080/.../api/images" method="post" enctype="multipart/form-data"> 

    <p> 
    Select a file : <input type="file" name="file" size="50" /> 
    </p> 

    <input type="submit" value="Upload It" /> 
</form>

但我總是得到這個錯誤

我在做什麼錯？您的幫助將不勝感激。

如果您有二進制（非字母數字）數據（或大小有效載荷）進行傳輸，請使用multipart/form-data。否則，請使用application/x-www-form-urlencoded，因爲它顯示「WARNING - javax.ws.rs.WebApplicationException：HTTP 415 Unsupported Media Type」。

首先，我不確定您的CXF REST服務是否啓動並運行給定的pom.xml。如果不是，則需要添加以下附加依賴項。

 <dependency> 
      <groupId>org.apache.cxf</groupId> 
      <artifactId>cxf-rt-transports-http</artifactId> 
      <version>3.1.11</version> 
     </dependency> 
     <!-- https://mvnrepository.com/artifact/org.apache.cxf/cxf-rt-frontend-jaxrs --> 
     <dependency> 
      <groupId>org.apache.cxf</groupId> 
      <artifactId>cxf-rt-frontend-jaxrs</artifactId> 
      <version>3.1.11</version> 
     </dependency>

最後請確保您的附件類是包org.apache.cxf.jaxrs.ext.multipart或org.apache.cxf.message
