外部弹簧启动配置

标签： java spring-boot tomcat centos

我的环境是Centos 7，Tomcat 8和Java 8 我开发了spring-boot应用程序。我想外部化application.properties中显示的参数，因此将它们复制到外部属性文件中。

在这里，application.proprerties文件（spring-boot应用程序）：

spring.datasource.username= ${db.username}
spring.datasource.password= ${db.password}

这是我的外部属性文件：

enter image description here

内容：

db.username=root
db.password=test

我已经在tomcat / bin文件夹中创建了setenv.sh文件以添加Java选项 这是我的setenv.sh：

enter image description here

内容：

JAVA_OPTS="$JAVA_OPTS -Dspring.config.additional-location=/home/centos/myjarvia/configuration/application.properties"

但是当tomcat启动时它失败。（即使catalina.out日志文件显示找到了属性文件...

catalina.out文件内容：

我不明白怎么了

1 个答案:

答案 0 :(得分：0)

  

只需将此添加到您的外部属性文件中

spring.datasource.username =提及数据库用户名

spring.datasource.password =提及数据库密码

  

它将自动覆盖

     

并删除db.username之类的其他内容
