没有 jackson-modules-java8
它构建成功。
<dependency>

<version>${jackson.version}</version>

有个的问题,但是没有解决我的问题。我的 pom 文件中有 maven 依赖项。如果没有别的办法,我最后会做的就是手动下载东西。
我删除了 java8-模块。
我改用
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>${jackson.version}</version>
</dependency>
我不知道jackson-modules-java8
和jackson-datatype-jsr310
有什么区别,但后者对我有用。
创建对象映射器时,注册JavaTimeModule
。
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new JavaTimeModule());
在 GitHub jackson-datatype-jsr310
页面上您可以阅读:
(DEPRECATED) -- moved under jackson-modules-java8
repo:
https://github.com/FasterXML/jackson-modules-java8
在 linked 页面上,您可以找到有关 java8
模块的信息:
Note that the parent project -- jackson-modules-java8 -- is ONLY used
as parent pom by individual "child" modules, and DOES NOT have
dependencies on them.
以及应该如何使用新模块:
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-parameter-names</artifactId>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
