SpringMVC整合mybatis實(shí)例代碼

更新時(shí)間：2016年05月11日 13:49:16 作者：小禾點(diǎn)點(diǎn)

MyBatis 的前身就是 iBatis 。是一個(gè)數(shù)據(jù)持久層(ORM)框架。下面通過(guò)本文給大家介紹SpringMVC整合mybatis實(shí)例代碼，感興趣的朋友一起學(xué)習(xí)吧

MyBatis 本是apache的一個(gè)開(kāi)源項(xiàng)目iBatis, 2010年這個(gè)項(xiàng)目由apache software foundation 遷移到了google code，并且改名為MyBatis 。

一、逆向工程生成基礎(chǔ)信息

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<context id="testTables" targetRuntime="MyBatis3">
<commentGenerator>
<!-- 是否去除自動(dòng)生成的注釋 true：是 ： false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!--數(shù)據(jù)庫(kù)連接的信息：驅(qū)動(dòng)類、連接地址、用戶名、密碼 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3307/mybatis" userId="root"
password="jalja">
</jdbcConnection>
<!-- 默認(rèn)false，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer，為 true時(shí)把JDBC DECIMAL 和 
NUMERIC 類型解析為java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- targetProject:生成PO類的位置 -->
<javaModelGenerator targetPackage="com.jalja.springmvc_mybatis.model.pojo"
targetProject=".\src">
<!-- enableSubPackages:是否讓schema作為包的后綴 -->
<property name="enableSubPackages" value="false" />
<!-- 從數(shù)據(jù)庫(kù)返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- targetProject:mapper映射文件生成的位置 -->
<sqlMapGenerator targetPackage="com.jalja.springmvc_mybatis.mapper" 
targetProject=".\src">

<property name="enableSubPackages" value="false" />
</sqlMapGenerator>
<!-- targetPackage：mapper接口生成的位置 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.jalja.springmvc_mybatis.mapper" 
targetProject=".\src">
<!-- enableSubPackages:是否讓schema作為包的后綴 -->
<property name="enableSubPackages" value="false" />
</javaClientGenerator>
<!-- 指定數(shù)據(jù)庫(kù)表 -->
<table tableName="items"></table>
<table tableName="orders"></table>
<table tableName="orderdetail"></table>
<table tableName="user"></table>
</context>
</generatorConfiguration> 
public static void main(String[] arhs) throws Exception{
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("src.main.resources/generator.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
myBatisGenerator.generate(null);
}

二、springMVC與Mybatis整合各個(gè)配置文件

1.項(xiàng)目結(jié)構(gòu)

2、各個(gè)文件的核心代碼
