2.String sql
    
String sql = "select * from test where time between ? and ?";
    
3.build Parameter

5.build DataSetParameter  [创建数据集合的参数]
      int timeStart = xxx;              int timeEnd = xxx;       void setReportParameterValue(ReportDesignHandle designHandle) throws SemanticException, IOException{((ScalarParameterHandle) designHandle.findParameter("startTimeStr")).setDefaultValue(timeStart+ "");((ScalarParameterHandle) designHandle.findParameter("endTimeStr")).setDefaultValue(timeEnd+ "");designHandle.save();       }

                reportEngine.shutdown();
Platform.shutdown();
