简易搭建一个SpringMVC框架教程

Maven使用webapp模板创建项目

pom.xml引入SpringMVC坐标

代码语言：javascript复制

    <!--SpringMVC需要的包-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>4.3.25.RELEASE</version>
      <scope>compile</scope>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>4.3.25.RELEASE</version>
    </dependency>

添加java及resources路径，并标记路径

在resources下新建springMVC.xml配置文件

代码语言：javascript复制

<?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/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">
    
    <!-- 开启注解扫描-->
    <context:component-scan base-package="cn.swingz">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!-- 配置视图解析器 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 过滤静态资源 -->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />

    <!--    解决跨域请求-->
    <!-- 解决API接口跨域问题配置 Spring MVC 版本必须是 4.2 及以上 -->
    <mvc:cors>
        <mvc:mapping path="/**"
                     allowed-origins="*"
                     allowed-methods="POST, GET, OPTIONS, DELETE, PUT"
                     allowed-headers="Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"
                     allow-credentials="true"
                     max-age="3600" />
    </mvc:cors>

    <!--  开启springMVC注解支持  -->
    <mvc:annotation-driven/>

</beans>

在web.xml里配置前端控制器及防止乱码的过滤器

代码语言：javascript复制

<?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>

  <!-- 防止乱码的过滤器-->
  <filter>
    <filter-name>characterEncodingFilter</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>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>


  <!--配置前端控制器 -->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 加载springmvc.xml配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springMVC.xml</param-value>
    </init-param>
    <!-- 启动服务器，创建该servlet-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

新建Controller(eg:UserController)

代码语言：javascript复制

package cn.swingz.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class UserController {

    @RequestMapping(value = "regist",method = RequestMethod.GET)
    public String regist(String mail,String password){
        System.out.println(mail);
        System.out.println(password);
        return "regist success";
    }
}

Maven引入tomcat，部署项目

pom.xml设置

代码语言：javascript复制

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <path>/</path>
        <port>8089</port>
        <uriEncoding>UTF-8</uriEncoding>
    </configuration>
</plugin>
