1.2.83版本 long类型反序列化位数超出后会无感处理溢出

版本

            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>fastjson</artifactId>

            </dependency>

Debug过程

基础类型long处理在Long.MAX 的长度内都能正确处理反序列化，出现超出大小后报错，但超过长度会静默处理溢出（初步判断是这样的，极少的情况发现会报错，暂时没摸清这里的原因，按照以下我的测试记录可复现），导致接收数据出问题，经测试，包装类型Long，基础类型int，包装类型Integer均无此问题，只有基础类型long存在该现象

测试类

@Data
public class Test implements Serializable {

    private LocalDate localDate;

    private LocalDateTime createTime;

    private Date date;

    private Long longClassType;

    private long longType;

    private Integer integerType;

    private int intType;

    private String str;
}

Controller

@RestController
@RequestMapping("/test")
public class TestController{

    @PostMapping
    public Test queryDate(@RequestBody Test test) {
        System.out.println(Integer.MAX_VALUE);
        System.out.println(Integer.MIN_VALUE);
        System.out.println(Long.MAX_VALUE);
        System.out.println(Long.MIN_VALUE);
        return test;
    }
