SpringMVC Idea 搭建 部署war

1.创建 Idea项目

使用Maven模板 创建 webApp模板项目

2.导入依赖 

<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>com.x</groupId><artifactId>jetty-x-file-server</artifactId><packaging>war</packaging><version>1.0-SNAPSHOT</version><name>jetty-x-file-server Maven Webapp</name><url>http://maven.apache.org</url><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><!--    <dependency>-->
<!--      <groupId>jakarta.servlet</groupId>-->
<!--      <artifactId>jakarta.servlet-api</artifactId>-->
<!--      <version>6.0.0</version>-->
<!--      <scope>provided</scope>-->
<!--    </dependency>--><!--    <dependency>-->
<!--      <groupId>org.springframework</groupId>-->
<!--      <artifactId>spring-webmvc</artifactId>-->
<!--      <version>6.2.0</version>-->
<!--    </dependency>--><!--    <dependency>-->
<!--      <groupId>com.fasterxml.jackson.core</groupId>-->

<!--    </dependency>--><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.8</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.3.18</version></dependency><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.4</version></dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.11.0</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.1.0</version><scope>provided</scope></dependency></dependencies><build><finalName>jetty-x-file-server</finalName></build>
</project>

3.web.xml更新至4.0

并且注册DispatcherServlet

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><!--1.注册DispatcherServlet --><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!--2.关联一个springmvc的配置文件:【servlet-name】-servlet.xml --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc-servlet.xml</param-value></init-param><!--3.启动级别=1  --><load-on-startup>1</load-on-startup></servlet><!--4. / 匹配所有的请求:(不包括.jsp) --><!--5. /* 匹配所有的请求:(包括.jsp) --><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

4.springmvc-servlet.xml

在resource目录下创建

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://www.springframework.org/schema/contexthttps://www.springframework.org/schema/context/spring-context.xsd"
><!--1.注解驱动  若用jackson需要在用properties来注入--><!--    JSON乱码问题--><mvc:annotation-driven><mvc:message-converters><bean class="org.springframework.http.converter.StringHttpMessageConverter"><constructor-arg value="UTF-8"/></bean><bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"><property name="objectMapper"><bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean"><property name="failOnEmptyBeans" value="false"/></bean></property></bean></mvc:message-converters></mvc:annotation-driven><!--2.静态资源--><mvc:default-servlet-handler/><!--3.扫描包    --><context:component-scan base-package="com.x.jettyxfileserver"/><!-- 文件上传配置   --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!--         请求的编码格式:必要和jsp的pageEncoding属性一致，以便正确读取表单的内容，默认为ISO-8859-1   --><property name="defaultEncoding" value="utf-8"/><!--           上传文件大小上限，单位为字节  (10485760=10M) --><property name="maxUploadSize" value="10485760"/><property name="maxInMemorySize" value="40960"/></bean><bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"><property name="locations"><list><value>classpath:application.properties</value></list></property></bean></beans>

5.创建application.properties

在resource目录下

filePath=${FILE_PATH:C:\\Program Files\\jetty\\jetty-distribution-9.2.1.v20140609(ssl)\\webapps\\ROOT\\html\\resources}
#filePath=C:\\Users\\RJ\\Desktop\\file

配置好tomcat

 

选择exploded的 

配置应用上下文，保存就可以了

6.maven打包

直接 clean package 就好了

放入 tomcat webApps

目录下。它会自动解包，生成文件夹项目
