org.springframework.context.support.LiveBeansView

所有已实现的接口:

org.springframework.beans.factory.Aware, ApplicationContextAware, LiveBeansViewMBean

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 local ApplicationContext (with a local LiveBeansView 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.

从以下版本开始:

3.2

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 after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.

指定者:

setApplicationContext 在接口中 ApplicationContextAware

参数:

applicationContext - the ApplicationContext object to be used by this object

getSnapshotAsJson

public String getSnapshotAsJson()

Generate a JSON snapshot of current beans and their dependencies, finding all active ApplicationContexts through findApplicationContexts(), then delegating to generateJson(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,
                                 org.springframework.beans.factory.config.BeanDefinition bd,
                                 org.springframework.beans.factory.config.ConfigurableBeanFactory bf)

Determine whether the specified bean is eligible for inclusion in the LiveBeansView JSON snapshot.

参数:

beanName - the name of the bean

bd - the corresponding bean definition

bf - the containing bean factory

返回:

true if the bean is to be included; false otherwise

getEscapedResourceDescription

@Nullable
protected String getEscapedResourceDescription(org.springframework.beans.factory.config.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
