春天：mvn干净的tomcat：运行在命令行上但不是IntelliJ

我有一个Maven控制器春天的web应用程序，它运行良好与mvn clean tomcat:run命令行，但我不能让它与运行/调试配置。我收到一长串自动故障依赖性故障，结束于：春天：mvn干净的tomcat：运行在命令行上但不是IntelliJ

... bean的实例化失败;嵌套异常是 org.springframework.beans.BeanInstantiationException：无法实例化bean类 [com.mycompany.config.DataSourceConfig $$ EnhancerByCGLIB $$ 543b87de]：构造函数抛出异常;嵌套的例外是 java.lang.NumberFormatException：空

这里是有问题的类：

@Configuration 
public class DataSourceConfig { 


    //change PACKAGE_TO_SCAN 
    private static final String PACKAGE_TO_SCAN = "com.mycompany"; 
    private static final int MODE_DEV = 0; 
    private static final int MODE_STG = 1; 
    private static final int MODE_PROD = 2; 


    private Logger log = LoggerFactory.getLogger(this.getClass()); 

    private int environment = Integer.parseInt(System.getenv("ENVIRONMENT")); 

    private String dburl = System.getenv("UMWORKFLOW_DATABASE_URL"); 
    private String dbuser = System.getenv("UMWORKFLOW_DATABASE_USER"); 
    private String dbpass = System.getenv("UMWORKFLOW_DATABASE_PASSWORD"); 



    public DataSourceConfig(){ 

    } 

    @Bean(destroyMethod="close") 
    public ComboPooledDataSource dataSource() throws URISyntaxException, PropertyVetoException { 

     ComboPooledDataSource ds = new ComboPooledDataSource(); 



     ds.setDriverClass("org.postgresql.Driver"); 
     ds.setMinPoolSize(1); 
     ds.setMaxPoolSize(10); 
     ds.setAcquireIncrement(1); 
     ds.setIdleConnectionTestPeriod(300); 
     ds.setMaxStatements(0); 
     ds.setCheckoutTimeout(100); 

     ds.setJdbcUrl(dburl); 
     ds.setUser(dbuser); 
     ds.setPassword(dbpass); 

     return ds; 

    } 

    @Bean 
    public AnnotationSessionFactoryBean sessionFactory() throws URISyntaxException, PropertyVetoException { 

     AnnotationSessionFactoryBean sf = new AnnotationSessionFactoryBean(); 
     sf.setDataSource(dataSource()); 
     String[] packageToScan = new String[1]; 
     packageToScan[0] = PACKAGE_TO_SCAN; 
     sf.setPackagesToScan(packageToScan); 
     Properties hibProp = new Properties(); 
     hibProp.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect"); 


     //modes create, create-drop, update, validate 
     if(environment == MODE_DEV) { 

      hibProp.put("hibernate.hbm2ddl.auto", "update"); 

     } else if (environment == MODE_STG) { 

      hibProp.put("hibernate.hbm2ddl.auto", "update"); 
     } else { 

      hibProp.put("hibernate.hbm2ddl.auto", "update"); 
     } 


     sf.setHibernateProperties(hibProp); 
     return sf; 
    } 

}

系统属性ENVIRONMENT似乎是定制的。

private int environment = Integer.parseInt(System.getenv("ENVIRONMENT"));

所以System.getenv()将返回null并造成IllegalArgumentException。您需要在run/debug配置中设置该属性。
