问题：spark实时处理数据报错 Spark Structured Streaming kafka 报错 Caused by: com.fasterxml.jackson.databind.JsonMappingException...storm-kafka-client', version: '1.2.2'){ //解决与spark core jackson版本冲突 exclude group:"com.fasterxml.jackson.core...compile (group: 'org.apache.kafka', name: 'kafka_2.11', version: '1.1.1'){ exclude group:"com.fasterxml.jackson.core
加序列化（java 的实体类 implement Serializable等）或者处理序列化（改成jsonString就是一种处理方式哦）。
FasterXMLjackson-databind版本到2.9.9.2,2.10.0,2.7.9.6,2.8.11.4 2、不开启Jackson的defaultTyping选项 六、参考 https://github.com/FasterXML.../jackson-databind/issues/2389 https://github.com/FasterXML/jackson-databind/issues/2387 https://cve.mitre.org
2.9.10.8之前的FasterXML jackson-databind 2.x对序列化小工具和打字之间的交互处理不当，与com.oracle.wls.shaded.org.apache.xalan.lib.sql.JNDIConnectionPool...1.0-SNAPSHOT com.fasterxml.jackson.core...1.1 poc.java import com.fasterxml.jackson.databind.ObjectMapper

解决fasterxml中string字符串转对象json格式错误问题。 springboot中jackson使用的包是fasterxml的。...可以通过如下代码，将一个形如json格式string转为一个java对象： com.fasterxml.jackson.databind.ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper...设备编号：1101'} 错误信息是： com.fasterxml.jackson.core.JsonParseException: Unexpected character ('s' (code 115...)): was expecting double-quote to start field name 意思就是：fasterxml期望字段名带有双引号,也就是期望是这样的： {"success":2,"...解决： com.fasterxml.jackson.databind.ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper
问题描述 查询的是时候报错com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Direct self-reference...debug调式 发现代码在自己设置自己领导的时候 堆栈内存溢出 原因 堆栈内存溢出是因为自己里面有自己调用toString 就像递归无限循环一样 那么堆栈内存溢出 为什么会导致com.fasterxml.jackson.databind.exc.InvalidDefinitionException
