java Web 启动时自动执行代码的几种方式
Web容器启动后执行代码的几种方式
其执行顺序为：
4===5===1===2===3
即指定init-method的Bean开始执行
接着实现spring的Bean后置处理器开始执行
然后是Servlet的监听器执行
再接下来是Servlet的过滤器执行
最后才是Servlet执行
1、实现Servlet监听器接口ServletContextListener
[java] view plain copy
public class InitListener implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent context) {
}
@Override
public void contextInitialized(ServletContextEvent context) {
// 上下文初始化执行
System.out.println("================[ServletContextListener]自动加载启动开始.");
SpringUtil.getInstance().setContext(
span style="white-space:pre" /spanWebApplicationContextUtils.getWebApplicationContext(arg0.getServletContext())
span style="white-space:pre" /span);
}
}
然后在web.xml文件配置该监听器
[html] view plain copy
listener
listener-classcom.test.init.InitListener/listener-class
/listener
2、实现Servlet的过滤器Filter
[html] view plain copy
public class InitFilter implements Filter {
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException,
ServletException {
}
@Override
public void init(FilterConfig config) throws ServletException {
System.out.println("================[Filter]自动加载启动开始.");
// 读取Spring容器中的Bean[此时Bean已加载,可以使用]
//写启动需要执行的代码
System.out.println("================[Filter]自动加载启动结束.");
}
}
然后在web.xml文件配置过滤器即可
[html] view plain copy
filter
filter-nameInitFilter/filter-name
filter-classcom.test.init.InitFilter/filter-class
/filter
filter-mapping
filter-nameInitFilter/filter-name
url-pattern//url-pattern
/filter-mapping
3、编写一个Servlet,在web.xml里面配置容器启动后执行即可
[html] view plain copy
public class InitServlet extends HttpServlet {
/**
*/
private static final long serialVersionUID = 1L;
@Override
public void init(ServletConfig config) {
try {
super.init();
} catch (ServletException e) {
e.printStackTrace();
}
System.out.println("================[Servlet]自动加载启动开始.");
// 读取Spring容器中的Bean[此时Bean已加载,可以使用]
//执行想要的代码
System.out.println("================[Servlet]自动加载启动结束.");
}
}
然后在web.xml文件配置该Servlet的启动方式为：容器启动后执行
servlet
servlet-nameInitServlet/servlet-name
servlet-classcom.test.init.InitServlet/servlet-class
init-param
param-nameusername/param-name
param-valuetest/param-value
/init-param
!-- 此处指定加载顺序为2,表明还有优先级更高的Servlet要先执行 --
load-on-startup2/load-on-startup
/servlet
servlet-mapping
servlet-nameInitServlet/servlet-name
url-pattern//url-pattern
/servlet-mapping
关于启动后执行，由load-on-startup指定：
（1）当值为0或者大于0时，表示容器在应用启动时就加载这个servlet。值越小，启动优先级越高；
（2）当是一个负数时或者没有指定时，表示该servlet被调用时才加载。
4、如果你使用Spring IOC作为Bean管理容器，那么可以指定init-method其中init-method表示bean加载成功后，立即执行某个方法。配置如下：start为要执行的方法名称
[html] view plain copy
!-- service --
bean id="shopService" class="com.test.teach.service.ShopService" span style="color:#33ffff;"init-method="start"/span
property name="shopDao" ref="shopDao" /
/bean
AnimationDrawable.start()应该在哪里调用啊？
[mw_shl_code=java,true]final ImageView tweenImage = (ImageView) findViewById(R.id.imageView1);tweenImage.setBackgroundResource(R.anim.cubicfacetween); tweenImage.post(new Runnable() { @Override public void run() { AnimationDrawable frameAnimation = (AnimationDrawable) tweenImage.getBackground(); frameAnimation.start(); }}[/mw_shl_code]完美运行，但如果是定制ProgressDialog，然后把动画放到这个自定义的布局里的话，还是没用
怎么用java做动画
重写paint方法，来实现将自己定义的图片绘制到组件中，然后启动一个线程来控制paint方法。 示例： ××××××××××××××××××××××××××× import javax.swing.*; import java.awt.*;class MyPanel extends JPanel implements Runnable {private Image img;private int i=0;private int j=0;public MyPanel(){img=new ImageIcon("1.png").getImage();}public void paint(Graphics g){g.drawImage(img,0,0,60,104,i*60,j*104,i*60+60,j*104+104,this);}public void run(){while(true){while(j {while(i {try{Thread.sleep(300);}catch(Exception e){}this.repaint();i++;}j++;i=0;}i=0;j=0;}} }public class test extends JFrame {private MyPanel p;public test(){p=new MyPanel();this.add(p,BorderLayout.CENTER);this.setBounds(300,200,300,300);this.setTitle("人物行走图");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 将以上源码保存为：test.java，编译，然后下载下面的图片 将下载的图片改名为1.png" target="_blank"
,然后将其和编译后生成的class文件放在同一文件夹下，然后运行就可以了·～～
如何创建启动界面Splash Screen
启动界面Splash Screen在应用程序是很常用的，往往在启动界面中显示产品Logo、公司Logo或者开发者信息，如果应用程序启动时间比较长，那么启动界面就是一个很好的东西，可以让用户耐心等待这段枯燥的时间。
Android 应用程序创建一个启动界面Splash Screen非常简单。比如创建一个工程MySample，主Acitity就叫MySample，创建另一个Activity叫 SplashScreen，用于显示启动界面，资源文件为splash.xml。至于如何制作SplashSceen界面，这不是本文章要讨论的东西，就此略过。
SplashScreen的代码如下：
package com.ctoof.android;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
public class SplashScreen extends Activity {
protected boolean _active = true;
protected int _splashTime = 5000;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread splashTread = new Thread() {
@Override
public void run() {
try {
int waited = 0;
while(_active (waited _splashTime)) {
sleep(100);
if(_active) {
waited += 100;
}
}
} catch(InterruptedException e) {
// do nothing
} finally {
finish();
// 启动主应用
startActivity(new Intent("com.ctoof.android.MySample.MyApp"));
stop();
}
}
};
splashTread.start();
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
_active = false;
}
return true;
}
}
然后在AndroidMainfest.xml中修改代码如下：
?xml version="1.0" encoding="utf-8"?
manifest xmlns:android=""
package="com.ctoof.android"
android:versionCode="1"
android:versionName="1.0"
application android:icon="@drawable/icon" android:label="@string/app_name"
activity android:name=".SplashScreen"
android:label="@string/app_name"
intent-filter
action android:name="android.intent.action.MAIN" /
category android:name="android.intent.category.LAUNCHER" /
/intent-filter
/activity
activity android:name=".MyApp"
intent-filter
action android:name=" com.ctoof.android. MySample.MyApp " /
category android:name="android.intent.category.DEFAULT" /
/intent-filter
/activity
/application
uses-sdk android:minSdkVersion="4" /
/manifest
在这里负责注册两个活动。把负责管理启动界面Splash Screen的活动Activity作为应用程序的主活动，然后在SplashScreen中负责启动MyApp。
另：
很多应用都会有一个启动界面。欢迎画面慢慢隐现，然后慢慢消隐。实现这种效果的方法有两种（暂时只发现两种）
1、使用两个Activity，程序启动时候load第一张Activity，然后由tick触发N秒钟后startActivity另外一张Activity。
2、使用一个Activity，可以用到View.gone() 这个方法。把Acitivity的某些元素移除。
Java代码
public class Splash extends Activity {
private final int SPLASH_DISPLAY_LENGHT = 3000; //延迟三秒
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
Intent mainIntent = new Intent(Splash.this,Main.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGHT);
}
}
当然可以再Splash中加入动画效果。
