SpringMVC Idea 搭建部署war的详细过程_Java

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>-->
<!--      <artifactid>jackson-databind</artifactid>-->
<!--      <version>2.17.2</version>-->
<!--    </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/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        https://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
