Question

我在Spring Boot 2.2.0.M4 Java 14 Gradle项目中创建了一个新应用：当我添加application.properties文件

    server.port=9001

一切正常。

    Tomcat initialized with port(s): 9001 (http)

当我将module-info.java文件添加到项目中时：

module demo.main {
       requires java.persistence;
       requires static lombok;
       requires java.validation;
       requires org.hibernate.validator;
       requires java.sql;
       requires spring.boot;
       requires java.xml.bind;
       requires net.bytebuddy;
       requires com.fasterxml.classmate;
       requires spring.boot.starter;
       requires spring.boot.autoconfigure;

       opens org.demo
}

应用程序从端口8080启动：

    Tomcat initialized with port(s): 8080 (http)

不会读取整个application.properties文件并将其应用于项目。

当我从项目中删除module-info.java文件时，一切开始正常运行。

build.gradle in root folder
module-info.java file in root/src/main/java
application.properties file in root/src/main/resources

如果我添加：

@PropertySources(
    @PropertySource("classpath:application.properties")
)

顶部：

public class PortalApplication {

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

}

在没有module-info.java文件的项目中，一切正常：

Tomcat initialized with port(s): 9001 (http)

当我将相同的代码添加到带有module-info.java文件的项目中时：

2019-07-19 12:15:29.329  INFO 32502 --- [           main] o.o.portalapp.portal.PortalApplication   : Starting PortalApplication on AMDC2024 with PID 32502 (/home/d.mizyn/portal/out/production/classes started by d.mizyn in /home/d.mizyn/portal)

    at spring.context@5.2.0.M3/org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:184) ~[spring-context-5.2.0.M3.jar:na]

我尝试添加：

requires java.transaction;

在我的module-info.java文件中，该问题的含义如下：

findResource("") returning null when module-info.java is present, why is that?

没有帮助。

所以，我的问题是：如何在不使用命令行参数的情况下更改模块化项目中的server.port：

java -jar demo.jar --server.port=9001

[解决方案] 将application.properties文件移至root / config文件夹
