springMVC+mybatis框架搭建
在上一遍博客中以及讲诉了新建maven项目的流程，现在紧跟上一遍文章，接着搭建spring项目
首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？
（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）
1. 工程目录结构整理清楚
在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean),
cn.springmvc.dao（存放spring与mybatis连接接口）,
cn.springmvc.service（service接口）,
cn.springmvc.service.impl（service接口的实现），
cn.springmvc.controller（存放控制层controller）
在src/main/resource文件夹中，新建包conf（存放配置文件），
mapper（mybatis的mapper文件）
在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)
在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）
这样项目结构基本完成了
2. 引入依赖包
打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）
查找依赖结构有个不错的网站， 只要输入包名即可查找引来关系
pom.xml(包依赖)

3. 配置数据库连接属性
conf/ jdbc.properties（jdbc配置文件)
| 1 2 3 4 | jdbc_driverClassName=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql: //localhost:3306/mydays?useUnicode=true&characterEncoding=utf-8 jdbc_username=root jdbc_password=root |
4. 配置spring配置文件
conf/spring.xml(spring配置文件的扫描)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <? xml version = "1.0" encoding = "UTF-8" ?> < beans xmlns = "http://www.springframework.org/schema/beans" xmlns:context = "http://www.springframework.org/schema/context" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 引入jdbc配置文件 --> < context:property-placeholder location = "classpath:conf/jdbc.properties" /> <!-- 扫描文件（自动将servicec层注入） --> < context:component-scan base-package = "cn.springmvc.service" /> </ beans > |
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 | <? 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:p = "http://www.springframework.org/schema/p" xmlns:context = "http://www.springframework.org/schema/context" xmlns:aop = "http://www.springframework.org/schema/aop" xmlns:tx = "http://www.springframework.org/schema/tx" xmlns:util = "http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"> < bean id = "dataSource" class = "com.alibaba.druid.pool.DruidDataSource" init-method = "init" destroy-method = "close" > < property name = "driverClassName" > < value >${jdbc_driverClassName}</ value > </ property > < property name = "url" > < value >${jdbc_url}</ value > </ property > < property name = "username" > < value >${jdbc_username}</ value > </ property > < property name = "password" > < value >${jdbc_password}</ value > </ property > <!-- 连接池最大使用连接数 --> < property name = "maxActive" > < value >20</ value > </ property > <!-- 初始化连接大小 --> < property name = "initialSize" > < value >1</ value > </ property > <!-- 获取连接最大等待时间 --> < property name = "maxWait" > < value >60000</ value > </ property > <!-- 连接池最大空闲 --> < property name = "maxIdle" > < value >20</ value > </ property > <!-- 连接池最小空闲 --> < property name = "minIdle" > < value >3</ value > </ property > <!-- 自动清除无用连接 --> < property name = "removeAbandoned" > < value >true</ value > </ property > <!-- 清除无用连接的等待时间 --> < property name = "removeAbandonedTimeout" > < value >180</ value > </ property > <!-- 连接属性 --> < property name = "connectionProperties" > < value >clientEncoding=UTF-8</ value > </ property > </ bean > <!-- mybatis文件配置，扫描所有mapper文件 --> < bean id = "sqlSessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref = "dataSource" p:configLocation = "classpath:conf/mybatis-config.xml" p:mapperLocations = "classpath:mapper/*.xml" /> <!-- configLocation为mybatis属性 mapperLocations为所有mapper--> <!-- spring与mybatis整合配置，扫描所有dao --> < bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage = "cn.springmvc.dao" p:sqlSessionFactoryBeanName = "sqlSessionFactory" /> <!-- 对数据源进行事务管理 --> < bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref = "dataSource" /> </ beans > |
5. java代码编写（model，dao，service层代码）
cn.springmvc.model/User.java(用户基本信息)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | package cn.springmvc.model; /** * 用户表 */ public class User { private int id; private int state; private String nickname; public int getId() { return id; } public void setId( int id) { this .id = id; } public int getState() { return state; } public void setState( int state) { this .state = state; } public String getNickname() { return nickname; } public void setNickname(String nickname) { this .nickname = nickname; } } |
cn.springmvc.dao/UserDAO.java(dao操作接口)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | package cn.springmvc.dao; import cn.springmvc.model.User; public interface UserDAO { /** * 添加新用户 * @param user * @return */ public int insertUser(User user); } |
cn.springmvc.service/UserService.java(service层接口)
| 1 2 3 4 5 6 7 8 9 | package cn.springmvc.service; import cn.springmvc.model.User; public interface UserService { public int insertUser(User user); } |
cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | package cn.springmvc.service.impl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import cn.springmvc.dao.UserDAO; import cn.springmvc.model.User; import cn.springmvc.service.UserService; @Service public class UserServiceImpl implements UserService{ @Autowired private UserDAO userDAO; @Override public int insertUser(User user) { // TODO Auto-generated method stub return userDAO.insertUser(user); } } |
6. mybatis配置
conf/mybatis-config.xml(mybatis配置的基本文件)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | <? xml version = "1.0" encoding = "UTF-8" ?> <! DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> < configuration > <!-- 命名空间 --> < typeAliases > < typeAlias alias = "User" type = "cn.springmvc.model.User" /> </ typeAliases > <!-- 映射map --> < mappers > </ mappers > </ configuration > |
mapper/UserMapper.xml(mybatis的实现)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <? xml version = "1.0" encoding = "UTF-8" ?> <! DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> < mapper namespace = "cn.springmvc.dao.UserDAO" > < insert id = "insertUser" parameterType = "User" keyProperty = "id" > insert into days_user( state, nickname) values ( #{state}, #{nickname}) </ insert > </ mapper > |
这样就完成了基本插入用户的功能！
7. junit测试插入功能
cn.springmvc.test/UserTest.java(用户测试模块)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | package cn.springmvc.test; import org.junit.Before; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import cn.springmvc.model.User; import cn.springmvc.service.UserService; public class UserTest { private UserService userService; @Before public void before(){ @SuppressWarnings ( "resource" ) ApplicationContext context = new ClassPathXmlApplicationContext( new String[]{ "classpath:conf/spring.xml" , "classpath:conf/spring-mybatis.xml" }); userService = (UserService) context.getBean( "userServiceImpl" ); } @Test public void addUser(){ User user = new User(); user.setNickname( "你好" ); user.setState( 2 ); System.out.println(userService.insertUser(user)); } } |
测试结果如图：
即完成插入功能！
8. springMVC模块搭建
