mybatis 中 Example 的使用 ：条件查询、排序、分页

   import tk.mybatis.mapper.entity.Example;
   import com.github.pagehelper.PageHelper;

...

    @Override
    public List<RepaymentPlan> listRepaymentPlan(Integer start) {

    
        Example example = new Example(RepaymentPlan.class);
        // 排序
        example.orderBy("id");
        // 条件查询
        example.createCriteria()
                .andNotEqualTo("repayStatus", 3)
                .andLessThanOrEqualTo("shouldRepayDate", new Date());
        // 分页
        PageHelper.startPage(start, 20); // 每次查询20条

        return repaymentPlanMapper.selectByExample(example);
    }

PageHelper.startPage(第几页, 20,false); // 每次查询20条

 public List<RepayPlan> listRepayPlan(int start) {
        // 查询所有未还款结清且应还日期小于当前时间的账单
        Example example = new Example(RepayPlan.class);
        example.orderBy("id "); // 按id排序
        example.createCriteria()
                .andNotEqualTo("repayStatus", 3)
                .andLessThanOrEqualTo("shouldRepayDate", new Date());
        RowBounds rowBounds = new RowBounds(start, 20); //　每次查询20条
        return epaymentPlanMapper.selectByExampleAndRowBounds(example,rowBounds);
    }
