1.查询全部地址地址

分析：addressBook地址，GET方式，list地址

package com.itheima.reggie.controller;


import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.itheima.reggie.common.R;
import com.itheima.reggie.entity.AddressBook;
import com.itheima.reggie.service.IAddressBookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpSession;
import java.util.List;

/**
 * 

 * 地址管理 前端控制器
 *

 * @author 酒徒
 * @since 2022-09-04
 */
@RestController
@RequestMapping("/addressBook")
public class AddressBookController {

    @Autowired
    private IAddressBookService addressBookService;

    /**
     * 查询全部地址
     * @param session
     * @return
     */
    @GetMapping("/list")
    public R<List<AddressBook>> list(HttpSession session){
        //根据用户id查询地址
        LambdaQueryWrapper<AddressBook> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(AddressBook::getUserId, session.getAttribute("user"));
        List<AddressBook> list = addressBookService.list(queryWrapper);
        return R.success(list);
    }
}

2.添加收货地址

分析：addressBook地址，POST方式

/**
 * 添加地址
 * @param addressBook
 * @param session
 * @return
 */
@PostMapping
public R<String> addressBook(@RequestBody AddressBook addressBook, HttpSession session){
    log.info("addressBook:{}", addressBook);//addressBook:AddressBook(id=null, userId=null, consignee=长津湖, sex=1, phone=13565895624, provinceCode=null, provinceName=null, cityCode=null, cityName=null, districtCode=null, districtName=null, detail=11, label=公司, isDefault=null, createTime=null, updateTime=null, createUser=null, updateUser=null, isDeleted=null)
    addressBook.setUserId((Long)session.getAttribute("user"));
    //添加创建时间和修改时间
    addressBook.setCreateTime(LocalDateTime.now());
    addressBook.setUpdateTime(LocalDateTime.now());
    //添加创建人和修改人
    addressBook.setCreateUser((Long)session.getAttribute("user"));
    addressBook.setUpdateUser((Long)session.getAttribute("user"));
    addressBookService.save(addressBook);
    
    return R.success("添加地址成功");

3.修改地址

1.页面回显

分析：addressBook地址，GET方式，id地址

/**
 * 修改地址——回显数据
 * @param id
 * @return
 */
@GetMapping("/{id}")
public R<AddressBook> huixian(@PathVariable Long id){
    //根据id查询地址信息
    LambdaQueryWrapper<AddressBook> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.eq(AddressBook::getId, id);
    AddressBook addressBook = addressBookService.getOne(queryWrapper);
    return R.success(addressBook);

2.保存地址

分析：addressBook地址，PUT方式

/**
 * 修改地址——保存
 * @param addressBook
 * @param session
 * @return
 */
@PutMapping
public R<String> addressBookupdate(@RequestBody AddressBook addressBook, HttpSession session){
    //设置修改时间
    addressBook.setUpdateTime(LocalDateTime.now());
    //设置修改人
    addressBook.setUpdateUser((Long)session.getAttribute("user"));
    addressBookService.updateById(addressBook);
    return R.success("修改成功");

4.删除地址

分析：addressBook地址，DELETE方式，ids属性

/**
 * 删除地址
 * @param ids
 * @param session
 * @return
 */
@DeleteMapping()
public R<String> addressBook(@PathParam("ids") Long ids, HttpSession session){
    //通过ids删除地址
    LambdaQueryWrapper<AddressBook> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.eq(AddressBook::getId, ids)
            .eq(AddressBook::getUserId, (Long)session.getAttribute("user"));
    addressBookService.remove(queryWrapper);
    return R.success("删除成功");

5.默认地址

1.设置默认地址

从上图分析：addressBook地址，PUT方式，default地址

/**
 * 设置默认地址
 * @param addressBook
 * @param session
 * @return
 */
@PutMapping("/default")
public R<String> defaultSet(@RequestBody AddressBook addressBook, HttpSession session){
    //查询需要修改的addressBook
    //log.info("addressBook:{}", addressBook);//session:AddressBook(id=1565637284313284610, userId=null, consignee=null, sex=null, phone=null, provinceCode=null, provinceName=null, cityCode=null, cityName=null, districtCode=null, districtName=null, detail=null, label=null, isDefault=0, createTime=null, updateTime=null, createUser=null, updateUser=null, isDeleted=null)
    //根据用户id查询所有addressBook信息，将其中的isDefault全部改为0；
    LambdaQueryWrapper<AddressBook> wrapper = new LambdaQueryWrapper<>();
    wrapper.eq(AddressBook::getUserId, session.getAttribute("user"));
    List<AddressBook> addressBooks = addressBookService.list();
    for (AddressBook address : addressBooks) {
        address.setIsDefault(0);
        addressBookService.updateById(address);
    }
    //根据id查询addressBook信息
    LambdaQueryWrapper<AddressBook> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.eq(AddressBook::getId, addressBook.getId());
    AddressBook address = addressBookService.getOne(queryWrapper);
    log.info("address:{}", address);//address:AddressBook(id=1565637284313284610, userId=1, consignee=爱丽丝, sex=0, phone=18535004237, provinceCode=null, provinceName=null, cityCode=null, cityName=null, districtCode=null, districtName=null, detail=55, label=公司, isDefault=0, createTime=2022-09-02T17:46:31, updateTime=2022-09-08T19:15:07, createUser=1, updateUser=1, isDeleted=0)
    address.setIsDefault(1);
    addressBookService.updateById(address);

    return R.success("修改默认值成功");

2.查询默认地址

从上图分析：addressBook地址，GET方式，default地址
注意数据库addressBook中isDefault的类型，自动生产代码是Boolean类型，需要改为int类型

/**
 * 查询默认地址
 * @param session
 * @return
 */
@GetMapping("/default")
public R<AddressBook> defaultAddress(HttpSession session){
    //查询addressBook中isDefault值  默认 0 否 1是
    LambdaQueryWrapper<AddressBook> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.eq(AddressBook::getUserId, session.getAttribute("user"))
            .eq(AddressBook::getIsDefault, 1);
    AddressBook addressBook = addressBookService.getOne(queryWrapper);
    log.info("addressBook:{}",addressBook);
    if (addressBook == null){
        return R.error("没有默认地址");
    }else {
        return R.success(addressBook);
    }
}
