如何从一行文字创建字典？

text = '{"key1": "value1", "key2": "value2"}'
dictionary = eval(text)
print(dictionary)

{'key1': 'value1', 'key2': 'value2'}

import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.Map;

public class Main {
    public static void main(String[] args) throws Exception {
        String text = "{\"key1\": \"value1\", \"key2\": \"value2\"}";
        ObjectMapper objectMapper = new ObjectMapper();
        Map<String, String> dictionary = objectMapper.readValue(text, Map.class);
        System.out.println(dictionary);
    }
}

{key1=value1, key2=value2}

var text = '{"key1": "value1", "key2": "value2"}';
var dictionary = JSON.parse(text);
console.log(dictionary);

{ key1: 'value1', key2: 'value2' }
