20.springboot项目打包成war文件，在独立的Tomcat上运行

项目结构

 

1.新建springboot项目选择web起步依赖，其他依赖手动添加

 

详细代码

pom.xml文件

2.新建index.jsp

3.JspController类

package com.it.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
public class JspController {
 
    @RequestMapping("/main")
    public String main(Model model){
        model.addAttribute("data","springboot打包为war文件");
        return "index";
    }
 
}

4.application.properties文件

server.port=9001
server.servlet.context-path=/myjsp
 
#配置视图解析器
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp
 
 

5.主函数入口类，注意此时需要继承SpringBootServletInitializer这个类，才能够使用独立的tomcat服务器

package com.it;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.server.Jsp;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
 
/**
 * SpringBootServletInitializer:继承这个类，才能够使用独立的tomcat服务器
 */
 
@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);
 
    }
}

项目测试：

1.首先不继承SpringBootServletInitializer这个类使用idea内部的Tomcat启动，查看是否可以正常访问

 2.项目可以正常访问，继承SpringBootServletInitializer这个类，编写代码后，点击clean，然后再进行打包处理

 

 

3.选择该打包文件，右键 show in explorer打开该文件所在的文件夹地址，选择该文件进行复制。复制到Tomcat下的webapp目录下，此时运行Tomcat时就会自动发布该文件

5.然后进入Tomcat的bin目录，点击startup.bat

6. 弹出下图的命令行窗口，等它运行完成后不能关闭，可以最小化使其保持运行状态

 

7.此时回到tomcat的webapps目录，就可以看到myboot.war包已经自动解压好了，里面的文件和依赖都和原项目保持一致

 

8.现在就可以打开浏览器输入Tomcat默认端口号+项目路径进行访问了，这是独立的Tomcat，不需要再借助idea上的Tomcat进行启动了。

localhost:8080/myboot/main

8080:独立Tomcat的端口号

myboot：文件名称

main：方法的路径名（requestmapping）
