HAP_REST使用_综合练习

业务需求：

综合练习：
实现通过REST接口来对供应商的增删改查功能
利用框架自动生成开发供应商简单维护界面
开发接口：对供应商批量或者单个新增
开发接口：对供应商更新
开发接口：查询供应商
开发接口：删除供应商

实现效果图：

步骤一：数据表准备：

CREATE TABLE `wht_ora_20796_vendor` (
  `VENDOR_ID` int(128) NOT NULL AUTO_INCREMENT,
  `VENDOE_NUMBER` varchar(128) DEFAULT NULL COMMENT '供应商编码',
  `VENDOR_NAME` varchar(128) DEFAULT NULL,
  `VENDOR_TYPE_CODE` varchar(128) DEFAULT NULL COMMENT '供应商类型',
  `ADDRESS` varchar(128) DEFAULT NULL COMMENT '供应商地址',
  `TEL_NUMBER` varchar(128) DEFAULT NULL,
  `BEGIN_DATE` date DEFAULT NULL,
  `END_DATE` date DEFAULT NULL,
  `OBJECT_VERSION_NUMBER` int(11) DEFAULT '1' COMMENT '版本号',
  `CREATION_DATE` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `CREATED_BY` int(11) NOT NULL DEFAULT '-1',
  `LAST_UPDATED_BY` int(11) NOT NULL DEFAULT '-1',
  `LAST_UPDATE_DATE` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `LAST_UPDATE_LOGIN` int(11) DEFAULT NULL,
  `PROGRAM_ID` int(11) DEFAULT NULL,
  `REQUEST_ID` int(11) DEFAULT NULL,
  `ATTRIBUTE_CATEGORY` varchar(30) DEFAULT NULL,
  `ATTRIBUTE1` varchar(240) DEFAULT NULL,
  `ATTRIBUTE2` varchar(240) DEFAULT NULL,
  `ATTRIBUTE3` varchar(240) DEFAULT NULL,
  `ATTRIBUTE4` varchar(240) DEFAULT NULL,
  `ATTRIBUTE5` varchar(240) DEFAULT NULL,
  `ATTRIBUTE6` varchar(240) DEFAULT NULL,
  `ATTRIBUTE7` varchar(240) DEFAULT NULL,
  `ATTRIBUTE8` varchar(240) DEFAULT NULL,
  `ATTRIBUTE9` varchar(240) DEFAULT NULL,
  `ATTRIBUTE10` varchar(240) DEFAULT NULL,
  `ATTRIBUTE11` varchar(240) DEFAULT NULL,
  `ATTRIBUTE12` varchar(240) DEFAULT NULL,
  `ATTRIBUTE13` varchar(240) DEFAULT NULL,
  `ATTRIBUTE14` varchar(240) DEFAULT NULL,
  `ATTRIBUTE15` varchar(240) DEFAULT NULL,
  PRIMARY KEY (`VENDOR_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

步骤二：自动生成代码

步骤三：去到Ora20796VendorMapper.xml写sql语句

    <!--查询经销商-->
    <select id="selectVendorRest" resultMap="BaseResultMap" parameterType="wht.ora20796.dto.Ora20796Vendor">
        SELECT
        VENDOR_ID,
        VENDOE_NUMBER,
        VENDOR_NAME,
        VENDOR_TYPE_CODE,
        ADDRESS,
        TEL_NUMBER,
        BEGIN_DATE,
        END_DATE
        FROM wht_ora_20796_vendor
    </select>
    <!--保存经销商-->
    <insert id="saveVendorRest" parameterType="wht.ora20796.dto.Ora20796Vendor">
        insert into wht_ora_20796_vendor (VENDOE_NUMBER,VENDOR_NAME)value(#{vendoeNumber},#{vendoeNumber})
    </insert>
    <!--更改经销商-->
    <update id="updateVendorRest" parameterType="wht.ora20796.dto.Ora20796Vendor">
        update wht_ora_20796_vendor set VENDOE_NUMBER=#{vendoeNumber} where VENDOR_ID=#{vendorId}
    </update>
    <!--删除经销商-->
    <delete id="deleteVendorRest" parameterType="wht.ora20796.dto.Ora20796Vendor">
        delete from wht_ora_20796_vendor where VENDOR_ID=#{vendorId}
    </delete>

步骤四：去到Ora20796VendorMapper.java
注意！！！方法名要和Ora20796VendorMapper.xml里的id一样

package wht.ora20796.mapper;

import com.hand.hap.mybatis.common.Mapper;
import wht.ora20796.dto.Ora20796Vendor;

import java.util.List;

public interface Ora20796VendorMapper extends Mapper<Ora20796Vendor> {

    /**
     * 查询经销商
     * @param dto
     * @return
     */
    List<Ora20796Vendor> selectVendorRest(Ora20796Vendor dto);
    /**
     * rest保存经销商
     *
     * @param criteria
     */
    void saveVendorRest(Ora20796Vendor criteria);

    /**
     * 更新经销商
     *
     * @param criteria
     */
    void updateVendorRest(Ora20796Vendor criteria);

    /**
     * 删除经销商
     * @param criteria
     */
    void deleteVendorRest(Ora20796Vendor criteria);
}

步骤五：去到控制类Ora20796VendorController.java写我们的rest

   @Autowired
    private IOra20796VendorService service;
    @Autowired
    private Ora20796VendorMapper mapper;

    /*--------自定义rest测试-----开始--------*/
    //rest查询
    @RequestMapping(
            value = {"/api/public/wht/ora20796/vendor/rest/query/v1"},
            method = {RequestMethod.GET, RequestMethod.POST}
    )
    @ResponseBody
    @HapInbound(apiName = "wht.ora20796.vendor.rest.query.v1")
    public ResponseData queryVendor(Ora20796Vendor dto, @RequestParam(defaultValue = DEFAULT_PAGE) int page,
                                  @RequestParam(defaultValue = DEFAULT_PAGE_SIZE) int pageSize, HttpServletRequest request) {
        IRequest requestContext = createRequestContext(request);
        return new ResponseData(mapper.selectVendorRest(dto));
    }
    //rest添加
    @RequestMapping(
            value = {"/api/public/wht/ora20796/vendor/rest/add/v1"},
            method = {RequestMethod.GET, RequestMethod.POST, RequestMethod.PUT}
    )
    @ResponseBody
    @HapInbound(apiName = "wht.ora20796.vendor.rest.add.v1")
    public ResponseData saveVendor(@RequestBody List<Ora20796Vendor> dto, BindingResult result, HttpServletRequest request) {
        for (Ora20796Vendor ora20796Vendor : dto) {
            mapper.saveVendorRest(ora20796Vendor);
        }
        return new ResponseData();
    }

    //更新经销商
    @RequestMapping(
            value = {"/api/public/wht/ora20796/vendor/rest/update/v1"},
            method = {RequestMethod.GET, RequestMethod.POST, RequestMethod.PUT}
    )
    @ResponseBody
    @HapInbound(apiName = "wht.ora20796.vendor.rest.update.v1")
    public ResponseData updateVendor(@RequestBody List<Ora20796Vendor> dto, BindingResult result, HttpServletRequest request) {
        for (Ora20796Vendor ora20796Vendor : dto) {
            mapper.updateVendorRest(ora20796Vendor);
        }
        return new ResponseData();
    }

    //删除经销商
    @RequestMapping(
            value = {"/api/public/wht/ora20796/vendor/rest/delete/v1"},
            method = {RequestMethod.GET, RequestMethod.POST, RequestMethod.DELETE}
    )
    @ResponseBody
    @HapInbound(apiName = "wht.ora20796.vendor.rest.delete.v1")
    public ResponseData deleteVendor(@RequestBody List<Ora20796Vendor> dto, BindingResult result, HttpServletRequest request) {
        for (Ora20796Vendor ora20796Vendor : dto) {
            mapper.deleteVendorRest(ora20796Vendor);
        }
        return new ResponseData();
    }

到这里就结束了，重启，去到postman测试测试吧
