复测过，升级到fastjson 2.0.10兼容版本和fastjson2 2.0.10 不会抛出异常。 json字符串里面params属性的值是null 转换后的bo的params还是null，没有赋值

使用了2.0.10版本是当使用了lombok的@accessors(chain = true)注解的时候依然会报错.

@Setter
@Getter
@Accessors(chain = true)
public class WinningInformationBo{
    private boolean isSuccess;
    private String wxId;
    private Map<String, String> parems;
}

编译后的类为:

public class WinningInformationBo{
    private boolean isSuccess;
    private String wxId;
    private Map<String, String> parems;

    public TestVO() {
    }

    public TestVO setSuccess(final boolean isSuccess) {
        this.isSuccess = isSuccess;
        return this;
    }

    public TestVO setWxId(final String wxId) {
        this.wxId = wxId;
        return this;
    }

    public TestVO setParems(final Map<String, String> parems) {
        this.parems = parems;
        return this;
    }

    public boolean isSuccess() {
        return this.isSuccess;
    }

    public String getWxId() {
        return this.wxId;
    }

    public Map<String, String> getParems() {
        return this.parems;
    }
}

@Setter
@Getter
@accessors(chain = true)
public class WinningInformationBo {
private boolean isSuccess;
private String wxId;
private Map<String, String> parems;
}

String str3 = "{"wx_id":"xxx","success":true,"parems":null}";
WinningInformationBo bo = JSON.parseObject(str3, WinningInformationBo.class);
此时会报错抛出异常。
使用fastjson 2.0.10兼容版本和fastjson2 2.0.10都会报错。
期望值是null时不用赋值

parems 为{}是不会抛异常，但params=null的时候确实会抛异常
