Maven+Spring+mybatis项目搭建

##倒腾了一个下午，龟速了下载了N多jar后，终于成功跑起##

【前言】使用工具：开发工具使用的是sts(spring tool suite)点击打开链接， JDK 1.7,以及Mybatis generator点击打开链接 主要用来生成model、mapping和dao的，需要自己下载。

【过程】1.建表：建立了一张User表，主要有id,name两个字段

2.修改generator.xml文件，具体如下

<?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><!-- 数据库驱动包位置 --><!-- <classPathEntry location="D:\software\lib\mysql-connector-java-5.1.21.jar" /> --><classPathEntry location="D:\mysql workbench\mysql-connector-5.1.8.jar" /><context id="DB2Tables" targetRuntime="MyBatis3"><commentGenerator><property name="suppressAllComments" value="true" /></commentGenerator><!-- 数据库链接URL、用户名、密码 --><!-- <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl" userId="msa" password="msa">--><jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="123456"> </jdbcConnection><javaTypeResolver><property name="forceBigDecimals" value="false" /></javaTypeResolver><!-- 生成模型的包名和位置 --><javaModelGenerator targetPackage="hd.model" targetProject="D:\maven workspace\src"><property name="enableSubPackages" value="true" /><property name="trimStrings" value="true" /></javaModelGenerator><!-- 生成的映射文件包名和位置 --><sqlMapGenerator targetPackage="hd.mapping" targetProject="D:\maven workspace\src"><property name="enableSubPackages" value="true" /></sqlMapGenerator><!-- 生成DAO的包名和位置 --><javaClientGenerator type="XMLMAPPER" targetPackage="hd.dao" targetProject="D:\maven workspace\src"><property name="enableSubPackages" value="true" /></javaClientGenerator><!-- 要生成那些表(更改tableName和domainObjectName就可以) --><table tableName="test_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" /></context></generatorConfiguration>

3.利用generator.xml自动生成model、mapping和dao,cmd进入generator.xml文件所在的路径上，输入cmd指令:

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

问题1：Generator生成错误：另存为ANSI格式正确生成【没有此问题请忽略】

4.sts工具新建maven project,下一步filter选择webapp【web项目】

下一步填写项目名和包名：

【几个参数】

                     groupId： 相当于这个project的所有者或者机构的一个标识，一般是com.company.xxx这种格式

                    artifactId：  这个project最后所生成的文档(jar、war)的名字，比如对于junit这个开源的project，它的artifactId就是junit

　　             version：版本号。

　　             packaging：包的类型，一般都是jar，也可以是war之类的。如果不填，默认就是jar。

　　             name和url，一个是名称，一个是maven的地址。主要就是上面的几个参数。

建好目录如下：

文件在src/main/java(上面生成语句生成的dao、mapping等)、src/main/resources（配置文件）、/src/test/java（junit测试类）里的结构如下：

Spring.xml配置如下

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd "><!-- 引入属性文件 --><context:property-placeholder location="classpath:config.properties"/><!-- 自动扫描(自动注入) --><context:component-scan base-package="hd.service" /></beans>

Spring-mybatis.xml整合配置如下

jar集合：

5.测试类编写：

import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import hd.model.User;import hd.service.UserService;public class testMybatis {@Testpublic void test1(){ApplicationContext ac=new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});UserService userService=(UserService) ac.getBean("userService");User u=userService.getUserById(1);System.out.println(u.getUsername());}}

6.运行错误

java.lang.IllegalArgumentExceptionorg.springframework.asm.ClassReader.<init>(Unknown Source)org.springframework.asm.ClassReader.<init>(Unknown Source)解决：
一：把jdk版本换成1.7 or 1.7以下
二：使用spring 4.0RELEASE及以上版本

7.成功跑起
