Spring Boot YML和StandAlone Tomcat 8 Server

Question

我有以下目录结构/配置文件:

src/main/resource/config: 
application.yml 
application-dev.yml 
application-sit.yml

请注意根据" Bootiful Configuration " https://spring.io/blog/2015/01/13/configuring-it-all-out-or-12-factor-app-style-configuration-with-spring:

Spring Boot将默认读取src/main/resources/application.properties中的属性.如果配置文件处于活动状态,它还将根据配置文件名称自动读取配置文件,例如src/main/resources/application-foo.properties,其中foo是当前配置文件.如果Snake YML库在类路径上,那么它也会自动加载YML文件.

如果我--spring.profiles.active=dev在eclipse运行配置中设置为程序arg并且使用它作为我的主要方法,那么蛇YML jar在类路径中,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: application.yml(默认加载)和application-dev.yml(活动配置文件)属性文件都被加载并排除 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:

引起:org.springframework.beans.factory.enter code hereBeanCreationException:无法自动装配字段:private java.lang.String com.titlefeed.config.db.DbConfigJPA.databaseUrl; 嵌套异常是java.lang.IllegalArgumentException:无法解析字符串值"$ {spring.data.postgres.uri}"中的占位符spring.data.postgres.uri'

这意味着Tomcat服务器/春心不是加载应用程序,dev.yml,因为它包含的属性:spring.data.postgres.uri

所以我尝试了以下两种解决方案

1. 添加-Dspring.profiles.active=dev到tomcat/bin/catalina.sh中的JAVA_OPTS
2. 添加spring.profiles.active=dev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:

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.data.postgres.uri' in string value "${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:

无法识别的选项: - spring.profiles.active = dev错误:无法创建Java虚拟机."

编辑3: 修改application.yml以包含以下属性

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

但是我在日志中得到以下异常:

有两种方法可以将spring概要文件args传递到Tomcat 8中。

1.将其设置为环境变量

Tomcat允许您在启动过程中设置CATALINA_HOME/setenv.sh或CATALINA_BASE/setenv.sh调用的环境配置。

setenv.sh:
export SPRING_PROFILES_ACTIVE=dev

您可能还想创建一个src/main/resources/banner.txt包含以下内容的代码：

active profiles     :: ${spring.profiles.active}

它在您的IDE中不起作用（它会从jar / war的MANIFEST.MF文件中读取，如果您正常编译则不会获得该文件），但是在您关心的环境中它非常方便-一切都取决于您当地环境！

2.将其添加到执行类之前的启动脚本/命令中

我修改了CATALINA_HOME/catalina.sh添加一个声明的变量：

SPRING_PROFILE="dev"

并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。但这有效！如果您确实有确切的复制步骤，建议的方法可以随时发布答案，如果可行，我会接受。
