小编use*_*894的帖子

在做了一些研究之后我问了这个问题.我确实遵循了这种错误给出的解决方案,但对我没有用.在下面的代码中出现错误的任何建议.我正在创建一个REST API但是当我请求url时它给了我405错误.Below是请求的URI.

    http://localhost:8080/Project/services/start/version

以下是代码段.

@Path("/start")

public class StartService {
@GET
@Path("/version")
@Produces({"text/plain","application/xml","application/json"})
public String getVersion() {
    String ver="";

    try{


          Runtime rt = Runtime.getRuntime();
          Process pr = rt.exec("C:\\server\\dgr -v" );

          BufferedReader stdInput = new BufferedReader(new InputStreamReader
(pr.getInputStream()));
          BufferedReader input = new BufferedReader(stdInput);
         // String ver ="";
          StringBuffer verOutput = new StringBuffer();
                while((ver =  input.readLine()) != null){
                    verOutput.append(ver + "\n");
                    System.out.println(ver);
                }


        }catch (Throwable t)  
          {  
            t.printStackTrace();  
          }  


        finally {  

        }
    return ver;  }

}

web.xml中:

我在做了大量的研究之后问了这个问题,并且在研究之后在我的代码中实现了这个问题,但我最终得到了FileNotFoundException.我在这里做的是我想要避免在我的java代码中使用硬编码所以创建一个名为的属性文件作为Constants.properties并在我的java代码中调用它.但它说它找不到文件.我的属性文件位于项目的src文件夹中.以下是代码段.有什么建议？

属性文件:

executable.run = C:\\server\\lrd.exe
incoming.file = C:\\file\\test.ic
executable.params1 = -z
executable.params2 = -a[+]
log.file = C:\\TESTFile\\test.txt

Java代码:这是具有属性文件详细信息的类文件.

public class PropInfo {
    static private PropInfo _instance =  null;
    public String executable =  null;
    public String filein = null;
    public String params1 = null; 
    public String params2 = null; 
    public String log = null; 

    protected PropInfo(){
        try{
            InputStream file = new FileInputStream(new File("Constants.properties"));
            Properties props = new Properties();
            props.load(file);
            executable = props.getProperty("executable.run");
            filein = props.getProperty("incomin.file");
            params1 = props.getProperty("executable.params1");
            params2 = props.getProperty("executable.params2"); …
