1、读取pom中的值

1.1、pom.xml

<properties>
    <pom.var.name>pomValue</pom.var.name>
</properties>




<build>
    <!-- 定义资源目录 -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <!--filtering 这个配置的意思是过滤上面指定属性文件中的占位符，占位符是${变量名称}这样的形式，
						  maven会自动读取配置文件，然后解析其中的占位符，使用上面pom文件中定义的属性进行替换 -->
            <filtering>true</filtering>
        </resource>
        <resource>
            <directory>${profiles.active}</directory>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>

        
        
        
        <plugins>
            <plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <encoding>utf-8</encoding>
                    <useDefaultDelimiters>true</useDefaultDelimiters>
                </configuration>
            </plugin>
        </plugins>
        </build>

1.2、demo.properties

image-20200724151323802

demo.name=healerjean
demo.age=12
demo.pomVal=pomValue
demo.version=1.0.0-SNAPSHOT

1.3、使用

@Configuration
@Slf4j
public class Customonfiguration implements EnvironmentAware {

    private Environment environment;

    @Override
    public void setEnvironment(Environment environment) {
        this.environment = environment;
    }


    @PostConstruct
    public void init() {
        log.info("demo.name ==> {}" , environment.getProperty("demo.name"));
        log.info("demo.version ==> {}" , environment.getProperty("demo.version"));
    }

}
