org.springframework.expression
使用org.springframework.expression的程序包 程序包 说明 org.springframework.context.expression Expression parsing support within a Spring application context.org.springframework.expression Core abstractions behind the Spring Expression Language.org.springframework.expression.common Common utility classes behind the Spring Expression Language.org.springframework.expression.spel SpEL's central implementation package.org.springframework.expression.spel.ast SpEL's abstract syntax tree.org.springframework.expression.spel.standard SpEL's standard parser implementation.org.springframework.expression.spel.support SpEL's default implementations for various core abstractions.org.springframework.context.expression使用的org.springframework.expression中的类 类 说明 AccessException An AccessException is thrown by an accessor if it has an unexpected problem.BeanResolver A bean resolver can be registered with the evaluation context and will kick in for bean references:@myBeanName
and&myBeanName
expressions.EvaluationContext Expressions are executed in an evaluation context.Expression An expression capable of evaluating itself against context objects.ExpressionParser Parses expression strings into compiled expressions that can be evaluated.PropertyAccessor A property accessor is able to read from (and possibly write to) an object's properties.TypedValue Encapsulates an object and aTypeDescriptor

expressions.ConstructorExecutor Executors are built by resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.ConstructorResolver A constructor resolver attempts locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.EvaluationContext Expressions are executed in an evaluation context.EvaluationException Represent an exception that occurs during expression evaluation.Expression An expression capable of evaluating itself against context objects.ExpressionException Super class for exceptions that can occur whilst processing expressions.MethodExecutor MethodExecutors are built by the resolvers and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.MethodResolver A method resolver attempts locate a method and returns a command executor that can be used to invoke that method.Operation Supported operations that anOperatorOverloader
can implement for any pair of operands.OperatorOverloader By default the mathematical operatorsOperation
support simple types like numbers.ParseException Represent an exception that occurs during expression parsing.ParserContext Input provided to an expression parser that can influence an expression parsing/compilation routine.PropertyAccessor A property accessor is able to read from (and possibly write to) an object's properties.TypeComparator Instances of a type comparator should be able to compare pairs of objects for equality.TypeConverter A type converter can convert values between different types encountered during expression evaluation.TypedValue Encapsulates an object and aTypeDescriptor
that describes it.TypeLocator Implementers of this interface are expected to be able to locate types.org.springframework.expression.common使用的org.springframework.expression中的类 类 说明 EvaluationContext Expressions are executed in an evaluation context.EvaluationException Represent an exception that occurs during expression evaluation.Expression An expression capable of evaluating itself against context objects.ExpressionParser Parses expression strings into compiled expressions that can be evaluated.ParseException Represent an exception that occurs during expression parsing.ParserContext Input provided to an expression parser that can influence an expression parsing/compilation routine.TypeConverter A type converter can convert values between different types encountered during expression evaluation.TypedValue Encapsulates an object and aTypeDescriptor
