title: how to get parameter's annotation in java?
body: <p>I'm a new Java programmer. Following is my code:</p>
  
  <pre><code>    public void testSimple1(String lotteryName,
                          int useFrequence,
                          Date validityBegin,
                          Date validityEnd,
                          LotteryPasswdEnum lotteryPasswd,
                          LotteryExamineEnum lotteryExamine,
                          LotteryCarriageEnum lotteryCarriage,
                          @TestMapping(key = "id", csvFile = "lottyScope.csv") xxxxxxxx lotteryScope,
                          @TestMapping(key = "id", csvFile = "lotteryUseCondition.csv") xxxxxxxx lotteryUseCondition,
                          @TestMapping(key = "id", csvFile = "lotteryFee.csv") xxxxxxxx lotteryFee)
  </code></pre>
  
  <p>I want to get all filed's annotations. Some fields are annotated and some ain't.</p>
  
  <p>I know how to use <code>method.getParameterAnnotations()</code> function, but it just returns three annotations.</p>
  
  <p>I don't know how to correspond them. </p>
  
  <p>I expect the following result:</p>
  
  <pre><code>lotteryName - none
  useFrequence- none
  validityBegin -none
  validityEnd -none
  lotteryPasswd -none
  lotteryExamine-none
  lotteryCarriage-none
  lotteryScope - @TestMapping(key = "id", csvFile = "lottyScope.csv")
  lotteryUseCondition - @TestMapping(key = "id", csvFile = "lotteryUseCondition.csv")
  lotteryFee - @TestMapping(key = "id", csvFile = "lotteryFee.csv")
  </code></pre>
