==================
Spring MVC对象传值
==================
1 实体类
/src/main/java/cn/tedu/springmvc/pojo/Student.java：
public class Student {
private int id;
private String number;
private String name;
private String gender;
private int age;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "Student{" +
"id=" + id +
", number='" + number + '\'' +
", name='" + name + '\'' +
", gender='" + gender + '\'' +
", age=" + age +
'}';
}
}
2 控制器
/src/main/java/cn/tedu/springmvc/controllers/StudentController.java：
@Controller
@RequestMapping("/StudentController")
public class StudentController {
@RequestMapping("/addStudent")
public ModelAndView addStudent(Student student) {
System.out.println("控制器> 添加一名学生");
System.out.println("控制器> 学号：" + student.getNumber());
System.out.println("控制器> 姓名：" + student.getName());
System.out.println("控制器> 性别：" + student.getGender());
System.out.println("控制器> 年龄：" + student.getAge());
return new ModelAndView("/addStudentSuccess.jsp")
.addObject("student", student);
}
}
以对象方式接收前端提交的数据，请求字段对对象属性必须严格一致。
