举例说明：
后台有一个对象 User ，结构如下：
后台有一个对象 User ，结构如下：
public class User{
private String username;
private List<PhotoDo> photo;
..get ....set.....
}
public class PhotoDo{
private String id;
private String name;
...get...set...
}
Controller中接受方法 getUser
@reqeustMapping("/getUser")
public void getUser(User user){
...实现方法...
}
前台Form这么写：
<form>
<input type="text" name="username" aciton="..">
<input type="text" name="photo[0].id">
<input type="text" name="photo[0].name">
<input type="text" name="photo[1].id">
<input type="text" name="photo[1].name">
<input type="text" name="photo[2].id">
<input type="text" name="photo[2].name">
</form>
这里下标可以用var = status-1来解决
第二个例子:
对象Cltc和list实体类
package com.ABC.pojo;
import java.util.Date;
public class Cltc {
private Integer id;
private Integer classid;//班级id
private Integer teacherid;//教师id
private Integer courseid;//课程id
private Date time;//排课时间
private Date start;//开始上课时间
private Date end;//结束上课时间
private Classinfo classinfo;//班级 排课状态和 结课状态 入学时间
public Classinfo getClassinfo() {
return classinfo;
}
public void setClassinfo(Classinfo classinfo) {
this.classinfo = classinfo;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getClassid() {
return classid;
}
public void setClassid(Integer classid) {
this.classid = classid;
}
public Integer getTeacherid() {
return teacherid;
}
public void setTeacherid(Integer teacherid) {
this.teacherid = teacherid;
}
public Integer getCourseid() {
return courseid;
}
public void setCourseid(Integer courseid) {
this.courseid = courseid;
}
public Date getTime() {
return time;
}
public void setTime(Date time) {
this.time = time;
}
public Date getStart() {
return start;
}
public void setStart(Date start) {
this.start = start;
}
public Date getEnd() {
return end;
}
public void setEnd(Date end) {
this.end = end;
}
@Override
public String toString() {
return "Cltc [id=" + id + ", classid=" + classid + ", teacherid=" + teacherid + ", courseid=" + courseid
+ ", time=" + time + ", start=" + start + ", end=" + end + ", classinfo=" + classinfo + "]";
}
}
