微信开发准备(二)--springmvc+mybatis项目结构的搭建

转自：http://www.cuiyongzhi.com/post/34.html

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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113

<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">     <modelVersion>4.0.0</modelVersion>     <groupId>wechat.cuiyongzhi.com</groupId>     <artifactId>wechat</artifactId>     <packaging>war</packaging>     <version>0.0.1-SNAPSHOT</version>     <name>wechat</name>     <url>http://maven.apache.org</url>     <dependencies>         <!-- spring -->         <dependency>             <groupId>org.springframework</groupId>             <artifactId>spring-test</artifactId>             <version>3.2.0.RELEASE</version>         </dependency>         <dependency>             <groupId>org.springframework</groupId>             <artifactId>spring-webmvc</artifactId>             <version>3.2.0.RELEASE</version>         </dependency>         <dependency>             <groupId>org.springframework</groupId>             <artifactId>spring-core</artifactId>             <version>3.2.0.RELEASE</version>         </dependency>           <!-- mybatis -->         <dependency>             <groupId>org.mybatis</groupId>             <artifactId>mybatis</artifactId>             <version>3.1.1</version>         </dependency>         <dependency>             <groupId>org.mybatis</groupId>             <artifactId>mybatis-spring</artifactId>             <version>1.1.1</version>         </dependency>           <!-- mysql -->         <dependency>             <groupId>mysql</groupId>             <artifactId>mysql-connector-java</artifactId>             <version>5.1.21</version>         </dependency>           <!-- junit测试 -->         <dependency>             <groupId>junit</groupId>             <artifactId>junit</artifactId>             <version>4.11</version>             <scope>test</scope>         </dependency>           <!-- mysql阿里连接池druid -->         <dependency>             <groupId>com.alibaba</groupId>             <artifactId>druid</artifactId>             <version>0.2.9</version>         </dependency>           <!-- spring aop包 -->         <dependency>             <groupId>org.aspectj</groupId>             <artifactId>aspectjweaver</artifactId>             <version>1.7.1</version>         </dependency>           <!-- json包 -->         <dependency>             <groupId>com.alibaba</groupId>             <artifactId>fastjson</artifactId>             <version>1.2.7</version>         </dependency>           <!-- 文件上传包 -->         <dependency>             <groupId>commons-fileupload</groupId>             <artifactId>commons-fileupload</artifactId>             <version>1.2.2</version>         </dependency>           <!--servlet包 -->         <dependency>             <groupId>javax.servlet</groupId>             <artifactId>servlet-api</artifactId>             <version>3.0-alpha-1</version>         </dependency>           <dependency>             <groupId>javax.servlet.jsp</groupId>             <artifactId>jsp-api</artifactId>             <version>2.1</version>             <scope>provided</scope>         </dependency>           <dependency>             <groupId>javax.servlet</groupId>             <artifactId>jstl</artifactId>             <version>1.2</version>         </dependency>           <!-- 日志包 -->         <dependency>             <groupId>log4j</groupId>             <artifactId>log4j</artifactId>             <version>1.2.17</version>         </dependency>     </dependencies>     <build>         <finalName>wechat</finalName>     </build> </project>

②修改项目路径下的web.xml文件如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167

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：

1 2 3 4

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：

1 2 3 4 5 6 7 8 9 10 11 12 13

<?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 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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115

        <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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

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：
