前几天在项目中使用swagger时发现一个诡异的问题，后来发现是同时使用了@Accessors(chain = true) 和 @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)这两个注解引起的。
问题如图，password这个字段被识别成了一个对象
一时找不出原因，于是我搭建了一个简单的项目来试错，结果发现这两个注解只要不同时使用，就没有问题，实验关键代码如下

@Accessors(chain = true)

private static final long serialVersionUID = 1L;
@Schema(description = "username", example = "john")
@Size(min = 6, max = 20, groups = { Groups.Default.class })

@Schema(description = "password", example = "acb123", accessMode = Schema.AccessMode.WRITE_ONLY)
@NotNull(groups = { Groups.Default.class })

@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private String password;
}

由于使用了lombok，所以去看了一下最后生成的代码(UserA)，发现有以下代码

@JsonProperty(
access = Access.WRITE_ONLY
)
private String password;
@JsonProperty(
access = Access.WRITE_ONLY
)
public UserA setPassword(final String password) {
this.password = password;
return this;
}

所以问题就清楚了，实际使用中发现如果使用了knife4j的UI，password还会被显示为嵌套对象。
