### MyBatis example使用报错：There is no getter for property named ‘distinct’ in ‘class com.ld.model.TGeoTestExample$Criteria’ ###

TGeoTestExample.Criteria example = new TGeoTestExample().createCriteria();
            example.andNAMEEqualTo("P1");
            List<TGeoTest> list1 = mapper.selectByExample(example);

参数对象使用错误，selectByExample中应该传入TGeoTestExample参数对象，这里传入了TGeoTestExample.Criteria对象，所以报错了，

修改代码：

TGeoTestExample example = new TGeoTestExample();
            example.createCriteria().andNAMEEqualTo("P1");
            List<TGeoTest> list1 = mapper.selectByExample(example);

运行成功：

[TGeoTest{ id=1, name=P1, shape=[Ljava.math.BigDecimal;@249f3966}]
    [TGeoTest{ id=1, name=P1, shape=[Ljava.math.BigDecimal;@37470dd7}]
