一、新建工程
1、使用idea新建maven專案，步驟如圖：
二、搭建springmvc環境
1、pom.xml匯入依賴包，配置xml如下
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.nanshen</groupId>
<artifactId>springmvc</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<name>springmvc Maven Webapp</name>
<!-- FIXME change it to the project's website -->
<url>http://www.example.com</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<spring.version>5.0.8.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<!--springmvc 核心包依賴-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>

<version>${spring.version}</version>
</dependency>
<dependency>

</dependency>
<!--servlet依賴-->
<dependency>

</dependency>
<!--mysql資料庫連線依賴-->
<dependency>

<artifactId>mysql-connector-java</artifactId>
<version>5.1.46</version>
</dependency>
<!--mybatis依賴-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
</project>
複製程式碼2、配置spring applicationContext.xml檔案
a、建立applicationContext.xml檔案：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
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">
</beans>
複製程式碼3、配置springmvc.xml檔案
a、建立springmvc.xml檔案：跟建立application.xml檔案操作一樣
b、配置springmvc.xml檔案：（如下圖）
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 配置包掃描器 -->
<context:component-scan base-package="com.nanshen.demo.controller"/>
<!-- 配置註解驅動 -->
<mvc:annotation-driven/>
<!-- 檢視解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--字首-->
<property name="prefix" value="/WEB-INF/views/"/>
<!--字尾-->
<property name="suffix" value=".jsp"/>
</bean>
<!--返回資料編碼設定-->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8" />
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
</beans>
複製程式碼Ps:此處需要配置返回資料編碼格式為UTF-8
4、配置web.xml檔案，用如下配置程式碼替換idea生成的web.xml檔案程式碼
<!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>
<display-name>Archetype Created Web Application</display-name>
<!--Spring MVC 配置 並新增監聽-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring/*</param-value>
</context-param>
<!-- 字元過濾器 傳值亂碼-->
<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>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--配置前端控制器 進行請求分發 DispatcherServlet本質也是一個Servlet -->
<servlet>
<!--名字可以自定義-->
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<!--標記容器啟動的時候就啟動這個servlet-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!--攔截所有-->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
複製程式碼至此，springmvc環境已經搭建完成，接下來是測試：
三、測試：
1、建立一個TestController
package com.nanshen.demo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletResponse;
@RestController
@RequestMapping("/test")
public class TestController {
@RequestMapping("/create")
public String test(HttpServletResponse response){
response.setCharacterEncoding("utf-8");
return "springmvc建立成功";
}
}
