1、项目的视图存放位置

技术分享

2、整合Spring MVC 的配置，web.xml的配置如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
	<display-name></display-name>
	<!-- 加载spring容器 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext-*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- springMVC前端控制器 -->
	<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:springmvc.xml</param-value>
		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>

	<!--主页的配置 -->
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

2、FreeMarker与SpringMVC整合，首先，在springmvc的配置文件普通视图之前，加入freemarker的视图。Spring MVC的配置文件，

springmvc.xml

<?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-3.2.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-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/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

	<!-- 可以扫描controller、service、... 这里让扫描controller，指定controller的包 -->
	<context:component-scan base-package="com.controller"></context:component-scan>
	<!--静态资源的处理 -->
	<mvc:resources location="/resources/" mapping="/resources/**" />
	<!--mvc的注解开发 -->
	<mvc:annotation-driven></mvc:annotation-driven>
	
	<!-- freemarker config -->
	<bean id="freemarkerConfig"
		class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
		<property name="templateLoaderPath" value=http://www.mamicode.com/"/WEB-INF/ftl/" />>
3、Spring相关配置文件的加载
      3.1 db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/student
jdbc.username=root
jdbc.password=1234
      3.2 applicationContext-dao.xml

	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-3.2.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-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/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

	<!-- 加载db.properties文件中的内容，db.properties文件中key命名要有一定的特殊规则 -->
	<context:property-placeholder location="classpath:db.properties" />

	<!-- 配置数据源,dbcp -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value=http://www.mamicode.com/"${jdbc.driver}" />>
      3.3 applicationContext-transaction.xml
<beans xmlns="http://www.springframework.org/schema/beans"

        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

	<!-- 事务管理器 对mybatis操作数据库进行事务控制，spring使用jdbc的事务控制类 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 数据源 dataSource在applicationContext-dao.xml中已经配置 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
	<!-- 通知 -->
	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<!-- 传播行为 -->
			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />

		</tx:attributes>
	</tx:advice>

	<!-- aop -->
	<aop:config>
		<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.service.*.*(..))" />
	</aop:config>
</beans>
      3.4 applicationContext-service.xml
<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"

	<context:spring-configured />
	<!--扫描Service的package -->
	<context:component-scan base-package="com.service" />


</beans>
4、Mybatis相关的配置文件
      4.1 sqlMapConfig.xml
<?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>

	<!-- 全局setting配置 ，根据需要再添加 -->

	<!-- 配置别名 -->
	<typeAliases>
		<!-- 批量扫描别名 -->
		<package name="com.entity" />
	</typeAliases>

	<!-- 配置mapper 
	由于使用spring和mybatis的整合包进行整合，这了无需配置 
	但必须遵循：mapper.java和mapper.xml文件同名且在同一目录 -->
	<!--<mappers></mappers> -->
</configu
      4.2 NavMapper.xml
<?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">

<!-- namespace命名空间，作用就是对sql进行分类化管理，理解sql隔离 注意：使用mapper代理方法开发，namespace有特殊重要的作用 -->
<mapper namespace="com.mapper.NavMapper">

	<select id="findNavById" parameterType="int" resultType="nav">
		SELECT
		*
		FROM nav WHERE id=#{id}
	</select>

	<select id="findAll" resultType="nav">
		SELECT
		* FROM
		nav
	</select>

	<insert id="add" parameterType="nav">
		insert into nav(name)
		values(#{name})
	</insert>

	<update id="update" parameterType="nav">
		update nav set name=#{name}
		where id=#{id}
	</update>
	<delete id="delete" parameterType="int">
		delete from nav where id=#{id}
	</delete>
</mapper>
      4.3 NavMapper.java与NavMapper.xml

5、log4j相关的配置文件
# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
6、关于页面的放置

7、NavController的实现
import java.util.List;
import java.util.Map;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.entity.Nav;
import com.service.NavService;

@Controller
@RequestMapping("/navController")
public class NavController {
	@Resource
	private NavService navService;

	public void setNavService(NavService navService) {
		this.navService = navService;
	}

	@RequestMapping("/jsp")
	public String toJspPage() {
		return "index";
	}

	@RequestMapping("/freemark")
	public String toFreemarkPage(Map<String, Object> model) {
		List<Nav> navs = navService.findAll();
		model.put("navs", navs);
		return "top";
	}
}

8、访问测试
