所有已实现的接口:

org.springframework.objenesis.Objenesis

public class SpringObjenesis
extends Object
implements org.springframework.objenesis.Objenesis

Spring-specific variant of ObjenesisStd / ObjenesisBase, providing a cache based on Class keys instead of class names, and allowing for selective use of the cache.

IGNORE_OBJENESIS_PROPERTY_NAME

public static final String IGNORE_OBJENESIS_PROPERTY_NAME

System property that instructs Spring to ignore Objenesis, not even attempting to use it. Setting this flag to "true" is equivalent to letting Spring find out that Objenesis isn't working at runtime, triggering the fallback code path immediately: Most importantly, this means that all CGLIB AOP proxies will be created through regular instantiation via a default constructor.

构造器详细资料

SpringObjenesis

public SpringObjenesis()

Create a new SpringObjenesis instance with the standard instantiator strategy.

SpringObjenesis

public SpringObjenesis(org.springframework.objenesis.strategy.InstantiatorStrategy strategy)

Create a new SpringObjenesis instance with the given standard instantiator strategy.

参数:

strategy - the instantiator strategy to use

方法详细资料

isWorthTrying

public boolean isWorthTrying()

Return whether this Objenesis instance is worth trying for instance creation, i.e. whether it hasn't been used yet or is known to work.

If the configured Objenesis instantiator strategy has been identified to not work on the current JVM at all or if the "spring.objenesis.ignore" property has been set to "true", this method returns false.

newInstance

public <T> T newInstance(Class<T> clazz,
                         boolean useCache)

Create a new instance of the given class via Objenesis.

参数:

clazz - the class to create an instance of

useCache - whether to use the instantiator cache (typically true but can be set to false e.g. for reloadable classes)

返回:

the new instance (never null)

抛出:

ObjenesisException - if instance creation failed

newInstance

public <T> T newInstance(Class<T> clazz)

指定者:

newInstance 在接口中 org.springframework.objenesis.Objenesis

getInstantiatorOf

public <T> org.springframework.objenesis.instantiator.ObjectInstantiator<T> getInstantiatorOf(Class<T> clazz)

指定者:

getInstantiatorOf 在接口中 org.springframework.objenesis.Objenesis

newInstantiatorOf

protected <T> org.springframework.objenesis.instantiator.ObjectInstantiator<T> newInstantiatorOf(Class<T> clazz)
