ObjectMapper为JAX-RS /
Jersey应用程序配置的一般方法是使用
ContextResolver。例如
@Providerpublic class ObjectMapperContextResolver implements ContextResolver<ObjectMapper> { private final ObjectMapper mapper; public ObjectMapperContextResolver() { mapper = new ObjectMapper(); mapper.setPropertyNamingStrategy( PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES ); } @Override public ObjectMapper getContext(Class<?> type) { return mapper; }}应该在程序包扫描中将其提取，或者如果它不在程序包范围内，则可以显式注册它
public JerseyConfig() { register(new ObjectMapperContextResolver()); // Or if there's is an injection required // register it as a .class instead of instance}在
ContextResolver打包和解包时被调用。序列化或反序列化的类/类型将传递给
getContext方法。因此，您甚至可以将多个映射器用于不同类型，甚至更多用例。
更新
从Spring Boot 1.4开始，您可以只创建一个
ObjectMapperSpring bean，然后Spring
Boot将为
ContextResolver您创建，并使用您的
ObjectMapper
// in your `@Configuration` file.@Beanpublic ObjectMapper mapper() {}
