方法详细资料

• setBase64EncodeByteArrays

  public void setBase64EncodeByteArrays​(boolean base64EncodeByteArrays)

  Whether to Base64-encode byte[] properties when reading and writing JSON.

  When set to true, a custom TypeAdapter will be registered via GsonBuilder.registerTypeHierarchyAdapter(Class, Object) which serializes a byte[] property to and from a Base64-encoded String instead of a JSON array.

  NOTE: Use of this option requires the presence of the Apache Commons Codec library on the classpath when running on Java 6 or 7. On Java 8, the standard Base64 facility is used instead.

• setSerializeNulls

  public void setSerializeNulls​(boolean serializeNulls)

  Whether to use the GsonBuilder.serializeNulls() option when writing JSON. This is a shortcut for setting up a Gson as follows:

   new GsonBuilder().serializeNulls().create();
   

• setPrettyPrinting

  public void setPrettyPrinting​(boolean prettyPrinting)

  Whether to use the GsonBuilder.setPrettyPrinting() when writing JSON. This is a shortcut for setting up a Gson as follows:

   new GsonBuilder().setPrettyPrinting().create();
   

• setDisableHtmlEscaping

  public void setDisableHtmlEscaping​(boolean disableHtmlEscaping)

  Whether to use the GsonBuilder.disableHtmlEscaping() when writing JSON. Set to true to disable HTML escaping in JSON. This is a shortcut for setting up a Gson as follows:

   new GsonBuilder().disableHtmlEscaping().create();
   

• setDateFormatPattern

  public void setDateFormatPattern​(String dateFormatPattern)

  Define the date/time format with a SimpleDateFormat-style pattern. This is a shortcut for setting up a Gson as follows:

   new GsonBuilder().setDateFormat(dateFormatPattern).create();
   

• afterPropertiesSet

  public void afterPropertiesSet()

  从接口复制的说明: InitializingBean
  Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

  This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

  指定者:

  afterPropertiesSet 在接口中 InitializingBean

• getObject

  public com.google.gson.Gson getObject()

  Return the created Gson instance.

  指定者:

  getObject 在接口中 FactoryBean<com.google.gson.Gson>

  返回:

  an instance of the bean (can be null)

  FactoryBeanNotInitializedException

• getObjectType

  public Class<?> getObjectType()

  从接口复制的说明: FactoryBean
  Return the type of object that this FactoryBean creates, or null if not known in advance.

  This allows one to check for specific types of beans without instantiating objects, for example on autowiring.

  In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

  This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

  NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

  指定者:

  getObjectType 在接口中 FactoryBean<com.google.gson.Gson>

  返回:

  the type of object that this FactoryBean creates, or null if not known at the time of the call

• isSingleton

  public boolean isSingleton()

  从接口复制的说明: FactoryBean
  Is the object managed by this factory a singleton? That is, will FactoryBean.getObject() always return the same object (a reference that can be cached)?

  NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

  The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

  NOTE: This method returning false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.

  指定者:

  isSingleton 在接口中 FactoryBean<com.google.gson.Gson>

  返回:

  whether the exposed object is a singleton
