ServletContextLiveBeansView
public class LiveBeansView extends Object implements LiveBeansViewMBean, ApplicationContextAware
Adapter for live beans view exposure, building a snapshot of current beans and their dependencies from either a localApplicationContext
(with a localLiveBeansView
bean definition) or all registered ApplicationContexts (driven by the "spring.liveBeansView.mbeanDomain" environment property).Note: This feature is still in beta and primarily designed for use with Spring Tool Suite 3.1 and higher.

setApplicationContext
public void setApplicationContext(ApplicationContext applicationContext)
从接口复制的说明:ApplicationContextAware
Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.Invoked after population of normal bean properties but before an init callback such as
InitializingBean.afterPropertiesSet()
or a custom init-method. Invoked afterResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader)
,ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher)
andMessageSourceAware
, if applicable.- 指定者:
setApplicationContext
在接口中ApplicationContextAware
- 参数:
applicationContext
- the ApplicationContext object to be used by this object- 另请参阅:
BeanInitializationException
getSnapshotAsJson
public String getSnapshotAsJson()
Generate a JSON snapshot of current beans and their dependencies, finding all active ApplicationContexts throughfindApplicationContexts()
, then delegating togenerateJson(java.util.Set)
.- 指定者:
getSnapshotAsJson
在接口中LiveBeansViewMBean
findApplicationContexts
protected Set<ConfigurableApplicationContext> findApplicationContexts()
Find all applicable ApplicationContexts for the current application.Called if no specific ApplicationContext has been set for this LiveBeansView.
- 返回:
- the set of ApplicationContexts
generateJson
protected String generateJson(Set<ConfigurableApplicationContext> contexts)
Actually generate a JSON snapshot of the beans in the given ApplicationContexts.This implementation doesn't use any JSON parsing libraries in order to avoid third-party library dependencies. It produces an array of context description objects, each containing a context and parent attribute as well as a beans attribute with nested bean description objects. Each bean object contains a bean, scope, type and resource attribute, as well as a dependencies attribute with a nested array of bean names that the present bean depends on.
- 参数:
contexts
- the set of ApplicationContexts- 返回:
- the JSON document
isBeanEligible
protected boolean isBeanEligible(String beanName, BeanDefinition bd, ConfigurableBeanFactory bf)
Determine whether the specified bean is eligible for inclusion in the LiveBeansView JSON snapshot.- 参数:
beanName
- the name of the beanbd
- the corresponding bean definitionbf
- the containing bean factory- 返回:
true
if the bean is to be included;false
otherwise
getEscapedResourceDescription
protected String getEscapedResourceDescription(BeanDefinition bd)
Determine a resource description for the given bean definition and apply basic JSON escaping (backslashes, double quotes) to it.- 参数:
bd
- the bean definition to build the resource description for- 返回:
- the JSON-escaped resource description
