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) <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

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
