java.lang.IllegalArgumentException:无效的uri'/赋值/rest/words/{name}/protection'；：转义绝对路径无效,java,spring,web-services,rest,Java,Spring,Web Services,Rest,我有SpringRESTfulWeb服务，它与postman（chrome中的插件）配合使用，URL（{name}/protection）需要一个名为“name”的参数我也用java编写了httpclient。使用以下代码 HttpClient client = new HttpClient(); PostMethod method = new PostMethod("http://localhost:8080/Assignment/rest/words/{name}/protection"

我有SpringRESTfulWeb服务，它与postman（chrome中的插件）配合使用，URL（{name}/protection）需要一个名为“name”的参数

我也用java编写了httpclient。使用以下代码

HttpClient client = new HttpClient();

PostMethod method = new PostMethod("http://localhost:8080/Assignment/rest/words/{name}/protection");
method.setParameter("name", "value");

    byte[] responseBody = null;
    int statusCode = 0;
    try {
        // Executing method.
        statusCode = client.executeMethod(method);
        }catch(Exception e){}
        // checking status code
        if (statusCode != HttpStatus.SC_OK) {
            System.err.println("Method failed: " + method.getStatusLine());
        }

        // Reading response body.
        responseBody = method.getResponseBody();

statusCode=client.executeMethod（方法）其错误显示如下

请帮助
最好先使用URLBuilder，然后将生成的URL分配给构造函数参数：
URIBuilder URIBuilder=new URIBuilder（）；
显然，在URI
中不允许使用大括号之类的字符。您必须对该部分进行编码
试着这样做：
PostMethod method = new PostMethod(URIUtil.encodePath("http://localhost:8080/Assignment/rest/words/{name}/protection", "UTF-8"));
method.setParameter("name", "value");

URIUtil
来自commons-httpclient-3.1

    <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <version>3.1</version>
    </dependency>


commons httpclient
commons httpclient
3.1
它显示java.net.URISyntaxException:索引44处路径中的非法字符：{name}/protection看起来像PostMethod.setParameter（）
和PostMethod.toString（）
未按预期工作。即，未设置参数。您能告诉我该类的完全限定名吗？我使用URIBuilder进行编码，它给出了400个错误请求，非常好
