I tried adding the path where the jar resides, but I get the same error. I have multiple Jackson annotations, but the one I recently added, JsonAlias idn't seen. java -cp "/dirwhereclassresides/java" Test Exception in thread "main" : com/fasterxml/jackson/annotation/JsonViewĪt .introspect.JacksonAnnotationIntrospector.(JacksonAnnotationIntrospector.java:37)Īt .ObjectMapper.(ObjectMapper.java:291)Ĭaused by: : .JsonViewĪt $1.run(URLClassLoader.java:366)Īt $1.run(URLClassLoader.java:355)Īt (Native Method)Īt (URLClassLoader.java:354)Īt (ClassLoader.java:425)Īt (ClassLoader.java:358) I am using Jackson annotations in my Java/Maven project. To map ownerName, we unpack the nested owner object to a Map and extract its name property. However, I can't seem to get java find the jar & execute the class. To map the nested brandName property, we first need to unpack the nested brand object to a Map and extract the name property. Jackson contains a set of annotations that affect both the reading of Java objects from JSON, as well as the writing of Java objects into JSON. JsonProperty and JsonView are the two generally used annotations at the time of serialization and deserialization. I am able to compile the class with no issues, and produce Test.class. General annotations include several basic annotations which we use in serialization and deserialization. Let's understand each one of them one by one with an example. Two of the imports that I am using could not be resolved: import .JsonParseException import .JsonMappingException I managed to resolve the re by downloading the version 2.2.3 and adding it to jars in the build path. Jackson library provides several serialization annotations such as JsonSerialize, JacksonGetter, JsonAnyGetter, etc. I am trying to write a program that parse JSON in java. I placed jackson-databind-2.9.9.1.jar in /dirwherejarresides/jdk/jre/lib/ext. Serialization annotations are used when we serialize Java objects into a Json string. ObjectMapper objectMapper = new ObjectMapper() I wrote a simple test class to get it working. I need to use jackson to handle some JSON in my code.
