插件PageHelper實現分頁查詢

    一，需求：

CommonQuery--PyQueryBean

PyQueryBean：鵬飛歷史記錄查詢，以往哪些人對徵信進行了查詢。
CommonQuery：查詢條件：根據查詢人(umName)、被查詢人姓名(name)、身份證號(documentNo)、手機號(phone)、查詢日期(queryDate)
二，配置相關：
1，mybatis-config.xml

<!-- 配置分頁插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <!-- 設置數據庫類型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六種數據庫-->
            <property name="helperDialect" value="mysql"/>
        </plugin>
    </plugins>
複製代碼

2，pom依賴

 <!-- mybatis分頁 -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.1.2</version>
        </dependency>

三，代碼
Controller

/**
     * @param request, pyQueryBean
     * @return com.pingan.credit.model.ResponseResult<java.util.List<com.pingan.credit.model.py.PyQueryBean>>
     * @Description: 歷史記錄查詢
     * @date 2017/11/23 17:00
     */
    @RequestMapping(path = "/queryPyHistoryRecord", method = {RequestMethod.GET, RequestMethod.POST})
    @ResponseBody
    public ResponseResult<BasePageInfo<PyQueryBean>> queryPyHistoryRecord(HttpServletRequest request, CommonQuery commonQuery) {
        ResponseResult<BasePageInfo<PyQueryBean>> responseResult = new ResponseResult<>();
        try {
            BasePageInfo<PyQueryBean> pageInfo = pyQueryService.queryHistoryRecord(commonQuery);
            responseResult.setData(pageInfo);
            responseResult.setRet(SUCCESS);
            responseResult.setRefID(commonQuery.getRefID());
            responseResult.setTimestamp(DateUtil.getTimeStamp().toString());
        } catch (CreditException e) {
            responseResult.setErrorCode(e.getErrorCode());
            responseResult.setRet(SUCCESS);
            responseResult.setErrorMsg(e.getMessage());
        } catch (Exception e) {
            responseResult.setErrorCode(PyCreditServiceErrorEnum.SYSTEM_ERROR.getCode());
            responseResult.setRet(FAILED);
            responseResult.setErrorMsg(PyCreditServiceErrorEnum.SYSTEM_ERROR.getMsg());
        }
        return responseResult;
    }

接口響應類

public class ResponseResult<T> extends BasePojo {
    /**成功標識符 **/
    private boolean ret;
    /** 異常信息**/
    private String errorMsg;
    /** 返回數據類型 **/
    private T data;
    /** 異常碼 **/
    private String errorCode;
    /** 請求ID**/
    private String refID;
    /** 時間戳 **/
    private String timestamp;

--響應結果類
public class PyQueryBean extends BaseQuery implements Serializable {

    private transient int id;
    /**查詢者姓名，不容許爲空**/
    private String name;

    //被查詢者證件號碼，不容許爲空
    private String documentNo;

    //被查詢者手機號碼，反欺詐的報告不容許爲空 深圳我的徵信能夠爲空
    private String phone;
    //查詢緣由ID，只能傳本單位容許的查詢緣由 101
    private String queryReasonID;
    //96040 反欺詐 90008 深圳我的信用
    private String subreportIDs;

    //引用ID，查詢者提交的用於識別本次查詢的流水號，系統返回結果中會原樣包含該流水號。能夠爲空。
    private String refID;

    private String umName;
    //證件類型
    private String documentType;
    //報告
    private String docId;
    //查詢日期
    private String queryDate;
    //查詢類型
    @JSONField(serialize = false )
    private Integer queryType;

    private String imageId;

    //是否直連 1:直連
    private Integer queryFromPy;
