【问题描述】：

我正在尝试在 maven 应用程序中运行战争文件。

因为我需要 azure 的 oauth2 b2c，所以我发现这很有用 code

我以前从未尝试过 Spring，所以我对它很陌生

我尝试使用mvn compile 和 JDK 1.7 进行编译，正如它在 github 中所说的那样

但我得到了一个错误：

找不到符号：Base64

在互联网上搜索我发现它受 Jdk 1.8 + 支持，并且导入错误，所以我进行了导入，并且成功了。

之后我做了mvn package，它也做了生成war文件和目标文件夹的包。

我运行了战争文件java -jar azure-b2c-oauth2.war

但是得到了这个错误：

【问题讨论】：

你不能用java -jar azure-b2c-oauth2.war命令运行war文件这个命令用来运行可执行的jar文件。你需要tomcat来运行war文件。
stackoverflow.com/questions/1842972/…
@AmitK 将 .war 文件放入 tomcat 文件夹就足够了？
@User100696 是的

标签： java spring eclipse maven azure

【解决方案1】：

你的 POM.xml 写的是 WAR，要么将其更改为 Jar，要么按原样使用此代码并将 war 打包，然后使用诸如 tomcat 之类的服务器解包并运行它。

您只能使用java -jar filename 运行 jar 文件，但由于您的 POM 设置为 war 包，因此您需要创建 .war 文件

【讨论】：

【解决方案2】：

以下命令运行不正确。

java -jar azure-b2c-oauth2.war

这仅适用于基于 jar 的打包，如果您选择将应用程序打包为 war 文件，则应参考您的服务器和 IDE 文档。

参考：http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-running-your-application.html

参考服务器部署：https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/

或

你可以使用下面的jar包spring boot，

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<!-- ... -->
<packaging>jar</packaging>
<!-- ... -->
</project>

然后使用java -jar azure-b2c-oauth2.jar
