1.pom引入

        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper</artifactId>
            <version>5.0.2</version>
        </dependency>

2.为sqlsessionfactory添加拦截器

    /**
     * 返回数据库的会话工厂
     *
     * @param ds
     * @return
     * @throws Exception
     */
    @Bean(name = "SqlSessionFactory")
    public SqlSessionFactory sqlSessionFactory(@Qualifier("dbSource") DataSource ds) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(ds);

        //添加分页支持
        Interceptor interceptor = new PageInterceptor();
        Properties properties = new Properties();
        properties.setProperty("helperDialect", "mysql");
        properties.setProperty("offsetAsPageNum", "true");
        properties.setProperty("rowBoundsWithCount", "true");
        properties.setProperty("reasonable", "true");
        properties.setProperty("supportMethodsArguments", "true");
        interceptor.setProperties(properties);
        bean.setPlugins(new Interceptor[]{interceptor});

        return bean.getObject();
    }

3.使用

	@Override
	public PageBean<Map<String, Object>> listMethod(PageReqDto pageReqDto) {
		// TODO Auto-generated method stub
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		PageHelper.startPage(pageReqDto.getPageNum(), pageReqDto.getPageSize());
		list = xxDao.listMethod(pageReqDto);
		PageBean<Map<String, Object>> p = new PageBean<>(list);
		return p;
	}

public class PageReqDto extends BaseReqDto {

	/**
	 * 第几页
	 */
	private Integer pageNum;

	/**
	 * 每页多少行
	 */
	private Integer pageSize;

	/**
	 * 默认第几页
	 */
	public static final Integer PAGENUM_DEFAULT = 1;

	/**
	 * 默认每页显示多少行
	 */
	public static final Integer PAGESIZE_DEFAULT = 10;

	public Integer getPageNum() {
		if (null == pageNum) {
			pageNum = PAGENUM_DEFAULT;
		}
		return pageNum;
	}

	public void setPageNum(Integer pageNum) {

		this.pageNum = pageNum;
	}

	public Integer getPageSize() {
		if (null == pageSize) {
			pageSize = PAGESIZE_DEFAULT;
		}
		return pageSize;
	}

	public void setPageSize(Integer pageSize) {

		this.pageSize = pageSize;

	}
}
