2020java框架教程之springMVC创建maven项目

1.创建web项目

2.导入依赖

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.2.8.RELEASE</version>
    </dependency>
</dependencies>

然后点击右侧的maven，然后刷新即可自动导入依赖

然后左侧项目结构就会出现相关jar包

3.修改web.xml文件

<!-- servlet配置 -->
<servlet>
  <servlet-name>springMVC</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <!-- springmvc配置文件默认的名字 springMVC-servlet.xml  -->
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:springMVC-servlet.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>
<!-- 解决 SpringMVC的 post 乱码 -->
<filter>
  <filter-name>requestContextFilter</filter-name>
  <filter-class>org.springframework.web.filter.RequestContextFilter</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>
<filter-mapping>
  <filter-name>requestContextFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

4.在resource文件夹下创建springMVC-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <mvc:annotation-driven enable-matrix-variables="true"/>
    <!-- 扫描 controller  -->
    <context:component-scan base-package="springmvc.controller"/>
    <!-- 视图解析器  -->
    <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>-->
        <property name="prefix" value="/WEB-INF/jsp/"/><!-- 前缀  -->
        <property name="suffix" value=".jsp"/><!-- 后缀  -->
    </bean>
</beans>

5.在WEB-INF下创建jsp文件夹

6.在java包下创建controller包，写个类，返回路径参数

@Controller
public class IndexController {
    @RequestMapping("/")
    public String home(){
        return "home";
    }
}

7.在web的jsp文件夹创建home.jsp文件

8.配置Tomcat

9.配置jdk插件

默认情况下 eclipse的maven项目使用jdk1.5编译，需要添加maven的jdk编译插件

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <maven.compiler.source>1.8</maven.compiler.source>
  <maven.compiler.target>1.8</maven.compiler.target>
</properties>

<build>
  <plugins>
    <!-- java 编译插件  -->
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.0</version>
      <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <encoding>${project.build.sourceEncoding}</encoding>
      </configuration>
    </plugin>
  </plugins>
</build>

maven项目配置tomcat

<!--配置 Tomcat 插件 -->
<plugin>
  <groupId>org.apache.tomcat.maven</groupId>
  <artifactId>tomcat7-maven-plugin</artifactId>
  <version>2.2</version>
  <configuration>
    <port>8001</port>
    <path>/springmvc</path>
  </configuration>
</plugin>
