插件PageHelper实现分页查询

    一,需求:

CommonQuery--PyQueryBean

PyQueryBean:鹏飞历史记录查询,以往哪些人对征信进行了查询。
CommonQuery:查询条件:根据查询人(umName)、被查询人姓名(name)、身份证号(documentNo)、手机号(phone)、查询日期(queryDate)
二,配置相关:
1,mybatis-config.xml

<!-- 配置分页插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->
            <property name="helperDialect" value="mysql"/>
        </plugin>
    </plugins>
复制代码
2,pom依赖
 <!-- mybatis分页 -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.1.2</version>
        </dependency>
三,代码
Controller
/**
     * @param request, pyQueryBean
     * @return com.pingan.credit.model.ResponseResult<java.util.List<com.pingan.credit.model.py.PyQueryBean>>
     * @Description: 历史记录查询
     * @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;
    }
接口响应类
public class ResponseResult<T> extends BasePojo {
    /**成功标识符 **/
    private boolean ret;
    /** 异常信息**/
    private String errorMsg;
    /** 返回数据类型 **/
    private T data;
    /** 异常码 **/
    private String errorCode;
    /** 请求ID**/
    private String refID;
    /** 时间戳 **/
    private String timestamp;
--响应结果类
public
class PyQueryBean extends BaseQuery implements Serializable { private transient int id; /**查询者姓名,不允许为空**/ private String name; //被查询者证件号码,不允许为空 private String documentNo; //被查询者手机号码,反欺诈的报告不允许为空 深圳个人征信可以为空 private String phone; //查询原因ID,只能传本单位允许的查询原因 101 private String queryReasonID; //96040 反欺诈 90008 深圳个人信用 private String subreportIDs; //引用ID,查询者提交的用于识别本次查询的流水号,系统返回结果中会原样包含该流水号。可以为空。 private String refID; private String umName; //证件类型 private String documentType; //报告 private String docId; //查询日期 private String queryDate; //查询类型 @JSONField(serialize = false ) private Integer queryType; private String imageId; //是否直连 1:直连 private Integer queryFromPy;
