环境搭建
(1)pom.xml

(2)实体类下的Brand类
package com.itheima.pojo;
public class Brand {
// id 主键
private Integer id;
// 品牌名称
private String brandName;
// 企业名称
private String companyName;
// 排序字段
private Integer ordered;
// 描述信息
private String description;
// 状态:0:禁用 1:启用
private Integer status;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getBrandName() {
return brandName;
}
public void setBrandName(String brandName) {
this.brandName = brandName;
}
public String getCompanyName() {
return companyName;
}
public void setCompanyName(String companyName) {
this.companyName = companyName;
}
public Integer getOrdered() {
return ordered;
}
public void setOrdered(Integer ordered) {
this.ordered = ordered;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Integer getStatus() {
return status;
}
//逻辑视图
public String getStatusStr(){
if (status == null){
return "未知";
}
return status == 0 ? "禁用":"启用";
}
public void setStatus(Integer status) {
this.status = status;
}
@Override
public String toString() {
return "Brand{" +
"id=" + id +
", brandName='" + brandName + '\'' +
", companyName='" + companyName + '\'' +
", ordered=" + ordered +
", description='" + description + '\'' +
", status=" + status +
'}';
}
}
(3) BrandMapper.java 与 BrandMapper.xml
(4)SqlSessionFactoryUtils.java(mybatis-config.xml处是你自己的文件路径)
(5)由于我们在用一种很新的方法写servlet
package com.itheima.web.servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
/*替换HttpServlet,根据请求路径的最后一段,进行方法分发(get or post)*/
public class BaseServlet extends HttpServlet {
//根据请求路径的最后一行进行分发
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//1.获取请求路径
String uri = req.getRequestURI();/* /brand-case/brand/selectAll */
//2.获取最后一段路径,方法名
int index = uri.lastIndexOf('/');/*从后开始获取某个字符第一次出现的位置索引*/
String methodName = uri.substring(index+1);//从该索引位置进行剪切,至字符串的最有一位(包含'/')
//执行方法
//1.获取brandservlet的字节码对象class
Class<? extends BaseServlet> cls = this.getClass();
//2.获取method对象
try {
Method cm = cls.getMethod(methodName,HttpServletRequest.class,HttpServletResponse.class);
//3.执行方法
try {
cm.invoke(this,req,resp);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
}
}
(6)BrandServletImpl.java 定义接口
package com.itheima.service.impl;
import com.itheima.mapper.BrandMapper;
import com.itheima.pojo.Brand;
import com.itheima.pojo.PageBean;
import com.itheima.service.BrandService;
import com.itheima.util.SqlSessionFactoryUtils;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import java.util.List;
public class BrandServiceImpl implements BrandService {
//1.创建 SqlSessionFactory 工厂
SqlSessionFactory factory = SqlSessionFactoryUtils.getSqlSessionFactory();
}
(7)PageBean实体类
package com.itheima.pojo;
import java.util.List;
//分页查询
public class PageBean<T> {
//总记录数
private int totalCount;
//当前页数据
private List<T> rows;
public int getTotalCount() {
return totalCount;
}
public void setTotalCount(int totalCount) {
this.totalCount = totalCount;
}
public List<T> getRows() {
return rows;
}
public void setRows(List<T> rows) {
this.rows = rows;
}
}
(8)查询所有
public interface BrandMapper {
// 查询所有
@Select("select * from tb_brand")
@ResultMap("brandResultMap")
List<Brand> selectAll();
}
public class BrandServiceImpl implements BrandService {
//1.创建 SqlSessionFactory 工厂
SqlSessionFactory factory = SqlSessionFactoryUtils.getSqlSessionFactory();
//查询操作
@Override
public List<Brand> selectAll() {
//2.获取SqllSession对象
SqlSession session = factory.openSession();
//3.获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//4.调用方法
List<Brand> brands = mapper.selectAll();
//5.释放资源
session.close();
return brands;
}
}
@WebServlet("/brand/*")
public class BrandServlet extends BaseServlet{
private BrandService brandService = new BrandServiceImpl();
public void selectAll(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//1.调用service查询
List<Brand> brands = brandService.selectAll();
//2.转为JSON
String s = JSON.toJSONString(brands);
//3.写数据
//中文
resp.setContentType("text/json;charset=UTF-8");
resp.getWriter().write(s);
}
}
//分页条件查询
public void selectByPageAndCondition(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//1. 接收 当前页码 和 每页展示条数 url?currentPage=1&pageSize=5
String _currentPage = request.getParameter("currentPage");
String _pageSize = request.getParameter("pageSize");
int currentPage = Integer.parseInt(_currentPage);
int pageSize = Integer.parseInt(_pageSize);
// 获取查询条件对象
BufferedReader br = request.getReader();
String params = br.readLine();//json字符串
//转为 Brand
Brand brand = JSON.parseObject(params, Brand.class);
//2. 调用service查询
PageBean<Brand> pageBean = brandService.selectByPageAndCondition(currentPage,pageSize,brand);
//2. 转为JSON
String jsonString = JSON.toJSONString(pageBean);
//3. 写数据
response.setContentType("text/json;charset=utf-8");
response.getWriter().write(jsonString);
}
//查询分页数据
selectAll(){
//查询所有数据
axios({
method:"post",
url:"http://localhost:8080/brand-case/brand/selectByPageAndCondition?currentPage="+this.currentPage+"&pageSize="+this.pageSize,
data:this.brand
}).then(resp =>{
this.tableData = resp.data.rows;//{rows:[],totalCount:[]}
this.tableCount = resp.data.totalCount;
})
},
(9)data(){}
data() {
return {
//默认每页5条数据
pageSize:5,
//总记录数
tableCount:100,
// 当前页码
currentPage: 1,
// 添加数据对话框是否展示的标记
dialogVisible: false,
dialogVisible2: false,
tableData:{},
// 品牌模型数据
brand: {
status: '',
brandName: '',
companyName: '',
id:"",
ordered:"",
description:""
},
// 复选框选中数据集合
multipleSelection: [],
selectByIds:[]
}
(10)添加数据
//添加
@Insert("insert into tb_brand values(null,#{brandName},#{companyName},#{ordered},#{description},#{status})")
void add(Brand brand);
//添加操作
@Override
public void add(Brand brand) {
//2.获取SqlSession对象
SqlSession session = factory.openSession();
//3.获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//4.调用方法
mapper.add(brand);
session.commit();
session.close();
}
public void add(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//接受品牌数据(JSON格式)
BufferedReader br = req.getReader();
String params = br.readLine();//读取一行,JSON全部数据就是一行
//转为Brand对象
Brand brand = JSON.parseObject(params, Brand.class);
//调用service添加
brandService.add(brand);
//响应数据成功的标识
resp.getWriter().write("success");
}
// 添加数据
addBrand(){

var _this = this;
axios({

data:_this.brand
}).then(function (resp){
if(resp.data == "success"){
//添加成功
//关闭窗口
_this.dialogVisible = false;
//查询所有
_this.selectAll();
_this.$message({
message:'添加成功了少年郎',
type:'success'
});
}
})
},
(11)修改方法
//修改
@Update("update tb_brand set brand_name = #{brandName},company_name = #{companyName},ordered = #{ordered},description = #{description},status = #{status} where id = #{id}")
void update(Brand brand);
//修改操作
@Override
public void update(Brand brand){
//获取SQLSession对象
SqlSession session = factory.openSession();
//获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);

}
updateBrand(){
//修改数据
//添加axios请求,添加数据
var _this = this;
axios({
method:"post",
url:"http://localhost:8080/brand-case/brand/update",
data:_this.brand
}).then(function (resp){
if(resp.data == "success"){
//修改成功
//关闭窗口
_this.dialogVisible2 = false;
//查询所有
_this.selectAll();
_this.$message({
message:'修改成功了少年郎',
type:'success'
});
}
})
},
(12) 删除方法
//删除
@Delete("delete from tb_brand where id = #{id}")
void deleteById(int id);
//删除操作
@Override
public void deleteById(int id){
//获取SQLSession对象
SqlSession session = factory.openSession();
//获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//调用方法
mapper.deleteById(id);
session.commit();
session.close();
}
//删除
public void deleteById(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//接受品牌数据(JSON格式)
BufferedReader br = req.getReader();
String params = br.readLine();//读取一行,JSON全部数据就是一行
//转为 int
int id = JSON.parseObject(params,int.class);
//调用service修改
brandService.deleteById(id);
resp.getWriter().write("success");
}
//删除数据
deleteById(index,row) {
// 弹出确认提示框
this.$confirm('此操作将删除该数据, 是否继续?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
//用户点击确认按钮
//2. 发送AJAX请求
var _this = this;
// 发送ajax请求,添加数据
axios({
method:"post",
url:"http://localhost:8080/brand-case/brand/deleteById",
data:row.id
}).then(function (resp) {
if(resp.data == "success"){
//删除成功
// 重新查询数据
_this.selectAll();
// 弹出消息提示
_this.$message({
message: '删除成功了少年郎',
type: 'success'
});
}
})
}).catch(() => {
//用户点击取消按钮
this.$message({
type: 'info',
message: '已取消删除'
});
});
},
(13) 批量删除方法
//批量删除
void deleteByIds(@Param("ids") int[] ids);
BrandMapper.xml下添加
<delete id="deleteByIds">
delete from tb_brand where id in
<foreach collection="ids" item="id" separator="," open="(" close=")">
#{id}
</foreach>
</delete>
//批量删除操作
@Override
public void deleteByIds(int[] ids){
//获取SQLSession对象
SqlSession session = factory.openSession();
//获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//调用方法
mapper.deleteByIds(ids);
session.commit();
session.close();
}
//批量删除
public void deleteByIds(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//接受品牌数据(JSON格式)
BufferedReader br = req.getReader();
String params = br.readLine();//读取一行,JSON全部数据就是一行
//转为Brand对象
int[] ids = JSON.parseObject(params, int[].class);
//调用service修改
brandService.deleteByIds(ids);
resp.getWriter().write("success");
}
deleteByIds() {
//console.log(this.multipleSelection);
//1.创建id数组[1,2,3],从multipleSelection模型里面来的数据
this.$confirm('此操作将永久删除该文件, 是否继续?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
for (let i = 0; i < this.multipleSelection.length; i++) {
let element = this.multipleSelection[i];
//获取遍历后得到id值
this.selectByIds[i] = element.id;
}
var _this = this;
axios({
method: "post",
url: "http://localhost:8080/brand-case/brand/deleteByIds",
data: _this.selectByIds
}).then(resp => {
if (resp.data == "success") {
//录入成功,关闭窗口,并且重新查询数据
_this.selectAll();
_this.$message({
message: '成功删除数据',
type: 'success'
});
}else{
_this.$message({
message: '没有数据可以删除',
type: 'info'
});
}
})
}).catch(() => {
this.$message({
type: 'info',
message: '已取消删除'
});
});
},
(14)分页查询(和普通查询方法一样会被 “条件分页查询替代” )
//分页查询-查询当前页
@Select("select * from tb_brand limit #{begin} , #{size}")
@ResultMap("brandResultMap")
List<Brand> selectByPage(@Param("begin") int begin,@Param("size") int size);
//分页查询-总记录数
@Select("select count(*) from tb_brand")
int selectTotalCount();
@Override
public PageBean<Brand> selectByPage(int currentPage, int pageSize) {
//获取SQLSession对象
SqlSession session = factory.openSession();
//获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//计算开始索引
int begin = (currentPage-1)*pageSize;
//计算总体数据数量
int size = pageSize;
//查询总数
int totalCount = mapper.selectTotalCount();
//调用方法
List<Brand> rows = mapper.selectByPage(begin, size);
//封装函数
PageBean<Brand> pageBean = new PageBean<>();
pageBean.setTotalCount(totalCount);
pageBean.setRows(rows);
session.close();
return pageBean;
}
//分页查询
public void selectByPage(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
/*接收参数
* currentPage:当前页码
* PageSize:每页条数
* http://localhost:8080/brand-case/brand/selectByPage?currentPage=1&pageSize=5
* */
String _currentPage = req.getParameter("currentPage");
String _pageSize = req.getParameter("pageSize");
int currentPage = Integer.parseInt(_currentPage);
int pageSize = Integer.parseInt(_pageSize);
//2. 调用service查询
PageBean<Brand> pageBean = brandService.selectByPage(currentPage, pageSize);
//2.转为JSON
String s = JSON.toJSONString(pageBean);
//3.写数据
//中文
resp.setContentType("text/json;charset=UTF-8");
resp.getWriter().write(s);
}
(15)条件分页查询
//条件查询-分页查询
List<Brand> selectByPageAndCondition(@Param("begin") int begin,@Param("size") int size,@Param("brand") Brand brand);
//总记录数-满足查询条件的
int selectTotalCountByCondition(Brand brand);
<select id="selectByPageAndCondition" resultMap="brandResultMap">

@Override
public PageBean<Brand> selectByPageAndCondition(int currentPage, int pageSize, Brand brand) {
//获取SQLSession对象
SqlSession session = factory.openSession();
//获取brandmapper
BrandMapper mapper = session.getMapper(BrandMapper.class);
//计算开始索引
int begin = (currentPage-1)*pageSize;
//计算总体数据数量
int size = pageSize;
//处理模糊算法
String brandName = brand.getBrandName();
if (brandName != null && brandName.length() > 0){
brand.setBrandName("%"+brandName+"%");
}
String companyName = brand.getCompanyName();
if (companyName != null && companyName.length() > 0){
brand.setCompanyName("%"+companyName+"%");
}

String jsonString = JSON.toJSONString(pageBean);
//3. 写数据
response.setContentType("text/json;charset=utf-8");
response.getWriter().write(jsonString);
}
//分页
//每页条数发生变化
handleSizeChange(val) {
// console.log(`每页 ${val} 条`);
//重新设置每页条数
this.pageSize = val;
this.selectAll();
