想要实现Asp.net控制Tomcat启动关闭,我们需要用到Tomcat的管理Web界面,通过向Tomcat管理Web发送HTTP请求来实现Tomcat的启动和关闭。
- 配置Tomcat的管理Web界面
要实现Asp.net控制Tomcat启动关闭,需要在Tomcat的conf目录下的server.xml文件中添加以下配置:
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
rmiRegistryPortPlatform="8999" rmiServerPortPlatform="9000"
useLocalPorts="true"/>
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1"/>
<Realm className="org.apache.catalina.realm.MemoryRealm" />
<Role className="org.apache.catalina.users.MemoryRole" />
<User className="org.apache.catalina.users.MemoryUser" />
这些配置会为Tomcat创建一个管理Web界面,我们可以通过该界面来向Tomcat发送HTTP请求实现启动和关闭。
- 编写Asp.net代码
我们可以使用如下的Asp.net代码向Tomcat发送HTTP请求:
string url = "http://localhost:8080/manager/text";
var request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = new NetworkCredential("admin", "admin");
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";
string postData = "path=/myapp&command=start";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(byteArray, 0, byteArray.Length);
}
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var responseReader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
var responseText = responseReader.ReadToEnd();
}
}
这段代码可以向Tomcat的管理Web界面发送一个启动应用的请求:path指定应用的路径,command指定操作(start表示启动)。
当我们需要停止应用时,只需要将请求的command值改为stop即可。
- 示例说明
假设我们需要启动Tomcat服务器上的一个名为myapp的应用,在Asp.net中,我们可以使用如下代码启动该应用:
string url = "http://localhost:8080/manager/text";
var request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = new NetworkCredential("admin", "admin");
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";
string postData = "path=/myapp&command=start";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(byteArray, 0, byteArray.Length);
}
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var responseReader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
var responseText = responseReader.ReadToEnd();
}
}
当我们需要停止myapp应用时,可以使用如下代码:
string url = "http://localhost:8080/manager/text";
var request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = new NetworkCredential("admin", "admin");
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";
string postData = "path=/myapp&command=stop";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(byteArray, 0, byteArray.Length);
}
using (var response = (HttpWebResponse)request.GetResponse())
{
using (var responseReader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
var responseText = responseReader.ReadToEnd();
}
}
以上就是ASP.NET控制Tomcat启动关闭的实现方法的完整攻略,希望能对您有帮助。
