2.0.27版本，空字符串转map类型，报异常。fastjson1 不报异常，直接返回null。不兼容。

@Data @Builder class PersonTest {

private int pSsrc;

private String pUserId;

private boolean flag;

private Map<String, String> map;

public PersonTest(int pSsrc, String pUserId, boolean flag, Map<String, String> map) {
    super();
    this.pSsrc = pSsrc;
    this.pUserId = pUserId;
    this.flag = flag;
    this.map = map;
}

}

String t1 = "{"flag":false,"pSsrc":1,"pUserId":"","map":""}"; PersonTest t =JSON.parseObject(t1, PersonTest.class);
