注：此篇有些细节没写出，此文主要写重要的环节和需要注意的地方，轻喷

## 新建项目 ##

选择Gradle , 勾选java 和 web。之后就是设定项目路径和名称，这里就不啰嗦了。

build.gradle文件下导入所需要的包，刷新一下。

1 group 'com.benjious.createTest'
      2 version '1.0-SNAPSHOT'
      3 
      4 apply plugin: 'java'
      5 apply plugin: 'war'
      6 
      7 sourceCompatibility = 1.8
      8 
      9 repositories {
     10     mavenCentral()
     11 }
     12 
     13 dependencies {
     14     testCompile group: 'junit', name: 'junit', version: '4.11'
     15     testCompile group: 'junit', name: 'junit', version: '4.12'
     16 
     17 
     18     compile'org.springframework:spring-context:4.3.6.RELEASE'
     19     compile'org.springframework:spring-webmvc:4.3.6.RELEASE'
     20     compile'org.springframework:spring-test:4.3.6.RELEASE'
     21 }

贴出各个类的代码

1 public class MyWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
      2 
      3     @Override
      4     protected Class<?>[] getRootConfigClasses() {
      5         return new Class[]{RootConfig.class};
      6     }
      7 
      8     @Override
      9     protected Class<?>[] getServletConfigClasses() {
     10         return new Class[]{WebConfig.class};
     11     }
     12 
     13     @Override
     14     protected String[] getServletMappings() {
     15         return new String[] { "/" };
     16     }
     17 }
     18

1 //exclude : 过滤掉
      2 @Configuration
      3 @ComponentScan(basePackages = {"createtest"},excludeFilters = {@ComponentScan.Filter(type = FilterType.ANNOTATION,value = EnableWebMvc.class)})
      4 public class RootConfig {
      5 
      6 }
      7

1 @Configuration
      2 @EnableWebMvc
      3 @ComponentScan("createtest.web")
      4 public class WebConfig extends WebMvcConfigurerAdapter {
      5 
      6 
      7     @Bean
      8     public ViewResolver viewResolver() {
      9         InternalResourceViewResolver resolver = new InternalResourceViewResolver();
     10         resolver.setPrefix("/WEB-INF/view/");
     11         resolver.setSuffix(".jsp");
     12         return resolver;
     13     }
     14 
     15 
     16     @Override
     17     public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
     18         configurer.enable();
     19     }
     20 
     21 }

1 @Controller
      2 public class HomeControl {
      3 
      4     @RequestMapping("/home")
      5     public String home() {
      6         return "home";
      7     }
      8 
      9 }

1 <%@ page contentType="text/html;charset=UTF-8" language="java" %>
      2 <html>
      3 <head>
      4     <title>Home</title>
      5 </head>
      6 <body>
      7 <p>home界面</p>
      8 </body>
      9 </html>

## 配置Tomcat ##

首先配置好Tomcat ，下面是配置好的界面

[![配置tomcat][tomcat]][tomcat_tomcat]

[![配置Tomcat1][Tomcat1]][Tomcat1_Tomcat1]

运行项目， 访问 [http://localhost:8080/home/][http_localhost_8080_home]

[![界面][1297993-20180503210449391-321602810.png]][1297993-20180503210449391-321602810.png 1]

这里需要的是在配置 Tomcat 中，设置 Application Context ，例如 Application Context 为 “/home ” ，那么 该项目的服务器的根地址为 ：

[http://localhost:8080/home/][http_localhost_8080_home] ， 那么要显示 home.jsp 界面应该为： [http://localhost:8080/home/][http_localhost_8080_home]home .
