问题

在尝试将以下属性保存到Couchbase的Person实体中时遇到了问题，但无法保存并出现错误，请参见下面的错误日志。

注意: 在Spring Boot 3.X版本之后，Spring Data Couchbase 5.X版本之后出现的问题，在4.X版本中没有出现。

我看到从下面的方法中调用了getPropertyAccessor(val)方法：

private CouchbaseDocument writeMapInternal(final Map<? extends Object, Object> source, final CouchbaseDocument target, TypeInformation<?> type, CouchbasePersistentProperty prop)

这个调用导致了问题，而且getPropertyAccessor的结果从未被使用。

如何解决？

实体：

@Data
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
@Document
public class Person {

    @Id
    private String id;
    @Field
    private Map<String, Version> versions;
    @Field
    private Map<String, Map<String, String>> releaseVersions;

    public Person(){

    }
}

错误：

2023-05-09 16:36:27 Unable to make field private transient java.util.HashMap java.util.HashSet.map accessible: module java.base does not "opens java.util" to unnamed module @10656728 ERROR_MESSAGE=Unable to make field private transient java.util.HashMap java.util.HashSet.map accessible: module java.base does not "opens java.util" to unnamed module @10656728
java.lang.reflect.InaccessibleObjectException: Unable to make field private transient java.util.HashMap java.util.HashSet.map accessible: module java.base does not "opens java.util" to unnamed module @10656728
...
（错误信息继续）

英文:

Tried to save Person entity with below attributes in couch base, but not able to save getting error, see below error log.

Note: Issue in Spring boot 3.X onwards, Spring-data -couch 5.X onwards not facing in 4.X

I see call of method getPropertyAccessor(val) called from

private CouchbaseDocument writeMapInternal(final Map&lt;? extends Object, Object&gt; source, final CouchbaseDocument target, TypeInformation&lt;?&gt; type, CouchbasePersistentProperty prop)

is causing issue and and result of getPropertyAccessor is never used.

How to resolve?

Entity

@Data
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
@Document
public class Person {

    @Id
    private String id;
    @Field
    private Map&lt;String, Version&gt; versions;
    @Field
    private Map&lt;String,Map&lt;String,String&gt;&gt; releaseVersions;

    public Person(){

    }
}
