RestTemplate请求Geoserver图层启动停止
通过设置图层基本资源信息中的启用可以设置图层是否可以被访问：
而关于它的详情与修改接口是：
代码如下：
String url ="http://IP:port/geoserver/rest/layers/BOU1_4M_L.xml";
String username ="admin";
String password ="geoserver";
/**
* 获取图层的详细信息
* @param url 访问地址
* @param username 用户名
* @param password 密码
* @return

Object result =new HashMap();
try {
HttpHeaders headers =new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setAccept(Arrays.asList(MediaType.APPLICATION_XML));
HttpEntity requestEntity =new HttpEntity(null, headers);
// 执行HTTP请求
RestTemplate restTemplate =new RestTemplate();
restTemplate.getInterceptors().add(new BasicAuthorizationInterceptor(username, password));
ResponseEntity response = restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class);
// 将xml字符串格式化
Document document = DocumentHelper.parseText(response.getBody());
// 获取根节点
Element rootElement = document.getRootElement();
// 获取resource节点
List resourceElements = rootElement.element("resource").elements();
// String href = rootElement.element("resource").element("link").attributeValue("href");
// 遍历resource节点获取atom:link节点href属性
for (int i =0; i < resourceElements.size(); i++) {
Element element = resourceElements.get(i);
if(element.getName() =="link"){
String href = element.attributeValue("href");
result =getLayerInfo(href,username,password);
break;
}
}
}catch (Exception e) {
e.printStackTrace();
}
return result;
}
