Spring boot通用字符串修剪序列化

public class MyEntity {
    private String myString;

    // getter and setter
}

public class MyEntity {
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    @JsonDeserialize(using = TrimStringDeserializer.class)
    private String myString;

    // getter and setter
}

public class TrimStringDeserializer extends JsonDeserializer<String> {
    @Override
    public String deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        String value = jsonParser.getValueAsString();
        if (value != null) {
            return value.trim();
        }
        return null;
    }
}

@RestController
public class MyController {
    @PostMapping("/my-endpoint")
    public void myEndpoint(@RequestBody MyEntity myEntity) {
        // 处理修剪后的字符串
    }
}
