第一步：在pom.xml中添加依赖;
<dependency> ??????????????<groupId>com.alibaba</groupId> ??????????<artifactId>fastjson</artifactId> ??????????????<version>1.2.47</version> ?????????</dependency>
第二步：编写测试代码；
import java.util.Map;
import com.alibaba.fastjson.JSON;
public class Demo1 {
public static void main(String[] args) {
String str = "{\"id\":11,\"status\":\"Analyze\",\"severity\":\"Review\"}";
Map<String,Object> mapType = JSON.parseObject(str,Map.class);
for (Object obj : mapType.keySet()){
System.out.println(obj+" = "+mapType.get(obj));
}
}
}
public static void main(String[] args) {
String str = "{\"id\":11,\"status\":\"Analyze\",\"severity\":\"Review\"}";
Map<String,Object> mapType = JSON.parseObject(str,Map.class);
for (Object obj : mapType.keySet()){
System.out.println(obj+" = "+mapType.get(obj));
}
}
}
第三步：查看运行结果；
Json字符串转map集合
