springMVC,spring,mybatis全注解搭建框架--第一步,让框架跑起来
自己从事java开发工作也有一年多了,自己却没有亲手搭建一个完整的框架。于是今天自己动手搭建一个,过程中遇到一些问题,倒腾了大半天终于搞定了。
现在给大家分享一下过程,自己也记录下来,以后学习参考使用。
我采用全注解的方式去搭建springMVC,spring,mybatis框架,同时自己也可以去配置xml,但是主要还是通过注解的方式来实现。参考的网上其它大神分享的方法,多多少少有些地方写的不清楚,也并不是完全通过注解去实现的。
springboot可以真正说是零配置吧,后面我将给大家演示springboot搭建的过程。
1.先介绍一下我使用的开发环境:
idea,jdk1.7,tomcat7.0,操作系统就不用介绍了(winddos10)。
2.使用框架:
2.1:前台我使用freemarker模板,通常咋们说的ftl文件。
2.2:后台我使用springMVC,spring,mybatis。
2.3:数据库我使用mysql,也可以使用orcl,更换一下配置就OK。
3.管理工具:
maven
在开始贴出源码之前,我先贴出idea在创建maven项目以及在配置tomcat需要注意的几个问题,我在部署项目的时候,idea提示项目部署成功但是就是没有启动tomcat发布项目,搞了半天,真滴蛋疼。
1.我的架构目录,设置source和resource不要忘记了。
2.最关键的地方。
2.1:web Module Deployment Descriptor 后面的xml文件,是你项目的入口。一般是web.xml文件,检查路径是否正确。
2.2:web Resource Directory 是对应你webapp下部署到tomcat的文件。
2.3:source root 是你的源文件,检查是否正确。
3.有一个更重要的设置,大家务必要检查一下,不然项目就无法启动,也不报什么错误。就是下面截图的几个参数设置,要和你本地的jdk版本一致。
3.2:有个更更更重要的地方一定要检查一下,把你这些jar包都put到lib下面。
4.其他的配置我就不说了,都一样。如果大家要这前面的过程,在评论说出来,我整理出一个word文档分享给大家。
下面我就直接贴出源码了。
pom.xml .===这个地方我没有把版本组件提取出来,不过不影响使用,里面有些其他的jar在后面会使用其他的功能。

6.下面来说src下的目录结构,如下图
7.application.xml 文件

9.mybatis.xml文件,mybatis和spring整合之后配置文件很简单了。
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 6 <configuration> 7 <settings> 8 <!--配置实体类与数据库字段驼峰命名--> 9 <setting name="mapUnderscoreToCamelCase" value="true"/> 10 </settings> 11 <!-- 设置别名 --> 12 <typeAliases> 13 <!-- 2. 指定扫描包,会把包内所有的类都设置别名,别名的名称就是类名,大小写不敏感 --> 14 <package name="com.panpan.entity" /> 15 </typeAliases> 16 17 </configuration>

12.jdbc.properties数据库连接配置文件
1 jdbc.driver=com.mysql.jdbc.Driver 2 jdbc.url=jdbc:mysql://localhost:3306/school_bl 3 jdbc.username=root 4 jdbc.password=root 5 jdbc.maxActive=30 6 jdbc.maxIdle=10 7 jdbc.initialSize=5
13.实体类User.java这里我采用了lombok提供的@Data注解,省去了getter和setter方法。pom.xml中引入lombok依赖,如果使用idea,那在安装一下lombok的插件就可以使用啦。
1 package com.panpan.entity; 2 3 import lombok.Data; 4 5 import javax.persistence.Id; 6 import javax.persistence.Table; 7 8 /** 9 * Created by panpan on 2018/2/27. 10 */ 11 @Table(name = "user") 12 @Data 13 public class User { 14 @Id 15 private String id; 16 private String loginName; 17 private String loginPassword; 18 }
14.user接口定义,这个也不需要实现类。
1 package com.panpan.service.inter; 2 3 import com.panpan.entity.User; 4 import org.apache.ibatis.annotations.Select; 5 import org.springframework.stereotype.Service; 6 7 import java.util.List; 8 9 /** 10 * Created by panpan on 2018/3/2. 11 */ 12 @Service 13 public interface UserInter { 14 @Select("select * from school_bl.user t where t.id=#{id}") 15 public User findById(String id); 16 17 @Select("select * from school_bl.user") 18 public List<User> findAll(); 19 }
15.controller控制器层
1 package com.panpan.webController; 2 3 import com.panpan.entity.User; 4 import com.panpan.service.inter.UserInter; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.stereotype.Controller; 7 import org.springframework.web.bind.annotation.RequestMapping; 8 import org.springframework.web.bind.annotation.ResponseBody; 9 import org.springframework.web.servlet.ModelAndView; 10 11 import java.util.List; 12 13 /** 14 * Created by panpan on 2018/2/18. 15 */ 16 @Controller 17 @RequestMapping("sys") 18 public class Login { 19 @Autowired 20 UserInter userInter; 21 ModelAndView modelAndView = new ModelAndView(); 22 23 @RequestMapping("login") 24 @ResponseBody 25 public ModelAndView getLogin() { 26 27 User user = userInter.findById("1"); 28 modelAndView.addObject("user", user); 29 modelAndView.setViewName("login/login"); 30 return modelAndView; 31 } 32 33 @RequestMapping("getAllUsers") 34 @ResponseBody 35 public ModelAndView getAllUsers() { 36 List<User> users = userInter.findAll(); 37 modelAndView.addObject("users", users); 38 modelAndView.setViewName("test"); 39 return modelAndView; 40 } 41 }
16.把以上的都写完之后,咱们来看看web-app下面的目录结构,这些就是页面啦,先测试一下,让整个框架跑起来。
17.test.ftl页面
1 <h2> 2 <#if users??> 3 <#list users as user > 4 <td>${user.id!}</td> 5 <td> ${user.loginName!}</td> 6 <td>${user.loginPassword!}</td> 7 </br> 8 </#list> 9 </#if> 10 </h2>
18.login.ftl页面
1 <h2> 2 ${user.id!} 3 ${user.loginName!} 4 ${user.loginPassword!} 5 </h2>
19.mysql数据库结构
20.然后就可以把程序跑起来了,看的以下结果。
ok啦,框架能正常跑起来了,后面第二次内容将会添加更新,插入和删除数据,包括前台获取参数,分页查询。
感谢各位大牛们能看到结尾,如果有问题的地方可以在评论提出来,大家一起交流学习,您们的点评就是我学习的动力!
如果需要源码的话,也留个言哦,我把gtiHup上的地址给大家。
