我有以下目录结构/配置文件:
src/main/resource/config:
application.yml
application-dev.yml
application-sit.yml
注意根据“Bootiful Configuration”https://spring.io/blog/2015/01/13/configuring-it-all-out-or-12-factor-app-style-configuration-with-spring:
Spring Boot will read the
properties in src/main/resources/application.properties by default. If
a profile is active,it will also automatically reads in the
configuration files based on the profile name,like
src/main/resources/application-foo.properties where foo is the current
profile. If the Snake YML library is on the classpath,then it will
also automatically load YML files.
因为如果我将–spring.profiles.active = dev设置为一个,那么蛇YML jar就在类路径中
程序arg在eclipse运行配置中并使用它作为我的主要方法永远按预期工作
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);
// Check if the selected profile has been set as argument.
// if not the development profile will be added
addDefaultProfile(app,source);
app.run(args);
}
/**
* Set a default profile if it has not been set
*/
private static void addDefaultProfile(SpringApplication app,SimpleCommandLinePropertySource source) {
if (!source.containsProperty("spring.profiles.active")) {
app.setAdditionalProfiles(Constants.SPRING_PROFILE_DEVELOPMENT);
}
}
(请注意,上面的主要方法参考来自我的代码中使用的以下类:https://github.com/jarias/generator-jhipster-ember/blob/master/app/templates/src/main/java/package/_Application.java)
一切都按照预期的方式运行spring.profile.active = dev.这意味着两者:
application.yml(默认加载)和application-dev.yml(活动配置文件)属性文件被加载并排除application-sit.yml,因为sit不是活动配置文件.
这个嵌入式容器非常适合开发测试.但是,我希望通过生成战争并将其部署到独立的Tomcat8服务器来将其发布到生产环境中.
为此,我创建了WebApplicationInitializer的实现,Tomcat8服务器需要该实现在独立服务器上自动检测,引导和启动spring应用程序.
@Configuration
public class WebAppInit implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
ApplicationContext context = new AnnotationConfigApplicationContext(Application.class);
}
}
部署战争后,我收到以下错误,我尝试启动独立服务器并收到以下错误:
Caused by: org.springframework.beans.factory.enter code
hereBeanCreationException: Could not autowire field: private
java.lang.String com.titleFeed.config.db.DbConfigJPA.databaseUrl;
nested exception is java.lang.IllegalArgumentException: Could not
resolve placeholder spring.data.postgres.uri’ in string value
“${spring.data.postgres.uri}”
这意味着Tomcat Server / Spring没有加载application-dev.yml,因为它包含属性:spring.data.postgres.uri
所以我尝试了以下两种解决方案
>在tomcat / bin / catalina.sh中添加-Dspring.profiles.active = dev到JAVA_OPTS
>将spring.profiles.active = dev添加到tomcat / conf / catalina.properties
他们都没有工作.如何让独立的tomcat服务器加载与spring.profiles.active属性关联的yml文件.
它适用于从eclipse启动的嵌入式springboot服务器,但不适用于独立服务器?
EDIT1:M.Deinum – 在下面实现了您建议的解决方案,但仍然出现以下错误:
引起:java.lang.IllegalArgumentException:无法在字符串值“${spring.data.postgres.uri}中解析占位符’spring.data.postgres.uri’
似乎-Dspring.profiles.active = dev没有得到设置.
@Configuration
public class WebAppInit extends SpringBootServletInitializer {
@Override
protected WebApplicationContext createRootApplicationContext(
ServletContext servletContext) {
log.info("Properly INITALIZE spring CONTEXT");
ApplicationContext context = new AnnotationConfigApplicationContext(Application.class);
servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,context);
return super.createRootApplicationContext(servletContext);
}
}
编辑2 ACV: – 在启动脚本中添加“–spring.profiles.active = dev”作为JAVA_OPTS变量的一部分:tomcat / bin / catalina.sh不是一个可行的选项
例如:
JAVA_OPTS="$JAVA_OPTS --spring.profiles.active=dev ...etc
给出以下错误:
Unrecognized option: –spring.profiles.active=dev Error: Could not
create the Java Virtual Machine.”
spring:
profiles:
active: dev
重新部署战争.去了爆炸的tomcat目录位置以确保属性存在webapps / Feedserver / WEB-INF / classes / config / application.yml
问题仍然存在.
编辑4:在tomcat展开的webdir下添加了application.properties:webapps / Feedserver / WEB-INF / classes / application.properties:
spring.profiles.active=dev
spring.data.postgres.uri=jdbc:postgresql://localhost:5432/Feedserver
重新启动tomcat并且问题仍然存在.
它似乎没有拿起application.properties或application.yml
编辑5使用推荐的方法启动外部容器的spring boot服务器:
@Configuration
public class WebAppInit extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
编辑6:
我将-Dspring.profiles.active = dev添加到了start命令args:
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java -Djava.util.logging.config.file=/Users/shivamsinha/Desktop/Programming/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Dlog4j.rootLevel=ERROR -Dlog4j.rootAppender=console -DENV=dev -Dlog4j.configuration=/WEB-INF/classes/properties/log4j.properties -DTOMCAT_DIR=WEB-INF/classes/ -Djava.endorsed.dirs=/Users/shivamsinha/Desktop/Programming/tomcat/endorsed -classpath /Users/shivamsinha/Desktop/Programming/tomcat/bin/bootstrap.jar:/Users/shivamsinha/Desktop/Programming/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/Users/shivamsinha/Desktop/Programming/tomcat -Dcatalina.home=/Users/shivamsinha/Desktop/Programming/tomcat -Djava.io.tmpdir=/Users/shivamsinha/Desktop/Programming/tomcat/temp org.apache.catalina.startup.Bootstrap -Dspring.profiles.active=dev start

将spring profile args传递给Tomcat 8有两种选择.
1.将其设置为环境变量
Tomcat允许您在启动过程中调用的CATALINA_HOME / setenv.sh或CATALINA_BASE / setenv.sh中设置环境配置.
setenv.sh:
export SPRING_PROFILES_ACTIVE=dev
您可能还想在其中创建一个src / main / resources / banner.txt:
active profiles :: ${spring.profiles.active}
它在你的IDE中不起作用(它从你的jar / war的MANIFEST.MF文件中读取,如果你正常编译就不会有这个文件),但它在你关心的环境中真的很方便 – 一切都是你的当地的环境!
2.在执行类之前将其添加到启动脚本/命令
我修改了CATALINA_HOME / catalina.sh添加了一个声明的变量:
SPRING_PROFILE = “开发”
并且在所有相关的执行中将其添加到脚本中:
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \
-Dcatalina.base="\"$CATALINA_BASE\"" \
-Dcatalina.home="\"$CATALINA_HOME\"" \
-Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
-Dspring.profiles.active="\"$SPRING_PROFILE\"" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 "&"
显然这不是推荐的方法.但它的确有效!如果您确实拥有完全可复制的步骤,那么建议的方法随时可以发布答案,如果有效,我会接受它.
