从spring-boot-starter-parent继承依赖项的Maven pom.xml不起作用

Question

server.port=8761

src/main/resources/application.yml

server:
 port: 1112

来自Spring文档：

创建一个名为application.yml的文件并将其放在类路径的根目录中，还将snakeyaml添加到依赖项中（如果使用spring-boot-starter，Maven坐标org.yaml：snakeyaml已经包含在内）。

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

Overriding managed version 1.17 for snakeyaml

在这个问题上有人能帮我吗？

Answer 1

My org.yaml：SnakeyAML来自spring-boot-starter-web（mvn dependency：tree命令）

[INFO] +- org.springframework.boot:spring-boot-starter-web:jar:1.5.1.RELEASE:compile
[INFO] |  +- org.springframework.boot:spring-boot-starter:jar:1.5.1.RELEASE:compile

[INFO] |  |  \- org.yaml:snakeyaml:jar:1.17:runtime

下面是依赖关系

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>1.5.1.RELEASE</version>
</dependency>

可能是在其他的Spring引导启动模块中包含Spring引导启动程序（spring-boot-starter）。

<dependency>
    <groupId>org.yaml</groupId>
    <artifactId>snakeyaml</artifactId>
    <version>1.19</version>
</dependency>
