方法详细资料

• createXmlMapper

  public Jackson2ObjectMapperBuilder createXmlMapper​(boolean createXmlMapper)

  If set to true, an XmlMapper will be created using its default constructor. This is only applicable to build() calls, not to configure(com.fasterxml.jackson.databind.ObjectMapper) calls.

• dateFormat

  public Jackson2ObjectMapperBuilder dateFormat​(DateFormat dateFormat)

  Define the format for date/time with the given DateFormat.

  Note: Setting this property makes the exposed ObjectMapper non-thread-safe, according to Jackson's thread safety rules.

• modules

  public Jackson2ObjectMapperBuilder modules​(Module... modules)

  Specify one or more modules to be registered with the ObjectMapper. Multiple invocations are not additive, the last one defines the modules to register.

  Specify either this or modulesToInstall(com.fasterxml.jackson.databind.Module...), not both.

  从以下版本开始:

  4.1.5

  另请参阅:

  modules(List), Module

• modules

  public Jackson2ObjectMapperBuilder modules​(List<Module> modules)

  Set a complete list of modules to be registered with the ObjectMapper. Multiple invocations are not additive, the last one defines the modules to register.

  Note: If this is set, no finding of modules is going to happen - not by Jackson, and not by Spring either (see findModulesViaServiceLoader). As a consequence, specifying an empty list here will suppress any kind of module detection.

  Specify either this or modulesToInstall(com.fasterxml.jackson.databind.Module...), not both.

  另请参阅:

  modules(Module...), Module

• modulesToInstall

  public Jackson2ObjectMapperBuilder modulesToInstall​(Module... modules)

  Specify one or more modules to be registered with the ObjectMapper. Multiple invocations are not additive, the last one defines the modules to register.

  Modules specified here will be registered after Spring's autodetection of JSR-310 and Joda-Time, or Jackson's finding of modules (see findModulesViaServiceLoader), allowing to eventually override their configuration.

  Specify either this or modules, not both.

• findModulesViaServiceLoader

  public Jackson2ObjectMapperBuilder findModulesViaServiceLoader​(boolean findModules)

  Set whether to let Jackson find available modules via the JDK ServiceLoader, based on META-INF metadata in the classpath.

  If this mode is not set, Spring's Jackson2ObjectMapperBuilder itself will try to find the JSR-310 and Joda-Time support modules on the classpath - provided that Java 8 and Joda-Time themselves are available, respectively.

• build

  public <T extends ObjectMapper> T build()
