idea下springboot打包成jar包和war包，并且可以在外部tomcat下运行访问到

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！！！
