1、创建Web项目studentManager，并导入相关Jar包；
2、在web.xml中配置Spring MVC的前端控制器等信息；
3、创建Spring MVC配置文件，并配置组件扫描器和视图解析器；
4、创建com. po.Student类包含属性sno, stname, 成绩列表。
5、编写过滤器解决中文乱码问题（post请求方式）
6、在com. controller创建处理器类，使用复杂POJO完成页面信息的绑定，并在控制台输出学生学号、姓名、各科成绩。
初始页面示例：
代码实现：
代码目录：
com.controller.StudentController类：
package com.controller;import com.po.Course;
import com.po.Student;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;import java.util.List;@Controller
public class StudentController {@RequestMapping("/showStudent")public String showStudent(Student student){String sno = student.getSno();String sname = student.getStname();List<Course> courses = student.getCourses();System.out.println("学生："+sname);System.out.println("学号："+sno);for (int i = 0;i<courses.size();i++){Course course = courses.get(i);System.out.println("课程名称："+course.getCname());System.out.println("分数："+course.getCscore());}return "success";}
}
com.po.Course类：
注：实体类中的get和set方法以及toString方法可以通过快捷键“alt+insert”快捷生成
package com.po;public class Course {private String cname;private int cscore;public String getCname() {return cname;}public void setCname(String cname) {this.cname = cname;}public int getCscore() {return cscore;}public void setCscore(int cscore) {this.cscore = cscore;}@Overridepublic String toString() {return "Course{" +"cname='" + cname + '\'' +", cscore=" + cscore +'}';}
}
com.po.Student类：
package com.po;import java.util.List;public class Student {private String sno;private String stname;private List<Course> courses;public String getSno() {return sno;}public void setSno(String sno) {this.sno = sno;}public String getStname() {return stname;}public void setStname(String stname) {this.stname = stname;}public List<Course> getCourses() {return courses;}public void setCourses(List<Course> courses) {this.courses = courses;}
}
