Java IDE不显示Lombok为Jackson注释类生成的getter和setter

我在Java项目中使用Intellij Idea 2019.1.2社区版。我有一个jackson2.9.6注释的POJO，它使用lombok1.18.0为POJO生成getter和setter。我有一些“客户机”代码将示例Json文本反序列化到Pojo类。反序列化工作正常，没有任何编译问题，pojo的类文件实际上拥有所有的getter和setter。但是，IDE在“客户机”代码中没有显示pojo的任何getter和setter

使IDE的缓存失效并重新启动它并不能解决问题。如何找出此问题的原因并进行修复

示例Json:

{
    "id": "1234",
    "number" : 1,
    "items" : [
        {
            "item1" : "blah...more fields."
        },
        {
            "item2" : "blah...more fields."
        }
    ],
    "someBigObject:" : {
        "my_comment" : "i don't really care about validating this object.",
        "fields" : "more fields here",
        "objects" : "more objects here"
    },
    "message" : "hello"
}

上述Json的Pojo，生成人：

    "id": "1234",
    "number" : 1,
    "items" : [
        {
            "item1" : "blah...more fields."

        {
            "item2" : "blah...more fields."
        }
    ],
    "someBigObject:" : {
        "my_comment" : "i don't really care about validating this object.",
        "fields" : "more fields here",
        "objects" : "more objects here"
    },
    "message" : "hello"

要解决此问题，您需要：

1-Lombok插件安装在Intellij IDEA中。

添加Lombok IntelliJ插件以添加对IntelliJ的Lombok支持：

转到文件>设置>插件 点击浏览存储库。。。 搜索Lombok插件 点击安装插件 重新启动IntelliJ IDEA

2-已为项目启用注释处理。

是否在IntelliJ设置中启用了注释处理器？另见@MarkRotteveel-谢谢。这给了我解决问题的提示。您是否在IntelliJ设置中启用了注释处理器？另见@MarkRotteveel-谢谢。这给了我解决问题的提示。
