数据库列名与实体属性名映射问题

@GreedyStar

oracle默认列名大写，映射为属性名亦为大写，例如：USERNAME
对于以 _ 分隔的列名，映射为属性名时扔包含 _ ，例如：CREATE_TIME

首先感谢作者的慷慨开源哈，然后提几个可能需要调整的点供参考：
1、生成Mapper的时候，columnMap有误：getPropertyName() -> getColumnName();
2、建议Mapper中的所有字段和表都加上反引号``，而不是双引号，防止与mysql关键字冲突；
3、建议默认生成的实体属性类型为包装类型，而不是基本类型，另外，tinyint/smallint/int建议都转换为java.lang.Integer，datetime/time/timestamp建议都转换为java.util.Date类型。

一些建议

1.增加表的注释
2.增加字段的注释
3.增加字段的长度信息

前两者有利于写注释和生成页面，第三条有利于使用校验插件对长度进行检验

发现一个bug啊

ConnectionUtil类
/**
* 获取表结构数据
*
* @param tableName 表名
* @return 包含表结构数据的列表
*/
public List getMetaData(String tableName) throws Exception {
// 获取列信息
List columnInfos = new ArrayList<>();
ResultSet columnResultSet = connection.getMetaData().getColumns(null, getSchema(connection), tableName.toUpperCase(), "%");

这里catalog为null时，数据库存在不同schema有相同的表名和表结构会出现生成实体类里面有重复字段和方法，建议可以把catalog参数加上

报错ftls does not exist

IOUtil.toString()丢失换行符

作者你好，不知道你最近还在不在更新，可能发现了一个bug
IOUtils的toString方法中使用的是BufferedReader的readLine方法，此方法会丢失每行的换行符，会导致yaml解析时报错，具体情况如下：
mapping values are not allowed here
in 'reader', line 1, column 29:
author: dumbcode projectName: test-1projectPath: D:\package ...

我的修复方式是在句末重新append，这样会让此方法改为默认拼接换行
