Java獲得此次要求URL和辦事器根途徑的辦法

編輯：關於JAVA

Java獲得此次要求URL和辦事器根途徑的辦法。本站提示廣大學習愛好者：（Java獲得此次要求URL和辦事器根途徑的辦法）文章只能為提供參考，不一定能成為您想要的結果。以下是Java獲得此次要求URL和辦事器根途徑的辦法正文

本文引見了Java獲得此次要求URL和獲得辦事器根途徑的辦法，而且停止舉例解釋，感興致的同伙可以進修自創下文的內容。

1、獲得此次要求的URL

String requestUrl = request.getScheme() //以後鏈接應用的協定
    +"://" + request.getServerName()//辦事器地址 
    + ":" + request.getServerPort() //端標語 
    + request.getContextPath() //運用稱號，假如運用稱號為
    + request.getServletPath() //要求的絕對url 
    + "?" + request.getQueryString(); //要求參數

舉例：

http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1
<Context path="world" docBase="/home/webapps" debug="0" reloadable="true"/>

request.getScheme() = "http";
request.getServerName() = "127.0.0.1";
request.getServerPort() = "8080";
request.getContextPath() = "world";
request.getServletPath() = "index.jsp";
request.getQueryString() = "name=lilei&sex=1";

http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1
<Context path="" docBase="/home/webapps" debug="0" reloadable="true"/>

request.getScheme() = "http";
request.getServerName() = "127.0.0.1";
request.getServerPort() = "8080";
request.getContextPath() = "";
request.getServletPath() = "world/index.jsp";
request.getQueryString() = "name=lilei&sex=1";

2、獲得辦事器根途徑

<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%>

應用以下：

<head>
<link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/icon.css">
<link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/base.css">
<script src="<%=basePath%>static/javascript/framework/jquery.min.js"></script>
<script src="<%=basePath%>static/javascript/framework/jquery.easyui.min.js"></script>
<script src="<%=basePath%>static/javascript/framework/easyui-lang-zh_CN.js"></script>
<script src="<%=basePath%>static/javascript/framework/easyui-util.js"></script>
</head>

以上就是Java獲得此次要求URL和辦事器根途徑的辦法，願望對年夜家的進修有所贊助。

3. 當 progress 算出的間隔到3 時，須要繪制棕色半圓弧形，棕色矩形，白色矩形；

4. 當 progress 算出的間隔到頭時，須要繪制棕色半圓弧形，棕色矩形；（可以歸並到3中）

起首依據進度條的寬度和以後進度、總進度算出以後的地位：

//mProgressWidth為進度條的寬度，依據以後進度算出進度條的地位 
mCurrentProgressPosition = mProgressWidth * mProgress / TOTAL_PROGRESS;

然後依照下面的邏輯停止繪制，個中須要盤算上圖中的白色弧角角度，盤算辦法以下：

// 單邊角度 
int angle = (int) Math.toDegrees(Math.acos((mArcRadius - mCurrentProgressPosition)/ (float) mArcRadius));

Math.acos() －反余弦函數；
Math.toDegrees() －弧度轉化為角度，Math.toRadians 角度轉化為弧度
所以圓弧的肇端點為：

int startAngle = 180 - angle;

圓弧劃過的角度為：
2 * angle

這一塊的代碼以下：

// mProgressWidth為進度條的寬度，依據以後進度算出進��條的地位 
mCurrentProgressPosition = mProgressWidth * mProgress / TOTAL_PROGRESS; 
// 即以後地位在圖中所示1規模內 
if (mCurrentProgressPosition < mArcRadius) { 
  Log.i(TAG, "mProgress = " + mProgress + "---mCurrentProgressPosition = " 
      + mCurrentProgressPosition 
      + "--mArcProgressWidth" + mArcRadius); 
  // 1.繪制白色ARC，繪制orange ARC 
  // 2.繪制白色矩形 
 
  // 1.繪制白色ARC 
  canvas.drawArc(mArcRectF, 90, 180, false, mWhitePaint); 
 
  // 2.繪制白色矩形 
  mWhiteRectF.left = mArcRightLocation; 
  canvas.drawRect(mWhiteRectF, mWhitePaint); 
 
  // 3.繪制棕色 ARC 
  // 單邊角度 
  int angle = (int) Math.toDegrees(Math.acos((mArcRadius - mCurrentProgressPosition) 
      / (float) mArcRadius)); 
  // 肇端的地位 
  int startAngle = 180 - angle; 
  // 掃過的角度 
  int sweepAngle = 2 * angle; 
  Log.i(TAG, "startAngle = " + startAngle); 
  canvas.drawArc(mArcRectF, startAngle, sweepAngle, false, mOrangePaint); 
} else { 
  Log.i(TAG, "mProgress = " + mProgress + "---transfer-----mCurrentProgressPosition = " 
      + mCurrentProgressPosition 
      + "--mArcProgressWidth" + mArcRadius); 
  // 1.繪制white RECT 
  // 2.繪制Orange ARC 
  // 3.繪制orange RECT 
   
  // 1.繪制white RECT 
  mWhiteRectF.left = mCurrentProgressPosition; 
  canvas.drawRect(mWhiteRectF, mWhitePaint); 
   
  // 2.繪制Orange ARC 
  canvas.drawArc(mArcRectF, 90, 180, false, mOrangePaint); 
  // 3.繪制orange RECT 
  mOrangeRectF.left = mArcRightLocation; 
  mOrangeRectF.right = mCurrentProgressPosition; 
  canvas.drawRect(mOrangeRectF, mOrangePaint); 
 
}

接上去再來看葉子部門：
起首依據後果情形根本肯定出曲線函數，尺度函數方程為：y = A(wx+Q)+h，個中w影響周期，A影響振幅，周期T＝ 2 * Math.PI/w;
依據後果可以看出，周期年夜致為總進度長度，所以肯定w＝(float) ((float) 2 * Math.PI /mProgressWidth)；

細心不雅察後果，我們可以發明，葉��飛舞的進程中振幅不是完整分歧的，發生一種參差的後果，既然如斯，我們給葉子界說一個Type，依據Type 肯定分歧的振幅；
我們創立一個葉子對象：

private class Leaf { 
 
   // 在繪制部門的地位 
   float x, y; 
   // 掌握葉子飛舞的幅度 
   StartType type; 
   // 扭轉角度 
   int rotateAngle; 
   // 扭轉偏向--0代表順時針，1代表逆時針 
   int rotateDirection; 
   // 肇端時光(ms) 
   long startTime; 
 }

類型采取列舉停止界說，其實就是用來辨別分歧的振幅：

private enum StartType { 
  LITTLE, MIDDLE, BIG 
}

創立一個LeafFactory類用於創立一個或多個葉子信息：

private class LeafFactory { 
  private static final int MAX_LEAFS = 6; 
  Random random = new Random(); 
 
  // 生成一個葉子信息 
  public Leaf generateLeaf() { 
    Leaf leaf = new Leaf(); 
    int randomType = random.nextInt(3); 
    // 隨時類型－ 隨機振幅 
    StartType type = StartType.MIDDLE; 
    switch (randomType) { 
      case 0: 
        break; 
      case 1: 
        type = StartType.LITTLE; 
        break; 
      case 2: 
        type = StartType.BIG; 
        break; 
      default: 
        break; 
    } 
    leaf.type = type; 
    // 隨機肇端的扭轉角度 
    leaf.rotateAngle = random.nextInt(360); 
    // 隨機扭轉偏向（順時針或逆時針） 
    leaf.rotateDirection = random.nextInt(2); 
    // 為了發生交織的感到，閃開始的時光有必定的隨機性 
    mAddTime += random.nextInt((int) (LEAF_FLOAT_TIME * 1.5)); 
    leaf.startTime = System.currentTimeMillis() + mAddTime; 
    return leaf; 
  } 
 
  // 依據最年夜葉子數發生葉子信息 
  public List<Leaf> generateLeafs() { 
    return generateLeafs(MAX_LEAFS); 
  } 
 
  // 依據傳入的葉子數目發生葉子信息 
  public List<Leaf> generateLeafs(int leafSize) { 
    List<Leaf> leafs = new LinkedList<Leaf>(); 
    for (int i = 0; i < leafSize; i++) { 
      leafs.add(generateLeaf()); 
    } 
    return leafs; 
  } 
}

界說兩個常亮分離記載中等振幅和之間的振幅差：

// 中等振幅年夜小 
private static final int MIDDLE_AMPLITUDE = 13; 
// 分歧類型之間的振幅差距 
private static final int AMPLITUDE_DISPARITY = 5; 
[html] view plain copy 在CODE上檢查代碼片派生到我的代碼片
// 中等振幅年夜小 
private int mMiddleAmplitude = MIDDLE_AMPLITUDE; 
// 振幅差 
private int mAmplitudeDisparity = AMPLITUDE_DISPARITY;

有了以上信息，我們則可以獲得到葉子的Y值：

// 經由過程葉子信息獲得以後葉子的Y值 
private int getLocationY(Leaf leaf) { 
  // y = A(wx+Q)+h 
  float w = (float) ((float) 2 * Math.PI / mProgressWidth); 
  float a = mMiddleAmplitude; 
  switch (leaf.type) { 
    case LITTLE: 
      // 小振幅 ＝ 中等振幅 － 振幅差 
      a = mMiddleAmplitude - mAmplitudeDisparity; 
      break; 
    case MIDDLE: 
      a = mMiddleAmplitude; 
      break; 
    case BIG: 
      // 小振幅 ＝ 中等振幅 + 振幅差 
      a = mMiddleAmplitude + mAmplitudeDisparity; 
      break; 
    default: 
      break; 
  } 
  Log.i(TAG, "---a = " + a + "---w = " + w + "--leaf.x = " + leaf.x); 
  return (int) (a * Math.sin(w * leaf.x)) + mArcRadius * 2 / 3; 
}

接上去，我們開端繪制葉子：

/** 
 * 繪制葉子 
 *  
 * @param canvas 
 */ 
private void drawLeafs(Canvas canvas) { 
  long currentTime = System.currentTimeMillis(); 
  for (int i = 0; i < mLeafInfos.size(); i++) { 
    Leaf leaf = mLeafInfos.get(i); 
    if (currentTime > leaf.startTime && leaf.startTime != 0) { 
      // 繪制葉子－－依據葉子的類型和以後時光得出葉子的（x，y） 
      getLeafLocation(leaf, currentTime); 
      // 依據時光盤算扭轉角度 
      canvas.save(); 
      // 經由過程Matrix掌握葉子扭轉 
      Matrix matrix = new Matrix(); 
      float transX = mLeftMargin + leaf.x; 
      float transY = mLeftMargin + leaf.y; 
      Log.i(TAG, "left.x = " + leaf.x + "--leaf.y=" + leaf.y); 
      matrix.postTranslate(transX, transY); 
      // 經由過程時光聯系關系扭轉角度，則可以直接經由過程修正LEAF_ROTATE_TIME調理葉子扭轉快慢 
      float rotateFraction = ((currentTime - leaf.startTime) % LEAF_ROTATE_TIME) 
          / (float) LEAF_ROTATE_TIME; 
      int angle = (int) (rotateFraction * 360); 
      // 依據葉子扭轉偏向肯定葉子扭轉角度 
      int rotate = leaf.rotateDirection == 0 ? angle + leaf.rotateAngle : -angle 
          + leaf.rotateAngle; 
      matrix.postRotate(rotate, transX 
          + mLeafWidth / 2, transY + mLeafHeight / 2); 
      canvas.drawBitmap(mLeafBitmap, matrix, mBitmapPaint); 
      canvas.restore(); 
    } else { 
      continue; 
    } 
  } 
}

最初，向外層裸露幾個接口：

/** 
 * 設置中等振幅 
 *  
 * @param amplitude 
 */ 
public void setMiddleAmplitude(int amplitude) { 
  this.mMiddleAmplitude = amplitude; 
} 
 
/** 
 * 設置振幅差 
 *  
 * @param disparity 
 */ 
public void setMplitudeDisparity(int disparity) { 
  this.mAmplitudeDisparity = disparity; 
} 
 
/** 
 * 獲得中等振幅 
 *  
 * @param amplitude 
 */ 
public int getMiddleAmplitude() { 
  return mMiddleAmplitude; 
} 
 
/** 
 * 獲得振幅差 
 *  
 * @param disparity 
 */ 
public int getMplitudeDisparity() { 
  return mAmplitudeDisparity; 
} 
 
/** 
 * 設置進度 
 *  
 * @param progress 
 */ 
public void setProgress(int progress) { 
  this.mProgress = progress; 
  postInvalidate(); 
} 
 
/** 
 * 設置葉子飄完一個周期所花的時光 
 *  
 * @param time 
 */ 
public void setLeafFloatTime(long time) { 
  this.mLeafFloatTime = time; 
} 
 
/** 
 * 設置葉子扭轉一周所花的時光 
 *  
 * @param time 
 */ 
public void setLeafRotateTime(long time) { 
  this.mLeafRotateTime = time;

這些接口用來干嗎呢？用於把我們的動效做成完整可手動調理的，如許做有甚麼利益呢？
1. 加倍便於產物、射雞濕檢查後果，防止YY，本身手動調理，不會湧現要你一遍遍的改參數裝置、檢查、再改、再檢查... ... N遍以後說 “這似乎不是我想要的” -- 剎時天崩地裂，昏天黑地，感到被全球擯棄；
2. 便於表現你是一個斟酌周全，思想周密，會編程、會設計的藝術家，固然這純屬YY，重要照樣便利年夜家；

如斯一來，射雞濕們只須要赓續的調理便可及時的看到展示的後果，最初只須要把終究的參數反應過去便可，萬事年夜吉，依然如故；
固然，假如對方是個英俊的妹子，而你又苦於沒無機會搭赸，以上內容就當我沒說，縱情的不按請求寫吧，她確定會自動找你的，說不定連飯都反過去請了... ...

好啦，言歸正傳，完成掃尾部門，我們讓一切的參數都可調理起來：
把剩下的layout 和activity貼出來：

    OnClickListener {

    public void handleMessage(Message msg) { 
      switch (msg.what) {
