PageHelper分页是在开发项目的过程中使用过，故记录下

添加依赖：

<dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper-spring-boot-starter</artifactId>
    <version>1.2.3</version>
</dependency>

 

配置文件：

public class ResponseWrapper<T> implements Serializable {
    private String code = "200";
    private String msg;
    private T data;

    public ResponseWrapper(String code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    public ResponseWrapper() {

    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public T getData() {
        return data;
    }

    public ResponseWrapper setData(T data) {
        this.data = data;
        return this;
    }

    public ResponseWrapper error(String code, String msg) {
        this.code = code;
        this.msg = msg;
        return this;
    }
}

 

实体类FetchManagerVo

import lombok.Data;

@Data
public class FetchManagerVo {
    private String id;private int pageNum;
    private int pageSize;
}

 

controller层

/**
 * 取数需求列表(分页)
 */
@PostMapping(value = "/fetchManageList")
public Object getFetchManageList(@RequestBody FetchManagerVo fetchManagerVo){
    return fetchManagerService.getFetchManageList(fetchManagerVo);
}

 

service层

public ResponseWrapper getFetchManageList(FetchManagerVo fetchManagerVo) {
        PageHelper.startPage(fetchManagerVo.getPageNum(),fetchManagerVo.getPageSize());
        List<FetchManager> listData = fetchManageMapper.getFetchManageList(fetchManagerVo);
        return new ResponseWrapper<PageInfo>().setData(new PageInfo(listData));
    }

 

mapper层

List<FetchManager> getFetchManageList(FetchManagerVo fetchManagerVo);

 

xml层

<select id="getFetchManageList" resultType="com.bonc.netax.bean.FetchManager">
        select * from test order by input_time desc
</select>
