【JSON序列化】Jackson实现Json序列化

一、pom.xml

// https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.13.0'

    // https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.13.0'

    // https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-annotations', version: '2.13.0'

二、代码实现

ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.writeValueAsString(ret);
