pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>java code
@SpringBootApplication()
public class TestApp {
public static void main(String[] args) {
SpringApplication.run(TestApp.class, args);
}
}
application.properties
management.info.env.enabled=true2. 显示Maven相关的值
在application.properties文件里，加入下面key-value属性
[email protected]@
[email protected]@
[email protected]@
[email protected]@
[email protected]@
[email protected]@
management.info.env.enabled=true如果您不使用starter parent，则需要在pom.xml的<build/>元素中包含以下元素
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>执行maven clean compile -DskipTests命令后，你会发现application.properties里定义的maven相关的占位符已经被替换了。
结果如下：
info.app.name=test_project
info.app.description=Parent pom providing dependency and plugin management for applications built with Maven
info.app.version=1.0-SNAPSHOT
info.app.encoding=UTF-8
info.app.java.source=1.8.0_321
info.app.java.target=1.8.0_321启动spring-boot的项目，访问actuator/info节点，就可以看到下面的信息了。
{
"app" : {
"name" : "test_project",
"description" : "Parent pom providing dependency and plugin management for applications built with Maven",
"version" : "1.0-SNAPSHOT",
"encoding" : "UTF-8",
"java" : {
"source" : "1.8.0_321",
"target" : "1.8.0_321"
}
},
}3. 显示git 相关的值
<plugin>
<groupId>pl.project13.maven</groupId>
<artifactId>git-commit-id-plugin</artifactId>
<version>2.1.4</version>
</plugin>执行maven clean install-DskipTests 后，你会发现在你的classes目录下面有个git.properties文件生成。
git.branch=dev
git.commit.id=xxx
git.commit.user.name=xxx
......启动spring-boot的项目，访问actuator/info节点，就可以看到下面的信息了。
{
"git" : {
"commit" : {
"time" : "2023-04-06T12:16:17Z",
"id" : "e3dd1233"
},
"branch" : "dev"
}
}一起显示maven和git 的信息
{
"app" : {
"name" : "test_project",
"description" : "Parent pom providing dependency and plugin management for applications built with Maven",
"version" : "1.0-SNAPSHOT",
"encoding" : "UTF-8",
"java" : {
"source" : "1.8.0_321",
"target" : "1.8.0_321"
}
},
"git" : {
"commit" : {
"time" : "2023-04-06T12:16:17Z",
"id" : "e3dd1233"
},
"branch" : "dev"
}
}4. 加build info
添加有用的构建信息有助于快速识别构建工件名称、版本、创建时间等。它可以派上用场来检查团队是否部署了应用程序的相关版本。 Spring Boot 允许使用 Maven 或 Gradle 构建插件轻松添加它。
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.6.4</version>
<executions>
<execution>
<goals>
<goal>build-info</goal>
</goals>
</execution>
</executions>
</plugin>编译完代码后会生成target/classes/META-INF/build-info.properties文件
内容如下
build.artifact=spring-boot-build-info
build.group=io.reflectoring
build.name=spring-boot-build-info
build.time=2022-03-06T05\:53\:45.236Z
build.version=0.0.1-SNAPSHOT还可以使用 additionalProperties 属性将自定义属性添加到此列表：
<execution>
<goals>
<goal>build-info</goal>
</goals>
<configuration>
<additionalProperties>
<custom.key1>value1</custom.key1>
<custom.key2>value2</custom.key2>
</additionalProperties>
</configuration>
</execution>如果我们现在运行应用程序并在浏览器中打开 http://localhost:8080/actuator/info 端点，我们将看到类似于以下的响应：
{
"build": {
"custom": {
"key2": "value2",
"key1": "value1"
},
"version": "0.0.1-SNAPSHOT",
"artifact": "spring-boot-build-info",
"name": "spring-boot-build-info",
"time": "2022-03-06T06:34:30.306Z",
"group": "io.reflectoring"
}
}如果要排除任何可能使用 excludeInfoProperties 配置的属性。让我们看看如何排除工件属性：
<configuration>
<excludeInfoProperties>
<infoProperty>artifact</infoProperty>
</excludeInfoProperties>
</configuration>Please refer to the official Spring Boot documentation to know more.
