吴裕雄天生自然SPRINGBOOT开发实战SpringBoot Tomcat部署

如何在Tomcat Server上部署Spring Boot应用程序。
它包括三个步骤:
设置Spring Boot应用程序
创建Spring Boot WAR
将WAR部署到Tomcat

package com.lidihuo;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DemoRestController {
    @GetMapping("/hello")
    public String hello() {
        return "Hello User, have a nice day.";
    }
}

创建Spring Boot WAR
它利用了Spring Framework的Servlet 3.0支持，并允许我们在Servlet容器启动时配置应用程序。要创建用于部署的WAR，有 三个步骤:
在主类中扩展 SpringBootServletInitializer 类。
将嵌入式servlet容器标记为已提供。
将包装 JAR 更新为
在应用程序中实现上述三个步骤。

打开 SpringBootWarDeploymentExampleApplication.java 文件并初始化Tomcat所需的Servlet上下文。为实现相同目的，扩展了 SpringBootServletInitializer 接口。

public class SpringBootWarDeploymentExampleApplication extends SpringBootServletInitializer
{
}

覆盖 Configure 方法。
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) 
{
return application.sources(SpringBootWarDeploymentExampleApplication.class);
} 

package com.lidihuo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWarDeploymentExampleApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWarDeploymentExampleApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringBootWarDeploymentExampleApplication.class, args);
    }
}

 

 

 复制 路径并访问应用程序的 target 文件夹。我们在目标文件夹中找到了与pom.xml文件中指定的名称相同的WAR文件

部署将WAR文件添加到Tomcat
要部署WAR文件，请按照以下步骤操作:
下载并安装 Apache Tomcat Server (如果未安装)。
复制WAR文件(web-services.war)并将其粘贴到 webapps 文件夹

现在打开命令提示符并键入以下命令:

 

打开浏览器并调用URL http://localhost:8080/web-services/hello
