SpringMvc+Spring+MyBatis+Maven

使用Maven构建项目

1) 创建一个Maven的war工程

2) 在webapp/WEB-INF下创建一个web.xml文件

1 <?xml version="1.0" encoding="UTF-8"?>
2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3     xmlns="http://java.sun.com/xml/ns/javaee"
4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
5     id="WebApp_ID" version="2.5">
6 </web-app>

3) Maven引入需要的jar包地址:http://mvnrepository.com/ 可以在这里搜索需要的jar引入配置到底是使用远程仓库还是本地仓库随读者的意愿。

　　引入jar的配置代码如下:

  1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4)web.xml的配置

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns="http://java.sun.com/xml/ns/javaee"
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
 5     id="WebApp_ID" version="2.5">
 6     
 7     <!-- 1.启动Spring的容器,需要配置ContextLoaderListener -->
 8     <context-param>
 9         <param-name>contextConfigLocation</param-name>
10         <param-value>classpath:applicationContext.xml</param-value>
11     </context-param>
12     
13     <!-- 2.配置ContextLoaderListener -->
14     <listener>
15         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
16     </listener>
17     
18     <!-- 3.SpringMvc的前端控制器，拦截所有请求 -->
19     <servlet>
20         <servlet-name>dispatcherServlet</servlet-name>
21         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
22         <load-on-startup>1</load-on-startup>
23     </servlet>
24     <servlet-mapping>
25         <servlet-name>dispatcherServlet</servlet-name>
26         <url-pattern>*.do</url-pattern>
27     </servlet-mapping>
28     
29     <!-- 4.字符编码的过滤器，放在所有的过滤器之前 -->
30     <filter>
31         <filter-name>CharacterEncodingFilter</filter-name>
32         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
33         <init-param>
34             <param-name>encoding</param-name>
35             <param-value>utf-8</param-value>
36         </init-param>
37         <init-param>
38             <param-name>forceRequestEncoding</param-name>
39             <param-value>true</param-value>
40         </init-param>
41         <init-param>
42             <param-name>forceResponseEncoding</param-name>
43             <param-value>true</param-value>
44         </init-param>
45     </filter>
46     <filter-mapping>
47         <filter-name>CharacterEncodingFilter</filter-name>
48         <url-pattern>/*</url-pattern>
49     </filter-mapping>
50     
51 </web-app>

5)在WEB-INF下创建一个dispatcherServlet-servlet.xml文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4     xmlns:context="http://www.springframework.org/schema/context"
 5     xmlns:mvc="http://www.springframework.org/schema/mvc"
 6     xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
 7         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 8         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
 9     
10     <!-- 增加注解扫描 -->
11     <context:component-scan base-package="com.sky.*"/>
12     
13     <!-- 注解驱动 -->
14     <mvc:annotation-driven/>
15     
16     <!--配置视图解析器，方便页面返回  -->
17     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
18         <property name="prefix" value="/WEB-INF/views/"></property>
19         <property name="suffix" value=".jsp"></property>
20     </bean>
21 </beans>

6)在/BMS/src/main/resources下创建几个配置文件

　　1.applicationContext.xml

　　2.dbconfig.properties

　　3.mybatis-config.xml

　　4.以及一个空的文件夹mapper，用于存放和dao层的接口相映射的xml文件

配置applicationContext.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4     xmlns:context="http://www.springframework.org/schema/context"
 5     xmlns:aop="http://www.springframework.org/schema/aop"
 6     xmlns:tx="http://www.springframework.org/schema/tx"
 7     xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
 8         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 9         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
10         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
11         
12     <!-- Spring的配置文件 -->
13     <context:property-placeholder location=    "classpath:dbconfig.properties" />
14     <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
15         <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
16         <property name="driverClass" value="${jdbc.driverClass}"></property>
17         <property name="user" value="${jdbc.user}"></property>
18         <property name="password" value="${jdbc.password}"></property>
19     </bean>    
20     
21     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
22         <!-- 指定mybatis全局配置文件的位置 -->
23         <property name="configLocation" value="classpath:mybatis-config.xml"></property>
24         <property name="dataSource" ref="pooledDataSource"></property>
25         <!-- 指定mybatis，mapper文件的位置 -->
26         <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
27     </bean>
28     
29     <!-- 配置扫描器，将mybatis接口的实现加入到ioc容器中 -->
30     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
31         <!--扫描所有dao接口的实现，加入到ioc容器中 -->
32         <property name="basePackage" value="com.sky.dao"></property>
33     </bean>
34 </beans>

配置dbconfig.properties

1 jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/test
2 jdbc.driverClass=com.mysql.jdbc.Driver
3 jdbc.user=root
4 jdbc.password=123456

配置mybatis-config.xml

 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 <configuration>
 6     
 7     <settings>
 8         <setting name="mapUnderscoreToCamelCase" value="true"/>
 9     </settings>
10     
11     <typeAliases>
12         <package name="com.sky.bean"/>
13     </typeAliases>
14     
15     <plugins>
16         <plugin interceptor="com.github.pagehelper.PageInterceptor">
17             <!--分页参数合理化  -->
18             <property name="reasonable" value="true"/>
19         </plugin>
20     </plugins>
21     
22 </configuration>

7)创建一个web测试流程

 1 package com.sky.beans;
 2 
 3 public class User {
 4     private String userId;
 5     private String name;
 6     private String address;
 7     
 8     public String getUserId() {
 9         return userId;
10     }
11     public void setUserId(String userId) {
12         this.userId = userId;
13     }
14     public String getName() {
15         return name;
16     }
17     public void setName(String name) {
18         this.name = name;
19     }
20     public String getAddress() {
21         return address;
22     }
23     public void setAddress(String address) {
24         this.address = address;
25     }
26     
27 }

 1 package com.sky.controller;
 2 
 3 import javax.servlet.http.HttpServletRequest;
 4 import javax.servlet.http.HttpServletResponse;
 5 
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.stereotype.Controller;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 
10 import com.sky.beans.User;
11 import com.sky.service.UserService;
12 
13 @Controller
14 public class UserController {
15     @Autowired
16     private UserService userService;
17     
18     @RequestMapping("user.do")
19     public String user(HttpServletRequest request,HttpServletResponse response){
20         String userId = request.getParameter("userId");
21         String name = request.getParameter("name");
22         String address = request.getParameter("address");
23         
24         User user = new User();
25         user.setUserId(userId);
26         user.setName(name);
27         user.setAddress(address);
28         
29         int i = userService.userService(user);
30         System.out.println(i == 1 ? "添加成功" : "添加失败");
31         return "";
32     }
33     
34 }

 1 package com.sky.service;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Service;
 5 
 6 import com.sky.beans.User;
 7 import com.sky.dao.UserMapper;
 8 
 9 @Service
10 public class UserService {
11     @Autowired
12     private UserMapper userMapper;
13     
14     public int userService(User user){
15         return userMapper.doSave(user);
16     }
17     
18 }

1 package com.sky.dao;
2 
3 import com.sky.beans.User;
4 
5 public interface UserMapper {
6         
7     public int doSave(User user);
8     
9 }

1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
3 <mapper namespace="com.sky.dao.UserMapper">
4     
5     <insert id="doSave" parameterType="com.sky.beans.User" >
6         insert into user values(#{userId},#{name},#{address})
7       </insert>
8     
9 </mapper>

输出结果为:

这只是一个粗糙版的ssm整合，还可以添加许多其他的组件例如bootStrap jQuery等静态资源，以及整合其他实际开发中需要用到的技术和集成个性化技术。
