解析 json 数组

1. 首先先 导入 json 包 ：jackson-mapper-asl-1.9.13 jackson-core-asl-1.9.9

2.. import java.util.List;

import org.codehaus.jackson.map.ObjectMapper;

public class jsonTest {

public static void main(String[] args) throws Exception{

String json = "[{\"pid\":1,\"count\":2},{\"pid\":1,\"count\":2},{\"pid\":1,\"count\":2}]";

ObjectMapper mapper = new ObjectMapper();

List<Object> list = mapper.readValue(json, List.class);

System.out.println(list);

}

}

打印 结果 ：

[{pid=1, count=2}, {pid=1, count=2}, {pid=1, count=2}]
