用HTTPClient自动登录Tomca管理页面
前提是你在你的tomcat-users.xml下配置好admin用户：

- to operate the “/manager/html” web application. If you wish to use this app,
- you must define such a user – the username and password are arbitrary.

- <role rolename=”tomcat”/>
- <role rolename=”role1″/>
- <role rolename=”manager”/>
- <role rolename=”admin”/>
- <user username=”tomcat” password=”tomcat” roles=”tomcat”/>
- <user username=”both” password=”tomcat” roles=”tomcat,role1″/>
- <user username=”role1″ password=”tomcat” roles=”role1″/>
- <user username=”admin” password=”admin” roles=”admin,manager”/>
- </tomcat-users>
自动登录代码如下：
[java][/java] view plaincopyprint?
- <pre name=”code” class=”java”>import java.io.IOException;
- import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;
- import org.apache.commons.httpclient.HttpClient;
- import org.apache.commons.httpclient.HttpException;
- import org.apache.commons.httpclient.HttpStatus;
- import org.apache.commons.httpclient.UsernamePasswordCredentials;
- import org.apache.commons.httpclient.auth.AuthScope;
- import org.apache.commons.httpclient.methods.GetMethod;
- import org.apache.commons.httpclient.params.HttpMethodParams;
- public class AutoLoginTomcat {
- /**
- * @param args
- */
- public static void main(String[] args) {
- HttpClient httpClient = new HttpClient();
- httpClient.getState().setCredentials(
- new AuthScope(“127.0.0.1”, 8080, null),
- new UsernamePasswordCredentials(“admin”, “admin”));
- httpClient.getParams().setAuthenticationPreemptive(true);
- GetMethod getMethod = new GetMethod(
- “http://127.0.0.1:8080/manager/status?XML=true”);
- getMethod.setDoAuthentication(true);
- getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
- new DefaultHttpMethodRetryHandler());
- try {
- int statusCode = httpClient.executeMethod(getMethod);
- if (statusCode != HttpStatus.SC_OK) {
- System.err.println(“Method failed: “
- + getMethod.getStatusLine());
- }
- byte[] responseBody = getMethod.getResponseBody();
- System.out.println(new String(responseBody));
- } catch (HttpException e) {
- System.out.println(“Please check your provided http address!”);
- e.printStackTrace();
- } catch (IOException e) {
- e.printStackTrace();
- } finally {
- getMethod.releaseConnection();
- }
- }
- }
