question可以添加多个tomcat连接器并将它们分别绑定到单独的控制器。
安迪·威尔金森(Andy Wilkinson)好的回答的实质在这里:
public static void main(String[] args) {
SpringApplicationBuilder parentBuilder
= new SpringApplicationBuilder(ApplicationConfiguration.class);
parentBuilder.child(ServiceOneConfiguration.class)
.properties("server.port:8080").run(args);
parentBuilder.child(ServiceTwoConfiguration.class)
.properties("server.port:8081").run(args);
}
我想再继续问一个问题:
是否有一种方法可以使每个子应用程序上下文在支持所有标准spring-boot功能(例如配置文件后缀文件名等)的情况下读取某些特定于子应用程序的属性。
具有三个单独的属性文件:
application.properties
child1.properties
child2.properties
并且能够为每个上下文设置一个文件。
但是对我来说重要的是,它们必须支持所有的弹簧靴魔术。例如,如果我激活新的配置文件(例如传递命令行参数--spring.profiles.active=dev
),那么不仅应该自动加载这三个文件(每个上下文一个),还应该加载另一组文件(如果存在)自动:
application-dev.properties
child1-dev.properties
child2-dev.properties
当然,应该在标准spring-boot支持的路径中以定义的顺序等搜索这些文件。
是否有可能带有一些编码的框?
只有一个application.properties
文件(支持配置文件等),但是以某种方式将前缀属性映射到子上下文的未前缀属性。
示例:
child1.server.port=8081
child1.foo=bar
child2.server.port=8082
child2.foo=baz
第一个子上下文应该看到这些属性,就像它们只是:
server.port=8081
foo=bar
第二个子上下文应该看到这些属性,就像它们只是:
server.port=8082
foo=baz
因此,标准的spring-boot的自动配置将起作用并正确设置了tomcat的端口等。
我不是在寻找特定的方法(但是,如果您问我,我倾向于第二种方法),但是任何开箱即用的工作或可以用最少的方式进行的工作都可以满足我。
答案 0 :(得分:2)
您可以使用spring.config.name
实现第一个建议:
public static void main(String[] args) {
SpringApplicationBuilder parentBuilder =
new SpringApplicationBuilder(ParentApplication.class)
.web(WebApplicationType.NONE);
parentBuilder.run(args);
parentBuilder.child(ServiceOneConfiguration.class)
.properties("spring.config.name=child1").run(args);
parentBuilder.child(ServiceTwoConfiguration.class)
.properties("spring.config.name=child2").run(args);
}
然后可以使用child1{-profile}.properties
和child2{-profile}.properties
分别配置服务一和服务二。
例如,如果server.port=8081
中的child1.properties
和server.port=8082
中的child2.properties
,则在启动使用自动配置的应用程序时,应该会看到类似于以下的输出两个子服务,并且依赖于spring-boot-starter-web
