Spring Boot应用程序未在

标签： java spring maven spring-boot

我正在使用Spring Boot应用程序，正在尝试启用外部application.properties，以便在从控制台运行jar时可以注入这些属性。

我的Configuration类中有此注释     @PropertySource（value =“ file：$ {env.properties.location} /application.properties”）

其余的配置类：

@Component
@Configuration
@EnableCassandraRepositories(basePackages = "uk.co.dashboard.repository")
@PropertySource(value="file:${env.properties.location}/application.properties")
public class CassandraConfiguration {

@Value("${cassandra.contactpoints}")
private String[] cassandraContactPoint;

@Value("${cassandra.port}")
private Integer cassandraPort;

@Value("${cassandra.keyspace}")
private String keyspaceName;



@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

@Bean
public MappingManager mappingManager(@Qualifier("session") Session session) {
    return new MappingManager(session);
}

@Bean
public Session session() {
    Cluster cluster = connectToCluster();
    Session session = cluster.connect(keyspaceName);
    return session;
}

@Bean
public DataRepository dataRepository(MappingManager mappingManager){
    return mappingManager.createAccessor(DataRepository.class);
}


public Cluster connectToCluster() {
    QueryOptions queryOptions = new QueryOptions();
    queryOptions.setConsistencyLevel(ConsistencyLevel.QUORUM);
    Cluster cluster = Cluster.builder()
            .addContactPoints(cassandraContactPoint)
            .withPort(cassandraPort)
            .withQueryOptions(queryOptions)
            .build();
    return cluster;
}

protected String getKeyspaceName() {
    return keyspaceName;
}

@Bean
public BasedataService basedataService(){
    return new BasedataService();
}

我正在终端中运行此命令

java -jar basedata-dashboard-1.0.0-SNAPSHOT.jar -Denv.properties.location ='/ home / Desktop'

在我的桌面上，是一个名为application.properties的文件，其中包含配置详细信息。但是，当运行上面的命令时，我得到了：

现在，当我在工作目录中有一个application.properties的本地副本时，我的应用程序就可以工作，但是出于意图的考虑，这是不可行的，我需要能够通过控制台对应用程序执行ping操作，并在出现以下情况时提供application.properties文件我这样做是因为这些变量将发生变化和/或应用将用于不同的目的。

我一直在网上寻找很多时间，但是我确实很困惑，我觉得我读过的大多数东西都告诉我它设置正确，但是我不知道为什么它不起作用

我要包含的最后一件事是pom：

在-jar选项之前提供JAVA_OPTS时，java的命令行参数运行良好。

我最初遇到过类似的问题，并且能够通过在-jar选项之前更改系统属性来解决此问题。

请尝试以下命令行选项：

java -Denv.properties.location='/home/Desktop' -jar basedata-dashboard-1.0.0-SNAPSHOT.jar
