ssm（springmvc+spring+mybatis）框架的搭建

由于前段时间开发项目用的是struct2，这次自己学了一下springmvc之后，想用springmvc替代struct2，并且结合spring+mybatis来开发，开发的基本要素在下面慢慢陈诉。

以下是我的整个项目的目录结构：



然后我结合了maven进行开发，pom.xml文件信息如下：

整个项目开发所需要的jar包有了以后，对spring和mybatis的整合，xml文件为applicationContext-mybatis.xml，具体代码如下：

<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- 引入配置文件 -->

<bean id="propertyConfigurer"

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="location" value="classpath:db.properties" />

</bean>

<!-- 数据源 -->

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"

p:driverClassName="${jdbc.driver}"

p:url="${jdbc.url}"

p:username="${jdbc.username}"

p:password="${jdbc.password}" />

<!-- SqlSessionFactory配置 -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"

p:dataSource-ref="dataSource" p:typeAliasesPackage="com.yc.ssm.entity"

p:mapperLocations="classpath:mapper/*Mapper.xml" />

<!-- 自动构建mapper的实现对象 -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"

p:basePackage="com.yc.ssm.mapper" p:sqlSessionFactoryBeanName="sqlSessionFactory" />

<!-- 1.配制事务管理器 -->

<bean id="transactionManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager"

p:dataSource-ref="dataSource" />

<!-- 2.配制事务关联 -->

<tx:annotation-driven transaction-manager="transactionManager" />

</beans>

spring扫包的代码文件applicationContext-com.xml如下：

<?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:mvc="http://www.springframework.org/schema/mvc"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">

<!-- 自动扫描 -->

<context:component-scan base-package="com.yc.ssm">

<context:exclude-filter type="annotation"

expression="org.springframework.stereotype.Controller"/>

<context:exclude-filter type="annotation"

expression="org.springframework.web.bind.annotation.ControllerAdvice"/>

</context:component-scan>

</beans>

其中的jdbc属性文件为db.properties,代码如下：

jdbc.driver=oracle.jdbc.driver.OracleDriver

jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl

jdbc.username=test

jdbc.password=a

可以用junit写个测试方法检查是否配置成功，检查方法如下：

package com.yc.test;

import static org.junit.Assert.assertNotNull;

import java.sql.Connection;

import org.apache.ibatis.session.SqlSession;

import org.apache.ibatis.session.SqlSessionFactory;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration("classpath:applicationContext-mybatis.xml")

public class ConnTest {

@Autowired

private SqlSessionFactory sqlSessionFactory;

@Test

public void testConn() {

Connection con=null;

SqlSession session=sqlSessionFactory.openSession();

con=session.getConnection();

assertNotNull("数据库连接失败",con);

}

}

测试成功后，接下来呢？肯定是轮到了springmvc了，spring-mvc.xml代码如下：

<?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:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->

<context:component-scan base-package="com.yc.ssm.controller" >

<context:include-filter type="annotation"

expression="org.springframework.stereotype.Controller"/>

<context:include-filter type="annotation"

expression="org.springframework.web.bind.annotation.ControllerAdvice"/>

</context:component-scan>

<mvc:annotation-driven></mvc:annotation-driven>

<mvc:default-servlet-handler/>

<!--避免IE执行AJAX时，返回JSON出现下载文件 -->

<bean id="mappingJacksonHttpMessageConverter"

class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

</list>

</property>

</bean>

<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

<property name="messageConverters">

<list>

<ref bean="mappingJacksonHttpMessageConverter" /><!-- JSON转换器 -->

</list>

</property>

</bean>

<!-- 定义跳转的文件的前后缀 ，视图模式配置-->

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->

<property name="prefix" value="/WEB-INF/jsp/" />

<property name="suffix" value=".jsp" />

</bean>

<!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->

<bean id="multipartResolver"

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<!-- 默认编码 -->

<property name="defaultEncoding" value="utf-8" />

<!-- 文件大小最大值 -->

<property name="maxUploadSize" value="10485760000" />

<!-- 内存中的最大值 -->

<property name="maxInMemorySize" value="40960" />

</bean>

</beans>

再配置web.xml：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">

<display-name>Archetype Created Web Application</display-name>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext*.xml;</param-value>

</context-param>

<context-param>

<param-name>logbackConfigLocation</param-name>

<param-value>classpath:logback.xml</param-value>

</context-param>

<filter>

<filter-name>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<async-supported>true</async-supported>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<listener>

<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>

</listener>

<servlet>

<servlet-name>SpringMVC</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:spring-mvc.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

<async-supported>true</async-supported>

</servlet>

<servlet-mapping>

<servlet-name>SpringMVC</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>/index.jsp</welcome-file>

</welcome-file-list>

<session-config>

<session-timeout>15</session-timeout>

</session-config>

</web-app>

最后测试框架有没有成功，index.jsp中写个超链接

<a href="test">测试</a>

然后在controller层测试写测试代码：

//测试是否能到test.jsp中

@RequestMapping("/test")

public String test(){

return "test";

}

整个框架跑通，自己去实现自己要实现的功能。
