更新時間：2017年04月20日 10:18:04 作者：dapengniao
這篇文章主要為大家詳細介紹了微信開發(fā)準備第二步，springmvc和mybatis項目結構的搭建，具有一定的參考價值，感興趣的小伙伴們可以參考一下
前面一篇有說道如何在MyEclipse中搭建maven項目，這里將繼續(xù)介紹如何在搭建好的基礎maven項目中引入我們常用的javaweb框架——SpringMVC！
①在建立好的maven項目中的pom.xml文件引入依賴，代碼如下：
<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"> <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測試 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- mysql阿里連接池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> <!-- 文件上傳包 --> <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修改項目路徑下的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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd http://www.springframework.org/schema/websocket http://www.springframework.org/schema/websocket/spring-websocket.xsd" id="WebApp_ID" version="3.0"> <display-name>com.cuiyongzhi.wechat</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value> <!-- ,classpath:spring-quartz.xml 用于做任務調(diào)度 任務定時都可以 --> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <context-param> <param-name>spring.profiles.active</param-name> <param-value>dev</param-value> </context-param> <context-param> <param-name>spring.profiles.default</param-name> <param-value>dev</param-value> </context-param> <context-param> <param-name>spring.liveBeansView.mbeanDomain</param-name> <param-value>dev</param-value> </context-param> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <listener> <description>spring監(jiān)聽器</description> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止內(nèi)存溢出 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <servlet> <description>spring mvc servlet</description> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>spring mvc 配置文件</description> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>interface_url-init_servlet</servlet-name> <servlet-class>com.cuiyongzhi.web.start.InterfaceUrlIntiServlet</servlet-class> <load-on-startup>1</load-on-startup> </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>300</session-timeout> </session-config> <error-page> <error-code>404</error-code> <location>/WEB-INF/error/error.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/WEB-INF/error/error.jsp</location> </error-page> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.gif</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.jpg</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <filter> <filter-name>DruidWebStatFilter</filter-name> <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class> <init-param> <param-name>exclusions</param-name> <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value> </init-param> </filter> <filter-mapping> <filter-name>DruidWebStatFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> <init-param> <!-- 允許清空統(tǒng)計數(shù)據(jù) --> <param-name>resetEnable</param-name> <param-value>true</param-value> </init-param> <init-param> <!-- 用戶名 --> <param-name>loginUsername</param-name> <param-value>cuiyongzhi</param-value> </init-param> <init-param> <!-- 密碼 --> <param-name>loginPassword</param-name> <param-value>123456</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>DruidStatView</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> <!-- 訪問監(jiān)控頁面：http://ip：port/projectName/druid/index.html --> <jsp-config> <jsp-property-group> <display-name>jspConfiguration</display-name> <url-pattern>*.jsp</url-pattern> <el-ignored>false</el-ignored> <scripting-invalid>false</scripting-invalid> <include-prelude>/WEB-INF/common/head.jsp</include-prelude> </jsp-property-group> </jsp-config> </web-app>
③添加數(shù)據(jù)庫配置信息，這里項目配置的數(shù)據(jù)庫為MySQL，在 resources下新建config.properties配置文件，設置如下：
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，設置如下：

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