这里是DTO代码
package dto;
private String name;
private String password;
private String email;
private int rollno;
private String course;
private String branch;
private String gender;
private int year;
private float percent;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getRollno() {
return rollno;
}
public void setRollno(int rollno) {
this.rollno = rollno;
}
public String getCourse() {
return course;
}
public void setCourse(String course) {
this.course = course;
}
public String getBranch() {
return branch;
}
public void setBranch(String branch) {
this.branch = branch;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public float getPercent() {
return percent;
}
public void setPercent(float percent) {
this.percent = percent;
}
@Override
public String toString() {
return "student [name=" + name + ", password=" + password + ", email=" + email + ", rollno=" + rollno
+ ", course=" + course + ", branch=" + branch + ", gender=" + gender + ", year=" + year + ", percent="
+ percent + "]";
}
}
**控制器类**
package controller;
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
boolean flag = false;
RequestDispatcher reqDispatcher = null;
try {
test sd = new test();
sd.setName(request.getParameter("name"));
sd.setPassword(request.getParameter("password"));
sd.setEmail(request.getParameter("email"));
sd.setRollno(Integer.parseInt(request.getParameter("rollno")));
sd.setCourse(request.getParameter("course"));
sd.setBranch(request.getParameter("branch"));
sd.setGender(request.getParameter("gender"));
sd.setYear(Integer.parseInt(request.getParameter("year")));
sd.setPercent(Float.parseFloat(request.getParameter("percent")));
Configuration con = new Configuration().configure().addAnnotatedClass(test.class);
SessionFactory sf = con.buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
session.save(sd);
tx.commit();
flag = true;
} catch (Exception e) {
e.printStackTrace();
}
if (flag) {
reqDispatcher = request.getRequestDispatcher("registered.jsp");
reqDispatcher.forward(request, response);
} else {
reqDispatcher = request.getRequestDispatcher("failure.jsp");
reqDispatcher.forward(request, response);
}
}
}
的hibernate.cfg.xml
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hiber</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hbm2ddl.auto">update</property>
<property name="show_sql">true</property>
<mapping class="dto.test" />
</session-factory>
和我的错误是
HTTP Status 500 - Servlet execution threw an exception
