Lombok使用坑之属性不区分大小写

实验环境说明：

1：JDK 1.8.0_241

2：IDEA IntelliJ 2018.3

3：Lombok 1.18.8

由于Fastjson漏洞比较多，所以，我调研换用Jackson是否OK，在实验的过程中发现了Lombok的一个细节，如果不注意，可能存在问题，问题比较简单，代码一贴基本就能看出来了！

4：源码如下所示

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class TestLombok {
    private long _long;
    private Long _Long;

    private byte _byte;
    private Byte _Byte;

    private double _double;
    private Double _Double;

    private boolean _boolean;
    private Boolean _Boolean;

    private float _float;
    private Float _Float;

    private String myName;
    private String mYnAmE;
    private String MyNaMe;
    private String my_name;
}

5：生成的反编译字节码如下所示

6：结论

     6-1：自动生成的Setter/Getter方法少了，貌似属性不区分大小写

     6-2：equals方法也是存在问题，某些属性的Getter方法使用错误
