解决mybatis-plus 3.1.1版本使用lambda表达式查询报错

最近项目中使用了mybatis-plus 3.1.1版本，发现使用lambda表达式方式的条件构造器，执行时会报错；但是我用单元测试却通过，真是一个大坑啊。经过在网上一顿猛查，发现压根就是没有找到类似的问题，所以今天就记录一下这个大坑。

测试代码：

	@Override
    public User getByUsername(String username) {
        return super.getOne(new QueryWrapper().lambda().eq(User::getUsername, username));
    }

先看看报错如下：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error evaluating expression 'ew.sqlSegment != null and ew.sqlSegment != '' and ew.nonEmptyOfWhere'. Cause: org.apache.ibatis.ognl.OgnlException: sqlSegment [com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: Your property named "username" cannot find the corresponding database column name!]
