@PropertySource没有在使用传统tomcat war部署的spring启动应用程序中获取-Java 学习之路

我有一个传统的war启动应用程序部署到tomcat 8.尽管我已经定义了@PropertySources注释，但似乎找不到在@PropertySources中指定的目录中给出的属性文件中定义的属性 . 我修改了一个spring boot web示例项目，可以复制问题 . 在下面的示例中，调用Web控制器的结果始终是“Hello Default，Spring Boot的问候！” . 它永远不会从外部application.properties中获取“name”.property（如果我从类属性文件中完全删除该属性，则部署失败，因为该属性永远不会解析） . 我错过了什么，外部属性似乎没有被拿起？

我的应用类：

@SpringBootApplication
@Profile("dev")
@PropertySource(value = "file:/usr/local/tomcat/config/")
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder builder) {
        return builder.profiles("dev").sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

网络控制器：

@RestController
public class HelloController {

    @Value("${name}")
    private String name;

    @RequestMapping("/")
    public String index() {
        return "Hello " +name+ ", Greetings from Spring Boot!";
    }
}

SRC /主/资源/ application.properties：

debug=true
logging.level.org.springframework.boot.context=DEBUG
logging.level.org.springframework.boot.env=DEBUG
logging.level.org.springframework.web=DEBUG
name=Default

/ usr / local / tomcat / config中的外部application.properties

name=Default

使用传统的tomcat war部署时，我建议使用相对于类路径的文件夹路径，而不是绝对路径 .

在配置Spring Boot应用程序时，您需要在开头定义变量 spring.config.location ：

public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder springApplicationBuilder) {
        return springApplicationBuilder
                .sources(Application.class)
                .properties(getProperties());
    }

    public static void main(String[] args) {

        SpringApplicationBuilder springApplicationBuilder = new SpringApplicationBuilder(Application.class)
                .sources(Application.class)
                .properties(getProperties())
                .run(args);
    }

   static Properties getProperties() {
      Properties props = new Properties();
      props.put("spring.config.location", "classpath:myapp1/");
      return props;
   }
