Spring项目中使用 getBean()+PropertySourcesPlaceholderConfigurer 踩坑记录

在进入正题之前，首先简单介绍一下标题中提到的两个Spring中的概念，以及给出一个PropertySourcesPlaceholderConfigurer的入门使用场景
概念介绍：

org.springframework.context.support.AbstractApplicationContext#getBean(java.lang.Class<T>)
简而言之：这个方法可以通过类名，从spring容器中获取相对应的实例。
==============================================================================
org.springframework.context.support.PropertySourcesPlaceholderConfigurer
简而言之：这个工具类用来解析BeanDefinition的属性中还有@Value注解中的占位符 ${...}
==============================================================================
org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor#postProcessBeanDefinitionRegistry
简而言之：这个工具类可以用来自定义BeanDenifition并将其交给spring容器管理
==============================================================================
以下附上 spring-context-5.2.8.RELEASE 中的 javadoc

/**
* Return the bean instance that uniquely matches the given object type, if any.
* <p>This method goes into {@link ListableBeanFactory} by-type lookup territory
* but may also be translated into a conventional by-name lookup based on the name
* of the given type. For more extensive retrieval operations across sets of beans,
* use {@link ListableBeanFactory} and/or {@link BeanFactoryUtils}.
* @param requiredType type the bean must match; can be an interface or superclass
* @return an instance of the single bean matching the required type
* @throws NoSuchBeanDefinitionException if no bean of the given type was found
* @throws NoUniqueBeanDefinitionException if more than one bean of the given type was found
* @throws BeansException if the bean could not be created
* @since 3.0
* @see ListableBeanFactory
*/
<T> T getBean(Class<T> requiredType) throws BeansException;
==============================================================================
/**
 * Specialization of {@link PlaceholderConfigurerSupport} that resolves ${...} placeholders
 * within bean definition property values and {@code @Value} annotations against the current
 * Spring {@link Environment} and its set of {@link PropertySources}.
 *
 * <p>This class is designed as a general replacement for {@code PropertyPlaceholderConfigurer}.
 * It is used by default to support the {@code property-placeholder} element in working against
 * the spring-context-3.1 or higher XSD; whereas, spring-context versions &lt;= 3.0 default to
 * {@code PropertyPlaceholderConfigurer} to ensure backward compatibility. See the spring-context
 * XSD documentation for complete details.
 *
 * <p>Any local properties (e.g. those added via {@link #setProperties}, {@link #setLocations}
 * et al.) are added as a {@code PropertySource}. Search precedence of local properties is
 * based on the value of the {@link #setLocalOverride localOverride} property, which is by
 * default {@code false} meaning that local properties are to be searched last, after all
 * environment property sources.
 *
 * <p>See {@link org.springframework.core.env.ConfigurableEnvironment} and related javadocs
 * for details on manipulating environment property sources.

}

PropertySourcesPlaceholderConfigurer的入门使用场景：
spring.xml部分配置：

<context:property-placeholder location="classpath:application.properties" />

<bean id="propertiesBean" class="org.example.alvin.springexamples.bean.PropertiesBean">
  <property name="name" value="${propertiesBean.name}" />
  <property name="password" value="${propertiesBean.password}" />
</bean>

application.properties部分配置：

propertiesBean.name=test
propertiesBean.password=123456

下面进入正题。
基于入门使用场景以及结合javadoc中的描述，我们可以想象以下一个场景：
现有以下class PlaceHolderBean1.该class并没有@Component注解，在application.properties中有如下配置，如何实例化配置文件中声明的类实例并将其加入spring容器中？
java类声明：

public class PlaceHolderBean1 {}

application.properties部分配置：

placeHolderBeanClasses=${placeHolderBeanClass1}
placeHolderBeanClass1=org.example.alvin.springexamples.bean.PlaceHolderBean1

java实现：

@Component
public class BeanPos implements BeanDefinitionRegistryPostProcessor {

  private final Logger logger = LogManager.getLogger(BeanPos.class);

  @Override
  public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry) throws BeansException {
    logger.info("Invoked into postProcessBeanDefinitionRegistry, params: {}", registry);

    // 配置文件 + 占位符 实例化 bean
    logger.info("Start initializing custom bean...");
    try {
      Properties properties = PropertiesLoaderUtils.loadAllProperties("application.properties", ClassUtils.getDefaultClassLoader());
      String placeHolderBeanClasses = properties.getProperty("placeHolderBeanClasses");
      String[] classNames = placeHolderBeanClasses.split(",");
      for (String className : classNames) {
        BeanDefinition beanDefinition = new GenericBeanDefinition();
        beanDefinition.setBeanClassName(className);
        String beanName = BeanDefinitionReaderUtils.generateBeanName(beanDefinition, registry);
        registry.registerBeanDefinition(beanName, beanDefinition);
      }
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

  @Override
  public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
    logger.info("Invoked into postProcessBeanFactory, params: {}", beanFactory);
  }
}

经过简单的测试，结果正如预期那样成功将PlaceHolderBean1实例加入了spring容器。

@Test
void test8() {
  ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml");
  PlaceHolderBean1 bean = applicationContext.getBean(PlaceHolderBean1.class);
  Assertions.assertNotNull(bean);
}

下面是重点：
一个偶然的机会，我在BeanPos的postProcessBeanFactory方法中加入了一段代码，这个代码直接导致了占位符解析错误，测试代码报错。

@Override
public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
  logger.info("Invoked into postProcessBeanFactory, params: {}", beanFactory);
  PropertySourcesPlaceholderConfigurer placeholderConfigurer = beanFactory.getBean(PropertySourcesPlaceholderConfigurer.class);
  placeholderConfigurer.setLocalOverride(true);
}

经过漫长的debug，最终发现 beanFactory.getBean(PropertySourcesPlaceholderConfigurer.class) 直接导致了错误结果。
根本原因：
postProcessBeanDefinitionRegistry()方法会先于postProcessBeanFactory()方法执行，在前者执行过程当中，会将BeanClassName为${placeHolderBeanClass1}的BeanDenifition加入spring容器中。当后者执行时 beanFactory.getBean(PropertySourcesPlaceholderConfigurer.class) 会在spring容器加载过程当中提前触发PropertySourcesPlaceholderConfigurer类型的实例化。在实例化时，spring会遍历BeanDefinitionNames容器中的所有beanName，逐个判断是否是FactoryBean。此时，spring会为每个beanName建立和BeanDefinition的映射，而${placeHolderBeanClass1}在没有经过 org.springframework.context.support.PropertySourcesPlaceholderConfigurer#postProcessBeanFactory 的解析之前，是无法建立映射的，最终在发现allowEagerInit属性为true的情况下，doGetBeanNamesForType中的catch语句不会再吞掉异常，而是会直接throw给spring容器，最终导致测试失败退出
