如何将restful服务上的String转换为用于xsd验证的xml文件

Question

更新的问题

我已经将我的客户端代码和restful服务代码修改为

更新的cliet代码是

URL url = new URL("http://localhost:9090/XsdValidation/api/data/xml");
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/xml");
        ////

        StringBuilder builder = new StringBuilder();
        FileReader fileReader = new FileReader("Employee.xml");
        BufferedReader reader = new BufferedReader(fileReader);
        for (String line = reader.readLine(); line != null; line = reader.readLine()) {
            builder .append(line);
        }
        String xml = builder .toString();
        System.out.println("xml file is "+xml);
        OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
        out.write(xml);
        out.close();
        reader.close();

更新的rest ful服务代码是

@Path("/data")
public class DataAccess {
    @POST
    @Path("/xml")
    @Consumes(MediaType.APPLICATION_XML)
    public String readXml(String file) {
        System.out.println("in xml");
        return file;
    }
}

一切都很好，我得到的字符串是<?xml version="1.0" encoding="UTF-8"?><empns:employee xmlns:empns="Symplocus/Employee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="Symplocus/Employee Employee.xsd "> <empns:EMP_ID>0101</empns:EMP_ID> <empns:NAME>Rajasekhar</empns:NAME> <empns:SALARY>2000</empns:SALARY> <empns:DATEOFJOINING>2001-01-01</empns:DATEOFJOINING></empns:employee>

我想将整个字符串转换为一个xml文件，以便使用xsd进行验证。。有人能想到把字符串转换成XML文件吗

////这是之前的问题，我从加瓦尔的帖子中得到了答案///我正在更新这个问题，现在我可以将xml文件发送到restful服务，如何在restful服务上读取这个xml

我的客户端代码是

URL url = new URL("http://localhost:9090/XsdValidation/api/data/xml");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type", "application/xml");
    OutputStream os = connection.getOutputStream();
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    FileReader fileReader = new FileReader("Employee.xml");
    StreamSource source = new StreamSource(fileReader);
    StreamResult result = new StreamResult(os);
    transformer.transform(source, result);
    os.flush();
    System.out.println(connection.getResponseCode());
    //connection.disconnect();
     BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
     System.out.println("in input stream");
     String decodedString;
     while ((decodedString = in.readLine()) != null) {
     System.out.println(decodedString);
     }
     in.close(); 
     System.out.println(connection.getResponseCode());
    System.out.println("end of client programme");

我的宁静代码是

@Path("/data")
public class DataAccess {
    @POST
    @Path("/xml")
    @Consumes(MediaType.APPLICATION_XML)
    public String readXml(/here i have to read file /) {
             // here i want an idea to read the file sent by client
    }
}

////这是个老问题////

我对web服务完全陌生，我必须从java客户端向Restful web服务发送系统位置（如c:/Files/Samle.xml）中的XML文件，以前我曾向Restful发送json对象，但无法发送XML

我发送json的客户端代码是

String tableName="SYMPLOCUS.IMDB1_FINANCE_BUDGE ";
        String urlString="http://localhost:9090/DataAccess/api/DataAccess/loadData?tableName="+tableName;
        URL url=new URL(urlString);
        HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
        httpCon.setDoOutput(true);
        httpCon.setRequestMethod("POST");
        httpCon.setRequestProperty("Content-Type", 
                "application/json");
        OutputStreamWriter out = new OutputStreamWriter(httpCon.getOutputStream());
        String json = "{"EMPCODE":"125", "NAME_TBH":"aaaaa"}";
        out.write(json);
        out.close();
        BufferedReader in = new BufferedReader(new InputStreamReader(httpCon.getInputStream()));
        System.out.println("in input stream");
        String decodedString;
        while ((decodedString = in.readLine()) != null) {
        System.out.println(decodedString);
        }
        in.close(); 
        System.out.println(httpCon.getResponseCode());

我的宁静代码是

@Path("/loadData")
        @POST
        @Produces(MediaType.APPLICATION_JSON)
        @Consumes(MediaType.APPLICATION_JSON)
        public String sendReceiveJson(String data,@QueryParam("tableName") String tableName) 
        {
}

就像我想把xml文件发送到restful服务一样，有人能有什么想法吗。。

Answer 1

替换字符串json="｛\"EMPCODE\"：\"125\"，\"NAME_TBH\"："aaaa\"｝"；带有：

StringBuilder builder = new StringBuilder();
FileReader fileReader = new FileReader("fileName");
BufferedReader reader = new BufferedReader(fileReader);
for (String line = reader.readLine(); line != null; line = reader.readLine()) {
    builder .append(line);
}
String xml = builder .toString();

Answer 2

更改：

@consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})

也在您的客户端设置中：

httpCon.setRequestProperty("content-type","application/xml")

然后发送您的XML数据。
