Spring Boot 可以打包为 war 或 jar 文件。 以两种方式发布应用

2. Spring Boot 打包为 war

创建 Spring Boot web 项目: course13

        </plugins>
    </build>

</project>

2.2 创建 webapp 目录  85

打包_spring

指定 webapp 是 web 应用目录

打包_spring_02

main.jsp

<%--打包为jar  88--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
     main.jsp ，显示数据 ${data}
</body>
</html>

2.3 创建 jsp 文件  85

<%--演示打包方式  85--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>index.jsp</title>
</head>
<body>
    index.jsp , 显示controller中的数据  ${data}
</body>
</html>

2.4 创建 JspWarController  85

JspController

package com.bjpowernode.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

//演示打包方式打包为war文件  85
@Controller
public class JspController {

    @RequestMapping("/main")
    public String main(Model model){
        model.addAttribute("data","SpringBoot打包为war文件");
        return "index";
    }
}

2.5 设置视图解析器  85

applicationg.properties

server.port=9001
server.servlet.context-path=/myjsp

#指定视图解析器  85
http://spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

2.6 启动主类，在浏览器访问地址 index

访问浏览器 http://localhost:9001/myjsp/main

打包_maven_03

2.7 主启动类继承 SpringBootServletInitializer  86-87

继承 SpringBootServletInitializer 可以使用外部 tomcat。SpringBootServletInitializer 就是原有的 web.xml 文件的替代。使用了嵌入式 Servlet,默认是不支持 jsp。

 继承这个类SpringBootServletInitializer

 才能使用独立tomcat服务器

JspApplication
package com.bjpowernode;

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;

/**
 * SpringBootServletInitializer: 继承这个类， 才能使用独立tomcat服务器  86
 */
@SpringBootApplication
public class JspApplication extends SpringBootServletInitializer {

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


    @Override
    protected SpringApplicationBuilder configure
            (SpringApplicationBuilder builder) {

       return builder.sources(JspApplication.class);
    }
}

指定项目 package 是 war

<!--打包类型-->
<packaging>war</packaging>

maven package 打包

打包_打包操作_04

发布打包后的 war 到 tomcat

在浏览器访问 web 应用

把打包结果放到tomcat的webapps目录下E:\java\dev2\apache-tomcat-9.0.65\webapps

启动tomcat，然后浏览器访问http://localhost:8080/myboots/main

打包_打包操作_05

            </plugin>
        </plugins>

4. Spring Boot 部署和运行方式总结  89-91

➢ 在 IDEA 中直接运行 Spring Boot 程序的 main 方法（开发阶段）

➢ 用 maven 将 Spring Boot 安装为一个 jar 包，使用 Java 命令运行

java -jar springboot-xxx.jar 

可以将该命令封装到一个 Linux 的一个 shell 脚本中（上线部署）

◼ 写一个 shell 脚本：

#!/bin/sh

java -jar xxx.jar

◼ 赋权限 chmod 777 run.sh

◼ 启动 shell 脚本： ./run.sh
