使用Maven进行web项目创建
-
eclipse中配置Maven基础环境
-
在pom.xml中引入相关依赖（SSM）
<properties> <servlet-version>3.0.1</servlet-version> <jsp-version>2.2</jsp-version> <jstl-version>1.2</jstl-version> <spring-version>4.1.6.RELEASE</spring-version> <log4j-version>1.2.17</log4j-version> <jackson-version>2.4.1</jackson-version> <tomcat-version>2.2</tomcat-version> </properties> <dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${servlet-version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl-version}</version> </dependency> <!-- spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-version}</version> </dependency> <!-- log4j 日志 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j-version}</version> </dependency> <!-- jackson --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson-version}</version> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> </resources> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>${tomcat-version}</version> <configuration> <port>80</port> <path>/</path> </configuration> </plugin> </plugins> </build>注意：在servlet-api和jsp-api依赖时一定要添加<scope>provided</scope>，代表编译器生效，但是并不会打包发布到tomcat中。

在webapp目录下完善META-INF、WEB-INF、web.xml
<?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"> <!-- 上下文参数 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:applicationContext-*.xml</param-value> </context-param> <!-- 监听器 --> <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> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 字符编码过滤器 --> <filter> <filter-name>encoding</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> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> -
在resource目录下完善applicationContext-spring.xml
