SpringApplication (spring-boot 2.0.4.RELEASE)

java.lang.Object
- org.springframework.boot.SpringApplication

```
public class SpringApplication
extends Object
```
Class that can be used to bootstrap and launch a Spring application from a Java main method. By default class will perform the following steps to bootstrap your application:
- Create an appropriate ApplicationContext instance (depending on your classpath)
- Register a CommandLinePropertySource to expose command line arguments as Spring properties
- Refresh the application context, loading all singleton beans
- Trigger any CommandLineRunner beans
In most circumstances the static run(Class, String[]) method can be called directly from your main method to bootstrap your application:
```
 @Configuration
 @EnableAutoConfiguration
 public class MyApplication  {

   // ... Bean definitions

   public static void main(String[] args) throws Exception {
     SpringApplication.run(MyApplication.class, args);
   }
 }
 
```
For more advanced configuration a SpringApplication instance can be created and customized before being run:
```
 public static void main(String[] args) throws Exception {
   SpringApplication application = new SpringApplication(MyApplication.class);
   // ... customize application settings here
   application.run(args)
 }
 
```
SpringApplications can read beans from a variety of different sources. It is generally recommended that a single @Configuration class is used to bootstrap your application, however, you may also set sources from:
- The fully qualified class name to be loaded by AnnotatedBeanDefinitionReader
- The location of an XML resource to be loaded by XmlBeanDefinitionReader, or a groovy script to be loaded by GroovyBeanDefinitionReader
- The name of a package to be scanned by ClassPathBeanDefinitionScanner
Configuration properties are also bound to the SpringApplication. This makes it possible to set SpringApplication properties dynamically, like additional sources ("spring.main.sources" - a CSV list) the flag to indicate a web environment ("spring.main.web-application-type=none") or the flag to switch off the banner ("spring.main.banner-mode=off").

    Returns read-only ordered Set of the ApplicationContextInitializers that will be applied to the Spring ApplicationContext.
    
    Returns:
    
    the initializers
  - setListeners
```
public void setListeners(Collection<? extends org.springframework.context.ApplicationListener<?>> listeners)
```
    Sets the ApplicationListeners that will be applied to the SpringApplication and registered with the ApplicationContext.
    
    Parameters:
    
    listeners - the listeners to set
  - addListeners
```
public void addListeners(org.springframework.context.ApplicationListener<?>... listeners)
```
    Add ApplicationListeners to be applied to the SpringApplication and registered with the ApplicationContext.
    
    Parameters:
    
    listeners - the listeners to add
  - getListeners
```
public Set<org.springframework.context.ApplicationListener<?>> getListeners()
```
    Returns read-only ordered Set of the ApplicationListeners that will be applied to the SpringApplication and registered with the ApplicationContext .
    
    Returns:
    
    the listeners
  - run
```
public static org.springframework.context.ConfigurableApplicationContext run(Class<?> primarySource,
                                                                             String... args)
```
    Static helper that can be used to run a SpringApplication from the specified source using default settings.
    
    Parameters:
    
    primarySource - the primary source to load
    
    args - the application arguments (usually passed from a Java main method)
    
    Returns:
    
    the running ApplicationContext
  - run
```
public static org.springframework.context.ConfigurableApplicationContext run(Class<?>[] primarySources,
                                                                             String[] args)
```
    Static helper that can be used to run a SpringApplication from the specified sources using default settings and user supplied arguments.
    
    Parameters:
    
    primarySources - the primary sources to load
    
    args - the application arguments (usually passed from a Java main method)
    
    Returns:
    
    the running ApplicationContext
  - main
```
public static void main(String[] args)
                 throws Exception
```
    A basic main that can be used to launch an application. This method is useful when application sources are defined via a --spring.main.sources command line argument.
    Most developers will want to define their own main method and call the run method instead.
    
    Parameters:
    
    args - command line arguments
    
    Throws:
    
    Exception - if the application cannot be started
    
    See Also:
    
    run(Class[], String[]), run(Class, String...)
  - exit
```
public static int exit(org.springframework.context.ApplicationContext context,
                       ExitCodeGenerator... exitCodeGenerators)
```
    Static helper that can be used to exit a SpringApplication and obtain a code indicating success (0) or otherwise. Does not throw exceptions but should print stack traces of any encountered. Applies the specified ExitCodeGenerator in addition to any Spring beans that implement ExitCodeGenerator. In the case of multiple exit codes the highest value will be used (or if all values are negative, the lowest value will be used)
    
    Parameters:
    
    context - the context to close if possible
    
    exitCodeGenerators - exist code generators
    
    Returns:
    
    the outcome (0 if successful)
