springMVC+Hibernate简单的Demo

<pre class="java" name="code"><pre class="html" name="code">
最近在学习springMVC，在网上找了一些例子看，最后自己整理出来一个简单的例子，大家一起交流学习下。<img src="https://img-blog.csdn.net/20150214113047962?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvcGFzc2lvbl96aGFuRw==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />

 整体结构就是这样了 需要的jar包我这里面的比较乱，就不贴出来了，一般都是spring的和hibernate的jar包，还有数据库的。

下面贴代码：

Student.Java

package bean;

public class Student{

private String id;
private String name;
private String sex;
private String school_id;
private String edu;
private String tel;
private String addr;
private String sno;

public String getSchool_id() {
return school_id;
}
public void setSchool_id(String school_id) {
this.school_id = school_id;
}

public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getEdu() {
return edu;
}
public void setEdu(String edu) {
this.edu = edu;
}

public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
public String getSno() {
return sno;
}
public void setSno(String sno) {
this.sno = sno;
}
}

Student.hbm.xml 这里用的是配置文件的方式，不是注解。当然注解也可以，当时用注解的时候总是不行，后来改用的配置文件。有朋友使用注解方式搞好了可以教教我。

<?xml version="1.0"?>

StudentController.java 在这个Controller里面写了一个check方法，就是根据现有学生表中的姓名和学号来进行登录，做的时候就是简单添加一下登录验证，需要完善修饰的地方还有很多。
