maven+spring+spring+myBatis整合
目录：
-
- 一 开发环境
- 二 开发步骤
- 三 xml AND pom
- 四 编码
- 测试
一 、开发环境
1. jdk 1.8
2. eclipse neon2
2. Maven 3.3.9
3. MySQL 5.5.49
4. spring 、 springmvc 4.2.4RELEASE
5. myBatis 3.2.8 （mybatis-spring 1.2.2）
二 、开发步骤
1.创建 maven 的 web 项目，可以建立一个web项目，也可以创建一个父工程
2.创建 properties 配置文件
3.mybatis + spring + springmvc 配置文件 (这里指定包的时候就可以创建出来)
4.配置 web.xml
5.编码
6.测试
三 、xml AND pom
1. SqlMapConfig.xml(给个表头什么都不用写 - 这里我们在 src/main/resources 创建 mybatis 文件夹)
<configuration>configuration>2.applicationContext_dao.xml(持久层，src/main/resources 创建 spring 文件夹)

project>这里使用逆向工程生成mapper ， pojo
我使用的逆向工程下载链接 ：逆向工程
这里mapper.xml 的配置文件 ，我是放在 src/main/resources 下面创建的跟 src/main/java 同样的层级目录放置
四 、 编码
既然你看到了这里，想必你已经了解过 maven ， spring ， pringmvc ，mybatis , 整合重点就是配置文件
1. Controller
@Controller
@RequestMapping("/XXX") //注解指定请求的url
public class AaaController {
@Autowired
private AbbService abbService;
//返回 ModelAndView 方式
@RequestMapping("/yyy.action")//注解指定请求的url
public String xxx(Model model,Pojo pojo) {
//调用service代码处理
//参数回显
model.addAttribute("回显参数","service请求回来的参数");
return "页面名字(没有.jsp)";
}
}2. Service
public interface AbbService {//方法}
@Service
@Transactional
public class AbbServiceImpl implements AbbService{
@Autowired
private AbcDao abcDao;
//方法逻辑处理
}3.Dao
public interface AbcDao{
//方法 - 这里注意方法名和mapper.xml id 一致！
}测试
1. 单独测试
您可以在serivce 自己模拟数据 ， 用 @Test 测试您的持久层
2. 整合测试
想必一个简单的dmeo 你已经写出来了。你可以把项目跑起来测试
安装工程：右键工程——Run AS——Maven install。
运行：右键工程——Run AS——build.. Goals 输入 clean tomcat7:run //这里是配置一起启动命令，后期可能还需要运行，配置一个clean 是清除
