About how jackson parses json string

JSON (JavaScriptObjectNotation) is a lightweight data exchange format that has become a common format for data exchange between web applications. PHP's json_encode() function can convert an array or object into a JSON string. This article will introduce how to use PHP's json_encode() function, including syntax, parameters, return values, and specific examples. Syntax The syntax of the json_encode() function is as follows: st

AJackson is a Java JSON API that provides several different ways to process JSON. We can convert CSV data to JSON data using the CsvMapper class, which is a special ObjectMapper with extended functionality to convert POJOs into CsvSchema instances. We can build an ObjectReader with default settings using the reader() method. In order to convert we need to import com.fasterxml.jac

JSONObject can parse text in a string to generate a Map type object. Enumerations can be used to define collections of constants, and we can use enumerations when we need a predefined list of values ​​that does not represent some kind of numeric or textual data. We can convert JSON objects into enumerations using the readValue() method of the ObjectMapper class. In the example below, we can use the Jackson library to convert/deserialize a JSON object into a Java enumeration. Example importcom.fasterxml.jackson.databind.*;publicclassJSONToEnumTest{&

[Vulnerability Notice] On February 19, NVD issued a security notice disclosing a remote code execution vulnerability (CVE-2020-8840) in jackson-databind caused by JNDI injection, with a CVSS score of 9.8. The affected version of jackson-databind lacks certain xbean-reflect/JNDI blacklist classes, such as org.apache.xbean.propertyeditor.JndiConverter, which can lead to attackers using JNDI injection to achieve remote code execution. At present, the manufacturer has released a new version to complete the vulnerability repair. Relevant users are requested to upgrade in time for protection. Since the S used in the project

Jackson is a Java-based library that is useful for converting Java objects to JSON and JSON to Java objects. JacksonAPI is faster than other APIs, requires less memory area, and is suitable for large objects. We use the writeValueAsString() method of the XmlMapper class to convert the POJO to XML format, and the corresponding POJO instance needs to be passed as a parameter to this method.

1. Background: Some sensitive information in the project cannot be displayed directly, such as customer mobile phone numbers, ID cards, license plate numbers and other information. Data desensitization is required when displaying to prevent the leakage of customer privacy. Desensitization means treating part of the data with desensitization symbols (*). 2. When the target returns data from the server, use Jackson serialization to complete data desensitization to achieve desensitized display of sensitive information. Reduce the amount of repeated development and improve development efficiency to form unified and effective desensitization rules. It can be based on the desensitize method of rewriting the default desensitization implementation to realize the desensitization requirements of scalable and customizable personalized business scenarios. 3. Main implementation 3.1 Based on Jackson Custom desensitized serialization implementation of StdSerializer: all standard
