IDEA之maven（springmvc）项目

Posted 2020-07-30 code.world

1、在idea下创建maven项目（参考IDEA之web项目（maven项目）创建）

2、项目结构

3、web.xml

<!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 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
  <display-name>Archetype Created Web Application</display-name>

  <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 设置dispatchservlet的匹配模式，通过把dispatchservlet映射到/，默认servlet会处理所有的请求，包括静态资源 -->
  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 字符集过滤器 -->
  <filter>
  <filter-name>encodingFilter</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>
  <init-param>
  <param-name>forceEncoding</param-name>
    <param-value>true</param-value>
  </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

4、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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       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
            http://www.springframework.org/schema/context/spring-context.xsd"
       default-lazy-init="true">

    <!-- 通过mvc:resources设置静态资源，这样servlet就会处理这些静态资源，而不通过控制器 -->
    <!-- 设置不过滤内容，比如:css,jquery,img 等资源文件 -->
    <mvc:resources location="/*.html" mapping="/**.html" />
    <mvc:resources location="/css/*" mapping="/css/**" />
    <mvc:resources location="/js/*" mapping="/js/**" />
    <mvc:resources location="/images/*" mapping="/images/**" />

    <!-- 添加注解驱动 -->
    <mvc:annotation-driven />
    <!-- 默认扫描的包路径 -->
    <context:component-scan base-package="com.*" />

    <!-- mvc:view-controller可以在不需要Controller处理request的情况，转向到设置的View -->
    <!-- 像下面这样设置，如果请求为/，则不通过controller，而直接解析为/index.jsp -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
                  value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

5、pom.xml，配置项目需要的依赖

<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>test.com</groupId>
  <artifactId>test-com</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>test-com 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>

    <!-- spring begin -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring.version}</version>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>${spring.version}</version>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>

    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-aop</artifactId>
      <version>${spring.version}</version>
    </dependency>

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>
    <!-- spring end -->
  </dependencies>
  <build>
    <finalName>test-com</finalName>
  </build>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <spring.version>3.1.2.RELEASE</spring.version>
  </properties>
</project>

6、TestController.java

package com.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by sunjf on 2016/6/26.
 */
@Controller
public class TestController {

    @RequestMapping(value = "test1")
    public String test1(){
        System.out.println("sunjianfei");
        return "success";
    }

}

7、index.jsp

<html>
<body>
<h2>Hello World!</h2>
<form action="test1" method="post">
    <input type="submit" name="submit">
</form>

</body>
</html>

8、success.jsp

<html>
<body>
<h2>Hello Success!</h2>
</body>
</html>
