接着上一章走呗:http://www.cnblogs.com/sxdcgaq8080/p/7712874.html

然后声明一点,下面打包的过程中,scope一直都是使用默认的范围

<!--用于编译jsp--> 
        <dependency> 
            <groupId>org.apache.tomcat.embed</groupId> 
            <artifactId>tomcat-embed-jasper</artifactId> 
            <!--<scope>runtime</scope>--> 
        </dependency>

把上一章创建好的spring boot项目打包成jar包和war包

【jar和war的区别就是:<packaging>标签中的值更改就行 如下图】

=====================================================================================================================================

好了,这里先打成jar包

 使用maven的插件打包

 此时打包出来是有默认的名称的jar包。然后在命令行下  运行起这个jar包。当然,jar包名字你需要去上面target路径下去拷贝一下。【是不是很麻烦!!】

 然后访问一下jsp页面,因为我方法中加了打印,可以看到进来了

 

 但是页面访问不到:

 

 然后去jar包中查看一下,是因为jar包中没有把webapp下的页面文件等打包进去,当然访问找不到页面了【如果你想jar包也可以打包webapp下的页面的话,可以:http://www.cnblogs.com/sxdcgaq8080/p/7715427.html】

 

好吧,jar包既然打包不成功访问,那就打包war包:就把jar改成war就好了

 

【注意:如果嫌弃上面需要去拷贝jar包名字麻烦,想打包出来的名字是自定义的,在build下 规定即可】

在打包成war包

 看看 打包出来的war包名字是不是自定义的

 

 然后再运行war包

 这下是可以访问到的了。

 

 看看war包下,是已经将页面文件打包进去了。

=======================================================================================================================================

好了 打包暂时打包成功了,直接拿着上面的war包放到一个外部的tomcat中跑起来试一下:

 

启动一下:

不成功,按照下面 两步走,解决当前这个在外部tomcat没办法运行起来并访问的问题:

第一步:

   新建一个SpringBootStartApplication 继承自 SpringBootServletInitializer

 作用:因为在外部容器部署的话,就不能依赖于Application的main函数了,而是要以类似于web.xml文件配置的方式来启动Spring应用上下文,

    此时我们需要在启动类中继承SpringBootServletInitializer并实现configure方法,这个类的作用与在web.xml中配置负责初始化Spring应用上下文的监听器作用类似

【注意】:这个新建的类,与springboot的启动类是同级的

package com.sxd; 

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class SpringBootStartApplication extends SpringBootServletInitializer{

@Override 
</span><span style="color: #0000ff">protected</span><span style="color: #000000"> SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
    </span><span style="color: #0000ff">return</span> application.sources(FirstdemoApplication.<span style="color: #0000ff">class</span><span style="color: #000000">); 
} 

}

第二步:

   修改pom.xml文件,这里有两种方法,但是最终的目的都是让springboot内嵌的tomcat在运行时不起作用而已。

   两种方法任选一种!!!

   方法1:

      

此时的pom.xml文件内容:

好了 这两步完成,就可以按照上面的打包过程,打包为war包,然后放在外部的tomcat下,start.bat就可以访问了。

好了 这两步完成,就可以按照上面的打包过程,打包为war包,然后放在外部的tomcat下,start.bat就可以访问了。

========================================================================================================================================

最后 启动起来外部的tomcat ,在浏览器中访问路径如下:

需要加上你的项目名字,才能成功访问。也就是这个文件夹的名字。

好了,到这里为止,终于能将一个springboot项目成功的打包并且放在外部的tomcat下启动并且能够成功访问到页面了。

========================================================================================================================

最后的最后,你是否注意到pom.xml文件中 ,上一个章节到这一章节一直在纠结的一个问题:

到现在为止,已经剔除了内置的tomcat的情况下

如果指定scope范围为provided的话

那么  

  1.启动类启动项目的情况下:

    <scope>provided</scope>添加的情况,不能成功启动,项目不能访问

    不添加的情况,使用默认的scope,可以成功启动,项目可以访问

    访问地址:http://localhost:8080/view/hello

  2.在右侧spring-boot:run启动的情况下:

    <scope>provided</scope>添加的情况,可以成功启动,项目可以访问

    不添加的情况,使用默认的scope,可以成功启动,项目可以访问

    访问地址:http://localhost:8080/view/hello

  3.在命令行启动打包的war包情况下:

     <scope>provided</scope>添加的情况,可以成功启动,项目可以访问

    不添加的情况,使用默认的scope,可以成功启动,项目可以访问

    访问地址:http://localhost:8080/view/hello

  4.将war包部署在外部tomcat下运行的情况下:

    <scope>provided</scope>添加的情况,可以成功启动,项目可以访问

    不添加的情况,使用默认的scope,可以成功启动,项目可以访问

    访问地址:http://localhost:8080/firstDemo/view/hello
