以下是一个简单的JavaWeb职业技能考试的示例:
1. 创建考试题目的数据库表
```sql
CREATE TABLE exam_questions (
id INT PRIMARY KEY AUTO_INCREMENT,
question VARCHAR(255) NOT NULL,
option_a VARCHAR(255) NOT NULL,
option_b VARCHAR(255) NOT NULL,
option_c VARCHAR(255) NOT NULL,
option_d VARCHAR(255) NOT NULL,
answer VARCHAR(1) NOT NULL
);
```
2. 插入考试题目数据
```sql
INSERT INTO exam_questions (question, option_a, option_b, option_c, option_d, answer)
VALUES ('What is the capital of France?', 'A. Paris', 'B. London', 'C. Berlin', 'D. Rome', 'A'),
('What is the largest planet in our solar system?', 'A. Jupiter', 'B. Saturn', 'C. Earth', 'D. Mars', 'A'),
('Who painted the Mona Lisa?', 'A. Leonardo da Vinci', 'B. Vincent van Gogh', 'C. Pablo Picasso', 'D. Michelangelo', 'A');
```
3. 创建考试页面exam.jsp
```html
<!DOCTYPE html>
<html>
<head>
<title>JavaWeb职业技能考试</title>
</head>
<body>
<h1>JavaWeb职业技能考试</h1>
<form action="examResult.jsp" method="post">
<%
// 获取考试题目数据
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/exam_db", "root", "password");
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT * FROM exam_questions");
while (rs.next()) {
String question = rs.getString("question");
String optionA = rs.getString("option_a");
String optionB = rs.getString("option_b");
String optionC = rs.getString("option_c");
String optionD = rs.getString("option_d");
%>
<h3><%= question %></h3>
<input type="radio" name="<%= rs.getInt("id") %>" value="A"> <%= optionA %><br>
<input type="radio" name="<%= rs.getInt("id") %>" value="B"> <%= optionB %><br>
<input type="radio" name="<%= rs.getInt("id") %>" value="C"> <%= optionC %><br>
<input type="radio" name="<%= rs.getInt("id") %>" value="D"> <%= optionD %><br>
<%
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (rs != null) rs.close();
if (stmt != null) stmt.close();
if (conn != null) conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
%>
<br>
<input type="submit" value="提交">
</form>
</body>
</html>
```
4. 创建考试结果页面examResult.jsp
```html
<!DOCTYPE html>
<html>
<head>
<title>JavaWeb职业技能考试结果</title>
</head>
<body>
<h1>JavaWeb职业技能考试结果</h1>
<%
// 获取考试结果
int score = 0;
Enumeration<String> parameterNames = request.getParameterNames();
while (parameterNames.hasMoreElements()) {
String questionId = parameterNames.nextElement();
String selectedOption = request.getParameter(questionId);
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/exam_db", "root", "password");
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT answer FROM exam_questions WHERE id = " + questionId);
if (rs.next()) {
String correctAnswer = rs.getString("answer");
if (selectedOption.equals(correctAnswer)) {
score++;
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (rs != null) rs.close();
if (stmt != null) stmt.close();
if (conn != null) conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
%>
<h3>您的得分是:<%= score %></h3>
</body>
</html>
```
5. 部署并运行JavaWeb应用程序,访问exam.jsp页面进行考试。
