1、maven

1.1、激活测试目录local

      <properties>
                <profiles.active>src/profiles/local</profiles.active>
            </properties>

<profiles>
        <profile>
            <!-- 本地开发环境 -->
            <id>local</id>
            <properties>
                <profiles.active>src/profiles/local</profiles.active>
            </properties>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>
        <profile>
            <!-- 开发环境 -->
            <id>dev</id>
            <properties>
                <profiles.active>src/profiles/dev</profiles.active>
            </properties>
            <activation>
                <property>
                    <name>dev</name>
                    <value>true</value>
                </property>
            </activation>
        </profile>
        <profile>
            <!-- 生产环境 -->
            <id>product</id>
            <properties>
                <profiles.active>src/profiles/product</profiles.active>
            </properties>
            <activation>
                <property>
                    <name>product</name>
                    <value>true</value>
                </property>
            </activation>
        </profile>
    </profiles>

1.2、添加profiles作为resource目录

<build>
    <!-- 定义资源目录 -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <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>
    </resources>

2、我们可以选中本地

3、使用Properties测试

3.1、resource目录下创建resource.properties


## properties 取值 ##
profile.name=resource.name
profile.age=resource.age

3.2、激活的profile目录下创建profile.properties


## properties 取值 ##
profile.name=profile.name
profile.age=profile.age

package com.hlj.utils;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class PropertiesUtil {
	public static Properties properties = new Properties();

	public static String getProperty(String key) {
		return properties.getProperty(key) == null ? "" : properties.get(key).toString();
	}

	static {
			String profile = System.getProperty("spring.profiles.active");
		    System.out.println(profile);

			String[]  props = new String[] {"profile.properties", "resource.properties" };
			for(String prop:props){
				InputStream inputStream = PropertiesUtil.class.getClassLoader().getResourceAsStream(prop);
				if (inputStream != null) {
					Properties propertiest = new Properties();
					try {
						propertiest.load(inputStream);
						properties.putAll(propertiest);

					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}
	}
}

3.3、测试

    @ApiOperation(value = "获取properties",notes = "获取properties",
            consumes = MediaType.MULTIPART_FORM_DATA_VALUE,
            produces = MediaType.APPLICATION_JSON_VALUE,
            response = ResponseBean.class)
    @ApiImplicitParams({
            @ApiImplicitParam(name = "name", value = "参数", required =false,paramType = "query", dataType = "string")
    })
    @GetMapping("get")
    @ResponseBody
    public ResponseBean get(String name){
        try {
            System.out.println(PropertiesUtil.getProperty(name));
            return ResponseBean.buildSuccess(PropertiesUtil.getProperty(name));
        } catch (AppException e) {
            log.error(e.getMessage(),e);
            return ResponseBean.buildFailure(e.getCode(),e.getMessage());
        } catch (Exception e) {
            log.error(e.getMessage(),e);
            return ResponseBean.buildFailure(e.getMessage());
        }
    }
