Maven SpringBoot项目JAR无法读取application.properties问题求助

Spring Boot JAR运行时无法解析secure.url配置，但IDE直接运行正常

本地IDE直接运行主类时项目正常启动，但构建成JAR包运行时抛出配置解析错误：

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'secure.url' in value "${secure.url}"

项目此前运行正常，近期突发该问题。

排查与解决步骤

1. 验证JAR包内的配置文件

解压JAR包检查配置是否被正确打包：

unzip client-0.0.1-SNAPSHOT.jar -d temp-check

进入temp-check/BOOT-INF/classes/目录，确认application.properties存在且包含secure.url配置。如果缺失，说明构建时资源未被打包。

2. 修复Maven资源打包配置

确保application.properties放在src/main/resources目录下，若pom.xml未明确资源配置，添加以下内容到<build>节点：

<resources>
    <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
    </resource>
</resources>

3. 重新构建JAR

使用标准Spring Boot构建命令，确保资源被正确打包：

mvn clean install

4. 修正Bean初始化顺序

原代码在构造方法中直接使用字段注入的配置值，可能因初始化顺序导致值未被注入。改为构造方法注入所有依赖：

@Component
public class PotentiometerHandler {

    private final String secureApiUrl;
    private final String potApi;
    private final String systemApi;
    private final int ladc;
    private final int lsys;
    private final int buzz;
    private final WebClient webClient;

    public PotentiometerHandler(WebClient.Builder webClientBuilder,
                                @Value("${secure.url}") String secureApiUrl,
                                @Value("${pot.api}") String potApi,
                                @Value("${system.api}") String systemApi,
                                @Value("${system.settings.ladc}") int ladc,
                                @Value("${system.settings.lsys}") int lsys,
                                @Value("${system.settings.buzz}") int buzz) {
        this.secureApiUrl = secureApiUrl;
        this.potApi = potApi;
        this.systemApi = systemApi;
        this.ladc = ladc;
        this.lsys = lsys;
        this.buzz = buzz;
        this.webClient = webClientBuilder.baseUrl(secureApiUrl).build();
    }

    // 其他业务代码
}

5. 检查环境配置冲突

如果使用多环境配置，运行JAR时指定正确的环境：

java -jar client-0.0.1-SNAPSHOT.jar --spring.profiles.active=dev

确保激活的配置文件包含secure.url项。
