2.action（必須有set和get）
public String execute() throws Exception{if(classs.length()>0){if(course.length()>0){scorelist=mgr.findScoreByClassandCourse(classs, course);//一個班的某一科成績}else{scorelist=mgr.findScoreByClass(classs);//一個班的所有成績}}else if(number.length()>0){if(course.length()>0){scorelist=mgr.findScoreByNumberandCourse(number, course);//一個人的某一科成績}else{scorelist=mgr.findScoreByNumber(number);//一個人的所有成績}}else if(name.length()>0){if(course.length()>0){scorelist=mgr.findScoreByNumberandCourse(number, course);//一個人的某一科成績}else{scorelist=mgr.findScoreByName(name);//一個人的所有成績}}else if(course.length()>0){scorelist=mgr.findScoreByCourse(course);}else {scorelist.clear();}return SUCCESS;}
