Lombok and jackson - Conflicting/ambiguous property name definitions

问题

I get a WARN message:

com.fasterxml.jackson.databind.JsonMappingException: Conflicting/ambiguous property name definitions (implicit name 'balance'): found multiple explicit names: [{}Balance, Balance], but also implicit accessor: [method ResponseVO#getBalance(0 params)][visible=true,ignore=false,explicitName=false]

I have latest lombok 1.18.10 and fasterxml.jackson-version 2.7.5

I found similar issue but it should have been fixed in 2.7.4 (closed)

Jackson 2.7.1 and Lombok: 'Conflicting/ambiguous property name definitions' #1122

I think this can be changed for 2.7.4 after all, can fix this.

Code:

@Data
@AllArgsConstructor(access = AccessLevel.PUBLIC)
@NoArgsConstructor
public class ResponseVO implements Serializable {

    private static final long serialVersionUID = 1;
    @JacksonXmlProperty(localName = "Balance")
    @JsonProperty("Balance")
    @JacksonXmlElementWrapper(useWrapping = false)
    List<BalanceResponseVO> balance;

Is it relevant warning ? how can I fix/remove this warning?

It seems that new Lombok version added @JsonProperty("Balance") to generated setter also and create this confusion

EDIT

Issue fixed when I removed @JsonProperty("Balance") which is actually unneeded in my case

回答1:

We upgrade Lombok version and it now added @JsonProperty("Balance") also to generated setter

This duplicate @JsonProperty created a WARN in log and also failed creating response (without exception)

I removed @JsonProperty("Balance") which is actually redundant/unneeded in my case and it works

Note changing to private didn't fixed the issue

Lombok change:

FEATURE: Lombok now knows exactly how to treat @com.fasterxml.jackson.annotation.JsonProperty and will copy it to the right places for example when making builders. Issue #1961 Issue #1981
