Jackson注释JsonFormat $Value json java.lang.NoSuchMethodError（jackson注解解析json）

我在我的gradle项目中使用com.fasterxml.jackson.core：jackson-annotations：2.6.0.由于将com.fasterxml.jackson.datatype：jackson-datatype-jsr310：2.6.0添加到我的项目构建文件中,我在运行gradle项目时遇到了这个异常.这是我的错误的堆栈跟踪.

我在课堂上没用过@JsonFormat.但我确实有JsonSerializer和JsonDeserializer注释使用两个类来序列化和反序列化我的zoneddatetime与UTC中的Json.我是第一次进行序列化和反序列化,所以请提出任何建议.

这是我的gradle文件代码：

最佳答案

检查您的项目依赖项.您可能正在使用不兼容的库版本.版本2.7的方法为empty(),版本为2.6.

http://fasterxml.github.io/jackson-annotations/javadoc/2.6/com/fasterxml/jackson/annotation/JsonFormat.Value.html

http://fasterxml.github.io/jackson-annotations/javadoc/2.7.0-rc1/com/fasterxml/jackson/annotation/JsonFormat.Value.html

尝试升级到2.7版.

fastjson报NoSuchMethodError诡异

一个神奇的bug，2017年的一个工程A依赖fastjson1.2.7编译出了一个jar包，fastjson中有一个类SerializeConfig，这个类继承了一个put(Object k,Object v)的方法，所以编译出的jar包字节码里写的方法签名就是descriptor: (Ljava/lang/Object;Ljava/lang/Object;)Z。现在一个工程B使用工程A编译出的jar包，但是工程B里有fastjson的依赖1.2.60，在1.2.7之后（确切版本不知道），SerializeConfig这个类不再继承别人了，自己写了一个put(Type type, ObjectSerializer value)，一个put(Object type, Object value)，这时候有两个put方法。但是在fastjson1.2.60时，作者一不小心，删除了put(Object type,Object value)方法，导致运行时报NoSuchMethodError，注意时Error，不是Exception，在1.2.61，作者恢复了这个方法。另外在研究这个错误的时候，发现有时候报NoClassDefFoundError，有时候报NoSuchMethodError，测试了一下，JVM在第一次加载出错类的时候，会报NoSuchMethodError，然后第二次再加载这个类的时候，直接报NoClassDefFoundError，不再尝试初始化了。

java.lang.NoSuchMethodError: com.alibaba.fastjson.serializer.SerializeConfig.put(Ljava/lang/Object;Ljava/lang/Object;)Z
	at com.XX.bst.XX.common.annotation.XXX.<clinit>(XXXX)
	at Test.lambda$main$0(Test.java:7)
	at java.lang.Thread.run(Thread.java:748)
java.lang.NoClassDefFoundError: Could not initialize class XXXX.XX

Gson2.8.6 版本报错 java.lang.NoSuchMethodError: com.google.gson.JsonParser.parseString (Ljava/lang/String;)

绪

最近在 Scala 的项目中尝试使用 Gson 来做 json 的数据解析；Scala 自带和 Jackson 使用都太过繁琐；

使用 Gson 在 scala 代码如下；唯一的就是需要解析完后需要调用 getAsXXX；嵌套对象需要重复执行这个方法；JsonParser 在 2.8.6 里面 new 方法放弃了。推荐用静态方法；2.8.5 里面，还是通过 new 来实例化 JsonParser；

val json = JsonParser.parseString(s)
val obj = json.getAsJsonObject
println(obj.get("@timestamp"))

但是在项目中，碰到一个错误。NoSuchMethodError。不知道如何下手了；本地跑可以，到集群就崩；错误如下：

java.lang.NoSuchMethodError: com.google.gson.JsonParser.parseString(Ljava/lang/String;)Lcom/google/gson/JsonElement #1077

解决方法

换个低版本的 2.8.5；正常不报错了、

val jsonParser = new JsonParser()
val jsonObj = jsonParser.parse(line).getAsJsonObject
