前端、后台和数据库间数据的交互及基本操作（spring-mybatis-mvc）
前言：项目中使用到了jquery-1.8.3.js框架。
mysql数据库设计；
配置pom.xml ：

1、配置数据库连接属性：（spring.xml）
#mysql
mysql_name=数据库账户
mysql_pwd=数据库密码
mysql_url=jdbc:mysql://localhost:3306/数据库名称?characterEncoding=utf-8&serverTimezone=Asia/Shanghai
2、配置Mybatis配置文件：
3、配置Spring.xml配置文件：
classpath:db.properties
4、配置springmvc.xml:
text/html;charset=utf-8
5 、配置实现对数据库进行增删改查操作的.xml文件（实现dao层内方法）：
insert into t_student
(
name,student_no,sex,age,birthday,height,weight,address
)
values
(
#{name},#{studentNo},#{sex},${age},#{birthday},${height},${weight},#{address}
)
update t_student set
name=#{name},
student_no=#{studentNo},
sex=#{sex},age=${age},
birthday=#{birthday},
height=${height},
weight=${weight},
address=#{address}
where id=#{id}
delete from t_student where id = ${id}
6、配置好web.xml配置文件：
Archetype Created Web Application
contextConfigLocation
classpath:spring.xml
org.springframework.web.context.ContextLoaderListener
springMvc
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:springMvc.xml
1
springMvc
/
default
*.js
7、编写好静态页面index.xml(以下是写好的)：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
信息
学号
名称
年龄
性别
出生日期
身高
体重
家庭住址
操作
8、controller层：
package com.www.controller;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import java.text.SimpleDateFormat;
import java.util.Date;
public class BaseController {
@InitBinder
public void initBinder(ServletRequestDataBinder binder){
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
/**
* 重新注册客户端编辑器
* 寻找与实体中Date.class属性名称和参数名称相同的数据，在通过sdf的方式进行转换为Date
*/
binder.registerCustomEditor(Date.class,new CustomDateEditor(sdf,true));
}
}
package com.www.controller;
import com.www.entity.TStudent;
import com.www.service.TStudentServiceImpl;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.annotation.Resource;
import java.util.List;
import java.util.Map;
@Controller
@RequestMapping("/tsc")
public class TStudentController extends BaseController{
@Resource(name = "TStudentServiceImpl")
private TStudentServiceImpl tssi;
@RequestMapping("/index")
public String index(){
return "/student/index";
}
/**
*
*/
@RequestMapping("/find")
@ResponseBody
public List find(TStudent ts) {
List list = tssi.find(ts);
return list;
}
/**
*
*/
@RequestMapping("/saveOrEdit")
@ResponseBody
public Map saveOrEdit(TStudent ts){
return tssi.saveOrEdit(ts);
}
/**
*
*/
@RequestMapping("/edit/{id}")
@ResponseBody
public TStudent edit(@PathVariable(value = "id") int id){
TStudent ts = tssi.get(id);
return ts;
}
/**
*
*/
@RequestMapping("/delete/{id}")
@ResponseBody
public Map delete(@PathVariable(value = "id") int id){
return tssi.delete(id);
}
}
9、dao层：
package com.www.dao;
import com.www.entity.TStudent;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface TStudentDao {
List find(TStudent ts);
int insert(TStudent ts);
int update(TStudent ts);
//不是对象传值 ， 需@Param
int remove(@Param(value = "id") int id);
}
10、实体类（entity）：
package com.www.entity;
import com.alibaba.fastjson.annotation.JSONField;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
@Data
public class TStudent implements Serializable {
private static final long serialVersionUID = -3252363464563436L;
private Integer id;
private String name;
private String password;
private String sex;
@JSONField(format = "yyyy-MM-dd")
private Date birthday;
private Date createDate;
private String studentNo;
private String address;
private String status;
private Integer age;
private Integer weight;
private Integer height;
private Integer classId;
public static long getSerialVersionUID() {
return serialVersionUID;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
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 getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
public String getStudentNo() {
return studentNo;
}
public void setStudentNo(String studentNo) {
this.studentNo = studentNo;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Integer getWeight() {
return weight;
}
public void setWeight(Integer weight) {
this.weight = weight;
}
public Integer getHeight() {
return height;
}
public void setHeight(Integer height) {
this.height = height;
}
public Integer getClassId() {
return classId;
}
public void setClassId(Integer classId) {
this.classId = classId;
}
@Override
public String toString() {
return "TStudent{" +
"id=" + id +
", name='" + name + '\'' +
", password='" + password + '\'' +
", sex='" + sex + '\'' +
", birthday=" + birthday +
", createDate=" + createDate +
", studentNo='" + studentNo + '\'' +
", address='" + address + '\'' +
", status='" + status + '\'' +
", age=" + age +
", weight=" + weight +
", height=" + height +
", classId=" + classId +
'}';
}
}
11、service层：
package com.www.service;
import com.www.dao.TStudentDao;
import com.www.entity.TStudent;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@Service
public class TStudentServiceImpl {
@Autowired
private TStudentDao tsd;
public List find(TStudent ts){
List list = tsd.find(ts);
return list;
}
public Map saveOrEdit(TStudent ts) {
Map map = new HashMap<>();
int i = 0;
if (StringUtils.isEmpty(ts.getId())){
i = tsd.insert(ts);
map.put("is",i>0);
map.put("msg","保存"+(i>0?"成功":"失败"));
}else {
i = tsd.update(ts);
map.put("is",i>0);
map.put("msg","编辑"+(i>0?"成功":"失败"));
}
return map;
}
public TStudent get(int id) {
TStudent ts = new TStudent();
ts.setId(id);
List list = this.find(ts);
ts = list.size()>0? list.get(0):null;
return ts;
}
public Map delete(int id) {
Map map = new HashMap<>();
int i = tsd.remove(id);
map.put("msg","删除"+(i>0?"成功!":"失败!"));
map.put("is",i>0);
return map;
}
}
