您好,登录后才能下订单哦!
环境:
建立一个maven-webapp项目:Create New Project
后点击next
然后next
可以选择默认自带的maven,还可以修改配置默认的maven的仓库地址使加快下载速度,或者本地安装的apache-maven-3.5.2。
然后next
然后finish.
添加pom依赖
创建好之后的项目目录如图所示
打开pom.xml,添加依赖
<?xml version="1.0" encoding="UTF-8"?> <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xuan</groupId> <artifactId>springmvc</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <name>springmvc Maven Webapp</name> <!-- FIXME change it to the project's website --> <url>http://www.example.com</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!--spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.3.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.5.RELEASE</version> </dependency> <!--注解--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.2.7.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.3</version> </dependency> <!-- java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> </dependencies> <build> <finalName>springmvc</finalName> <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.0.0</version> </plugin> <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.7.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.20.1</version> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>3.2.0</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> </plugins> </pluginManagement> </build> </project>
建立相应的目录
项目创建完成后,src-main下建立java目录后,是无法在该目录下创建新的包和java类等文件的。在idea中需要对目录进行标注。
File->Project Structure:
现在还没有创建对应的目录,然后创建目录后,选择对应的标注:
(引用自http://wiki.jikexueyuan.com/project/intellij-idea-tutorial/eclipse-java-web-project-introduce.html)
标注完后,建立如下的目录。
配置web.xml
如果用maven自动生成的web.xml,可能读取不到springmvc返回传入的参数值,应该要修改web.xml
直接在原来的文件上面修改:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <servlet> <servlet-name>mvc-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
新文件:
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Archetype Created Web Application</display-name> <servlet> <servlet-name>mvc-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
注意要替换原来文件web-app的属性
启动时也会默认在/WEB-INF目录下查找XXX-servlet.xml作为配置文件,XXX就是DispatcherServlet的名字,也可以手动配置路径,现在使用默认的方式,
在WEB-INF目录下面创建mvc-dispatcher-servlet.xml:
mvc-dispatcher-servlet.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" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd "> <context:component-scan base-package="com.xuan.springmvc.controller"/> <mvc:annotation-driven/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
添加views目录: 把index.jsp拖到此目录下面:
编辑代码路径/src/main/java,添加com.xuan.springmvc.controller包,增加MainController.java:
package com.xuan.springmvc.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class MainController { @RequestMapping(value = "/index") public String index() { return "index"; } }
配置tomcat服务
Configure...配置tomcat路径
绿色+号,把项目加到部署列表
输入服务器名称和选择tomcat版本。
绿色+号,把项目加到部署列表
注意要选择第二项:
最后启动tomcat服务运行调试,显示结果:
