微信开发准备(二)--springmvc+mybatis项目结构的搭建

频道:技术分享 标签:菜鸟程序员微信平台开发Java-SpringMVC 时间:2016年03月03日 浏览:3538次 评论:11条

前面一篇有说道如何在MyEclipse中搭建maven项目,这里将继续介绍如何在搭建好的基础maven项目中引入我们常用的javaweb框架——SpringMVC!

①在建立好的maven项目中的pom.xml文件引入依赖,代码如下:

<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/maven-v4_0_0.xsd">

	<groupId>wechat.cuiyongzhi.com</groupId>
	<artifactId>wechat</artifactId>

	<version>0.0.1-SNAPSHOT</version>
	<name>wechat</name>
	<url>http://maven.apache.org</url>
	<dependencies>
		<!-- spring -->

	</build>
</project>

②修改项目路径下的web.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:web="http://java.sun.com/xml/ns/javaee" xmlns="http://java.sun.com/xml/ns/javaee"

	</jsp-config>

</web-app>

③添加数据库配置信息,这里项目配置的数据库为mysql,在 resources下新建config.properties配置文件,设置如下:

validationQuery=SELECT 1
jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc_username=root  
jdbc_password=123456789

④在 resources下新建spring.xml配置文件,设置如下:

<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

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-3.0.xsd">
	<!-- 引入属性文件 -->
	<context:property-placeholder location="classpath:config.properties" />
	<!-- 自动扫描(自动注入) -->
	<context:component-scan base-package="com.cuiyongzhi.web.service" />
	<context:component-scan base-package="com.cuiyongzhi.wechat.*" /> 
	
</beans>

⑤在 resources下新建spring-mvc.xml配置文件,设置如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context/spring-context-4.0.xsd 
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	<!-- 自动扫描controller包下的所有类,使其认为spring mvc的控制器 -->
	<context:component-scan base-package="com.cuiyongzhi.web.controller" />

	<!-- 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>
	</bean>

	<!-- 启动Spring MVC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">

				<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
			</list>
		</property>
	</bean>

	<!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp" />

	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="defaultEncoding">
			<value>UTF-8</value>
		</property>
		<property name="maxUploadSize">

		<property name="maxInMemorySize">

	</bean>
	
</beans>

⑥在 resources下新建spring-mybatis.xml配置文件,设置如下:

	<!-- myBatis文件 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
		<property name="mapperLocations" value="classpath:com/cuiyongzhi/web/mapping/*.xml" />
	</bean>

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

	</bean>
	<aop:config>
		<aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />
	</aop:config>

</beans>

⑦在 resources下新建log4j.properties配置文件,用于日志的输出等级以及输出位置设置,设置如下:

log4j.rootLogger=DEBUG,Console,File

#ERROR,WARN,INFO,DEBUG

log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Threshold=DEBUG
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

log4j.appender.File=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.File.File=${catalina.base}/wechatlogs/wechat.log
log4j.appender.File.Threshold=INFO
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.Append=true
log4j.appender.File.ImmediateFlush=true
log4j.appender.File.DatePattern=yyyy-MM-dd'.log'
log4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

到这里springmvc+mybatis的基本配置文件基本就完成了,大致的项目结构如下:

    博主,少了一个interface_url.properties配置文件,还有在mybatis配置文件中为何没引入config.properties?我试了引入一下一直报错
