Windows 10 上使用 Maven 和 Jetty 的 Java 应用程序：HTTP 错误：503 访问 / 时出现问题。原因：服务不可用

问题描述 投票：0回答：1

我尝试在 Windows 10 上使用 

mvn -Dluke.confdir=file://C:\\ecoconfig\\ecomodules-calculation.conf jetty:run
从命令提示符运行一个大约有九年历史的 Java 应用程序，它会给出以下警告（三个点代表各个文件中的很多行）：

[WARNING] Failed startup of context o.e.j.m.p.JettyWebAppContext@6bb1d205{/,[file:///C:/Users/03260585/Work%
20Folders/ecomodules-calculation/WebContent/, jar:file:///C:/Users/03260585/.m2/repository/io/springfox/
springfox-swagger-ui/2.8.0/springfox-swagger-ui-2.8.0.jar!/META-INF/resources],STARTING}

使用单个 

\
而不是 
\\
并将文件路径用单引号或双引号引起来会产生相同的警告。以下行来自
applicationContext.xml
：

<util:properties id="propertyConfigurer" location="${luke.confdir}/ecomodules-calculation.conf" />

并且我怀疑如果我的初始命令在文件路径格式上没有问题，那么我按照留下的说明填写的

.conf
文件 以前的开发者有问题的内容。 
.conf
文件如下，我注释掉了最后两行，因为在 剩余的开发过程。除我插入的 
jdbc.username
、
jdbc.password
和 
jwt.secret
之外，所有内容均已预先填写。

jdbc.driverClassName=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/ecomodules?currentSchema=ecomodules
# Database username. Probably ecomodules. Configure as appropriate.
jdbc.username=correct_username
# Database user password. Configure as appropriate.
jdbc.password=correct_password

# Generate at least 256-bit key here
# example using openssl command:
# openssl rand -base64 32
# for convenience, here is one: /e+Azj4FkSAhlwtg0yyvcUPulrtxS66pRgvF04vNvvg=
# do not use it for other than local dev environments since it's not a platform secret
jwt.secret=7e+Azj4FkSAhlwtg0yyvcUPulrtxS66pRgvF04vNvvgt
jwt.issuer=Luonnonvarakeskus
jwt.cookieName=ECOMODULES_COOKIE
jwt.ttl=P7D

# SMTP service hostname for forgot password mechanism. smtprelay.ns.luke.fi in luke internal usage
#spring.mail.host=
#spring.mail.port=25

该应用程序在 

localhost:8080/
上提供，上面写着

HTTP ERROR: 503
Problem accessing /. Reason: 
Service Unavailable

我也尝试了

localhost:8080/index.html
，但那里显示了相同的错误。有人可以告诉我这里有什么问题吗？如何才能让应用程序正常运行？我没有 Java 开发经验，所以我对此很迷茫。

重新安装 Maven 和 Node.js 并取消注释 

.conf
文件中的最后几行解决了该问题。事实证明，即使未使用密码恢复，启动应用程序时 
spring.mail.host
和 
spring.mail.port
也应在 
.conf
文件中具有值。
