RESTful生成二进制文件 [英] RESTful produces binary file
问题描述
我是使用CXF和Spring创建RESTful Web服务的新手。
I'm new using CXF and Spring to make RESTful webservices.
这是我的问题:我想创建一个生成任何类型文件的服务(可以是图像,文档,txt甚至pdf),也可以是XML。到目前为止,我得到了这个代码:
This is my problem: I want to create a service that produces "any" kind of file(can be image,document,txt or even pdf), and also a XML. So far I got this code:
@Path("/download/")
@GET
@Produces({"application/*"})
public CustomXML getFile() throws Exception;
我不确切知道从哪里开始所以请耐心等待。
I don't know exactly where to begin so please be patient.

@Path("/download/")
@GET
public javax.ws.rs.core.Response getFile() throws Exception {
if (/* want the pdf file */) {
File file = new File("...");
return Response.ok(file, MediaType.APPLICATION_OCTET_STREAM)
.header("content-disposition", "attachment; filename =" + file.getName())
.build();
}
/* default to xml file */
return Response.ok(new FileInputStream("custom.xml")).type("application/xml").build();
}
推荐答案
如果它将返回任何文件,您可能希望使您的方法更通用并返回一个javax.ws.rs.core.Response,您可以通过编程方式设置Content-Type标头:
If it will return any file, you might want to make your method more "generic" and return a javax.ws.rs.core.Response which you can set the Content-Type header programmatically:
@Path("/download/")
@GET
public javax.ws.rs.core.Response getFile() throws Exception {
if (/* want the pdf file */) {
return Response.ok(new File(/*...*/)).type("application/pdf").build();
}
/* default to xml file */
return Response.ok(new FileInputStream("custom.xml")).type("application/xml").build();
}
