我使用Ubuntu并在其上安装了cURL。我想用cURL测试我的Spring
REST应用程序。我在Java端编写了POST代码。但是，我想用cURL对其进行测试。我正在尝试发布JSON数据。示例数据如下：

{"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true}

我使用以下命令：

curl -i \
    -H "Accept: application/json" \
    -H "X-HTTP-Method-Override: PUT" \
    -X POST -d "value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true \
    http://localhost:8080/xx/xxx/xxxx

它返回此错误：

HTTP/1.1 415 Unsupported Media Type
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=utf-8
Content-Length: 1051
Date: Wed, 24 Aug 2011 08:50:17 GMT

错误描述是这样的：

服务器拒绝了此请求，因为请求实体的格式不受请求方法（）的请求资源支持。

Tomcat日志：“ POST / ui / webapp / conf / clear HTTP / 1.1” 415 1051

cURL命令的正确格式是什么？

这是我的Java辅助PUT代码（我已经测试了GET和DELETE并且它们可以工作）：

@RequestMapping(method = RequestMethod.PUT)
public Configuration updateConfiguration(HttpServletResponse response, @RequestBody Configuration configuration) { //consider @Valid tag
    configuration.setName("PUT worked");
    //todo If error occurs response.sendError(HttpServletResponse.SC_NOT_FOUND);
    return configuration;
}
