方法名：getBindings

ScriptEngine.getBindings介绍

[英]Retrieves a reference to the associated bindings for the specified scope. Possible scopes are: GLOBAL_SCOPE : if the ScriptEngine was created by ScriptingEngineManager then GLOBAL_SCOPE of it is returned (or null if there is no GLOBAL_SCOPE stored in the ScriptEngine). ENGINE_SCOPE : the set of key-value pairs stored in the ScriptEngine is returned.
[中]检索对指定范围的关联绑定的引用。可能的作用域包括：全局作用域：如果ScriptEngineManager创建了ScriptEngine，则返回其全局作用域（如果ScriptEngine中没有存储全局作用域，则返回null）。ENGINE_SCOPE：返回存储在ScriptEngine中的键值对集。
