Spring Boot忽略ObjectMapper模块 [英] Spring Boot ignore ObjectMapper module

问题描述

在应用程序上下文中，我已经注册了一个ObjectMapper模块：

In application context I have registered an ObjectMapper module:

@Bean
public SimpleModule jsr310Module() {
    final SimpleModule module = new SimpleModule();
    module.addSerializer(new LocalDateSerializer());
    module.addDeserializer(LocalDate.class, new LocalDateDeserializer());
    return module;
}

我试图调试并加载它（或者至少是方法 public void setupModule（SetupContext context）在启动时执行）
但是当我调用一个返回带有LocalDate的对象的rest API时，我的反序列化器将被忽略。

I tried to debug and it is loaded (or at least the method public void setupModule(SetupContext context) is execute on boot) but when I call a rest API that return an object with a LocalDate my deserializer is ignored.

一些解决问题的提示？

推荐答案

根据 Spring Boot文档，要配置ObjectMapper，您可以自己定义bean并使用 @Bean 和 @Primary 对其进行注释。在那里你可以注册模块。或者你可以添加一个类型为 Jackson2ObjectMapperBuilder 的bean，你可以自定义ObjectMapper。

According to the Spring Boot documentation, to configure the ObjectMapper you can either define the bean yourself and annotate it with @Beanand @Primary. There you can register the module. Or you can add a bean of type Jackson2ObjectMapperBuilderwhere you can customize the ObjectMapper.
