java - 如何将 Restful 服务上的字符串转换为 xml 文件以进行 xsd 验证

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

更新后的客户端代码是

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");

        ////


        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();

更新后的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 xml 文件，以便使用 xsd 进行验证..任何人都可以有将字符串转换为 XML 文件的想法

////这是我之前从 GAgarwarl 的帖子中得到答案的问题///我正在更新问题，现在我能够将 xml 文件发送到 Restful 服务，如何阅读此内容在 Restful 服务上读取此 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");

我的安静代码是

@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

    }

}

////这是老问题////

我对 Web 服务完全陌生，我必须在系统位置发送一个 XML 文件，如 c:/Files/Samle.xml从java客户端到Restful Web服务，之前我已经将json对象发送到Restful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());

我的安静代码是

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

        {
}

以同样的方式，我想将 xml 文件发送到 Restful 服务，有人可以有任何想法吗？

Answer 1

替换 String json = "{\"EMPCODE\":\"125\",\"NAME_TBH\":\"aaaaa\"}";与:

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();
