如何在Spring Framework MVC应用程序中嵌入Tomcat？ [英] How do I embed Tomcat in a Spring Framework MVC application?

问题描述

我已经创建了所需的配置/控制器类。但是我不清楚我应该如何编排这些类来运行tomcat实例。我知道使用Spring启动它是一个使用SpringApplication.run（..）的问题。但我正在尝试探索Spring Boot之前使用的替代方法。我对Spring Framework有点新意，请原谅我的无知。我也没有使用任何只使用Java的XML配置

I have created the required configurations/controller classes. But it's not clear to me how I should orchestrate these classes to use run a tomcat instance. I know with spring boot it's a matter of using SpringApplication.run(..). But I'm trying to explore the alternate method used prior to Spring Boot. I'm a bit new to the Spring Framework so forgive my ignorance. I'm also not using any XML configuration only using Java

public class SpittrWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer
{

@Override //....
protected String[] getServletMappings(){
    return new String[] { "/" }; 
}

@Override //...
protected Class<?>[] getRootConfigClasses(){
    return new Class<?>[] { RootConfig.class };
}

@Override //.....
protected Class<?>[] getServletConfigClasses(){
    return new Class<?>[] { WebConfig.class };
}
}

我创建了一个控制器

@Controller
@RequestMapping("/")
public class HomeController {

    @RequestMapping(method = RequestMethod.GET)
    public String home(){
        return "home";
    }

POM文件：

    <dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.3.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>4.3.9.RELEASE</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

推荐答案

最后解决了我遇到的问题。我就像VitalyZ推荐的那样，在我的POM中添加了一个 Tomcat 的嵌入式实例。我在一个新类中配置了嵌入式tomcat实例。

Finally fixed the problem I was coming across. I added an embedded instance of Tomcat to my POM just like VitalyZ recommended. I configured the embedded tomcat instance in a new class.

在我的Pom文件中添加以下内容

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <version>8.5.15</version>
    </dependency>

创建一个名为Application.java的新类

public class Application {
    public static void main(String[] args) throws Exception {

        String webAppDirLocation = "src/main/";
        Tomcat tomcat = new Tomcat();

        //Set Port #
        tomcat.setPort(8080);

        StandardContext ctx = (StandardContext) tomcat.addWebapp("/", new File(webAppDirLocation).getAbsolutePath());

        tomcat.start();
        tomcat.getServer().await();
    }
}
