#1, Build.gradle configuration note, added the war plug-in, the dependency of Jstl, Tomcat-embed-jasper, so as to run the JSP page.

buildscript {    ext {        springBootVersion = ‘1.5.3.RELEASE‘    }    repositories {        maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }    }    dependencies {        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")    }}apply plugin: ‘java‘apply plugin: ‘idea‘apply plugin: ‘org.springframework.boot‘apply plugin: ‘war‘version = ‘0.0.1-SNAPSHOT‘sourceCompatibility = 1.8repositories {    maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }}dependencies {    compile ‘jstl:jstl:1.2‘    compile ‘org.apache.tomcat.embed:tomcat-embed-jasper‘    compile(‘org.springframework.boot:spring-boot-starter-web‘)    testCompile(‘org.springframework.boot:spring-boot-starter-test‘)}

#2, Spring boot import file configuration Note: Inherit SpringBootServletInitializer , open@ServletComponentScan

@SpringBootApplication@ServletComponentScanpublic class DemoApplication extends SpringBootServletInitializer {    @Override    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {        return builder.sources(DemoApplication.class);    }    public static void main(String[] args) {        SpringApplication.run(DemoApplication.class, args);    }}

The correct posture of #3 and servlet/jsp

# #3.1, servlet Note: Using the @WebServlet Configure page access address, access to the JSP page requires the use of a full relative path/WEB-INF/jsp/index.jsp

@WebServlet( urlPatterns = {"/index"})public class Index extends HttpServlet {    protected void doPost(HttpServletRequest req, HttpServletResponse resp)            throws ServletException, IOException {        doGet(req, resp);    }    public void doGet(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        request.getRequestDispatcher("/WEB-INF/jsp/index.jsp").forward(request, response);    }}

# #3.2, Controller mode using JSP Note: With application.properties configuration, you can use a simplified JSP path ###①application.properties configuration

spring.mvc.view.prefix=/WEB-INF/jsp/spring.mvc.view.suffix=.jsp

###②controller Writing

@Controller    public class HelloController {        @RequestMapping("/index1")        public ModelAndView index(ModelAndView view) {            view.setViewName("index");            return view;        }    }

#4, run the method right-type the port file directly run Bootrun execute gradle build,java-jar Xxx.war
