1.****
2.匯入jar包
3.根據官方文件,首先寫mybatis-config.xml檔案
xml version="1.0" encoding="utf-8"用來設定資料來源和對映實體的xml檔案,包括為返回值型別起別名,資料來源環境,資料庫廠商(移植性)等等,.,?>
doctype configuration
public "- config 3.0//en"
"">

resource
="conf/jdbc.properties"

4.編寫實體類
publicclass
book
public
void
setid(integer id)
public
string gettitle()
public
void
settitle(string title)
public
string getprice()
public
void
setprice(string price)
public
string getpublishdate()
public
void
setpublishdate(string publishdate)
@override
public
string tostring()
}
xml version="1.0" encoding="utf-8"其中namespace是實體的類路徑,resulttype是返回值型別(全限定類名),databaseid是資料庫廠商id?>
>
<
namespace
>
<
select
id="selectbook"
resulttype
="book"
databaseid
="mysql"
>
select * from book where id = #
select
>
>
6.編寫測試類
public7.執行結果:class
test
finally}}
book [id=1, title=2, price=3, publishdate=2016-11-02 20:44:20.0]
搭建簡單的單個Mybatis框架
最近幾天還是在看框架,都是為了找工作。另外,鄭州的工作是真的不好找。今天來寫乙個搭建單個框架的練習,搭建的是mybatis,主要的原因是自己對於單個框架的原理不太懂,雖然前面的部落格對於ssm框架進行了整合,但是最好還是自己在進行深入的了解。不再廢話了,直接開始。下面就說一說具體的搭建思路。1.複製...
