如何解析json spring boot的某些字段

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
</dependency>

public class MyData {
    private String field1;
    private int field2;
    // 其他字段及对应的getter和setter方法
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class MyController {
    public void parseJson(String jsonString) {
        try {
            ObjectMapper objectMapper = new ObjectMapper();
            MyData myData = objectMapper.readValue(jsonString, MyData.class);
            // 对解析后的数据进行处理
            System.out.println(myData.getField1());
            System.out.println(myData.getField2());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
