大神帮我讲解下，java中string字符串怎么转成list？
str = "[{"dept_count":0,"online_count":0,"offline_count":0,"dept_id":"0.001","dept_name":"test1"},{"dept_count":0,"online_count":0,"offline_count":0,"dept_id":"0.002","dept_name":"test2"},{"dept_count":0,"online_count":0,"offline_count":0,"dept_id":"0.003","dept_name":"test3"}]"public class testtPO extends PO {
private String dept_count;
private String online_count;
private String offline_count;
private String dept_id;
省略set、get...
}
怎么把str转换成list，求指点
