Springboot+微信小程序
项目描述：在微信小程序中通过与Springboot操作数据库实现登录验证，其中我是用springboot整合mybatis操作数据库
微信小程序代码：`
account.wxml
account.js
Page({
data: {
username:'',
password:'',
},
formSumbit:function (e) {
console.log("点击提交按钮");
this.setData({
username: e.detail.value.username,
password: e.detail.value.password
})
},
onLoad: function (options) {
console.log("******");
var that = this;
wx.request({
url:'http://localhost:8080/login', //服务器地址
menthod: "GET",
header: {
'content-type': 'application/json'
},
data: {
'username':that.data.username,
'password': that.data.password
},
success:function (res) {
console.log(".....回调函数....." +res.data );
var resData=res.data;
if(resData==true){
wx:wx.showToast({
title: '登录成功',
duration: 2000,
})
}else{
wx:wx.showToast({
title: '登录失败',
duration: 2000,
})
}
}
})
},
formRest: function () {
console.log("点击了重置")
},
onReady: function () {
console.log("onReady")
},
onShow: function () {
console.log("onShow")
},
onHide: function () {
console.log("onHide")
},
onUnload: function () {
console.log("onUnload")
},
onPullDownRefresh: function () {
console.log("onPullDownRefresh")
},
onReachBottom: function () {
console.log("onReachBottom")
},
onShareAppMessage: function () {
console.log("onShareAppMessage")
}
})
account.wxss

}
.btn2{

}
我使用eclipse安装一个springboot的插件，也可以使用idea,都一样，下面我以eclipse为例
安装插件这里我就不写了百度有很多教程，下面这个链接里面也有

springboot代码：
新建一个springboot项目file>new >Spring Starter Project
如果没找到Spring Starter Project可以去Other中搜索
pom.xml

Demo1Application.java
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
@SpringBootApplication
public class Demo1Application {
public static void main(String[] args) {
SpringApplication.run(Demo1Application.class, args);
}
}
配置文件
application.properties
spring.datasource.url = jdbc:mysql://localhost:3306/ssm
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driverClassName=com.mysql.jdbc.Driver
通过逆向工程生成mapper与mapper.xml和实体类
点击提取逆向工程项目+sql文件 提取码：9eze（自己新建一个数据库然后在运行sql文件,我的数据名为ssm,如果不知道怎么去改逆向工程代码，数据库名就命名跟我一样，就不用改了）
下面就是改数据库名，msyql用户名跟密码的地方
下面我写UserMapper.xml与UserMapper.java的原因是因为我要通过用户名查找用户，这个方法逆向工程没有自动生成，所以要自己加，下面我备注有注释
UserMapper.java
package com.example.demo.dao;
import com.example.demo.pojo.User;
import com.example.demo.pojo.UserExample;
import com.example.demo.pojo.UserKey;
import java.util.List;
import org.apache.ibatis.annotations.Mapper;
/*import org.apache.ibatis.annotations.Param;*/
@Mapper
public interface UserMapper {
int countByExample(UserExample example);
int deleteByExample(UserExample example);
int deleteByPrimaryKey(UserKey key);
int insert(User record);
int insertSelective(User record);
// 通过用户名查找用户。自己加的
User selectUser(String username);
List selectByExample(UserExample example);
User selectByPrimaryKey(int key);
/*int updateByExampleSelective(@Param("record") User record, @Param("example") UserExample example);
int updateByExample(@Param("record") User record, @Param("example") UserExample example);
*/
int updateByPrimaryKeySelective(User record);
int updateByPrimaryKey(User record);
}
UserMapper.xml
and ${criterion.condition}
and ${criterion.condition} #{criterion.value}
and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}
and ${criterion.condition}
#{listItem}
and ${criterion.condition}
and ${criterion.condition} #{criterion.value}
and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}
and ${criterion.condition}
#{listItem}
id, username, password
delete from user
where id = #{id,jdbcType=INTEGER}
and username = #{username,jdbcType=VARCHAR}
delete from user
insert into user (id, username, password
)
values (#{id,jdbcType=INTEGER}, #{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR}
)
insert into user
id,
username,
password,
#{id,jdbcType=INTEGER},
#{username,jdbcType=VARCHAR},
#{password,jdbcType=VARCHAR},
update user
id = #{record.id,jdbcType=INTEGER},
username = #{record.username,jdbcType=VARCHAR},
password = #{record.password,jdbcType=VARCHAR},
update user
set id = #{record.id,jdbcType=INTEGER},
username = #{record.username,jdbcType=VARCHAR},
password = #{record.password,jdbcType=VARCHAR}
update user
password = #{password,jdbcType=VARCHAR},
where id = #{id,jdbcType=INTEGER}
and username = #{username,jdbcType=VARCHAR}
update user
set password = #{password,jdbcType=VARCHAR}
where id = #{id,jdbcType=INTEGER}
and username = #{username,jdbcType=VARCHAR}
实体层就不用改了，直接用逆向工程生成的，我就省略不写了
服务层：
UserService.java
package com.example.demo.service;
import com.example.demo.pojo.User;
public interface UserService {
User selectUser(String username);
User selectByPrimaryKey(int id);
}
UserServiceImpl.java
package com.example.demo.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.example.demo.dao.UserMapper;
import com.example.demo.pojo.User;
@Service
public class UserServiceImpl implements UserService {
@Autowired(required=false)
private UserMapper userMapper;
@Override
public User selectUser(String username) {
System.out.println("-------");
// TODO Auto-generated method stub
//根据用户名查找用户信息
return userMapper.selectUser(username);
}
@Override
public User selectByPrimaryKey(int id) {
// TODO Auto-generated method stub
User user=userMapper.selectByPrimaryKey(1);
return user;
}
}
控制层：
UserController.java
package com.example.demo.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.example.demo.pojo.User;
import com.example.demo.service.UserService;
@RestController
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/login")
public boolean login(String username, String password){
System.out.println ( "微信小程序调用接口！！！用户名:" + username + "密码:" + password );
User user=userService.selectUser(username);
if(user!=null) {
String password1=user.getPassword();
if(password1.equals(password)) {
System.out.println("登录成功");
return true;
}else {
System.out.println("密码错误");
return false;
}
}else {
System.out.println("用户名不存在");
return false;
}
}
@RequestMapping("/selectById")
public User selectById(int id) {
System.out.println("*******");
User user=userService.selectByPrimaryKey(id);
return user;
}
}
项目结构：
点击运行Demo1Application.java文件
如下图：
然后到微信开发者工具account.wxml中点击登录
微信开发者工具控制台：
eclipse控制台：
到此项目能运行成功
