类 Jackson2ObjectMapperBuilder

java.lang.Object

cn.taketoday.http.converter.json.Jackson2ObjectMapperBuilder

public class Jackson2ObjectMapperBuilder
extends Object

A builder used to create ObjectMapper instances with a fluent API.

It customizes Jackson's default properties with the following ones:

• MapperFeature.DEFAULT_VIEW_INCLUSION is disabled
• DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES is disabled

It also automatically registers the following well-known modules if they are detected on the classpath:

• jackson-datatype-jdk8: support for other Java 8 types like Optional
• jackson-datatype-jsr310: support for Java 8 Date & Time API types
• jackson-module-kotlin: support for Kotlin classes and data classes

Compatible with Jackson 2.9 to 2.12.

从以下版本开始:

4.0

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 today either (see findModulesViaServiceLoader). As a consequence, specifying an empty list here will suppress any kind of module detection.

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.
