Freemark与Spring MVC的整合

1、项目的视图存放位置

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"

	<!-- 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 -->

	<!-- freemarker config -->
	<bean id="freemarkerConfig"

		</property>

	</bean>

	<!-- View resolvers can also be configured with ResourceBundles or XML files.

		resource bundle resolver. -->
	<bean id="viewResolver"

	</bean>

</beans>

3、Spring相关配置文件的加载

	<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

Spring4 + Spring MVC + MyBatis 整合思路

1.Spring框架的搭建这个很简单,只需要web容器中注册org.springframework.web.context.ContextLoaderListener,并指定spring加载配置文件,那么spring容器搭建完成.(当然org.springframework的核心jar包需要引入) 当然为了更加易用支持J2EE应用,一般我们还会加上如下: Spring监听HTTP请求事件:org.springframework.web.context.request.RequestContext

spring mvc + mybatis 整合框架

首先放几个该放的包(注意:后面两个mybatis-spring-1.1.1.jar mybatis-3.1.1.jar是因为不导入这两个包sql就不会在控制台打印,感觉调试的时候有点不方便,不需要的话就没什么) 下面还有几个包是用来使用json的,就可以直接返回字符串在网页上,如果不导入直接访问方法的话,会返回一个字符串名的jsp 文件目录如下: 接下来就是几个配置文件 applicationContext-dao.xml <beans xmlns="http://www.springfr
