idea下springboot打包成jar包和war包，並且可以在外部tomcat下運行訪問到

本文轉載自   查看原文   2018-05-15 17:57   20855    IDEA/ maven/ 開發經驗/ java經驗集錦/ 工作總結/ SpringBoot

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

然后聲明一點，下面打包的過程中，scope一直都是使用默認的范圍

<!--用於編譯jsp-->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <!--<scope>runtime</scope>-->
        </dependency>

 

把上一章創建好的spring boot項目打包成jar包和war包

【jar和war的區別就是：<packaging>標簽中的值更改就行 如下圖】

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

好了，這里先打成jar包

 使用maven的插件打包

 

 

 此時打包出來是有默認的名稱的jar包。然后在命令行下  運行起這個jar包。當然，jar包名字你需要去上面target路徑下去拷貝一下。【是不是很麻煩！！】

 

 然后訪問一下jsp頁面，因為我方法中加了打印，可以看到進來了

 

 但是頁面訪問不到：

 

 然后去jar包中查看一下，是因為jar包中沒有把webapp下的頁面文件等打包進去，當然訪問找不到頁面了【如果你想jar包也可以打包webapp下的頁面的話，可以：http://www.cnblogs.com/sxdcgaq8080/p/7715427.html】

 

 

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

 

【注意：如果嫌棄上面需要去拷貝jar包名字麻煩，想打包出來的名字是自定義的，在build下 規定即可】

在打包成war包

 看看 打包出來的war包名字是不是自定義的

 

 然后再運行war包

 這下是可以訪問到的了。

 

 看看war包下，是已經將頁面文件打包進去了。

 

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

好了 打包暫時打包成功了，直接拿着上面的war包放到一個外部的tomcat中跑起來試一下：

 

啟動一下：

 

 

不成功，按照下面 兩步走，解決當前這個在外部tomcat沒辦法運行起來並訪問的問題：

第一步：

　　 新建一個SpringBootStartApplication 繼承自 SpringBootServletInitializer

 作用：因為在外部容器部署的話，就不能依賴於Application的main函數了，而是要以類似於web.xml文件配置的方式來啟動Spring應用上下文，

　　　 此時我們需要在啟動類中繼承SpringBootServletInitializer並實現configure方法，這個類的作用與在web.xml中配置負責初始化Spring應用上下文的監聽器作用類似

【注意】：這個新建的類，與springboot的啟動類是同級的

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，這里有兩種方法，但是最終的目的都是讓springboot內嵌的tomcat在運行時不起作用而已。

　　　兩種方法任選一種！！！

　　　方法1：

　　　　　　

此時的pom.xml文件內容：

好了 這兩步完成，就可以按照上面的打包過程，打包為war包，然后放在外部的tomcat下，start.bat就可以訪問了。

好了 這兩步完成，就可以按照上面的打包過程，打包為war包，然后放在外部的tomcat下，start.bat就可以訪問了。

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

最后 啟動起來外部的tomcat ，在瀏覽器中訪問路徑如下：

需要加上你的項目名字，才能成功訪問。也就是這個文件夾的名字。

 

 

好了，到這里為止，終於能將一個springboot項目成功的打包並且放在外部的tomcat下啟動並且能夠成功訪問到頁面了。

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

最后的最后，你是否注意到pom.xml文件中 ，上一個章節到這一章節一直在糾結的一個問題：

 

到現在為止，已經剔除了內置的tomcat的情況下

如果指定scope范圍為provided的話

那么　　

　　1.啟動類啟動項目的情況下：

　　　　<scope>provided</scope>添加的情況，不能成功啟動，項目不能訪問

　　　　不添加的情況，使用默認的scope，可以成功啟動，項目可以訪問

　　　　訪問地址：http://localhost:8080/view/hello

　　2.在右側spring-boot:run啟動的情況下：

　　　　<scope>provided</scope>添加的情況，可以成功啟動，項目可以訪問

　　　　不添加的情況，使用默認的scope，可以成功啟動，項目可以訪問

　　　　訪問地址：http://localhost:8080/view/hello

　　3.在命令行啟動打包的war包情況下：

 　　　　<scope>provided</scope>添加的情況，可以成功啟動，項目可以訪問

　　　　不添加的情況，使用默認的scope，可以成功啟動，項目可以訪問

　　　　訪問地址：http://localhost:8080/view/hello

　　4.將war包部署在外部tomcat下運行的情況下：

　　　　<scope>provided</scope>添加的情況，可以成功啟動，項目可以訪問

　　　　不添加的情況，使用默認的scope，可以成功啟動，項目可以訪問

　　　　訪問地址：http://localhost:8080/firstDemo/view/hello
