在 foodie-dev-service 模块下的 com.imooc.service 包内创建 AddressService 接口

    1. package com.imooc.service;
    3. import com.imooc.pojo.UserAddress;
    5. import java.util.List;
    7. /**
    8.  * Created by 92578 on 2020/8/22 16:17
    9.  **/
    10. public interface AddressService {
    12.     /**
    13.      * 根据用户 id 查询用户的收获地址列表
    14.      *
    15.      * @param userId
    16.      * @return
    17.      */
    18.     public List<UserAddress> queryAll(String userId);
    19. }

    在 foodie-dev-service 模块下的 com.imooc.service.impl 包内创建 AddressServiceImpl 类，实现 AddressService

    package com.imooc.service.impl;

import com.imooc.mapper.UserAddressMapper;
import com.imooc.pojo.UserAddress;
import com.imooc.service.AddressService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
 * Created by 92578 on 2020/8/22 16:18
 **/
@Service
public class AddressServiceImpl implements AddressService {

    @Autowired
    private UserAddressMapper userAddressMapper;

    /**
     * 根据用户 id 查询用户的收获地址列表
     *
     * @param userId
     * @return
     */
    @Transactional(propagation = Propagation.SUPPORTS)
    @Override
    public List<UserAddress> queryAll(String userId) {
        UserAddress ua = new UserAddress();
        ua.setUserId(userId);

        return userAddressMapper.select(ua);
    }
}

    在 foodie-dev-api 模块下的 com.imooc.controller 创建 AddressController 类，新增 list 方法

    package com.imooc.controller;

import com.imooc.pojo.UserAddress;
import com.imooc.service.AddressService;
import com.imooc.utils.IMOOCJSONResult;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * @author 92578
 * @since 1.0
 */
@Api(value = "地址相关",tags = {"地址相关的 api 接口"})
@RequestMapping("address")
@RestController
public class AddressController {

    @Autowired
    private AddressService addressService;

    @ApiOperation(value = "根据用户 id 查询收货地址列表", notes = "根据用户 id 查询收货地址列表", httpMethod = "POST")
    @PostMapping("/list")
    public IMOOCJSONResult list(
            @RequestParam String userId) {
        if (StringUtils.isBlank(userId)) {
            return IMOOCJSONResult.errorMsg("");
        }

        List<UserAddress> list = addressService.queryAll(userId);
        return IMOOCJSONResult.ok(list);
    }
}

    启动项目，打开浏览器，访问 http://localhost:8088/doc.html
    找到“根据用户 id 查询收货地址列表”接口，输入 userId 值“1908189H7TNWDTXP”进行调试，返回相应地址内容
