快速搭建SpringMVC啟動(dòng)程序
運(yùn)行環(huán)境：
- idea
- jdk8
- 創(chuàng)建maven工程：
- 選擇Create from archetype，勾選org.apache.maven.archetypes:maven-archetype-wepapp
- 導(dǎo)入依賴：
<properties>
<spring.version>4.0.1.RELEASE</spring.version>
</properties>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
項(xiàng)目工程->右鍵->add framewords support-> 添加SpringMVC
注: 沒(méi)找到SpringMVC寝并，有可能添加但不完整(也有可能完整而不必執(zhí)行此步驟)：按ctrl+shift+alt+s打開Project Structure，打開Project Settings->Facets软吐，刪除Spring膘盖，再在add framewords support添加SpringMVC編輯web.xml

- 創(chuàng)建控制器：
package com.programcreek.helloworld.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloWorldController {
String message = "Welcome to Spring MVC!";
@RequestMapping("/hello")
public ModelAndView showMessage(
@RequestParam(value = "name", required = false, defaultValue = "World") String name) {
System.out.println("in controller");
ModelAndView mv = new ModelAndView("helloworld");
mv.addObject("message", message);
mv.addObject("name", name);
return mv;
}
}
- 創(chuàng)建helloworld.jsp(web/WEB-INF/views/)

- 運(yùn)行：
- 點(diǎn)擊右上角運(yùn)行處add Configuration鞋拟，點(diǎn)擊左上角"+"號(hào)添加新配置->tomcat Server->local->選擇本地的tomcat目錄->第二行Deployment->添加artifacts
- 點(diǎn)擊運(yùn)行衩椒，輸入網(wǎng)址http://localhost:8080/xxxx/hello?name=xxx
