注释类型 JsonAutoDetect

@Target(value=TYPE)
@Retention(value=RUNTIME)
public @interface JsonAutoDetect

Class annotation that can be used to define which kinds of Methods are to be detected by auto-detection. Auto-detection means using name conventions and/or signature templates to find methods to use for data binding. For example, so-called "getters" can be auto-detected by looking for public member methods that return a value, do not take argument, and have prefix "get" in their name.

Pseudo-value NONE means that all auto-detection is disabled for the specific class that annotation is applied to (including its super-types, but only when resolving that class). Pseudo-value ALWAYS means that auto-detection is enabled for all method types for the class in similar way.

The default value is ALWAYS: that is, by default, auto-detection is enabled for all classes unless instructed otherwise.

Starting with version 1.5, it is also possible to use more fine-grained definitions, to basically define minimum visibility level needed. Defaults are different for different types (getters need to be public; setters can have any access modifier, for example).

元素详细资料

value

public abstract JsonMethod[] value

Types of property elements (getters, setters, fields, creators) that can be auto-detected. NOTE: as of 1.5, it is recommended that instead of defining this property, distinct visibility properties are used instead. This because levels used with this method are not explicit, but global defaults that differ for different methods. As such, this property can be considered deprecated and only retained for backwards compatibility.
